My Android device isn't recognized by eclipse nor adb anymore.
My OS is Windows 7 64-bit, and I'm using a Nexus 4 with Stock Android 4.4.2.
Here are some details on the problem:
Yesterday I could run Android Projects from eclipse on my device with no problems. The only thing that I did on eclipse, which could have caused this problem, was installing the v7 appcompat support library from a resource to eclipse using this guide on developers.android (https://developer.android.com/tools/support-library/setup.html).
The device is still recognized as a normal multimedia drive in Windows when it's not in debug mode.
The device is in Developers mode and in Debug mode when I try to run an Android Project in eclipse or try to see if it's recognized by adb using adb devices in the console.
The Google USB drivers have been installed through the ADK Manager
The USB OEM drivers for Windows have already been installed according to the tutorial on the android-developers site (see: https://developer.android.com/tools/extras/oem-usb.html)
I tried to restart adb by using the commands adb kill-server and adb start-server, and again checked if the devices was recognized by using adb devices. The device was still not listed on the console.
Restarting windows & eclipse did not fix this problem.
What's the solution to this problem?
UPDATE: Thanks for the replies, the problem is solved (for now).
I tried the following suggestions in this order:
I restarted my device - this did not fix the problem
I set my device to PTP mode - this fixed the problem.
So I reset my device to MTP mode & debug mode again to check if it still would be recognised by adb for some reason. It definitly doesn't get recognised by adb when it's in MTP-mode. I don't know how it got recognised some days ago, because I never setmy device to PTP-mode. Anyway, the solution to my problem is that my Nexus 4 must be in PTP-Mode and of course in debug-mode to get recognised by adb.
I didn't try any other suggestions since my problem got solved with my current drivers.
Generally, I think your USB connection should be set to use MTP (Media Transfer), however, I couldn't get my computer to recognize my device (Nexus 4). Oddly, setting the USB connection to Camera got it working for me.
I recently had this issue (but before that debug over wifi was working fine) and since none of the above answers helped me let me share what I did.
Go to developer options
Find Select USB configurations and click it
Choose MTP (Media Transfer Protocol)
Note: If it's set to this option chose another option such as PTP first then set it to MTP again.
UPDATE:
PTP stands for “Picture Transfer Protocol.” When Android uses this protocol, it appears to the computer as a digital camera.
MTP is actually based on PTP, but adds more features, or “extensions.” PTP works similarly to MTP and is commonly used by digital cameras.
I also faced the same problem and tried almost everything possible from manually installing drivers to editing the winusb.inf file. But nothing worked for me.
Actually, the solution is quite simple. Its always there but we tend to miss it.
Prerequisites
Download the latest Android SDK and the latest drivers from here. Enable USB debugging and open Device Manager and keep it opened.
Steps
1) Connect your device and see if it is detected under "Android Devices" section. If it does, then its OK, otherwise, check the "Other devices" section and install the driver manually.
2) Be sure to check "Android Composite ADB Interface". This is the interface Android needs for ADB to work.
3) Go to "[SDK]/platform-tools", Shift-click there and open Command Prompt and type "adb devices" and see if your device is listed there with an unique ID.
4) If yes, then ADB have been successfully detected at this point. Next, write "adb reboot bootloader" to open the bootloader. At this point check Device Manager under "Android Devices", you will find "Android Bootlaoder Interface". Its not much important to us actually.
5) Next, using the volume down keys, move to "Recovery Mode".
6) THIS IS IMPORTANT - At this point, check the Device Manger under "Android Devices". If you do not see anything under this section or this section at all, then we need to manually install it.
7) Check the "Other devices" section and find your device listed there. Right click -> Update drivers -"Browse my computer..." -> "Let me pick from a list..." and select "ADB Composite Interface".
8) Now you can see your device listed under "Android Devices" even inside the Recovery.
9) Write "adb devices" at this point and you will see your device listed with the same ID.
10) Now, just write "adb sideload [update].zip" and your are done.
Hope this helps.
It may sound silly but in my case the USB cable was too long (even if good quality). It worked with my tablet but not with the phone.
To check this, if you run on Linux run lsusb to make sure that your device is at least officially connect to the usb port.
Try use PdaNet. you can download it from here
It installs missing drivers when you plugin your device.
Obviously make sure you "debug usb" option in "developers options" is on.
Another thing, it's important to uninstall any device's installed driver before using it.
Fundamentally, the issue has to do with not being able to get MTP+ADB working while for example PTP+ADB may work. In my case when I plugged Nexus 5, windows 7 will install only MTP driver completely ignoring ADB. I couldn't find a good solution for this problem anywhere else so here I provide steps (some of the steps I copied from other sources):
0) Unplug Nexus 5. Make sure you selected MTP and ADB.
1) Make sure that sdk\extras\google\usb_driverandroid_winusb.inf in Google SDK had the following lines (in two places in that file):
;Google Nexus (generic)
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2&MI_01
NOTE: VID_18D1 is Google VID, PID_4EE2 is PID for MTP+ADB, MI_01 means that ADB is on interface 1 (MTP is on interface 0).
You can check what is on what interface by plugging Nexus 5 into a Linux system and typing lsusb.
2) first delete all installed Google USB drivers. One good tool is called USBDeview and can be find at the following location:
http://www.nirsoft.net/utils/usb_devices_view.html
Download the tool and run it (there is no need to install it). Take a look at the colored status indicator on the far-left of the USBDeview window. Green indicates the the device functions properly. Pink means the device can unplug and works properly (although it may not actually work properly). Red indicates a disabled USB device. Gray (circled, below) means the device is installed, but not connected.
Second, remove all gray items with the words “Google”, “Linux”, “ADB”, or “Android” in the title.
3) Now delete old cached Google *.inf files. Open a Windows Explorer and navigate to the C:\Windows\INF directory. Somewhere in there there is an "oemN.inf" file (where N is a number that will vary on your system) that is a copy of the android_usb.inf -- the thing to do is to find which file and remove it. Windows keeps a cache of the INF files here and what we found is that sometimes an older cached copy is used instead of a newer version.
One simple way to find which one using the Windows Explorer:
- In the explorer's Search box, enter "androidwinusb86.cat" without the quotes.
