I am doing memory analytis for my application, using dumpsys and below command adb shell dumpsys meminfo I get the dalvik heap and native heap memory .....but I also see GPU memory adb shell dumpsys gfxinfo I am failing to understand when is GPU memory used and when is native memory used for bitmaps.Also the texture view, surface view is used where?

More clarity needed in analysis.

In Android memory analysis, adb shell dumpsys meminfo shows Dalvik Heap (Java/Kotlin objects, software-rendered Bitmaps) and Native Heap (C/C++ allocations, hardware-accelerated Bitmaps). When hardware acceleration is enabled (setHardwareAccelerated(true)), Bitmaps are stored in Native Heap instead of Dalvik:

bitmap.setConfig(Bitmap.Config.HARDWARE)

GPU memory, analyzed via adb shell dumpsys gfxinfo, is used when rendering with OpenGL/SurfaceFlinger, storing textures and shaders. TextureView relies on the GPU for smooth animations, whereas SurfaceView provides a separate rendering surface, making it efficient for media playback. Identifying where Bitmaps are stored helps optimize memory usage and prevent OOM(Out of Memory) errors.
