I need to close my application when the user presses the back button from an activity that is not the main activity(i.e the launcher activity). The answers I've seen so far actually works on the main activity of the application(i.e the launcher activity)

You can use 

@Override 
public void onBackPressed() { 
    <YourActivity>.this.finishAffinity();
}

You can clear the back stack while you open the activity using flag :

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);

And your appliction will be finished when you go back.

Or may be Try to open same activity but clear the back stack and finish it at same time.(not tested)

 Intent intent = new Intent(this, YourCurrentActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); 
startActivity(intent);
finish(); // call this to finish the current activity

You can use this

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