- Typically the search will be empty because no filename has this pattern.
- Go to Tools/Folder Options, click Search Tab and click Always search file name and contents. Click Apply
- Search again. This time it should list a few files such as "oem90.inf" (you'll have one or more, with different numbers).
Now use the Windows Explorer and delete the "oemNN.*" files that matched above (only those with androidwinusb in them.).
4) We now want to disable installation of MTP by windows before windows discovers ADB. Now search for wpdmtp.* files in the same directory. Presence of these files will force install MTP disregarding ADB class in the same (composite) device. Move these files out of \inf folder
5) plug in the device again. This time, both MTP and Android ADB driver installation will fail.
6) Find Other devices in the Device Manager and when expanded it should show Nexus 5 and MTP. Right click and update Nexus 5 by navigating to the sdk\extras\google\usb_driver\android_winusb.inf.
Move wpdmtp.* files back to \inf folder. Right click MTP device and update.
7) If necessary, confirm on your Nexus 5 that this PC has access to the phone.
8) If everything went as expected you should see in Device Manager the following:
Expand Android Device. Right click Android Composite ADB Interface, select Properties, choose tab Details, under Property select Hardware Ids. You should see USB\VID_18D1&PID_4EE2&MI_01
Expand Portable devices. Right click Nexus 5, select Properties, choose tab Details, under Property select Hardware Ids. You should see USB\VID_18D1&PID_4EE2&MI_00
With USB connected, on android device Settings > Developer options > Revoke USB debug authorizations USB Debug. Remove the USB and connect again, then "Allow USB debugging".
For those people to whom none of the answers worked, try closing the chrome://inspect/#devices tab in Chrome if it is open. This worked for me.
Go to prompt command and type "adb devices". If it is empty, then make sure you allowed for "MTP Transfer" or similar and you enabled debugging on your phone.
To enable debugging, follow this tutorial:
https://www.kingoapp.com/root-tutorials/how-to-enable-usb-debugging-mode-on-android.htm
Then type "adb devices" again. If a device is listed in there, then it should work now.
Set your environmental variable Path to point to where the adb application is at: [directory of sdk folder]\platform-tools
Enabling Developer mode by tapping on Build Number 7 times worked for me.
Make sure you are connecting with a USB and not a lightning cable. I had this problem trying to connect using a cord with lightning cables on both ends and it would not list the device. But switching to a USB to lightning cable worked.
Check that the USB cable is indeed capable of transferring data. Some cheaper ones, especially those meant to charge non-phone/computer devices, might only support charging.
You can verify this by checking if the device shows up as mountable file system. In Linux, you can also use the command lsusb to check if it's being detected.
Find drivers for your device and install them
That will be the end of your device not detected problems
Windows have driver problems, sometimes messed by overriding the existing driver
You can also try uninstalling driver from Win7 and reinstalling
For those facing problem after upgrading their android device to android 10, same PTP Mode option will work as prescribed by user3135185
I tried all these, but nothing worked. Finally, I changed my old data connection USB-c cable, to a new one. Maybe with updates of windows/android studio, the older USB-c protocols are no longer recognized for transfer.
Download and install Moborobo software on your computer.
Connect your device with USB debugging through USB cable.
Now open moborobo and it will connect to your android.
Stay connected, now your device should recognize as adb devices and get
listed.
I am attempting to install an Android app on my brand new Nexus 10. I have a .apk file. I have downloaded the Android SDK, installed "Android SDK Tools", "Android SDK Platform-tools", and Google USB Driver. I have checked the setting on my Nexus 10 for "Unknown Sources".
When I run "adb devices" from the command terminal, it doesn't list any devices. I attempted to follow this recommendation, because it was identical to a suggestion I had previously found here on Stack Overflow. After following those steps, "adb devices" still returns an empty list and to make it worse, when I connect my Nexus 10 to my PC, Windows doesn't show any folders within the device.
I have undone the steps in that link, along with everything else I have done so far, as well as uninstalling my Nexus 10 from Device Manager and reinstalling it, but I am still not seeing any folders in the device.
Is there anything I am missing to get my device to show up in ADB devices?
What can I do to get Windows to see the folders within the device?
Windows 8 wouldn't recognize my Nexus 10 device. Fixed by Setting the transfer mode to Camera (PTP) through the settings dialogue on the device.
Settings > Storage > Menu > USB Computer connection to "Camera (PTP)"
For Windows 8 users:
After trying every solution given here, with no success, I found this:
Go to Device Manager
Browse my computer for drivers -> Let me pick from a list of device drivers on my computer
Choose Android Device and then Android ADB Interface.
Now I have my devices listed at adb devices.
This situation seems to arise with some ADB drivers. I have encountered the same thing with a couple of Google devices and installing the Universal ADB windows driver has fixed it for me every time.
Use another cable.
Just found out that one of my regular charging cables had Vcc, Gnd pairs, but no Data+, Data-.
https://en.wikipedia.org/wiki/USB#Pinouts
Make sure to Enable USB debugging in Settings -> Developer options
Also, run "adb devices" after getting into the platform tools folder in the Android SDK (unless you have that folder on your system path already), otherwise the command won't be found.
The device may not be visible for debugging if it is in MTP mode. Some devices only work in PTP mode (or even in "charging only" mode).
This can be changed in Settings > Developer Options > Networking > Default USB configuration > PTP.
Also, you'll get a notification on your android device asking you for confirmation about USB configuration setting change and to allow it.
Note: You can turn on developer options by following the link below:
enable developer options
I have found a solution (for Windows 7):
Connect your Nexus 10 to PC
Go to Windows Device Manager
RClick on ADB Interface -> properties
Details -> Hardware Ids.
You will see two records like these:
USB\VID_18D1&PID_4EE2
USB\VID_18D1&PID_4EE2&MI_01
5 Open the android_winusb.inf file (I have it in "C:\Users\<username>\AppData\Local\Android\android-sdk\extras\google\usb_driver" directory)
6 Create such records in [Google.NTx86] and [Google.NTamd64] sections using Hardware Ids from properties of ADB interface:
;Google Nexus 10
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4EE2&MI_01
7 Save the file, and update driver for ADB Interface with showing the path to "C:\Users\\AppData\Local\Android\android-sdk\extras\google\usb_driver" directory
Sometimes ADB loses connection to the device, and needs to be reset. If you have everything else working (ie USB driver installed, Developer settings enabled on the device), and still can't see your device, you need to reset the ADB process.
