I'm trying to figure out a java.lang.RuntimeException problem in my app.
When I look at the logcat, it will show something like this:
12-19 09:29:38.055: WARN/dalvikvm(716): threadid=3: thread exiting with
uncaught exception (group=0x4000fe70)

I want to see the "11 more" lines in the error logging. How do I view
those?
Thanks.
