Debugging Android RuntimeException - Before my code even executes -


i'm not new java new android platform. i'm finding 1 of platforms shortcomings meaningful feedback on runtime crashes. fine in user code breakpoints apply, have crash on first run preventing project starting, , can't see way track down. can shed light?

dalvikvm[localhost:8626]         thread [<1> main] (suspended (exception runtimeexception))           activitythread.performlaunchactivity(activitythread$activityrecord, intent) line: 2585           activitythread.handlelaunchactivity(activitythread$activityrecord, intent) line: 2679            activitythread.access$2300(activitythread, activitythread$activityrecord, intent) line: 125          activitythread$h.handlemessage(message) line: 2033           activitythread$h(handler).dispatchmessage(message) line: 99          looper.loop() line: 123          activitythread.main(string[]) line: 4627             method.invokenative(object, object[], class, class[], class, int, boolean) line: not available [native method]           method.invoke(object, object...) line: 521           zygoteinit$methodandargscaller.run() line: 868           zygoteinit.main(string[]) line: 626          nativestart.main(string[]) line: not available [native method]       thread [<6> binder thread #2] (running)      thread [<5> binder thread #1] (running)

same on emulator , device.

i've seen reports of crashes these being caused inflation of invalid xml have removed xml's , resources project, 1 one, , same error remains! there tricks or instrumentation can apply try , more meaningful error message? thanks.

i found answer gleaning more information in these situations. page has useful information: http://www.mail-archive.com/android-developers@googlegroups.com/msg79386.html

by opening 'variables' tab in debug section of eclipse's views see there value named 'e' presumably 'exception' value 'classnotfoundexception'. clicking on saw fuller description saying class couldn't found. main activity, i'd renamed on late night before, , forgotten about. facepalm hope info helps someone!
