This error generally comes when the phone/emulator is busy in some task which might make your application un-responsive. Just click on 'wait' for the phone to finish the background process. If the application still hangs, then you can go to manage application in the settings menu, open the application and 'force close' it from there.
ANRs (or Activity not responding) are common errors that you will come across when developing Android applications. One of the reason for its occurence is when the main thread(UI thread) of the application blocks for more than it should (5 seconds, I think).Further Reading... In your case, it is "com.android.phone" that is blocking for too long and not your application. You can either choose to wait or kill the process, as Ksh already mentioned.
