[SOLVED]Caching.ClearOtherCachedVersions not working

This is my c# code for clearing cache，all Caching.ClearOtherCachedVersions invoking return true, but clear nothing. Is that because of I request assetbundle with UnityWebRequestAssetBundle.GetAssetBundle(Uri uri, uint version, uint crc) not UnityWebRequestAssetBundle.GetAssetBundle(string uri, Hash128 hash, uint crc = 0)?

Code (CSharp):

1. public void ClearOtherCachedVersions(Action<long, long> progressCb = null) {
2.     if (manifest == null) {
3.         progressCb?.Invoke(0, 0);
4.         return;
5.     }
6.     var assetBundles = manifest.GetAllAssetBundles();
7.     for (var i = 0; i < assetBundles.Length; ++i) {
8.         var clearCache = Caching.ClearOtherCachedVersions(assetBundles[i], manifest.GetAssetBundleHash(assetBundles[i]));
9.         Debug.Log(clearCache
10.             ? $"Caching.ClearOtherCachedVersions() successfully, assetBundle name {assetBundles[i]}"
11.             : $"Caching.ClearOtherCachedVersions() failed, assetBundle name {assetBundles[i]}");
12.         progressCb?.Invoke(i + 1, assetBundles.Length);
13.     }
14. }

 

I am trying to use UnityWebRequestAssetBundle.GetAssetBundle(string uri, Hash128 hash, uint crc = 0) to get asset bundle, but when I try to get hash of asset bundle for manifest with following code, it always return "00000000000000000000000000000000“，I wonder why?

Code (CSharp):

1. BuildPipeline.GetHashForAssetBundle("path/to/assetbundle/output/path/Android", out var hash1);
2. Debug.Log(hash1.ToString());

 

Code (CSharp):

1. Caching.ClearOtherCachedVersions("assetBundleName", new Hash128(0U, 0U, 0U, verInfo.crc))

This code clear nothing too.

 

Well, it is working now, the first parameter of Caching.ClearOtherCachedVersions should not contain any path of assetbundle, it must be only file name of assetbundle, otherwise, it will fail.
