Check internet connection change via Broadcast Receiver in background. #android

NetworkChangeReceiver

public class NetworkChangeReceiver extends BroadcastReceiver{

	private static final String LOG_TAG = "NetworkChangeReceiver";
	private boolean isConnected = false;
	
	@Override
	public void onReceive(Context context, Intent intent) {
		Log.v(LOG_TAG, "Receieved notification about network status");
		isNetworkAvailable(context);
	}
	
	private boolean isNetworkAvailable(Context context) {
		ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
		if (connectivity != null) {
			NetworkInfo[] info = connectivity.getAllNetworkInfo();
			if (info != null) {
				for (int i = 0; i < info.length; i++) {
					if (info[i].getState() == NetworkInfo.State.CONNECTED) {
						if (!isConnected) {
							Log.v(LOG_TAG, "Now you are connected to Internet!");
							Toast.makeText(context, "Internet availablle via Broadcast receiver", Toast.LENGTH_SHORT).show();
							isConnected = true;
							// do your processing here ---
							// if you need to post any data to the server or get
							// status
							// update from the server
						}
						return true;
					}
				}
			}
		}
		Log.v(LOG_TAG, "You are not connected to Internet!");
		Toast.makeText(context, "Internet NOT availablle via Broadcast receiver", Toast.LENGTH_SHORT).show();
		isConnected = false;
		return false;
	}
		

}

Registering your receiver in manifest has been deprecated since API 24. It only works now if you use Context.registerReceiver(). Another solution I can think off is to use the AlarmManager to do scheduled checks. If you app depends on the connectivity change during it's lifecycle, than it won't be affected by using context registration.

This will only detect that the device is connected to a network but what if the network doesnot provide Internet connection?
So, basically I will suggest that with use of networking classes call the server api of your project which is working and if there is response then Connection established else not established.
