I have honed in on exactly what the problem is, and it doesn’t match anything I have seen online so far. The context is that I am trying to install my build on a friends headset, from his PC. We are using the APK becuase we were having problems with the BAT file not finding the Android SDK since that path is baked into the build from what I can tell (In the Android packaging settings in Unreal). So my exact question is how do I get the APK to work, that would solve our problem. OR, how do I manually tell the PC to use a local location for the SDK, and not the one that is in the package (if that is even possible).
