I am trying to run an app that I have built on my phone. I have enabled USB-debugging mode on my LG G3, but my Linux Machine and Android Studio is saying that there are no connected devices.
How do I fix this? Have I forgotten something important?
I had the same connection problem.
Switching to "Send Images (PTP)" solved it for me.
I had similar problem with my Xperia S.
1) I installed android adb tools on Ubuntu. (Using: sudo apt-get install android-tools-adb android-tools-fastboot)
2) Selected MTP mode on my Xperia S. Disabled debugging. Disconnected the phone from system.
3) Enabled USB debugging, connected the phone again and tried the command "adb devices" from ubuntu terminal.
It then started the adb daemon and listed my device.
Once the device was listed there, I started the android studio again, and my phone was listed there.

Hope it helps..
CD to your sdk platform-tools folder
Check if adb sees your device
./adb devices
If it displays 'List of devices attached' and a blank line below, then restart adb as follows:
./adb kill-server ./adb start-server
then re-run ./adb devices and see if it picks up the device, eg as follows:
List of devices attached xxxxxxxxxxx
There is a well-written and detailed step-by-step guide for connecting a phone with Android Studio when running Linux here:
http://esausilva.com/2010/05/13/setting-up-adbusb-drivers-for-android-devices-in-linux-ubuntu/
Changing in the USB Options on the phone to "Send Images (PTP)" worked to me as well (on a LG phone). Must be something with LG phones, because with other Android phones this wasn't needed.
After taking a few hours, I just solved a similar problem minutes ago with LG G3 on WINDOWS.
Maybe my experience can help you.
Firstly, do NOT enable USB debugging.
Secondly, install the OFFICIAL USB driver from LG (I have no idea whether this is available on Ubuntu). Please make sure the driver works normally by some LG software. BTW, I don't think LG is good at software.
Thirdly, enable USB debugging and go.
Problem:
Asus Nexus 7 not recognized by adb when correctly installed and connected
Setup:
Asus Nexus 7 tablet
Windows 7 64 bit OS
Steps taken:
Installed 64 bit Java JDK (http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html)
Installed Android SDK (http://developer.android.com/sdk/index.html)
Installed Google USB driver (http://developer.android.com/tools/extras/oem-usb.html)
Set tablet to USB debugging mode
In the Windows Device Manager, the Nexus is recognized as an Android Device via Android Composite ADB Interface. The device status indicates it is connected and working properly, running driver version 7.0.0.1 (8/27/12 update) from Google.
However, when I run adb devices at the command prompt (in the sdk/platform-tools directory), the Nexus does not come up as an attached device - the list is empty.
Does anyone have any insight on what the problem might be? I have tried uninstalling and reinstalling all drivers, restarting the computer each time. I have tried a variety of usb ports and cables, as well as switching between MTP and PTP connections with no success.
Hey I found a solution to this via mkh at
https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k
Try this (as quoted from the above source)
When the Nexus 7 is plugged in there is a persistent notification that
indicates "CONNECT AS / Media Device (MTP)". In this state adb devices
will not show the Nexus. Not exactly obvious why, but I you select the
second option "Camera (PTP)" the device is available for debugging.
This choice is persistent, and I'm guessing that with a band new
device it will connect as MTP until told otherwise
An important note about Nexus 7: There is no option for USB debugging readily available in the device Settings for 4.2.
http://forum.xda-developers.com/showthread.php?t=1989777
"Open Settings, then go to phone details (where u can see kernel, Android-version etc) then just tap your Build number 'JOP40C' 7 times!"
This sounds ludicrous, but after I did this, the developer options unlocked and I was able to see my nexus 7 in Eclipse (mac, Mountain Lion) for debugging.
In my case when I got an empty list using "adb devices" I found that the device manager showed the Nexus 7 tablet under 'other devices' with that dreaded yellow exclamation point indicating that the driver was not installed correctly. Why Windows recognized part of the tablet file system, I don't know. In any case I manually updated the driver to the google usb driver in android-sdks\extras\google.
Then adb gave me the following:
C:\Users\Brian\android-sdks\platform-tools>adb devices
List of devices attached
015d25785b601611 device
instead of a blank. I hope this doesn't mess anything else up but I can now talk to the device.
