This happens due to many reasons. I can't diagnose without your stack traces.

The most common reason for this error is when you are doing an CPU intensive task in a UI thread. Use threading or AsyncTask to delegate such CPU intensive work.

Is any ANR thrown? If so go in DDMS->File Explorer -> data/anr/traces.txt and check at which point ANR occurred.

keyDispatchingTimedOut when you are doing heavy calculation on main thread. Move what you are doing in a new background thread (if possible)