This is available in the DDMS Perspective (from within Eclipse), Devices tab (the triangle on the far right includes a menu item to perform the reset).
Otherwise from the command line, you can reset it with the following 2 commands:
adb kill-server
then
adb start-server
Enable Developer options in your device. To enable the developer mode, setting->About phone, tap Build number option 8 times continuously
Go to Settings-> Developer options and Turn on USB debugging
From the above steps it didn't work try this step, Go to Settings->Security and turn on Allow Unknown Resources
You have to download the drivers from the SDK manager (extras → Google USB Driver)
Then you have to install the USB driver in Windows (it works for me in Windows 8.1):
(Copy and paste from http://developer.android.com/tools/extras/oem-usb.html#InstallingDriver:)
Connect your Android-powered device to your computer's USB port.
Right-click on "Computer" from your desktop or Windows Explorer, and select "Manage".
Select "Devices" in the left pane.
Locate and expand "Other device" in the right pane.
Right-click the device name (such as Nexus S) and select "Update Driver Software." This will launch the "Hardware Update Wizard".
Select "Browse my computer for driver software" and click "Next."
Click "Browse" and locate the USB driver folder. (The Google USB Driver is located in <sdk>\extras\google\usb_driver\.)
Click "Next" to install the driver.
After downloading the Google drivers via Android SDK Manager (available via Eclipse, Intellij or Android Studio), I had to update the driver in Computer Management > Device Manager > Other Devices > ADB - right clicking and clicking on update driver and browsing for updated driver finally did the trick.
BTW, a total nightmare for me as well. I continue to be bewildered that setting up a dev environment should be the most difficult task imaginable, with each new inexplicable failure leading to another one. Jeesh! Good luck.
On my Windows 8.1 64bit (Nexus 5 did not show up), only manually installing the USB driver fixed it:
http://developer.android.com/sdk/win-usb.html
The "Google USB Driver" in "Android SDK Manager" was installed already.
I still get this once in a while and it usually works if I unplug it and plug it back in a different port. I'm on Linux but had the same thing happen on Windows before.
Installing Samsung Kies and using their tool to reinstall device drivers, is what finally worked for me with my Galaxy S3 and Tab S 8.4
Normally SDB will download the driver in the **android-sdk-windows\extras\google\usb_driver** path
Here are the steps that worked for me:
Enable USB debugging.
Do to device manager, right click on ADB device and click update driver software.
Select "Browse my computer for Driver Software"
Select "Let me pick from list of Device drivers on my computer"
Click on "Have Disk" option.
Select the driver path **android-sdk-windows\extras\google\usb_driver** (path of sdk)
7.Select 1st driver out of list of drivers shown.
And hopefully, it will work.
Edit: I recommend you DO NOT run ADB under VirtualBox if you are using a Windows Host. Somehow I got VirtualBox to lock the device drivers on the host, eventually making it so that the ADB wouldn't work on the client nor the host for any device I plugged in. To fix, I removed VirtualBox extensions on the host and ran http://www.nirsoft.net/utils/usb_devices_view.html to delete the incorrect drivers. I could not get the correct drivers to load while VirtualBox extensions were installed, and this problem was a complete bastard to diagnose and fix.
Edit 2: Also the following is probably out of date, now that Google have released an integrated ADB extension for Chrome.
What an installation nightmare... Here are the steps I needed to get my Nexus 10 recognised on an XP virtual machine running under VirtualBox:
If you get asked to install Nexus 10 drivers, make sure to untick "don't ask again" (you WANT to be asked again!).
Plug in the Nexus 10 USB connection
Turn on debugging in the Nexus 10 settings Developer menu (tap "About Tablet" 7 times to get that menu).
In your virtual machine settings (host), add the samsung Nexus 10 device to the USB Device Filters (important - selecting it from the devices menu didn't seem to work).
In guest install java jre (if you don't have java installed). In Control Panel, change Java settings so that java doesn't run in the browser (to help prevent security issues).
In guest get the adk zip file and put it somewhere permanent. I needed to delete the .android config directory from the user directory because I moved the directory.
Run the SDK Manager.exe - if it doesn't work, try running sdk\tools\android.bat which seems to give better error reporting.
From SDK Manager install the Google USB driver package.
Unplug the Nexus 10 and plug it in again, and install the Google USB driver package.
Restart the guest.
running c:>[...]\sdk\platformtools> adb devices finally shows me the device...
For the Blu Studio 5.5s ADB drivers, you have to go through this hoop. I am certain it is the same with all Blu phones or maybe for all non-Google mfg phones, I am not sure. First of all if you connect the Blu device with USB cable and USB Debuggin off, you will see that Windows 7 loads a generic driver for you to copy on/off files to the phone and SD storage. This will appear when the USB cable is first plugged in and appears as a device icon under Control Panel, Device Manager, Portable Devices, BLU STUDIO 5.5 S (or the device you are working with). Do not bother getting the hardware ID yet - just observe that this happens (which indicates you are good so far and don't have a bad cable or something).
Go to the phone and switch on USB Debugging in the Developer section of your phone. Notice that an additional item appears as an undefined device now in the device manager list, it will have the yellow exclamation mark and it may have the same name of the phone listed as you saw under Portable Devices. Ignore this item for the moment. Now, without doing anything to the phone (it should be already in USB debug mode) go back to the Portable Devices in Device Manager and right-click the BLU STUDIO 5.5 S or whatever phone you are working with that is listed there without the exclamation mark (listed under Portable Devices). Right click on the icon under Portable Devices, in this example the name that appears is BLU STUDIO 5.5 S. On that icon select Properties, Details, and under the pull down, select Hardware IDs and copy down what you see.
