Programmatic Control of Network Connectivity in Android: Enabling/Disabling Wi-Fi and Internet

Intro:
Maintaining reliable network connections is crucial for seamless mobile app functionality. This article explores how to programmatically enable or disable Wi-Fi and internet connectivity in Android using the Connectivity Manager and Wi-Fi Manager classes.

Getting Network State:
The Connectivity Manager provides the ability to retrieve information about network connections. By checking the state of NetworkInfo objects, you can determine if the device is connected to either a mobile or Wi-Fi network.

Enabling/Disabling Wi-Fi:
To enable or disable Wi-Fi, you can use the Wi-Fi Manager. Simply set the Wi-FiEnabled property to true or false. To use this feature, you must declare 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" />

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

Note:
It's not possible to programmatically enable or disable the mobile data connection using the Connectivity Manager or Wi-Fi Manager alone. You may need to use other mechanisms, such as sending an intent with the desired action, to achieve this functionality.
