Question

Let’s say that I’ve the following main activity:

public class MwConsoleActivity extends Activity {

    private classChild child = null;    

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        child = new classChild();
    }
}

Then consider the implementation of the class “classChild”:

public class MwBondingAgent extends SapereAgent {

    MwBondingAgent(){}

    public void AddEventListener(childAddedEvent event) {

       //Send the data of event back to the main activity

    }
}

I’ve tried to use IntentServices but was not able to receive the values back to the main activity. What would be the approach I’ve to take?

Cheers

You can use and intentFilter to listen for broadcasts.
Add this to the activity:

 IntentFilter intentFilter = new IntentFilter(
                "com.unique.name");
        mReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                //extract our message from intent
                String msg_for_me = intent.getStringExtra("some_msg");
             }
        };
        //registering our receiver
        this.registerReceiver(mReceiver, intentFilter);

In your class add this to the part you want to notify the activity:

Intent i = new Intent("com.unique.name").putExtra("some_msg", "I have been updated!");
this.sendBroadcast(i);
