Managing Your WiFi using WiFi Manager APP for Android

The Wifi Manager APP for Android represents the Android WiFi Connectivity Service. It can be used to configure Wi-Fi network connections, manage the current WiFi connection, scan for access points, and monitor changes in WiFi connectivity.  As with the Connectivity Manager, access the WiFi Manager using the getSystemService method, passing in the Context.WIFI_SERVICE constant.

To use the WiFi Manager, your application must have uses-permissions for Read/Write WiFi state. the WifiManager also provides low-level access to the Wi-Fi network configurations, giving you full control over each configuration setting and allowing you to completely replace the native Wi-Fi management application. Later in the section, you’ll be introduced to the API used to create, delete, and modify network configurations.