For BLU STUDIO 5.5 S I get:
USB\VID_0BB4&PID_0C02&REV_0216&MI_00
USB\VID_0BB4&PID_0C02&MI_00
(Note if you do this out of turn, the HW ID will be different with the phone USB debugging turned off. You want to copy the value that it changes to when the USB debugging is ON)
Now do as the instructions say above, of course customizing the lines you add the the INF file with those relating to your own phone, not the Nexus 10. Here is what to customize; when you downloaded the SDK you should have a file structure expanded from the ZIP such as this:
\adt-bundle-windows-x86_64-20140321\sdk\extras\google\usb_driver
Find the file named: android_winusb.inf in the usb_driver folder
Make a copy of it and name it anything, such as myname.inf
Edit the myname.inf and add the lines as instructed above only modified for your particular phone. For example, for the BLU STUDIO 5.5 S, I added the following 2 lines as instructed in the 2 locations as instructed.
;BLU STUDIO 5.5 S
%SingleAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C02&REV_0216&MI_00
%CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0C02&MI_00
Note that you add these lines to both the 32 and 64 bit sections, matching how the example in the tutorial reads.
Now go back up to the unknown device that appeared in Device Manager when you switched on device USB debugging and right click on this item (has yellow exclamation mark), right click on it and then select Update Driver Software, and then Browse My Computer, Let Me Pick, click on the Have Disk button and browse to find the myname.inf. Continue to agree to all the prompts warning you it might not be the right driver. As the final step, Windows should have identified the device as Android ADB Interface and once that is done, you should be able to go back, open your CMD window and run the command "adb devices" as instructed in this tutorial and now you should see that the phone is now discovered and communicating.
Now you can go have fun with the adb command.
At first Thanks #rmsyk's post.
For my issue and after long time suffering with Meizu C9 Pro witch require just android ADB drivers (no special drivers) referring to manufacturer and it solved in my Windows 7 PC by the bellow steps.
Make Sure to
Install latest version of ADB & Fastboot with the needed drivers.
Enable Developer options & USB Debugging.
Enable Media File Transfer (MTP Mode).
Manually replace C:\Users\USERNAME\.android with the folder included here ,Then kill process 'adb.exe' if found from Windows Task Manager and use adb devices and finally my device listed successfully and just confirm the PC as trusted.
Notes:
Android Studio was uninstalled in earlier time and also i tried to reinstall but was not a solution at all.
Tried adb kill-server & adb start-server but was not a solution too.
As well as the usual settings (enable USB debugging) I also had to select Enable OEM unlock in the Developer options.
This supposedly makes the device less secure, but it's your device and you know what you want to do.
Once checked the device behaved as expected and appears in the adb devices list.
You can always reverse all these settings once you're finished.
Confirm you have the correct platform SDK tools
For Windows 10, had to manually download the latest platform SDK tools from Android as the version supplied through Visual Studio 2017 EMDK for Xamarin was not sufficient. Everything else except adb.exe devices worked.
https://developer.android.com/studio/releases/platform-tools
After the platform tools were manually downloaded, device showed up regardless of USB configuration (charging, MTP, etc.)
Installing an emulator device at this stage is also helpful to see whether the problem is with adb or your physical device.
List of devices attached
12345D1234 device
emulator-5554 device
There could be two reasons why adb devices command is not working for you. Either your phones USB drivers are not installed properly or you have not enabled USB debugging mode.
I created a tool that makes installing USB drivers a one click thing.
Just connect your phone in USB debugging mode to PC.
Run my tool
It will detect and install drivers specific to your phone and also install the latest ADB & Fastboot binaries with it.
The tool is available at my GitHub Repo
It's so easy, just turn off your Android device, and then hold down both "Volume Down" key and "Power" at the same time. Wait a few seconds till it start in recovery mode, done.
Now type adb devices, and you'll see your device.
I had the same problem with my Windows 8. The Android/SDK USB driver was installed correctly, but I forgot to install the USB driver from my phone. After installing the phone USB driver ADB works fine.
I hope this will help.
Turn on debugging in the Nexus settings Developer menu (tap "About Tablet" 7 times to get that menu).
Freaking Google tricks!
Have you had an android update recently? I updated to Lollipop and all the sudden I had no adb devices. Boo! I spent awhile trying a few things to no avail. Then I went into my developer options and lo and behold, "USB debugging" had been turned off. Silly Google. After turning it back on, it immediately showed up and I'm back in business!
GoTo DeviceManager, then right click on the android device and click uninstall driver.
Unplug and plug the device back...then a pop will come on your device while your pc installs the required drivers. Click "allow" on the popup.
You can see your device when you type "adb devices" in command prompt.
For Windows, just end all the processes related to Blue stacks or any such emulator if you are using.
Worked for me.
There's obviously a ton of different problems that could be causing this (and a ton of different solutions to go along with those problems). So think about all the solutions!
If you've gotten this phone and computer pair to work together before, but they aren't working any more, it might be a specific program on your computer rather than a problem on your phone. Some programs install/use their own adb, and only one of these can connect to your phone at a time. I think this makes a race condition, so sometimes it'll connect fine.
Some programs that run adb:
HTC Sync Manager - uninstall this.
chrome://inspect - lets you view localhost on your phone. Just close the window when you're done with it.
To have ADB in MTP mode
If you don't find any ADB device (nothing with exclamation mark) in the device manager (with all developers settings on phone checked), do this:
In Device Manager :
UpdateDriver->Manuel Install->Search on my computer->Select from installed driver list -> then select the one with the word usb in it (not MTP).
Edit: after that, you'll then have 2 or 3 peripheral, one for USB and one for ADB, install adb driver using usual method (see first answers)
For my Nexus 6P downloading drivers from Google helped resolved the issue. Here is the URL with documentation. And here you can download the driver itself.
P.S. I saw some people advice to download some drivers from random places on internet. While this might help it's too dangerous in my mind to download unknown drivers from unofficial places. So the one from Google worked well for me :)
I'm running on Windows 7, and I've updated all the drivers as it says on the Android developer website regarding using hardware devices. However, Eclipse is still not recognising my Nexus 4 when I try to run the application. The Android device chooser pops up, but it doesn't show anything on the hardware section. I've turned debugging, third-party apps, and mock locations all on on my phone as well.
Is this because the phone is still new? Is there a way of making my Nexus work with Eclipse?
Nothing is showing up under ADB devices in the command prompt.