Had the same issue, Windows 7 32-bit; visited the site that Graham linked in his answer but wasn't happy running PTP (though it did work). Following the steps on another post belonging to the same thread sorted it (I can now connect as MTP); again, a direct quote from https://groups.google.com/forum/?fromgroups=#!topic/android-developers/0-RzE0v-G3k (thanks sfoucher!):
uninstall the driver in the device manager with option "delete the driver software for this device"
reconnect the Nexus tablet
let windows install a default driver which will be inadequate
uninstall again the device in the device manager with the option "delete the driver software for this device"
let windows try to find the driver, this process will fail
go back to the device manager and right click the failed device and update driver
choose the driver location in the android sdk directory (android/extra/google/usb_driver)
I should add that after step 5 I had Nexus 7 listed under Portable devices looking OK but had another Nexus 7 entry under Other Devices to which I applied the driver. My Nexus 7 now appears OK in ADB and Eclipse. In device manager I have Nexus 7 under Portable Devices and Android Composite ADB Interface under Android Device.
I too had the same issue on windows 7 64 bit.
Following thing solved my problem.
Connect the Nexus 7 and tap on Settings-About Tablet-Build version 7 times.!
This will install basic driver for windows
Now, tap on connected as media device(MTP) icon, but you will need to change it as Camera device then
Go to device manager on windows, select Nexus 7 and then update the drivers using the driver avaliable on this link http://developer.android.com/sdk/win-usb.html - This will install a driver ( You can use it with this one)
Now tap on Connected as Camera device and change it to media device - This will install one more driver and you are ready to go.!
i was having the same problem and my solution was to download the device driver from Asus. Below is the link.
http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2
That's how I solved this issue with a different device.
Download the drivers, unzip in a folder https://developer.android.com/sdk/win-usb.html#top
With your tablet plugged, go to System -> Device admin -> Android Device -> Properties -> Details -> Hardware ID
You'll find something like USB/VID_XXXX&PID_YYYY, we will need those XXXX and YYYY later.
Go to the folder you put your drivers and edit the file android_winusb.inf manually.
Add this:
;MY PHONE
%SingleBootLoaderInterface% = USB_Install, USB\VID_XXXX&PID_YYYY
%CompositeAdbInterface% = USB_Install, USB\VID_XXXX&PID_YYYY&MI_01
Save the file
Go back to device manager and try to update the driver with this one. (Driver -> Update driver -> Search in my computer -> Choose from a list -> Use disk).
That worked for me on a Quechua Phone.
What worked for me is downloading the USB driver from the ASUS website:
http://support.asus.com/Download.aspx?SLanguage=en&m=Nexus+7&p=28&s=2
(you have to select the OS, which sometimes doesn't work, e.g. on the link Google returns when searching for "nexus 7 driver"). In that case, click on "Drivers and Download" and search for "Nexus 7". That gets me a page with a working OS selection.
I am using Windows 8 and the only thing that worked for me was the Nexus Root Toolkit 1.6.3 where I done the Full driver configuration Guide ... but I didn't follow the instructions there I went to step 2 and only installed the Signed drivers.
http://forum.xda-developers.com/showthread.php?t=1766475
I had the same problem. For me the newer version of adb is required to connect to the Nexus 7 i.e. to have the Nexus 7 ask me to "Allow USB debugging?"
In short:
Android Debug Bridge version 1.0.31 - Works
Android Debug Bridge version 1.0.29 - Does not work
Download the latest android usb drivers from
http://developer.android.com/sdk/win-usb.html#top
And then manually install these driver using Device Manager. Hope it helps!
I had faced two issues:
Nexus 7 not visible to eclipse/adb when connected over usb on windows 7 64-bit using latest Jelly Bean sdk
It was not showing in the 'My Computer' >> 'Portable Devices' list.
Ultimately, I found that it is an issue with the driver. Steps to resolve the issue - Open Device Manager, Uninstall the current driver (along with delete option set to yes), disconnect the device, reconnect it again, let windows install the default driver it wants, and then installed the google sdk driver again. It worked this time.
Above tells me that there is some issue with default driver and therefore, you have to delete it and re-install it. Now, it is visible in eclipse/adb and also showing in 'My Computer' also.

