i\'m using android studio 2.1.1 in ubuntu 14.04.Now my question is,i want to run the program through my phone without emulator. so i chose the target as usb dev

Answer 1

I had this problem after upgrading from Android Studio 2.3 to 3.0. As simple as it sounds, I actually just restarted my phone to fix it.

My guess is that the adb server on the phone somehow cached something from the previous installation of android studio, maybe a connection object or something, and by restarting the adb server it resolved the issue.

I hope this helps someone.

Answer 2

try with

sudo adb kill-server
sudo devices

or

echo $ANDROID_HOME
sudo $ANDROID_HOME/platform-tools/adb kill-server 
sudo $ANDROID_HOME/platform-tools/adb devices

1. Set up a device for development https://developer.android.com/studio/run/device.html#setting-up

2. Enable developer options and debugging https://developer.android.com/studio/debug/dev-options.html#enable

Optional

3. How to enable Developer options and USB debugging
   • Open Settings menu on Home screen.
   • Scroll to About Tablet and tap it.
   • Click on Build number for seven times until a pop-up message says “You are now a developer!”

Answer 4

If you are using 32-bit ubuntu (my case) then it is most likely that Android Studio has downloaded 64-bit version of adb and fastboot inside your sdk/platform-tools folder. I think you already have installed adb (and fastboot). If you haven't then run these commands in terminal:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb android-tools-fastboot

This will install 32-bit version of adb and fastboot. Now just replace the 64-bit adb and fastboot executable files in sdk/platform-tools with the installed 32-bit versions:

cp /usr/bin/adb <path-to-your-adt-sdk-package>/sdk/platform-tools/adb
cp /usr/bin/fastboot <path-to-your-adt-sdk-package>/sdk/platformtools/fastboot

Now your android studio should be able to run your App in your device.

1. If suppose the android device is not getting connected by android studio then download "PDANet+"(for all android devices).

2. Or also you can do these following steps:

   • Go to Run tab on toolbar of android studio.
   • Then click on edit configuration
   • In General tab there will "Deployment Target Option" click on "Target" and choose "Open select deployment target dialog" and uncheck the checkbox from below.
   • And at last click OK. Finish.

trick that works for me when target device not found:

• click the "attach debugger to android process" button. (that will enable adb integration for you)

• click the run button
