You haven't really given enough information for a definitive answer. Are you
calling the following somewhere?
public void startService(){
super.onStart();
But, I would also put an "if (b != null)" in as the third line to stop the
next exception.
Can you post your Stack trace or logcat? It should have enough information
to figure out what the problem is.
Sincerely,
Brad Gies
