StartActivity in onPause () does not work after opening a new application

Question

I start the second action when my first action is paused.

FirstActivity.java

@Override
public void onPause(){
    super.onPause();
    startActivity(new Intent(this, SecondActivity.class));
}

When I click on the home screen button, SecondActivity will start, but with a delay. There is enough time in this delay to open a new application (for example, a messenger). However, when I open a new application, SecondActivity will no longer start (it will not even call the onCreate SecondActivity method).

How can I launch SecondActivity even when I open a new application?

Answer 1

onBackPressed() onPause().

@Override
public void onBackPressed()
{
    startActivity(new Intent(this, SecondActivity.class));
    super.onBackPressed();
}
