Hi,

I am not able to create any file using "System.IO.File.Create" API at following location with my app targeted to Android 11 ( Target SDK API 30).

  • /storage/emulated/0/Documents

The API which I use in my application to get above path is "Android.OS.Environment.GetExternalStoragePublicDirectory (Android.OS.Environment.DirectoryDocuments).Path".

I have got to know that with Android 11 their is Scoped Storage compulsory to be used. But then I want to know how can we create files out of app specific folder (Internal shared storage\Android\data).

The Exception I am getting while creating file is below:

  • Could not create file "/storage/emulated/0/Documents/abc.txt". File already exists.

But I think the above exception thrown is not real one.

The Xamarin Forms version used : 4.8.0.1560.
Visual Studio Version: VS2019 16.9.0

Any help or guidance on this is appreciated. Thanks in Advance.

Thanks.

    Hello,

    Welcome to our Microsoft Q&A platform!

    When we check document getExternalStoragePublicDirectory,we will find that

    So, you can access content stored on shared/external storage by migrating to alternatives such as Context#getExternalFilesDir(String), MediaStore, or Intent#ACTION_OPEN_DOCUMENT.

    And there is a article about this, you can check it here: Android 11 Scoped Storage - Saving Files To Shared Storage .

    Best Regards,

    Jessie Zhang
