I added following two methods in my Activity:
@Override
protected void onSaveInstanceState(Bundle outState) {
outState.putBoolean("serviceBound", serviceBound);
}
@Override
public Object onRetainNonConfigurationInstance() {
return serviceConnection;
}
And in onCreate() of the Activity, I added:
if(getLastNonConfigurationInstance()!=null){
serviceConnection =
(ServiceConnection)getLastNonConfigurationInstance();
}
if(savedInstanceState!=null){
serviceBound = savedInstanceState.getBoolean("serviceBound");
}
if(serviceBound == false){
bindService(new
Intent(getApplicationContext(),MessengerService.class),
serviceConnection, BIND_AUTO_CREATE); //!!!
Log.d("MyMediaPlayerActivity","Activity: bindService()");
}else{
Log.d("MyMediaPlayerActivity","Activity: serviceBound == true");
}
Nevertheless, after my log "Activity: serviceBound == true" is
printed, Android complains "Activity has leaked ServiceConnection that
was originally bound here" at the line with !!! mark.
