Hi!
I'm reading the book Professional Android 2 Application Development
from Reto Meier. I'm stuck on page 298.
I need having a Service in the app, and almost it works, but not
quite.
I get my Service to run, but cannot bind to it (so my reference
serviceBinder is never initialized; e.g. I get the
NullPointerException. The following code snippet is never run, and I
am confused where to put it:
Please note that I return Service.START_STICKY; from
onStartCommand( ...) from the Service.
Following makes the service to run:
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
// Bind to the service
Intent bindIntent = new Intent(MazeAlgorithm.this,
MazeAlgService.class);
bindService(bindIntent, mConnection, Context.BIND_AUTO_CREATE);
}
but this code below is NEVER run (so serviceBinder is never
initialized):
private ServiceConnection mConnection = new ServiceConnection(){
public void onServiceConnected(ComponentName className, IBinder
service){
// Called when the connection is made.
serviceBinder = ((MazeAlgService.MyBinder)
service).getService();
}
public void onServiceDisconnected(ComponentName className){
// Received when the service unexpectedly disconnects.
Context context = getApplicationContext();
serviceBinder = null;
}
};
MazeAlgService is the service, called from the class MazeAlgorithm.
Where to shall I put the code above in the context of the Activity?
Nicest thanks to all of you (and just for info: I'm new to this
group... :-) )
/Ivo
