If you’ve recently upgraded to IntelliJ 10.5 and are using it for Android development you might run into an odd issue where when you try to debug IntelliJ hangs and says “Waiting for ADB” and then freezes. The IDE does not respond to any events and eventually you have to kill it.

Something changed in the config values for IntelliJ (from what I can tell through my research online) and the best way to get around this error is to invalidate the caches and restart the IDE. After that, you should be golden.

Enjoy. 🙂
