Animate CC to JSON for Android Studio

Hi

I want to create some little animations for my friend to add to his Android Apps that hes creating. He says he uses lottie at the moment along with Android Studio. I just want to create some little tiny animations like stars and then basically give him this in JSON format so he can add it to his game. I have tried using AIR for Android and downloaded the SDK and when I publish I get swf, xml, apk. The APK is obviously the compiled version, the SWF doesnt work and I dont think compatible anyway and the XML file is more or less blank. Can anybody help me export an animation in Adobe animate for use as a JSON file or at least something he can work with? p.s the publish preview works fine, he said the APK file works fine, but I need to create animations for him without compiling as an APK as I want to create assests rather than the application itself. Thanks
