make homebutton call onFinish()
<p>all i want to do is call onFinish() when the homebutton is pressed, i want to do this so i always enter the main activity when opening my app, i dont want the user to jump back to where he left of(i know this is a bad concept in most cases but for my app it makes more sense to always enter into main activity)</p>

<p>thank you!</p>
