App works in Unity but not on Android

Question

I`m using the EasyAR Sense 4.3 Unity Plugin in combination with Unity 2019.4.28f1.

My ImageTargets are perfectly detected by the ImageTracker in the Unity GameView. But, when I export my application to an Android Device, the App starts up, but it doesn’t detect any ImageTarget. 

I use the following build settings in Unity:

• Graphics APIs: OpenGLES2 (Auto Graphics API = Off) - changing to OpenGLES3 leads to the same problem
• Mutithreaded Rendering = Off
• Minimum API level = 26; Maximum API level = 30
• Scripting Backend = IL2CPP
• ARCore SDK is set to "optional"
• ARCore for Android 11 is activated in the EasyAR Settings
• Gradle is updated to 5.6.4 

The application was tested on an virtual device via AndroidStudio (Google Pixel with API 30)

I get no error message in Unity.

I hope someone can help me!

Thanks in advance.

Answer 1

1. Does the sample work?

2. What about adb logcat?

3. See if https://answers.easyar.com/17203 helps if you see "Exception: invalid buffer" in logcat output.

Answer 2

I have the same problem. I`m using the EasyAR Sense 4.5 Unity Plugin in combination with Unity 2020.3.30f1.

Have you solved this problem?
