How to Close Android Application

How to close Android application?

Just to answer my own question now after so much time (since CommonsWare commented on the most popular answer telling we should NOT do this):

When I want to quit the app:

1. I start my first activity (either splash screen, or whatever activity is currently at the bottom of the activity stack) with FLAG_ACTIVITY_CLEAR_TOP (which will quit all the other activities started after it, which means - all of them). Just make to have this activity in the activity stack (not finish it for some reason in advance).
2. I call finish() on this activity

This is it, works quite well for me.

how to close android app completely

To Quit Application on Button click use this code :

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);

Try it..

To kill the complete app and remove it from Runningapp list kill the app through its pid(its nasty)... use this lines before above code.

int pid = android.os.Process.myPid();
android.os.Process.killProcess(pid);

How to close my application programmatically in android?

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project

Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity's Enter the below code in Firstactivity's oncreate

if (getIntent().getExtras() != null && getIntent().getExtras().getBoolean("EXIT", false)) {
    finish();
}

and you are done....

How to close Android application in Kotlin

Grendel here is the absolute easiest two ways to close the Kotlin App
the first way will open the app on PageTwo when it is reloaded
not elegant but I included on the chance that someone has a Splash Screen

     moveTaskToBack(true);
     exitProcess(-1)

The second way is so simple and old you are going to scream
It will close the Kotlin App and when reloaded the MainActivity is shown first

finishAffinity()

I tested this with Nexus 9 API 26 I do not have a Samsung Galaxy S2
but feel free to mail me one ha ha