I had a similar sounding situation with my Nexus 4. For me it was an issue with the drivers Windows was installing automatically. I followed the instructions in [Q]Computer won't recognize phone? - Post #8. I had some slight differences on Windows 7.
For me I,
Uninstalled the driver from Device Manager
Let it automatically install the generic 'MTP device driver'
Right clicked on the new device and selected 'Update Driver'
Selected 'Have Disk' and pointed it to [android-sdk-dir]\extras\google
Watched an 'ADB' driver install.
Opened Eclipse to successfully run on my Nexus 4.
Just to confirm a previous comment. I needed to switch my connection to Camera (PTP) mode in addition to enabling Developer options and then selecting USB Debugging from the newly appeared Developer Options.
To enable USB debugging, go to settings, about phone and then at the bottom tap build number seven times. This will enable the developer settings where you can enable USB debugging.
To fix/install Android USB driver on Windows 7/8 32bit/64bit:
Connect your Android-powered device to your computer's USB port.
Right-click on Computer from your desktop or Windows Explorer, and
select Manage.
Select Devices in the left pane.
Locate and expand Other device in the right pane.
Right-click the device name (Nexus 7 / Nexus 5 / Nexus 4) and select Update
Driver Software. This will launch the Hardware Update Wizard.
Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB
Driver is located in <sdk>\extras\google\usb_driver\.)
Click Next to install the driver.
If it still doesn't work try changing from MTP to PTP.
I had the same problem, but I didn't want to change to PTP mode. This is how I fixed it with MTP still enabled.
Uninstalled Google USB Driver from Eclipse in the Android SDK Manager.
Uninstalled the driver from Device Manager - click box for "delete driver from my computer"
Unplugged and re-plugged my phone into the computer.
Windows "improperly" installed drivers for the Nexus 4.
The Nexus 4 was now showing up in My Computer like a drive.
Reinstall Google USB Driver in SDK Manager.
Update Nexus 4 driver in Device Manager.
Everything works.
I had the same problem and none of the above worked, but the following solution worked for me:
On my Nexus 4:
Go to Settings
Choose Developer options (from the end of the list after pressing seven times on "About phone")
Check the "USB debugging" and press OK.
For what it's worth, in my case I was able to fix the problem simply by changing my USB connection mode from Media device (MTP) to Camera (PTP).
I had to resort to a clean install of Windows 7 x64 to fix this issue.
I tried all steps/variants in the other answers. No luck. Device Manager would show my 'Android Device / Android Composite ADB Interface' working properly with the 7.0.0.1 driver from Google, but nothing could get 'adb devices' to show my Nexus 4.
I used USBDeview to uninstall every USB device that had connected to my computer except my keyboard and mouse. No luck.
I enabled 'Show hidden devices' in Device Manager and uninstalled anything related to USB. No luck.
I added Google's vendor ID to adb_usb.ini. No luck. I deleted adb_usb.ini and ran 'android update adb'. No luck.
I brought my Nexus 4 to my brother's apartment to confirm it wasn't faulty. Worked on his machine without a hiccup.
I'm glad the clean install worked, because further troubleshooting was going to require swapping motherboards or buying a MacBook.
Boy, that escalated quickly.
Changing USB mode from MTP to PTP worked for me.
How to do it on Windows 8 (I think, it will work for Windows 7 too)
Open Android SDK Manager and delete Google Usb Driver
Open Control Panel -> Devices Manager -> Find your Nexus -> right click -> delete device
Unplug your device
Open Android SDK Manager and install Google Usb Driver
Connect your device
Open Control Panel -> Devices Manager -> Find your Nexus -> right click -> update drivers -> Manual update -> open android-sdk folder (enable checkbox for subfolders) -> install driver from Google Inc
adb kill-server; adb start-server; adb devices should show your nexus
Do not forget, that Android 4.2 now want you to submit RSA key from your computer, look at your device screen.
To enable developers options on Android 4.2: Open Settings -> About phone -> Tap on Build Number 7 times.
Just to add to the above posts for anybody struggling to get their Nexus 4 recognized by Eclipse - ADT. In the past the device was recognized by Eclipse ADT without any issues!
I ran into the same problems as the original question. Every approach I tried wouldn't work...
Toggling "USB debug" selection
Toggling "Allow 3rd party" apps selection
Allowing Mock locations
Reinstalling driver
Restarting adb.exe
Simple solution in the end
Go to Settings -> Storage -> USB Computer Condition (Menu option from Storage Screen)
Change from Media Device (MTP) to Camera (PTP)
You need to install USB drivers only if you use Windows (If you're using MAC/Linux, most likely it will work fine without any driver installations)
in the following link they describe how to do it:
http://developer.android.com/tools/extras/oem-usb.html
In short:
Connect your Android-powered device to your computer's USB port.
Right-click on Computer from your desktop or Windows Explorer, and select Manage.
Select Devices in the left pane.
Locate and expand Other device in the right pane.
Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch 6. the Hardware Update Wizard.
Select Browse my computer for driver software and click Next.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in \extras\google\usb_driver.)
Click Next to install the driver.
My symptoms were the composite device (this contains all of the actual USB devices such as the ADB interface, camera, etc) was not being installed. This has a hardware id of:
USB\VID_18D1&PID_4EE6&REV_0228
USB\VID_18D1&PID_4EE6
The composite device's children will have &MI_## after them. If you see those, then this is not the same issue.
I resolved this by coping usb.inf to %windir%\inf from a virtual machine of Windows 7. The hardware detected and installed fine after.
I have 2 Nexus 4 devices. One was connecting to ADB without any problems, the second one never showed up when I used the adb devices command. An additional symptom was, that the second phone did not show up as a portable device in Windows Explorer when the phone was set to Media mode.
At some point I found that a temporary solution for the second Nexus was to switch it to PTP mode. Then it was found by the adb devices command. The weired thing was that the first phone worked in both modes all the time!
