for some reason my code when I exit crashes my phone... so if I am paused or never start my app and hit the Quit command it crashes but if the app is running and I quit then it exits fine... my question is why and what is the fix...
[HIGH]public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.retrieve_location_button:
showCurrentLocation();
break; case R.id.bTrack:
if (isTracking) {
pause(); }
else { resume(); }
break;
case R.id.bQuit:
quit();
break;
[/HIGH]this is the error log
