I know this type of question has been asked before but I couldn't solve my problem with any of the solutions.
My device is not being recognized by my emulator and the the in adb devices List.
I have enabled USB debugging in my phone and tried setting USB devices as my default device in edit configurations but the problem still persists.
I am using windows 8.1 and it doesn't work no matter which android device i connect.
Any help will be highly appreciated.
I have experienced this before. Here is what I have done (for Windows 10 OS). I am not sure whether you have tried this solution before.
Go https://developer.android.com/studio/run/oem-usb and download the OEM driver of your android device
Go to Windows Device Manager. For my case, I found a device, namely "adb" with a warning sign. (something like the following picture)
Click your device -> Driver -> Update Driver -> Browse my computer for driver software. Choose the OEM driver that you have downloaded in (1).
After the update, you should be able to see the device on Android Studio
i'll suggest you to check ur device driver or u can use this link universal ADB driver
& check with the minimal ADB & fast boot, device is recognizing or not.get ADB fastboot from this link
I am setting up a Android development environment on a new Windows 10 laptop. I have done this many times on other machines with other operating systems, but this is the first time with Windows 10. The problem is that Android Studio cannot detect my device (LG Zone 3) after I connect it via USB. Note that I have previously used this device for development on an Arch Linux desktop.
I have downloaded Android Studio and created several AVDs. I can run my app and tests on those just fine. However, my hardware device is not listed in the selection dialog.
Here are some things I have tried:
Check that the USB drivers are installed.
Restart ADB from the Android Monitor window in Android Studio
Restart ADB from the command line with adb kill-server and adb start-server.
Quit Android Studio and restart it.
Unplug the device, turn off USB debugging, and turn it back on.
Plug device into a different USB port.
Switch device connection settings to Charge Only and then back to MTP.
What other trouble-shooting steps can I follow to get my device to work?
Depending of your device you might be required to install the phone specific drivers.
Also, sometimes it helps if you go to phone Developer settings and uncheck/disable USB debugging and enable it again.
There are few ways to resolve this problem.
Case 1. Enable the USB debugging option in your mobile.
Setting > developer > Check "USB Debugging"
Case 2. Change from MTP to PTP.(sometimes vise versa works)
Case 3. If nothing worked then try to Install PdaNet+ in your system. This Actually worked for me.
If it solved your issue then answer this question in the comment section > Which case solved your issue? it will help the coming people who are facing the similar problem.
Try this also
1.Just change your cable & give try again
2.Uncheck "Tools" - "Android" - "Enable ADB Integration".
3.Re-Install Google USB drivers
GOTO - http://developer.android.com/sdk/win-usb.html#top
Download the driver
Reinstall it
In my case, an LG device, I just downloaded drivers from the lg site, and it fixed the problem without having to fiddle with any settings.
LG site: http://www.lg.com/us/support/software-firmware-drivers
In my case, I discovered that my device was paired via Bluetooth to my Windows 10 machine. This was preventing it from being listed as a portable device keeping it hidden from Android Studio so make sure the two are not paired.
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

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 am not able to resolve this simple issue.
I am trying to connect my device to Eclipse via USB cable.
On my PC, I have installed Eclipse and the Android SDK and running the program on the emulator is working fine.
I have downloaded and installed Samsung Kies on my PC. It shows my device if connected via USB to the PC.
But I dont know how to connect the device with the emulator.
Connect means, I want to run the Eclipse code on my device instead of emulator. I am using Samsung Galaxy Ace GT-S5830i. Please help me out to resolve this issue.
Comment is lack of formatting so i add an answer.
Check if your computer had your phone driver. I assume that your use Windows. Open Device Manager
At a command prompt, in the Start Search box, or in the Run box, type the following command: mmc devmgmt.msc
. Other ways : check link
If you find your phone name or ADB Interface so you got driver. Try to restart DDMS or restart your Eclipse.
If you don't find your device or see something Other device with yellow question mark so try to install driver by browsing on your phone to Settings - Developer Options - Enable developer option - Enable USB debugging - Plug your phone to computer. Windows will ask you to install driver.
3, Update Google USB driver in Android SDK Manager (in Eclipse) or search Samsung Galaxy Ace GT-S5830i driver
4.Some weird case i got on some device.
Nexus S: disable Developer option. Restart phone. Enable again. Windows ask to install driver or you will see it in Eclipse.
HTC phone or Samsung : change Connectivity Option on phone to Charge only (Swipe status bar. Check notifications displayed). Some phone set it to some kind of Sync data so Windows can not recognize device.
I think your emulator is in Automatic. You can change that to Manual.
Try this,
Step 1
Go to Run Configuration
You can see three Columns Android,Target and Common.
Step2
Select the Target
Step 3
Choose Always prompt to pick device.Click Ok
Step 4
Now run your project you should see the emulator and your device. Select your device and click ok.
Hope it helps.

Troubleshooting
This all sounds very straightforward, but there are countless quirks and hard-to-diagnose problems that can make connecting a device much more difficult than it sounds. In this section, we'll run through a checklist of things to try when your device isn't registering.
Check that USB Debugging is enabled. This setting can inadvertently (and perhaps even automatically) change when you plug/unplug your device from your machine, or when you reboot your phone.