Finally I found this solution that now allows me to connect both phones in both modes:
set USB mode of the phone to MTP (Media)
Using PC device manager uninstall the device ->Android Device ->Android ADB Interface
Make sure to check the box "Delete the driver software"!
then set the USB mode of the phone to PTP (Camera)
Using PC device manager uninstall the device ->Portable Devies ->Nexus 4
Then unplug the USB and plug it back in (ensuring that its set to MTP (Media) and I found that the device was correctly registered in Device manager as a ->Portable Devies ->Nexus 4
Solution found at: http://forum.xda-developers.com/showthread.php?p=34910298#post34910298
If you have a similar problem to connect your Nexus to ADB then I recommend to first switch it to PTP mode. If your problem vanishes with that step, I recommend to go through the additional steps listed above as MTP will probably be the mode you will want to set your phone to most of the time.
Follow Google's instructions for this, OEM USB Drivers.
In case none of the answers work perhaps the following clarifications will help. I followed the top answer and tried to load the program with ADB from the command line to reduce the possible complications and this did not work.
Once enabling PTP mode the ADB devices command would find my Nexus 4, but I could not push to it. I had to use Eclipse and in order for the dialog to display to accept the RSA key described below.
Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key.
On Windows 7, with Samsung Nexus S, it showed nothing in Device Manager, the adb devices command showed no devices, but when plugged in device said USB debugging was on and connected.
I used Andrea's Feb 2 answer to install the Google USB driver, which created the /gooogle/usb_driver directory and used RobertNovelo's Mar 7 answer to go to the link and follow the instructions. The device showed up in Device Manager under 'other'. I right clicked on it and selected update driver, and now it shows up in Device Manager under 'Android device', and now command line adb devices lists it.
I had a similar problem, and none of the previous solutions worked for me, and I've just solved it by myself (after a few hours of frustration), so I'm going to share my solution.
My computer suddenly stopped recognizing any Android device I've plugged in after it installed Android Composite ADB Interface for my Nexus 4. I was not able to uninstall the driver, because any attempt to do so by Device Manager was unsuccessful (Device Manager stopped responding every time).
So I've solved it this way:
Switch Windows into safe mode
Uninstall Android Composite ADB Interface
Install old SAMSUNG Android ADB Interface
Switch Windows into normal mode
Plug-in Android device (Nexus 4 in my case)
Windows recognized the device as Nexus 4
Install driver from android-sdk/extras/google folder
Everything works again! :)
I have a way to fix your problem:
Download Nexus Root Toolkit v2.0.4: http://www.wugfresh.com/nrt/
Install and select your diver and choose the Google API. For example, I chose Nexus 4 and selected Google API 4.4.4
Click "full driver installation guide..." and click step 3 tab. Choose the Google drivers.
My Windows 7 installation was not finding a driver at all. The xda-forums post has the right folder to tell Windows where the drivers are -- {SDK directory}/extras/google/usb-driver.
If you don't have the extras/Google folder + Tim Bellis, go to the SDK Manager in your IDE and look for the Google USB driver in the Extras category, and install it. I cannot tell you how to do this in Eclipse, but if you have IntelliJ IDEA, it's near the bottom of the list, checkmark it and click "Install packages".
(Windows 7) My solution to this was to find the device in Device Manager, uninstall the existing driver and install a new one from the android folder in your user account using the include subdirectories option.
All the best.
Some of you may have experienced this issue. If you don't find the USB driver (like me, I downloaded a bundle of Eclipse and the Android SDK), go to <sdk>/SDK Manager. Open it and select USB Driver from the options to install and you are ready. I had to do the PTP mode too.
If you have problems to install the ADB driver under Windows 8.1, try this solution: ADB Driver and Windows 8.1
For me, it was Nexus 4 and Windows 7. I reinstalled the drivers, changed to PTP - basically went through everything.
Clicking the tab that said MainActivity.java rather than activity_main.xml in Eclipse fixed it for me.
My solution is very silly. I had tried all the solutions above and wasted so many hours. Then I found out the solution when I browsed developer options. I didn't check mark the "USB debugging" option. The silly me assumed turns on developer options mean turns on USB debugging, but I was wrong.
It was a driver missing problem with me. I had enabled the USB debugging, tried changing the USB cable, tried reinstalling the Google USB drivers, but nothing came to my rescue.
Then ultimately I downloaded the device drivers as suggested here.
To make sure whether you have a device driver problem, go to:
Computer->right click
Manage
Device Manager
And see if you have your Nexus shown as an "Android device" or as a device in "Others".
If it shows in "Others", your problem should be resolved by downloading & extracting this and then following these steps:
Right click on your device after finding it in Device Manager as per the above mentioned three steps.
Say Update driver software.
Say Browse My computer for driver software
Pinpoint it to the location where you had downloaded the drivers from the above link.
Finally, your device will show up as follows:
As soon as you do this, a popup will show up on your device asking for permission to debug. Once you accept, you are ready!
I'm trying to run my applications on OMEGA T107 tablet. But adb doesn't see my device. I tried almost everything.
Some of these answers are pretty old, so maybe it's changed in recent times, but I had similar issues and I solved it by:
Loading the USB drivers for the device - Samsung S6
Enable Developer tools on the phone.
On the device, go to Settings - Applications - Development - Check USB Debugging
Reboot O/S (Windows 7 - 64bit)
Open Visual Studio
I think it was step 3 that had me stumped for a while. I'd enabled developer tools, but I didn't specifically enable the "USB Debugging" but.
I tried all the ways listed on the web for a whole day, but I didn't get any solutions. Then, I followed a link and in just two minutes my problem was solved!
By the way, it's for Windows users!
Find out the vendor id of the device from device manager.
To do this, connect the OTG port to the USB port of your computer.
Go to Start Menu and right-click on “My Computer” and chose “Properties”.
Select the “Devices” option which will open “Device Manager”.
Select your device (mostly in USB devices or Other devices) and right-click and choose “Properties”.
Choose the “Details” tab and select “Hardware Ids” from the property dropdown, you can see the hardware id, in my case it was x2207 .
Open android_winusb.inf and add these lines:
;<Device name> in our case I gave MK808
%SingleAdbInterface% = USB_INSTALL, USB\VID_2207&PID_0010&MI_01
%CompositeAdbInterface% = USB_INSTALL, USB\VID_2207&PID_0010&REV_0222&MI_01
Open C:\Users\.android\adb_usb.ini and add the following entry
0x<device id> .. in our case it is 0x2207
Restart ADB by
adb kill-server
adb start-server
Now ADB should recognize the device.
