ANR Input dispatching timed out

Is there a way of finding out where my app threw an ANR (Application Not Responding). I took a look at the traces.txt file in /data and I see a trace for my application. This is what I see in the trace.

How can I find out where the problem is? The methods in the trace are all SDK methods.
