I have an ARM64 React Native toolchain sitting on blocks for ChromeOS. Caret is the IDE for this but Android SDK is truly lacking for ARM the build tools are base level. There is a guide floating around out there to make your own too. Looking forward to more stuff like this because essentially you get realtime Native app development with this but hooking into the debugger via crosh terminal is hard. Smoothing out the rough edges on this and then wow! You will have a powerhouse. NativeScript? Even better in theory.
