Command line build not working for Oculus Go Project because it can't find Android SDK

Hi all,

I'm currently working on automating the build pipeline for an Oculus Go project. (I'm not using the Unity build services).

I'm making use of the Azure Devops Unity Build extension that executes a headless build of my Unity project for android:



When I build this project using the tasks it fails after a while. When I open the project using the Unity Editor it will actually build an APK.

I then compared the Editor.log output for the Azure DevOps build and the Editor.log for the manual build. These are the differences:

Azure DevOps build (Editor.log):

So basically the 'command line' build isn't able to find the Android SDK. I did configure this in the UI though.

Does anyone have an idea if it's possible to either fix this issue or be able to automatically provide the Android SDK location to the Unity build process?

 

Did you ever find a fix for this @devedse ? Struggling with the same on anything pre. 2019

 

Old thread, but I'll answer anyway since I encountered this.

Set the environment variable of ANDROID_SDK_ROOT to your root directory (in the original example - C:\Users\digitalstudio\AppData\Local\Android\sdk) and do this with a pipeline variable.

For me for some reason a manual run would detect the SDK just fine, but a pipeline task would say invalid path unless this env var was set.
