[Xamarin.Android] API-31: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///storage/emulated/0/Pictures/MyApplication/TargetFile.html typ=text/html flg=0x50000081 }

Question

Hello there,

I found error on Android-12 or API-31.

"No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///storage/emulated/0/Pictures/MyApplication/TargetFile.html typ=text/html flg=0x50000081 }"

Normally, I run application on API 27 and it can open file to preview.

This is my code.
[url] = file:///storage/emulated/0/Pictures/MyApplication/TargetFile.html
[mimeType] = text/html

using Android.Content;  
using Android.Net;  
public static void OpenUrl(string url, string mimeType = null) {  
     Uri uri = Uri.Parse(url);  
     Intent intent = new Intent(Intent.ActionView);   
     intent.SetFlags(ActivityFlags.NoHistory|ActivityFlags.NewTask|ActivityFlags.GrantReadUriPermission|ActivityFlags.GrantPrefixUriPermission);  
     if (mimeType == null) intent.SetData(uri);  
     else intent.SetDataAndType(uri, mimeType);  
     Android.App.Application.Context.StartActivity(intent);  
}  

Can someone help me to solve this problem?
I thank you for the answer in advance.

P.S. My main language isn't English. If the words're used incorrectly, I apologize.

Hello,​

Is this TargetFile.html store in the public path? If so, you cannot access the public folder path for Android 11 or later, Please see this storage limitation
