Android Scan for Wi-Fi networks

Question

I am trying to check wireless networks and find this useful source on the network. Unfortunately, it does not work, and I have no idea why. My problem is that I can’t wait 10 minutes for the result - I need them for a few seconds and thought about setting a boolean variable that expects false as soon as I get the result ... well, it works forever. .nothing seems to be received. Any ideas? Thank.

        IntentFilter i = new IntentFilter();
        i.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
            registerReceiver(new BroadcastReceiver(){
                @Override
                public void onReceive(Context c, Intent i){
                    // Code to execute when SCAN_RESULTS_AVAILABLE_ACTION event occurs
                    mWifiManager = (WifiManager) c.getSystemService(Context.WIFI_SERVICE);
                    wireless =  mWifiManager.getScanResults(); // Returns a <list> of scanResults
                    waiting = false;
                }
            }
        ,i);
        // -- End Wifi Sample 


        mWifiManager.startScan();


        while (waiting)  { 
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            Log.d("PROJECT1","Wifi WAITING");
        }

Answer 5

You should write in the BroadcastReceiverfollowing way:

• Register it

• Then run Scan and do this

  if (WifiManager.SCAN_RESULTS_AVAILABLE_ACTION.equals(action)) {
  
  super.onReceive(context, intent);           
  //Scan is ok, just need few seconds!
  }
