builder.setSmallIcon(R.mipmap.ic_launcher);//Set the image
builder.setContentIntent(pendingIntent);//execute intent
Notification notification = builder.getNotification();//convert the builder object to a normal notification
startForeground(1,notification);//Make MyService a foreground service and show it in the system status bar.
