Handling Internet Connectivity Changes in Android

The question centers on the need for a Broadcast Receiver that can monitor changes in internet connectivity, as the existing code only detects connectivity changes.

To address this, here's an alternative approach:

public class NetworkUtil {
    public static final int TYPE_WIFI = 1;
    public static final int TYPE_MOBILE = 2;
    public static final int TYPE_NOT_CONNECTED = 0;

    public static int getConnectivityStatus(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        if (activeNetwork != null) {
            if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
                return TYPE_WIFI;

            if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                return TYPE_MOBILE;
        }
        return TYPE_NOT_CONNECTED;
    }
}

This method determines if the device is connected to WiFi or mobile data.

public class NetworkChangeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {
        int status = NetworkUtil.getConnectivityStatus(context);
        if ("android.net.conn.CONNECTIVITY_CHANGE".equals(intent.getAction()) {
            if (status == NetworkUtil.TYPE_NOT_CONNECTED) {
                // Handle loss of internet connectivity
            } else {
                // Handle restoration of internet connectivity
            }
        }
    }
}

This BroadcastReceiver monitors connectivity state changes and triggers actions based on the current status. Remember to include the appropriate permissions and register the receiver in your AndroidManifest.xml:
