I'm working on a Viveport submission. I have a questions in regards to this instruction:
"To apply wrapper-based DRM to your title, please upload your APK first. Then, download it after the wrapper-based DRM has been successfully applied. Afterwards, sign with your release key and prepare a release-ready APK for submission."
I've built my apk using the Unity IDE and Wave SDK, did the wrapper-based DRM, and have redownloaded the apk. I usually sign with my release key in Unity for Android products, but this appears to be a different situation. I tried with Android Studio and got build errors.
Can someone guide me to signing the downloaded apk with my release key? Thanks!
