title: How do I get the finger/screen contact area in Android?
body: <p>I am currently trying to get the shape of my finger as it touches my tablet screen (Android 10).</p>
  <p>I tried it with Android Studio but it seems impossible (I can just get the size and draw a circle, but I want the exact shape). I'm trying with Unity, but I think it works the same as Android Studio. I made a 200*200 square, consisting of 1 pixel GameObject squares, and I thought I could recover all the pixels that had been touched, but for 1 touch, only 1 pixel is detected (x,y). How to trigger multiple buttons with a single click in Android (or Unity)?</p>
  <p>Does anyone know if this is possible and how to do it? Can I check the state of each pixel in a loop?</p>
  <p>Thanks in advance.</p>
