You have two choices:
- The first and the esay way, is to compile your project with older releases of GM:S below 1.4.1675 (also this way is that Tim Graupman suggest to use).
- Second is if you want/need to use newer releases, follow these easy steps: Open the properties window of OuyaSDK.ext extension inside GM:S, select the Android tab and remove all the code that appears on the "Inject to AndroidManifest.xml" and "Inject to Gradle dependencies" boxes. Click OK and try to compile your project now. This works fine for me, but Tim told me that this method may not work with the IAP functions, but I made a test app and worked fine, IAP functions included.
Hope these help you.
