Getting WI-FI strength in percentage

The below snippet helps to find the WI-FI strength in the percentage.

public static int getWifiStrength(Context
{
          try
          {
              WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
              int rssi = wifiManager.getConnectionInfo().getRssi();
              int level = WifiManager.calculateSignalLevel(rssi, 10);
              int percentage = (int) ((level/10.0)*100);
              return percentage;
          }
          catch (Exception e)
          {
              return 0;
          }
}


We have to pass context of the activity from where we are calling this method.

It will return WI-FI strength in percentage. In case if any exception found then it will return 0;
