Unity3D & Google Play Store - Invalid key on device with Android App Bundle

Question

Hi, we have developed an app using EasyAR 3.0 with IL2CPP on Google Play Store and is 64-bit compliance. However, the app has "Invalid Key" error on the newer phones like Samsung S9+, Huawei Mate 20 Pro but the app work fine in the older phone like Samsung J7, Xiaomi 6. Is there any insight on this issue? It is an urgent matter as the client needs this app to be functionally workable asap. Thank you.

Answer 1

1. Please make sure the License Key is the same as the official website.

2. And if you change the Package Name or Bundle ID in official website, the License Key will change accordingly.

Comments

We doubt that it is due to the License Key / Package Name / Bundle ID problem. Because when we re-upload the app with .apk file instead of .aab with IL2CPP (ARMv7 and ARM64 are also checked) in unity. The invalid key error is gone. Maybe EasyAR's development team can look into these issues in depth. Or in case we missed any vital steps to be done before we can successfully upload the project to Google Play Store as .aab just let us know.

At present, EasyAR doesn't support building with aab. And the problem comes from Unity.   It is recommended that the project exports AS from Unity.

"It is recommended that the project exports AS from Unity".
I cant understand this statement. Mind to elaborate on this? Or any link for information on this? Thanks in advance.

I found this solution last time and had solved my problem. Thanks for your response.

Answer 2

For anyone who also experiences this issue, we currently solved it on Samsung S9+ by re-upload the app with .apk file instead of .aab file (In Unity3D with Scripting Bankend  = IL2CPP; ARMv7 and ARM64 ticked).

Comments

Also it is a good idea to activate "Split APK by target architecture" to split the app in 2 apks for each platform, this way the download size for the user will be smaller, because it doesn't include the same app twice for each platform. Even if it says it is experimental we didn't had any problems.
