Button button = (Button) findViewById(R.id.btn1); button.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
         activity.finish(); // to move out of activity
           // to move out of the app
           //activity.finishAffinity();
    
    }
});
}

}

Is the correct scenario to close the app by a button / by user action?

You should have a really well scenario to use this case.

Is against application processing principles.

Android framework only kills applications only if the resources are needed. Also has extra benefits: App startup is faster if the process is alive.

 Activity.finish(); // will finish the current activity.
 Activity.finishAffinity()  //removes  Activitys belonging to a specific application from the current task

If it's the case you want to "exit" the application I would recommend an approach where you "simulate" closing the application. (you bring the HomePage in front)

Intent homePageIntent= new Intent(Intent.ACTION_MAIN);
homePageIntent.addCategory( Intent.CATEGORY_HOME );
homePageIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  
startActivity(homePageIntent);

Oh another tip: Before asking a question try to search your question on Google. You could have noticed that your question was asked multiple times.

A great example.
