How can I programmatically close an application?

Question

I am looking for code for a button that completely closes my app.

I tried with some stuff from Google, but my app is still running in the background. I need to close

Answer 1

You can close all activities from background and when re-open the app It starts from first activity

this.finish();
Intent intent = new Intent(getApplicationContext(), CloseApp.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

You can close all activities from background and when re-open the app It starts from paused activity[where you closed] activity

    this.finish();
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
