You need to make custom resultreceiver class extended from
ResultReceiver
then implements the resultreceiver interface in your activity
Pass custom resultreceiver object to intentService and in
intentservice just fetch the receiver object and call
receiver.send() function to send anything to the calling activity in
Bundle object.
here is customResultReceiver class :
public class MyResultReceiver extends ResultReceiver {
private Receiver mReceiver;
public MyResultReceiver(Handler handler) {
super(handler);
// TODO Auto-generated constructor stub
}
public interface Receiver {
public void onReceiveResult(int resultCode, Bundle resultData);
}
public void setReceiver(Receiver receiver) {
mReceiver = receiver;
}
@Override
protected void onReceiveResult(int resultCode, Bundle resultData) {
if (mReceiver != null) {
mReceiver.onReceiveResult(resultCode, resultData);
}
}
}
implements the Myresultreceiver.receiver interface in you activity, create a class variable
Public MyResultReceiver mReceiver;
initialize this variable in onCreate:
mReceiver = new MyResultReceiver(new Handler());
mReceiver.setReceiver(this);
Pass this mReceiver to the intentService via:
intent.putExtra("receiverTag", mReceiver);
and fetch in IntentService like:
ResultReceiver rec = intent.getParcelableExtra("receiverTag");
and send anything to activity using rec as:
Bundle b=new Bundle();
rec.send(0, b);
this will be received in onReceiveResult of the activity. You can view complete code at:IntentService: Providing data back to Activity
Edit: You should call setReceiver(this) in onResume and setReceiver(null) in onPause() to avoid leaks.
