I have two activities: ActivityA and ActivityB. In each activity, I have create a button with onClick method to startActivity to another activity.

ActivityA.java

public void doNext(View view) {
    startActivity(new Intent(ActivityA.this, ActivityB.class));
}

ActivityB.java

public void doBack(View view) {
    finish();
}

When I press doNext it navigated me to the ActivityB, I kill the app on the ActivityB, but the onDestroy on ActivityA got called (it must be the onDestroy on the ActivityB). Can somebody explain me what happened?

This is the flow of my program: onCreate (A) -> onStart (A) -> onResume (A) -> onPause (A) -> onCreate (B) -> onStart (B) -> onResume (B) -> onStop (A) -> Kill the app (swipe to dismiss) on ActivityB -> onPause (B) -> onStop (B) -> onDestroy (A) .

This is expected behavior. Swiping the app from recent kills the application process of which both the activities are child. – Muhammad Babar Apr 09 '18 at 07:43
@MuhammadBabar: but i thought it would call `onDestroy (B)` instead of `onDestroy (A)` – Call me K Apr 09 '18 at 07:46
@CallmeK Android won't work on your thoughts buddy, it's better to understand the activity life-cycle. – android_griezmann Apr 09 '18 at 07:56
how do you check if onDestroy(B) is not called? – Sagar Apr 09 '18 at 07:56
@Sagar: I put the `Log` in every lifecycle callback methods (onCreate .... onDestroy) in each activity – Call me K Apr 09 '18 at 08:00
