Bug Add an old Android SDK

Hi !

I use the Unity Editor 2019.4.25f1 with Android SDK 29 API by default. However I need to use the Android SDK 28 API. I downloaded the platform with the SDK Manager but the compiler gives me the error message "Android resource linking failed". What can I do to properly have the SDK ?

Thanks a lot for your answers !

I switched to API 28 in Player Settings in Unity. What is the name of the gradle file ? How can I modify gradle file ?

 

I put my errors below. I don't understand where the problem come from...

 

I generated with Player Settings a mainTemplate.gradle file and modified it. But the error is still here.

The content of my gradle file :

It's strange because I have a NDK and I use it with API 29...

 

Hi ! I added a "platforms" folder in my NDK directory. However, the program still doesn't compile and I don't understand why... This is my error message :

I found it. I built my project on Android Studio and the compiler give me an error in a generated manifest.xml...

Code (CSharp):

1. Android resource linking failed
2. C:\Users\lilia\OneDrive\Documents\Projets\Exported\launcher\build\intermediates\merged_manifests\debug\AndroidManifest.xml:56: error: attribute android:requestLegacyExternalStorage not found.
3. error: failed processing manifest.

I found the same error in the console of Unity :

Code (CSharp):

1. FAILURE: Build failed with an exception.
2.  
3. * What went wrong:
4. Execution failed for task ':launcher:processReleaseResources'.
5. > Android resource linking failed
6.   C:\Users\lilia\OneDrive\Documents\Projets\Unity\Nouveau dossier\FitImmersion-Unity\Temp\gradleOut\launcher\build\intermediates\merged_manifests\release\AndroidManifest.xml:56: AAPT: error: attribute android:requestLegacyExternalStorage not found.
7.      
8.   error: failed processing manifest.

After reading this I resolved my issue by upgrading to API 29 in Player > Settings for Android > Other Settings > Android 10.0 (API level 29). When prompted to update the required Android SDK level, I let it update.