Check your device while it's connected to your machine. Is it asking you to choose between different modes? Some phones have a 'charge only' mode that can prevent Eclipse from recognizing the device.
Choose a connection type
Make sure you don't have an Android Virtual Device running in the background.
Could there be a problem with the USB cable? If you have a spare cable to hand, plug it in to rule out a fault with the cable itself.
Double-check you're running the correct driver. Even if you are, some devices have all the required software pre-installed (for example, HTC Sync) and downloading drivers from another location can muddy the waters. If this might be the case with your device, try uninstalling the driver from your machine and reinstalling the software from your device's memory.
Does the driver require supporting software? Samsung Kies on Windows requires .Net Framework 3.5 SP1 or above, for example. This is usually installed along with the driver, but there's no guarantee.
Running the Android Debug Monitor tool (monitor.bat) has been known to kickstart Eclipse into recognizing a new device. Connect your device, locate monitor.bat (android-sdks/tools/monitor.bat) and double-click to open. This will open the Android Debug Monitor, a stand-alone debugging tool that lists connected devices.
Android Debug Monitor
A running adb.exe process can interfere with the connection. Close Eclipse, and open the Task Manager by pressing CTRL, Shift and Esc. Find the adb.exe process and kill it. Launch Eclipse and try again.
Check that your 'Project Build Target' is compatible with the Android version on your device. You can check what version of Android your device is running by opening 'Settings' and selecting 'About Phone,' followed by the 'Software information' option if available. If you need a reminder of your project's build target, ensure the project is selected in Eclipse's 'Package Explorer,' open the 'Project' menu and select 'Properties.' If the 'Android' tab isn't selected by default, open it and the Build Target will be displayed.
Have you enabled USB debugging in your device?? You can find it in your device
Settings -> Developer Options -> USB Debugging.
The android app you have created will be a .apk file, generated by eclipse, during a successful Run. Find the .apk file from the eclipse project explorer or by tracing your workspace. Copy the .apk file to your memory card (via USB or a card reader) and install it.
You should also enable the "Unknown Sources" option under "Security" of your Android device.
If you have required options enabled on your phone (USB Debugging and Unknown Sources) you can try do this. On your computer open command console. Using cd navigate to your android sdk installation folder. Go to platform-tools. You should have there adb file. Run this
./adb kill-server
and then
./adb start-server
Then check plugged devices
./adb devices
First, you are not connecting device with emulator. What you want is eclipse to identify your device and use it for development.
Everything about using devices for android development is given in official documentation.
You have to put the phone in 'debug' mode - I don't have the instructions handy (but you can search here or on the android site for the info you need).
Also check for THIS.
Try right clicking the project -->Run As --> Run Configurations then select target and choose always prompt
On your device turn on debug mode
Now try running project
I am assuming you don't mean connecting the device with the emulator but connecting the device to your computer so you can debug it and run applications directly from Eclipse to the device. In which case KIES by Samsung will not help you at all. What you need is the Android USB Drivers provided in the Extras tab in SDK. Sometimes the installation will bug up because you didn't run SDK manager as an administrator so make sure you do that. When all of this is done make sure your device is unconnected to your computer and then reconnect it after the drivers are installed. You should be prompted with a new device installation wizard which you must accept. Additionally, you should have debugging enabled on your device, and as an extra step you can setup launching as a manual configuration but it is not needed.
To enable device debugging
Settings -> Developer Options -> USB Debugging.
For more information visit here
BTW : If the Google USB Drivers don't work you might need to install the specific Samsung drivers which are located here
Goto -> Setting -> Application -> Development -> USB Debugging
Enable it and try.
I know this is a little old, but I was having the same issue. I tried all the options of setting usb debugging (off), disconnecting, restarting phone, usb debugging (on), connecting the phone and it just wouldn't connect.
I ended up installing the latest version of Kies on my machine and added the Unified option at the end of the installer and I then the phone would connect. (Not sure i needed the unified option) but it worked for me.
I tried all the above but it didn't helped me. I did couple of things additionally
Since my mobile device is Android, I unchecked Unified option from Kies installer. This is the crucial thing that helped me solve my problem
I restarted my mobile phone.
Here i saw various question related to "usb debugging" but answers not really helped me . can any one put light on this issue...
Your any help is appreciable
My problem solved after doing this
I updated usb driver :
i followed step written here under WINDOWS XP .
Device manager view
and ...
i reconnected my device to pc(winXP).
enabled usb debugging in device
usb debugging= set true in android manifest
In command prompt...
C:\android-sdk-windows\platform-tools>adb devices
List of devices attached
emulator-5554 device
e4567855.... device
For most android phones you will also need to install custom adb drivers in order to get it to work. Try installing any software suites that came with the phone as these may have the required drivers. Otherwise look on google for the adb drivers for the particular phone.
For the xperia in particular I was unable to get adb to find the phone until it was upgraded to 2.1 so you may need to do this if you are using an older android version.
If you run android at a command prompt it brings up the Android SDK Manager: under "Available Packages expand the Third party Add-Ons option. There looks to be a new Sony-Ericsson driver. Making sure you have that downloaded and then update the driver for your device from the downloaded driver file may solve your problem.
