Android - implementing startForeground for a service?

Question

So I\'m not sure where/how to implement this method to make my service run in the foreground. Currently I start my service by the following in another activity:

<

In my case It was totally different since I was not having activity to launch the service in Oreo.

Below are the steps which I used to resolve this foreground service issue -

public class SocketService extends Service {
    private String TAG = this.getClass().getSimpleName();

    @Override
    public void onCreate() {
        Log.d(TAG, "Inside onCreate() API");
        if (Build.VERSION.SDK_INT >= 26) {
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
            mBuilder.setSmallIcon(R.drawable.ic_launcher);
            mBuilder.setContentTitle("Notification Alert, Click Me!");
            mBuilder.setContentText("Hi, This is Android Notification Detail!");
            NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

            // notificationID allows you to update the notification later on.
            mNotificationManager.notify(100, mBuilder.build());
            startForeground(100, mBuilder.mNotification);
        }
        Toast.makeText(getApplicationContext(), "inside onCreate()", Toast.LENGTH_LONG).show();
    }


    @Override
    public int onStartCommand(Intent resultIntent, int resultCode, int startId) {
        Log.d(TAG, "inside onStartCommand() API");

        return startId;
    }


    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "inside onDestroy() API");

    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }
}

And after that to initiate this service I triggered below cmd -

adb -s " + serial_id + " shell am startforegroundservice -n com.test.socket.sample/.SocketService

So this helps me to start service without activity on Oreo devices :)
