Problems with EasyAR (invalid key on Release/Production Mode)

[von-maurus]

Hello!, I have a flutter app with a Unity Easy AR application which requires a Key in order to work. When I build in Debug Mode it works fine, no errors, but the problem is that when I make a build or immediately launch a project on the device in Release-mode , I get an error: Invalid Key. But at the same time, the application package ID and the key itself are 100% correct. This was tested on Android Device.

Steps to reproduce the behavior:

1. Integrate Easy AR in your Unity Project (works fine)
2. Export to Flutter following the steps on this Plugin
3. Test it on debug mode (works fine)
4. Generate a Release APK (fat).
5. Get a an error like: "Invalid Key Get from EasyAR Develop Center (www.easyar.com) -> SD Authorization"

Expected behavior A clear and concise description of what you expected to happen.

Screenshots This is the error shown

Unity (please complete the following information):

• OS: Android
• Version: 2019.4.28.f1

Device version

• Device: All Android devices
• OS: Android
• Version: SDK 24 or later

Additional context The assumptions are the following:

• Is not a Key version problem because I have a Pro Key generated with enhanced features.
• The error prompt by EasyAR is very poor (invalid key message shown in image).
• I'm assuming that an EasyAR library maybe gets eliminated or erased when a Release version is build.
• Maybe the package name changes when a release apk is generated.
• I checked 100% the package names and

If someone has a better way on doing AR apps using Vuforia or EasyAR please share some knowledge because the issues found didn't work for me. Here are some issues related to this bug:

I have the same problem, in debug it works fine while in release it says invalid key. I verified that the application id is the same as the one I entered in the license on the easyar website. I also tried to modify the bundle id in unity but the situation doesn't change.

Anyone know what it could be due to and how to fix it ??
