Android
Android is a mobile operating system developed by Google used by most smarthphones and tablets.
General support
Starting with 4.4, Android is no longer in an experimental state. All engine features are fully supported on it, but Stride remains more focused on the desktop side and may be lacking some mobile-specific functionality.
However, there aren't currently many people looking after Android. The engine is tested on the platform before any change is merged to the source code, but sometimes some regressions could slip by, requiring manual testing from active maintainers. If you want to make sure that all engine features continue being supported on it, consider becoming a contributor.
