Bro ..... could this even work when the app is closed.????....I mean that when it is not running in the background... For example take the default alarm app......even when we close the app....it gives the notification....
yes, just don't call stopService(foreservice) in onDestroy() method in MainActivity.java class. and the notification will live on after you close the app
Will this keep the app running in the background if the user gets a call while using the app??? This is especially a problem if the app is used for extended periods of time.
