Hi, I am developing a mobile application that involves complex image processing operations. The app is designed in Java while the core image processing ops are implemented in native code, and compiled using the Android NDK.
Now, I know that native code will *not* yield any significant performance improvement over Java code, and that the NDK purpose is only to support re-use of code libs (or to quickly integrate legacy code). Now to my question: are there any resources/tips-n-tricks/white papers/ samples on optimizing image processing algorithms for Android? To be even more specific, I am looking out for optimizing memory operations (cache misses, memory stalls, etc.). I profiled my application code and came to the conclusion that memory issues are causing the *maximum* performance penalty. (Nothing surprising over there, it is expected, but just verified with profile data as well). Any help is appreciated. Anyone else tried to develop image processing algos for Android? Any tips/resources? Thanks a lot! Amit -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