Install Google usb driver from SDK Manager.
Later go to Device Manager, under "Other Devices" you'll see "Nexus" with the yellow exclamation mark. Right Click>Update Drivers>Let me choose>Let me pick from device drivers on my computer. Select android-sdk folder and click ok.
This solved my problem
Another option is if windows updates are turned totally off on your PC. In this case even if you download the USB driver & try update it manually as described above it will not work. The only way in this case is enabling windows updating drivers automatically. Once you enabled this, remove the non-working driver from device manager & connect you tablet to the PC via USB cable. The drivers will be automatically downloaded & installed by Windows.
This way worked on my Windows 7 PC.
After downloading the USB driver using the SDK manager, you can speed up the search for the new driver by telling Windows to look in the C:\Users\jdaehn\AppData\Local\Android\android-studio\sdk\extras\ folder (and sub-folders, in my case the drivers were in C:\Users\jdaehn\AppData\Local\Android\android-studio\sdk\extras\google\usb_driver)

I was developing an android application from Eclipse, connecting my Acer ICONIATAB A 500, with Android 3.0.1. And I did not have any problem.
Now I'm trying to developing the same application on Acer ICONIATAB A 501, with Android 3.2
and my ADB can't find the new device, while Windows can find it! I set in my tablet Debug USB option active, and I installed the appropriate driver on Windows.
I installed even the last Google USB driver (Rev. 7)
I tried to list the device find form adb with command
adb devices
from command line, but List of devices attached is empty.
What can i do?
execute these line
adb kill-server
adb start-server
if it is mobile device check that in settings, developers options , debugging mode is checked or not
You need to install LGUnitedMobileDriver package from the LG website, even though Windows 7 automatically installed USB drivers for the phone.
Try to update your Android-SDK on your computer (in Eclipse or whatever IDE you are using), this helped me solve a similar Problem.
Eclipse DDMS Not recognising my Nexus (samsung)phone .I had install usb drivers externally as well as from device manager. also had conneceted device by usb cable in debug mode still it is not able to recognise in DDMS.please help what to do .Thanks In Advance.
I had a similar problem with another phone using Win7 x64. You should check first if all drivers are installed correctly.
Control Panel -> Device Management and check if there's something wrong.
If you use Win7 x64 try to reboot your system and start Window without using Driver signature.
Hope this help you

Drivers got installed successfully and still device is not recognized by DDMS? Here is what worked for me. https://stackoverflow.com/a/32519507/1567675
After developing and testing for months my android application both on the emulator and on a phone, I suddenly can not connect any more to the phone in one of the two PCs I use for development.
One PCs runs Windows XP 32bits. Here everything is ok. But my main development machine is a Windows 7 32bits: Both of them run Eclipse Galileo. I can not get connected to the Samsung Galaxy S GT-I9000T phone from there. Two Sundays ago I updated my application last version to the phone. Went on vacations. After returning I upgraded the Samsung Kies suite to the new version 2. It is supposed it installs USB drivers for Windows. I also upgraded to Android SDK 9 and ADT 9 but I'm not sure it was after the problem appeared. Then I realized can not connect to the phone. My first suspect was Samsung Kies. But I made all these intallations on the xp PC and the connection works OK. Then I returned to the Windows 7. There is another driver called "USB Driver for Windows" which I have installed from Android's SDK "SDK and AVD Manager"/"Available Components"/"Android Repository" I tried to reinstall it. I deleted the package despite the warning it can not be undone. Then I tried to find it on the "Available Packages" but it was no more there.
I reinstaled Samsung Kies, Eclipse, Android SDK but the problem remains the same:
Another fact: with USB debugging active, Samsung Kies can not connect to the phone. It detects something is connected but it stays forever trying to connect.But it occurs also on the XP machine.
In summary:
I can not get listed the "USB Driver for Windows" in the "SDK and AVD Manager"/"Available Components" for installation, even after reinstalling all the development environment
I can not get the development environment to connect to the phone for debugging.
How to fix this?
Any hint is welcomed.
Thanks in advance.

I finally found the origin of the problem. I hope it will be useful to someone else.
Device Manager showed "ADB Interface" / "SAMSUNG Android Composite ADB Interface" with a warning sign. The device was not running 'cause some inconsistencies in the registry.
I deleted both the "ADB Interface" / "SAMSUNG Android Composite ADB Interface" and "Universal Serial Bus Controllers" / "SAMSUNG Android USB Composite Device" and reinstalled them from Windows Update. This time I didn't used Samsung Kies Tools / Install Driver menu.
Thanks for your time.
