How to keep my application alive in background, even after closing the app and clearing off the ram…
I know this is possible without a ROOT, beacuse Reddit does it for notification purposes…
Thanks in advance…

You will have to use Android’s [lifecycle functions](https://stackoverflow.com/questions/8515936/android-activity-life-cycle-what-are-all-these-methods-for) like onStop() to save the necessary data that can be used in onRestart().

You will need the [AsyncTask](https://developer.android.com/reference/android/os/AsyncTask) class.(up till Android 10). At the moment I don’t have the time to make an programmatically example, but you could start trying to implement [this](https://google-developer-training.github.io/android-developer-fundamentals-course-practicals/en/Unit%203/71_p_create_an_asynctask.html), and [this.](https://code.tutsplus.com/tutorials/android-barometer-logger-acquiring-sensor-data--mobile-10558)
