Hi
I am a little confused about when ServiceConnection.onServiceConnected
is actually called. After debugging I realised that it happens after the
UI is built. When I call bindService() it returns an immediate "true",
but the onServiceConnected() method isn't even called by then. So I
cannot call methods from the stub in onResume or onStart()?
So, service is still NULL, for example in an onResume() method:
onResume() {
sc = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder binder) {
service = [whatever].Stub.asInterface(binder);
}
@Override
public void onServiceDisconnected(ComponentName name, IBinder binder)
{
service = null;
}
};
boolean bound = bindService(bla,bla,bla);
if(bound && service!=null) {
//gets never called, service is still null while bound is true
}
}
onPause() {
unbindService(sc);
}
After onResume(), when the Activity is already displayed,
onServiceConnection() gets eventually called. But I cannot get any
information from the service before then, as described above in
onResume().
Furthermore, I observed that an unbindService() does not call
onServiceDisconnected. So, if the Activity was stopped and not
destroyed, the service variable is not null. If it was destroyed, it is
only null because it is newly created.
Can someone reproduce this behaviour? By the way, the service was
already started in onCreate().
Regards
Christoph
