Hello!
I have built my game’s asset management architecture around Addressables and I am currently trying to get Android Asset Packs and Play Asset Delivery up and running, to minimize app size for Google Play and offload optional content into downloadable Asset Packs.
I believe I have configured everything correctly in Unity, but honestly all the settings and lack of documentation confuses me a bit. Also, this is the first time I’m setting up PAD, so I might have gotten something wrong.
When testing, I am uploading the aab-file to Google Play Console on an internal testing track and downloading it via Google Play to ensure a real environment.
All the Addressable groups configured as install-time seem to work fine, but fast-follow and on-demand does not. Running Logcat on the build from Google Play consistently produces this error:
2024/12/16 16:57:15.661 5775 5824 Error Unity InvalidOperationException: PlayAssetDelivery AssetPackManager API is not available! Make sure your gradle project includes "com.google.android.play:asset-delivery" dependency.
From what I could gather online, Unity is supposed to include this dependency in the build automatically. However, I also tried creating a custom mainTemplate.gradle including this pack as a dependency but the error persisted.
Currently on Unity 6000.0.23 and the only thing I can think of to try is building with a more recent Unity version. I will report back if that works.
Totally stuck here and hope someone can point me in the right direction!
Nope, the error is still there in Unity 6000.0.31f.

Finally figured it out. It was caused by minification, which must have stripped some important code. Unchecking Project Settings - Player - Publishing Settings - Minify - Release fixed the problem 
It works! Oh my god I was struggling with this same issue for a few months, you’re a savior. This also worked for Unity 6000.0.24
