Hey hey, we're working on releasing our first app in various stores to check effort / payoff, and are struggling with Huawei. We made it through the review and our app is live and works, but in-app purchases don't work. Checking logcat on device, I see dozens of E/HMSSDK_HMSPackageManager: Failed to find HMS apk, which seem like UDP internals, one or two blocks of E/HMSSDK_BridgeActivity: In initialize, Failed to create 'IUpdateWizard' instance.Invalid name: I/HMSSDK_BridgeActivity: Enter finish. I/HMSSDK_UpdateAdapter: onBridgeActivityResult I/HMSSDK_[ACCOUNTSDK]AccountSignInHubActivity: version check failed I/HMSSDK_AvailableAdapter: user response 28 then the big one that seems the real cause of our issues: E/UnityDistPlatform: [HUAWEI] sign in failed, status: 28 I/UnityDistPlatform: [HUAWEI] Setup finished. I/UnityDistPlatform: [HUAWEI] Init Fail: sign in failed E/libc: Access denied finding property "ro.serialno" I/UnityDistPlatform: [HUAWEI] UDP Version: v2.1.4 and finally blocks about the error getting caught in my IInitListener's OnInitializeFailed and associated obfuscated callstack. As a result of the errors, IAPs fail because they're not initialized correctly. Searching the web, I found someone with a similar message but different error code being recommended to update the HMS Core (which we don't install manually since we use UDP, so how would one even update that). Another person had issues with their SHA256 not being copied correctly, which is also not the case here. We + copied Pub Key and App Secret from Huawei to UDP, and + the SHA from UDP to Huawei. + App is signed with our own output.zip via the UDP guide, and + until we sent our first release through review, there was no setting picked on Huawei. It now shows "Export and upload key and cert" as selected, and shows the same steps as the UDP guide showed earlier. I assume UDP uploads the signature correctly here, or is that a step I have to redo manually? Help is much appreciated, as we can't find any documentation regarding error codes or further known issues. Cheers, Michael PS: Sandbox testing works without any issues.
