我怎么知道该应用程序已在android中完成？

Question

I hope to control app destroy.

I know that apps are generated through zygote. So if I want to control when app generated, I can do it using custom zygote.

However how do I know app finish? There are many case like fore, normal, abnormal and shutdown.

Is there a process that runs when all apps are shut down, like all apps are created via zygote?

In some case, finishAffinity() , finishAndRemoveTask() and finish() functions are used to finish the app. At that time what is process to handle these functions?

Answer 1

You will need to understand Android Activity Lifecycle for this, check this official document .

This method will be called after activity finish() , so you can override this method and do anything you want:

@Override
public void onDestroy() {
    super.onDestroy();
    // Do stuff you want here
}

Hope this helps!
