[Android] Build fails when there are 680 or more files in the Streaming Assets folder



Reproduction steps:
1. Download and open the user-submitted project ""
2. Build the project

Expected result: Build is successful
Actual result: Build fails

Reproduces on: 2020.1.0b14, 2020.1.6f1

Does not reproduce on: 2019.4.11f1, 2020.1.0b13, 2020.2.0a1, 2020.2.0b3

Error message:
> A failure occurred while executing$ActionFacade

UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

Does not reproduce on iOS
This is a problem outside of Unity, reported to Android Studio:

A workaround would be to use custom Gradle files and specify the file extensions. By default we specify few extensions and list all the files from streaming assets. Instead of listing streaming assets you can specify the file extensions. The downside with that is that all files with such extension will be uncompressed including those outside of streaming assets.

    I have the same problem with Unity 2020.3.24f1.
    below is my solution
    in \2020.3.24f1c1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\
    find launcherTemplate.gradle mainTemplate.gradle files ,and
    origion content:
    aaptOptions {
    noCompress = ['.ress', '.resource', '.obb'] + unityStreamingAssets.tokenize(', ')
    my changed:
    aaptOptions {
    noCompress = ['.ress', '.resource', '.obb', ''] + unityStreamingAssets.tokenize(', ')
    add , '' after '.obb'

    I'm doubting Unity's "Fixed" updates.

    Version 2020.3.13f1 is not apparently available to download. And, we are using Unity 2020.1.10f1 and getting this error
