This is happening over and over again. People say that their Android application isn't working, crashing etc, and not providing us with vital information, error from LogCat. Without it debugging is slow and annoying since we don't know where to start.
So what i suggest is, that when someone uses Android as a tag, he would be advised to provide LogCat information if he is asking about 'broken' code, or at least tell where it is crashing.
Example of such case: Android Unknown Application Crash
Always the same comments come:
"How about letting us see the crash log so we can at least have a clue where to look? – >Paul.s"
"'adb logcat' is your friend. It will show you a stack trace, pointing at the exact line and >source file that caused the crash. – kisplit"
