Question

To check if a network connection is available to the device, you can use a/an ________________ object.

Answer 1

To check network availability on a device, you can use a ConnectivityManager object in Android development. This object provides details about the connection status and type, although the previous getActiveNetworkInfo() method is deprecated in favor of newer APIs.

Step-by-step explanation:

To check if a network connection is available to the device, you can use a/an ConnectivityManager object. In Android development, the ConnectivityManager is a system service which provides information about the network connectivity status of the device. It can be used to determine if the device is connected to the internet and what type of connection is available (e.g., Wi-Fi, mobile data, etc.). The method getActiveNetworkInfo() was commonly used to check for network connectivity, but it has been deprecated in recent API levels. Developers are now encouraged to use the NetworkCapabilities API for checking the network status.

For example, in Android, you would use the following code to check for a network connection:

ConnectivityManager connMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
boolean isConnected = networkInfo != null && networkInfo.isConnectedOrConnecting();

Note: Always remember to include the necessary permissions in your AndroidManifest file when accessing the network state.
