I'm trying to develop a simple game for Android like the famous DiffIt.
1) I want that in this game to be two images that divided the screen in two parts.
2) The images are the same image but with little difference, all the difference are collected in xml file with the coordinates.
3) If you touch the display over the difference of the images must appears a rectangle that show the difference, if you have touch the correct location.
Ok, this introduction only for explain my goal.
But I'm very very beginner in Android and I need your help.
The point 1 and 2 work for now, but I need a tips for the point number 3.
Have any idea?
