difference between swipe kill the app and force stop related to Application class

Question

I have an application that implements the Application class.

consider the following 2 scenarios:

A) open the application -> press home -> long-press home to see recent apps. -> swipe kill the application. in this case, the Application class onCreate function will be called without any interaction.

B)open the application -> press home -> long press on the app -> viw app info -> click on force stop. in this case, the Application class onCreate function will NOT be called.

My questions are:

1 - what is the difference between the two scenarios related to the Application life cycle.

2- Why when I swipe kill the app the Application onCreate method gets called?

P.S I already read this question and it doesn't answer my question.

UPDATE:

I noticed that this behavior in scenario A is not the same for all devices. for example, it happens on a Samsung phone but not on a Pixel phone. maybe it's up to the manufacturer?

Answer 1

• When you swipe the app, you kill only activity components. If there are any background services, they will continue working.

• When you force stop the app from app menu, you switch off all services working background. For example you will not receive push notifications after this action.
