How to get the connection strength of Wifi access points?

Question

I am building an application reading the signal strength of each available Wifi access point.

I\'ve written code like:

    wifi = (WifiManager) getS         


        

Answer 1

    WifiManager wifiManager = (WifiManager)
    MonitorActivity.this.getSystemService(Context.WIFI_SERVICE);

    wifiManager.addNetwork(conf);

    int numberOfLevels = 5;
    WifiInfo wifiInfo = wifiManager.getConnectionInfo();
    int level = WifiManager.calculateSignalLevel(wifiInfo.getRssi(), numberOfLevels);

    Log.e("level", "" + level);
    // you will get the levels. Using these levels you can calculate strenghts.
