问题
I am using floodfill
algorithm to fill a black white picture with specific color with user touches.
I used this Question to use floodfill algorithm : How to use flood fill algorithm in Android?
the problem is sometime(whey i want to fill fast) I get Cannot Generate Texture From Bitmap
error and mBitmap.getPixel(x, y)
returns 0 and filling will be stop!
I can use copyPixelsToBuffer ( pictureBuffer )
instead of getPixel()
method According to last post of this link : http://www.developpez.net/forums/d1338782/java/general-java/java-mobiles/android/openglrenderer-cannot-generate-texture-from-bitmap/
But i do not know How to Change current Code.

I Solved that according to Shubhadeep Chaudhuri answer in below link :
Somebody ported J. Dunlap's Queue-Linear Flood Fill Algorithm to android here. I've tried it and it's pretty fast.
I've modified the copyImage() method which originally makes use of a class called Utilities which the author hasn't provided.