I had same issue, none of the solutions worked for me.
Open Settings Menu -> Developer Options -> USB Debugging should be on
Android 11
Settings -> System -> Developer options -> USB debugging
The normal way to fix this is indeed to restart the adb server :
adb kill-server
adb start-server
then
adb devices -l
should list connected devices
But it possible that it doesnt fix the problem. It appends to me.
I had to disable/enable the debug mode on the device, and then restart adb server.
On Windows it is most probably that the device drivers are not installed properly.
First, install Google USB Driver from Android SDK Manager.
Then, go to Start, right-click on My Computer, select Properties and go to Device Manager on the left. Locate you device under Other Devices (Unknown devices, USB Devices). Right-click on it and select Properties. Navigate to Driver tab. Select Update Driver and then Browse my computer for driver software. Choose %ANDROID_SDK_HOME%\extras\google\usb_driver directory. Windows should find and install drivers there. Then run adb kill-server. Next time you do adb devices the device should be in the list.
Not all USB cables can transfer data. Try using a different USB cable if your device is charging, but doesn't establish a connection to your machine.

What operating system are you on? If you running Windows you will want to make sure you have the drivers. You should also make sure that your Android SDK Manager is not only installed, but it also contains some additional things for different devices. Not sure if yours is in there or not.
Make sure that your phone has debugging enabled. I found myself having to run
adb kill-server
adb devices
often.
On windows, you will need to install drivers for the device for adb to recognize it. To see if the drivers are installed, check the device manager. If there is any "unrecognized device" in the device manager, the drivers are not installed. You can usually get the adb drivers from the manufacturers.
For Windows 8 64 bit with a Nexus 10 device, this worked for me:
https://github.com/koush/UniversalAdbDriver
It has a link at the bottom to this:
http://download.clockworkmod.com/test/UniversalAdbDriverSetup.msi
It worked for me in my Astro Tab A737
Download and install PdaNet+ from http://pdanet.co/a/ in your computer.
follow all steps in the wizard while installing .Once the drivers are installed Android studio should recognize the tablet.
Also, make sure the device is in PTP mode.
Uninstalling all old "Android ADB Interface" drivers that were installed previously and then installing the new one worked for me.
Debugging needs to be enabled on the target device in order for adb to see it.
Intel has a peach of an article on this. It's all the same driver. It's just a Device ID mismatch in the Inf file which can be edited, or Windows forced to Install the driver we point it to. Intel's article is very thorough and takes care of every hurdle you come across. The link - https://software.intel.com/en-us/xdk/docs/installing-android-debug-bridge-adb-usb-driver-on-windows
Keep in mind while you connecting device Android propose to select one of possible connection options.
In my case:
File transfer
Power charging
Media
Not all types of connection will work with ADB. In my case need to select Power charging to be able to connect to ADB
Go to Device Manager
Right-click Android Composite ADB Interface
Uninstall devices
Right-click your LocalPC then select Scan for hardware changes
Your device should be enabled
Open Command Prompt
adb kill-server
adb start-server
adb devices
I want to run my Android project on a device.
My device is not detected in Eclipse when I connect it with a USB cable.
I restarted Eclipse and I have checked that USB debugging is on, on the device.
Can anybody tell me what the problem is and how to resolve it?
Before starting, Make sure that USB DEBUGGING IS ENABLED in your phone settings !!!
1) BASIC STEP - Plug in device via USB, then go to device page in Android developers blog. There you can find necessary information regarding adding USB vendor ids. Add your device specific ids, and restart eclipse if needed.
2)If you were able to see the device connected(using command: 'adb devices'
) earlier, but not anymore, then just try restarting ADB. (you can use the commands: 'adb kill-server' followed by 'adb start-server'. adb commands need to be executed from platform tools folder in the Android SDK, if you havent exported it).
3)If neither of them works out and you are on windows machine,
then check the installed usb drivers are correct. If not install proper drivers
Please find more information on how to install/update drivers in http://developer.android.com/tools/extras/oem-usb.html
If this also is not working, try installing Universal ADB windows driver https://plus.google.com/103583939320326217147/posts/BQ5iYJEaaEH
4)You may also try increasing the timeout time
Go to preferences-> android->DDMS in eclipse, then try increasing 'ADB connection timeout(ms)' value
Update based on newer answers:
5)Run > Run Configurations > Target. Please make sure, the option "Always prompt to pick device" is enabled.
Special case: Windows 8 and Nexus 10 (from this question: ADB No Devices Found)
Windows 8 wouldn't recognize my Nexus 10 device. Fixed by Setting the
transfer mode to Camera (PTP) through the settings dialogue on the
device.
Settings > Storage > Menu > USB Computer connection to "Camera (PTP)"
I solve this problem by updating PC portable device drivers:
Go to : Settings -> Applications -> Development to enable USB debugging
Plug in device USB
Desktop "My Computer" right click -> "Manager"
Choose "Device Manager"
Portable Device
right click on your device -> "Update Driver software" -> Search automatically (wait about 3-5min, )
Done
Restarting the adb server, Eclipse, and device did the trick for me.
C:\Android\android-sdk\platform-tools>adb kill-server
C:\Android\android-sdk\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
I had the same problem as mentioned on this question.
I had similar problem, drivers was okey, but Eclipse did show me the device in Run > Run Configurations > Target tab. But I checked the option "Always prompt to pick device". And then running the application from Eclipse the prompt window finally showed my device.
After a long and frustrating search, finally I made my Micromax Funbook p362 to connect with eclipse and made it to suit for development.
*Installed Moborobo (All in one Android smart phone management tool).
*Perform stop -server / start -server using ADB.
*Reboot the device.
*Restart the eclipse.
*Device got detected.(Eclipse - list of adb devices)
In addition to the steps provided by #asfsafgsf (above), make sure to re-enable your phone's developer modes/functions. For my Motorola Atrix:
settings>applications>Unknown Sources: allow 3rd party apps
settings>applications>Development: to enable USB debugging, mock locations, and disable phone sleep
A note on developer modes
USB Debugging is the main mode you will need for running apps through eclipse when your phone is connected via usb (obviously). Disable phone sleep is also handy for self-explanatory reasons.
