问题
Since I've upgraded Android Studio to 2.0, I have been not able to debug. It hangs with "waiting for the debugger to attach" on the screen. Do you have any idea why this is happening?
回答1:
This is a common scenario. Restart your Android Studio and reconnect your device.
I was having the same issue, except I was running into it with the Android Emulator. I figured out that if you put your computer to sleep while Android Studio or the emulator are running, that messes up the connection between them. My problem went away after I restarted both, the emulator, and Android Studio.
回答2:
Clearing the Intellij IDEA (Android Studio) .idea directory which contains configuration information worked for me:
- Exit Android Studio
- Navigate to the project you are trying to debug
- Backup any files inside .idea that you modified (if your project checks any of these into VCS)
- Delete .idea directory
- Open the project in Android Studio

Upgrading Android Studio 2.0 to 2.1 solved the problem.
