How to Control Wi-Fi and Internet Connectivity in Android Programmatically

The Connectivity Manager class allows us to access the device's network connectivity information. To determine if the device is connected to a network, we can use the following code:

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 ) {
  // ...
}

However, this method does not allow us to switch between network connections or disable them programmatically.

Enabling or Disabling Wi-Fi

To control Wi-Fi connectivity, we can use the WifiManager class:

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

where status is either true to enable Wi-Fi or false to disable it.

Required Permissions

The following permissions are required in the manifest file:

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

Note: Disabling Wi-Fi or Internet connectivity may affect the functionality of other applications on the device. It is important to consider this before making any changes.
