Answer 1

Here is how to turn on and turn off wifi in android.

First you need to declare the following in your manifest file

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.UPDATE_DEVICE_STATS"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>

After doing it that on your Activity class

private WifiManager wifiManager;
@Override 
public void onCreate(Bundle icicle) {
 ....................
 wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE);
 if(wifiManager.isWifiEnabled()){
 wifiManager.setWifiEnabled(false);
 }else{
wifiManager.setWifiEnabled(true);
}

}

Explanation

Get the Wifi service from our system

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

Check the our wifi is currently turned on or turned off

if(wifiManager.isWifiEnabled()){

Turn on/off our wifi wifiManager.setWifiEnabled();
