Android: How to Enable/Disable Wifi or Internet Connection Programmatically

Question

Using the Connectivity Manager Class we can get access to either wifi or Internet Network:

ConnectivityManager connec = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);  // ARE WE CONNECTED TO THE NET if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||   connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED ) {   // ... } 

where 0 and 1 respectively refers to mobile and wifi connection

If my Android device is connected to both, can we switch between any of the networks or can we disable any of the networks? Like using a function:

connec.getNetworkInfo(0).setState(NetworkInfo.State.DISCONNECTED); 

Answer 1

I know of enabling or disabling wifi:

WifiManager wifiManager = (WifiManager)this.context.getSystemService(Context.WIFI_SERVICE); wifiManager.setWifiEnabled(status); 

where status may be true or false as per requirement.

Edit:

You also need the following permissions in your manifest file:

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