Answer 1

That's how i did it. I have created a IntentService and in onCreate method and I have registered networkBroadacst which check for internet connection.

public class SyncingIntentService extends IntentService {
    @Override
    public void onCreate() {
        super.onCreate();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            networkBroadcast=new NetworkBroadcast();
            registerReceiver(networkBroadcast,
                  new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
        }
    }

    @Override
    public int onStartCommand(@Nullable Intent intent, int flags, int startId) {
        onHandleIntent(intent);
        return START_STICKY;
    }
}

This is my broadcast class

public class NetworkBroadcast extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (Constants.isInternetConnected(context)) {
//            Toast.makeText(context, "Internet Connect", Toast.LENGTH_SHORT).show();
           context.startService(new Intent(context, SyncingIntentService.class));
        }
        else{}
    }
}

In this way you can check internet connection in whether your app is in foreground or background in nougat.
