Waiting until onReceive runs and stop

Main Purpose: Reading an access point's properties freshly, and use it.

I tried to add a custom BroadcastReceiver class to my activity.

If it is true; I learned that; onReceive runs after intent action, (here: WifiManager.SCAN_RESULTS_AVAILABLE_ACTION).

But i think i must wait until onReceive finishes running to get a fresh r11.

When i debug the method "useResults"; "use r11, modify r11" lines runs first, after a while onReceive starts to run.

public class MainActivity extends ActionBarActivity implements OnTouchListener{

    int r11=0;


    public void useResults(){

             mainWifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);

             receiverWifi = new WifiReceiver();
             registerReceiver(receiverWifi, new IntentFilter( WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
            mainWifi.startScan();

             //use r11
             //modify r11
             //do something with r11

        }

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

        @Override
        protected void onResume() {
            registerReceiver(receiverWifi, new IntentFilter(
                    WifiManager.SCAN_RESULTS_AVAILABLE_ACTION));
            super.onResume();
        }

        class WifiReceiver extends BroadcastReceiver {
            public void onReceive(Context c, Intent intent) {
                wifiList = mainWifi.getScanResults();
                for (ScanResult result0:wifiList) {
                    String ssid0 = result0.SSID;



                    if(ssid0.compareTo("anID")==0){

                        r11=result0.level;

                    }
                }
            }
        }

}

The BroadcastReceiver is an inner class, there's nothing wrong or dirty in using it to call methods on the class. That's what inner classes are for.

Just create a separate method

void doR11Results(){
         //use r11
         //modify r11
         //do something with r11
}

... and call it from onReceive. Super simple!
