Can't bind to Service

Question

I have an aidl file defined as follows:

package com.erbedo.callalert;

interface RemoteCallAlert {
    void notifyCallEnded();
}

The service is:

package com.erbedo.callalert;

public class CallAlert extends Service {

    Filter callListener;

    private final RemoteCallAlert.Stub mBinder = new RemoteCallAlert.Stub() {
        @Override
        public void notifyCallEnded() throws RemoteException {
                  // TODO
        }
        };

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Toast.makeText(this, "CallAlert Created", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Toast.makeText(this, "CallAlert Destroyed", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Toast.makeText(this, "CallAlert Started", Toast.LENGTH_LONG).show();
        callListener = new Filter();
        TelephonyManager tm = 
            (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
        tm.listen(this.callListener, PhoneStateListener.LISTEN_CALL_STATE);
    }

    public void callEnded() {
          // TODO
    }
}

and the Activity that has to bind to the service is: package com.erbedo.callalert;

public class DummyStart extends Activity {

    Filter callListener;
    RemoteCallAlert mService;

    private ServiceConnection mConnection = new ServiceConnection() {
        public void onServiceConnected(ComponentName className,
                IBinder service) {
            Log.d("CONNECT","OK");
        }

        public void onServiceDisconnected(ComponentName className) {

        }
    };

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout l = new LinearLayout(this);
        setContentView(l);
        this.startService(new Intent(this, CallAlert.class));
    }   
}

The onServiceConnected isn't called. Am I missing something obvious?

Answer 1

startService() does not use a ServiceConnection. bindService() does.

Answer 2

Intent intent = new Intent(CallAlert.class.getName());
bindService(intent, mConnection, Context.BIND_AUTO_CREATE);

Answer 3

The onServiceConnected isn't called.

For binding with the service you need to call bindService(). It provide the persistence connection, and after connection establishment onServiceConnected() is called.

Second point:- If you are using AIDL IPC mechanism then I think you need the communication between 2 diff processes/Application. Here you need to have same copy of .aidl file in both service and Activity side in same PACKAGE. Then you need to modify little bit in your Activity side..
