title: Android: adding a red arrow to a picture programmatically
body: <p>The user will be taking a picture of som playing cards, and the app will determine what card and where it should be placed to continue. Once this is calculated, i would like to have an arrow from the cards position to where it should be placed for the user to see.</p>
  <p>Is this even possible? and where would i be able to learn about it?</p>
