Pixel perfect collision with Config.ALPHA_8

Question

I\'ve found this code of pixel perfect collision checking and used it in my code:

public  boolean isCollisionDetected(Bitmap bitmap1, int x1, int y1,
               


        

Answer 1

Android Config_Alpha_8 does not save color information, so when you draw the bitmap, adding the paint will do nothing, and all isFilled checks will return false.

Neat piece of code though.
