How can I send result data from Broadcast Receiver to Activity

You can call the receiver from your activity. If you don’t want to add the logic of the receiver in you activity you can use an abstract receiver.

You abstract receiver:

public abstract class SmsReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
           //Add you receiver logic here
           ...
           ...
           onNewPosition();
        }

    protected abstract void onNewPosition();

}

In your activity:

public class MyActivity extends Activity {

    private smsReceiver smsReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_one_position);
        smsReceiver = new smsReceiver() {

            // this code is call asyncrously from the receiver
            @Override
            protected void onNewPosition() {
            //Add your activty logic here
            }

        };
        IntentFilter intentFilter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
        intentFilter.setPriority(999);
        this.registerReceiver(smsReceiver, intentFilter);

    }

     @Override
        protected void onPause() {
            super.onPause();
            this.unregisterReceiver(this.smsReceiver);
        }

}

I hope it will help you…
