android studio doesn't detect my device on my ubuntu laptop

Question

I am trying to run an app from Android Studio on my Ubuntu laptop.

I have enabled USB debugging, but it is still not working.

When I press run

Answer 1

Make sure you have adb installed in your ubuntu system. If not then type -

sudo apt-get install adb

Provide your system password and press 'Y' asked during installation process.

Then disconnect your device through USB and then reconnect it. You will have to grant permission for debugging which prompts on your device just after reconnecting.

Answer 2

Try to revoke USB debugging authorizations and then connect your device, it should show permission prompt for authorization.

go to

settings -> developer options -> revoke USB debugging authorizations.

Answer 3

I tried restarting adb using root priviledges and it worked for me. Use these commands in the terminal:

sudo adb kill-server
sudo adb start-server

Hope it works for you too...

Answer 4

1. if you are doing it first time in Ubuntu Linux, then Use sudo apt-get install to install the adb package. This gives you a community-maintained default set of udev rules for all Android devices.

2. or, use sudo adb kill-server sudo adb start-server and check using sudo adb devices

3. you can also check uncheck the usb debugging option, in your developer option in the phone.

Answer 5

For my situation with Ubuntu 16.04, with my device properly connected via USB, confirmed by lsusb

The solution is let the Studio aware of the Android/Sdk folder by defining

export ANDROID_HOME=<the Android/Sdk folder>

in ~/.bashrc

(I have installed the SDK at a custom location)

Then start a new shell, from there re-start the studio, then it works.

If the problem is only on Android Studio and not in your OS you can solve with that.

So first check if adb recognize any devices with:

$ adb devices

If yes, open Android Studio and follow these steps:

1. Go to Run > Edit Configurations...
2. Under Deployment Target Options select Show Device Chooser Dialog from the drop-down-list
