Wow! 120 MB is a LOT! 😱

Thank you for the test case. We are just now in the process of making the Rive renderer default on Android & iOS. The currently-default renderer on Android will fill up its cache quickly on an idle animation like this, leading to large memory usage like you're seeing here.

If you enable the pre-release Rive renderer do you see better memory usage? (I don't recommend releasing with the Rive renderer yet, since there are still some devices with issues, but it should give you an idea of where things will land in the near future.) Also note that the Rive renderer currently uses OpenGL on Android. We are actively finishing up the Vulkan implementation, which will also get better memory usage.
