Hi
Log cat indicate that you have nullpointer exception on line number "302" of  your "OnAir.java" class file.
Check in file, what are you using on 302 line number? and is that proper instantiated before use?

Well, for starters, you didn't really give us any information to help you solve the problem.  But, for the crash, take a look at the logcat output... It usually gives some pretty good information about the cause of a crash.

Hi, 

I have created a library project containing a service. When I first build it and install it on my phone it works fine, but when I create the second build using the same library project and install it on my phone, the first build works fine but the second one crashes. Also when I run the second build and I go into (Setting>Application>Running Application) the service is running of the first application. That might explain the reason of crashing of second build.

Can anyone tell me what am I doing wrong.