Allowing 3rd party app sources allows you to beta test your app on a larger-scale. With this, you can host your own apk and instruct your beta-testers to download it (prior to releasing it to the Google Play storefront). More specifically, 3rd party support allows the installation of android package files that don't contain a google approved signature (required for play store hosting). With 3rd party apps enabled, a handset will be able to run packages regardless of their source. You should also be able to receive an APK via bluetooth and install it in this mode.
You can also list all currently connected devices by running the following command:
adb devices
Go to http://developer.android.com/tools/extras/oem-usb.html#InstallingDriver and follow the steps on the android website but on browsing for the USB folder don't use the directory specified -> ((sdk)\extras\google\usb_driver). (sdk) just means your sdk location.
Your phone should have the correct driver and it can be accessed when you plug it in and go to the CD Driver in My Computer, in my case it's G:\drivers\adb_driver. Use this directory instead and it should work. (It may be differ with devices).
One possible reason is to check Android SDK Manager and install Google USB Driver in Extras folder if you have not installed it.
Following the steps here: http://developer.android.com/sdk/oem-usb.html#InstallingDriver allowed Eclipse to display the device.
Do following steps to detect your device in eclipse : -
On Mobile Side:- For Connect USB sync, your Android device needs to have USB Debugging enabled.
To enable Android USB Debugging Mode do following steps :-
Android 2.x - 3.x devices:
Go to Settings > Application > Development > USB Debugging.
Android 4.x devices:
Go to Settings > Developer Options > USB Debugging.
For devices running Android 4.2.2 or later, you may need to unlock Developer Options before it is available within the Menu:
Go to Android home screen.
Pull down the notification bar.
Tap "Settings"
Tap "About Device"
Tap on the "Build Number" button about 7 times.
Developer Mode should now be unlocked and available in Settings >
More > Developer Options or in Settings > Developer Options
On PC side
Connect your device to the PC with USB cable.
Download Google USB Driver
Extract/Unzip “latest_usb_driver_windows.zip” file on your computer
(using 7-zip free software, preferably)
Open device manager on your PC
Windows 7 & 8 users → search for
Device Manager from Start (or Start screen) and click to open.
Windows XP users → Google it
You will see list of all devices attached to your computer in the
device manager. Just find your device (it’ll most probably
be in the Other devices list with a yellow exclamation mark by the
name of ADB devices), then Right-click on it and select Update
Driver Software.
Select “Browse my computer for driver software” in the next window
Now click the “Browse…” button and select the “usb_driver” folder
that we extracted in Step 3 from “latest_usb_driver_windows.zip”
file.
Do NOT select the zip file, select the folder where the
contents of the zip file are extracted. And keep the Include
subfolders box checked
During the installation (as a security check) Windows may ask your
permission to install the drivers, click “Install”
Once the installation is complete you’ll see a refreshed list of
devices on the Device manager screen showing your phone’s driver
installed successfully.
Now in eclipse do following steps to install your app in your device:-
Go to Run > Run Configurations > Target tab.
Check option "Always prompt to pick device". And then running the
application from Eclipse,the prompt window finally showed
your device.
Please check whether your device is shown in the Eclipse device tab in Window > Open Perspective. If its not shown there then you need to install drivers for the the device. Once the device is visible in the Devices tab then change the launch settings for manual target. Once you launch your app then it will allow you to choose from the real device or the virtual devices
If you have the following problem
Then you can so following to fix it
Note : You should enable USB debugging on your android device(It will be in developer option in System settings)
I had this problem. With my galaxy S2. So came here for advice, but couldn't find anything specific. Then I found this 'Kies' software on the Samsung site, under the section for my exact model of phone, under downloads, after clicking software.
It installed the right USB drivers as part of the process of installing Kies and so my phone instantly then became visible on eclipse.
The Kies version for Galaxy S2 (GT I1900) = http://www.samsung.com/uk/support/model/GT-I9100LKAXEU-downloads#
There are other versions of Kies for other android models of course.
(new) device not showing, Check List:
Developer Option ON
USB debugging ON
Try changing to USB Storage/MTP/PTP
if it installs Window driver and fails, there's your problem (verify in Windows Device Manager) fix it.
ok this is an old thread -
but I spent nearly two days and did not get anywhere
Here is what solved my problem
I had USB debugging enabled ( finding developer options itself was a pain - I think the 7 times tap from google is childish and just plain stupid - rant over )
However HTC syn manager , eclipse ADT and windows computer management were all unable to identify my device
My problem was my phone was set to ONLY USB Charge - this was the problem
In 'USB Computer connection' >> Choose the option USB Storage
Once you do this - PC will install drivers and your device will get detected by Eclipse as well as in 'Computer Management' under ''Android USB devices '
Now I still dont know a way to access ''USB Computer connection' but at that time I did get the option to change and t worked
For those ( like me earlier ) who dont know how to identify if 'Computer Management' shows their device look for 'Android USB devices '
If its present - then your device is being detected by your PC
Hope this helps some others

On a kitkat Google Nexus 7, I tired everything here, and did not succeed. The device did previously connect properly to this computer.
Then I hit settings - developer-options - Revoke USB debugging authorisations
and confirmed that I really did want to revoke them.
I unplugged and plugged the USB. The tablet beeped and asked if wanted to authorise the computer for debugging. I said "Yes" and everything worked again.
For me the problem is with Defective USB Cable. I have tried those above all answers. Nothing gives me any fix. But finally i came to know the problem is because of my usb cable while changing the usb cable. While connecting through the usb cable the phone is charging but the drivers are not installed. Some usb cable don't have the option for that. So while buying check it and buy.
Best approach is install PDA net(software) on both system as well as in android device. This software automatically installs global driver for all phones, provides easy connectivity to android device.

Here is my checklist in windows (not the device itself) when my device is not shown:
Make sure "USB debugging is turned in setting>Developer options.
Check status bar on your device. It tells you if your phone is connected as Media Device (MTP) or Send images (PTP). My device is only listed when PTP is selected.
Turn of windows firewall.
Turn of any proxy programs ran on whole windows ports.
And finally stop adb.exe from windows task manager and wait some seconds to restart automatically.
