what exactly I am doing is Copying an Image in ImageView using Buffer and Pasting it onto another Imageview using Buffer, but while Copying copyPixelsFromBuffer always throw. Attempt to invoke virtual method 'void on a null object reference.Special configuration, when bitmap is stored only in graphic memory. Bitmaps in this configuration are always immutable. It is optimal for cases, when the only operation with the bitmap is to draw it android bitmap copypixelsfrombuffer example

Flipping openGL texture from Bytebuffer before creating the Bitmap in Android. Ask Question 1. 1. (or at the same time). For example, can I use a matrix to flip the reading of the pixels by glReadPixels? Another notethought: maybe the cost of flipping the bitmap after creation is trivial because, since this relies on user interaction, it
