#1. Make sure to add a local.properties file in the android folder with this line: sdk.dir=C:/Users//AppData/Local/Android/Sdk

#2. Make sure to replace the requestFrame method in node_modules@azesmway\react-native-unity\android\src\main\java\com\azesmwayreactnativeunity\UPlayer.java with the following if using Unity 2023 and up: public FrameLayout requestFrame() { try { // Attempt to invoke getFrameLayout() for the newer UnityPlayer class Method getFrameLayout = unityPlayer.getClass().getMethod("getFrameLayout"); return (FrameLayout) getFrameLayout.invoke(unityPlayer); } catch (NoSuchMethodException | IllegalAccessException | InvocationTargetException e) { // If it is old UnityPlayer, use isInstance() and cast() to bypass incompatible // type checks when compiling using newer versions of UnityPlayer if (FrameLayout.class.isInstance(unityPlayer)) { return FrameLayout.class.cast(unityPlayer); } else { return null; } } }
