Rotating a bitmap using JNI & NDK

Question

Background:

I\'ve decided that since bitmaps take a lot of memory which can cause out-of-memory errors easily, I will put the hard, memory consuming work on C/C++

Answer 1

Since you're using ARGB_8888 format every pixel is an uint32_t not uint16_t. Try changing your rotated Bitmap creation to use uint32_t for source and destination arrays and it should work better.
