Regression

No

[Android] [iOS] The first use of the "UnityWebRequestAssetBundle" shows "UnityWebRequest.Result.Success" when the AssetBundle is built for a different platform

-

How to reproduce:
1. Open the “ReproProjectFileBundle.zip” project
2. Open the “SampleScene”
3. Build and Run for Android
4. Observe the two texts shown in the applications

Expected result: Both TextFields display “[TEST_ASSET_BUNDLE_REQUEST_ISSUE] Result before accessing downloadHandler.assetBundle DataProcessingError“
Actual result: Top most TextField displays “[TEST_ASSET_BUNDLE_REQUEST_ISSUE] Result before accessing downloadHandler.assetBundle *Success*”, the second one displays “[TEST_ASSET_BUNDLE_REQUEST_ISSUE] Result after accessing downloadHandler.assetBundle DataProcessingError“

Reproducible with: 2022.3.54f1, 6000.0.31f1, 6000.1.0a8
Could not test with: 2021.3.47f1 (JDK issue I couldn’t resolve)

Reproducible environment: macOS 15.1.1 (Intel), Windows 11 (Reporters)
Not reproducible environment: No other environment tested

Reproducible with these devices:
VLNQA00511, Samsung Galaxy S8 (SM-G950F), Android 9, CPU: Exynos 9 Octa 8895, GPU: Mali-G71
VLNQA00518, Google Pixel 4 (Pixel 4), Android 13, CPU: Snapdragon 855 SM8150, GPU: Adreno (TM) 640
VLNQA00107, Huawei Nexus 6P (Nexus 6P), Android 8.1.0, CPU: Snapdragon 810 MSM8994, GPU: Adreno (TM) 430
VLNQA00335, Samsung Galaxy S20+ 5G (SM-G986B), Android 10, CPU: Exynos 990, GPU: Mali-G77
VLNQA00416, iPhone 13 Pro (MLVA3ET/A), CPU: Apple A15 Bionic, GPU: Apple designed, OS: 16.1.1

Note: Cannot test Editor and Standalone are the AssetBundle is built for them and the “UnityWebRequest.result“ will show success, but there is a big chance that it will reproduce

  1. Resolution Note:

    Issue is not present if autoLoadAssetBundle is set to true on download handler:
    https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Networking.DownloadHandlerAssetBundle-autoLoadAssetBundle.html

    Default is false, so asset bundle is only loaded uppon access, hence UnityWebRequest can only report the status of the download part, which has been successful.
