As an addendum to my previous article, there now also is an Android App „YellowRectangle“ that draws a yellow rectangle and terminates on the first touch event. It runs on Android version 4.0.3 (Ice Cream Sandwich MR1) and upward. It is written in Java and C++ and uses the Allegro game development library (http://liballeg.org/).
YellowRectangle running on Android 7.0 in the Genymotion emulator.
A complete project for Android Studio can be downloaded from my GIT repository.
