FloodFill Algorithm does not work for me
I created a simple paint application on android. For "fill with color" feature I found a sample code on stackoverflow. But the code does not work properly for me. I get no error when I run app but nothing changed in my image. What is wrong? My whole project source code is here. I copied AsyncDoldur and FloodFill class from this post.
I think problem is invalidate() function. Where I should use it?
