Exactly this. Imagine you are trying to build some kind of camera app that involves layering on effects or filters. You've got to have fine grain control over all the camera sensors, the gpus for rendering and compute, and potentially neural accelerators for some inferencing. How do you begin to do this on Android? Vulkan itself is hard enough. Now try adding Android NN API, and Camera 1/2/X with it's image processors. Now make it work across more than a single OEM hardware device. None of this is as simple as iOS side with a clean API that works together across GPU, NN and camera, in native code.
