ADB not responding in android studio

Question

The dialog has 3 options: Wait more, Restart and Cancel. But all of them gives me the same result, ie a message Waiting for ADB appears and I can't do anything with Android Studio.

I have to kill the program using windows task manager! I'm using windows 7.

I tried some steps like rebuild project and clean project but it didn't work correctly....I also try kill the adb.exe in Task manager ..but it not show in the Task manager sometimes.

Can anyone help me on this?

the main problem is adb.exe not found in Task manager..

Answer 1

Open command prompt and type in the below command

adb kill-server

then start server using the below command

adb start-server

This could remove any potential "waiting for adb" message if your adb server is not started correctly

Note: you may want to have adb in path variable
