[ANDROID] Requesting Read-Write External Storage in .net 7 not working

[tataelm]

Description

"android.permission.READ_EXTERNAL_STORAGE" and "android.permission.WRITE_EXTERNAL_STORAGE" can't be requested. I have tried adding it under AndroidManifest.xml and adding it as assembly under MainActivity.cs but no use.

Besides "ShouldShowRationale" not getting triggered, I can't change the permissions manually neither because there is none.

Steps to Reproduce

1. Create a brand new project with .net 7.
2. Add these under AndroidManifest.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

3. Add a method on main page and trigger it via button click

 public async Task CheckForPermissions()
    {               
        var status_write = await Permissions.CheckStatusAsync<Permissions.StorageWrite>();
        var status_read = await Permissions.CheckStatusAsync<Permissions.StorageRead>();

        if (Permissions.ShouldShowRationale<Permissions.StorageWrite>())
        {
            // just testing
        }

        if (Permissions.ShouldShowRationale<Permissions.StorageRead>())
        {
            // just testing
        }

        status_write = await Permissions.RequestAsync<Permissions.StorageWrite>();
        status_read = await Permissions.RequestAsync<Permissions.StorageRead>();

        if (status_write != PermissionStatus.Granted)
        {
            // still not granted
        }

        // forward user to settings so they can grant permission
        AppInfo.Current.ShowSettingsUI();
    }

4. You will be forwarded to application settings and you won't find any permission requests.

There is this issue: #12857
And this PR: #12766

We added this code:

if (!OperatingSystem.IsAndroidVersionAtLeast(33))
    await Permissions.EnsureGrantedAsync<Permissions.StorageWrite>();

Maybe we need to make the request do nothing on 33+ and just return granted always?

In Android 13+ android.permission.WRITE_EXTERNAL_STORAGE no longer exists, and requesting it always returns Denied.

Having the same issue, very annoying. Was hoping to let users backup their database to wherever they wanted but seems to be near impossible to get working on .NET 7 against API 33 at the moment.

Hi @tataelm , I know this may not be ideal for you, but I think this has been fixed in .NET 8.
Did you give it a try?

[MattePozzy]

Android 14 .net 8
PermissionStatus storageStatus = await Permissions.CheckStatusAsync<Permissions.StorageWrite>();
return always false.
In manifest is
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />.

This is still an issue - it returns denied for both StorageRead and StorageWrite on Android 14. Though on Android now accessing the file system should mean you go through Storage Access Framework and and the MediaStore (which require platform specific setup that we've had to implement ourselves)

This is an issue for us in a migration from Xamarin forms and is becoming a bit of a showstopper. We've followed all the recommendations for the manifest. Taking/uploading images and videos kind of works (we are also seeing a significantly awful degradation in performance for encrypted files but that's a different story although who knows if it's related or not), but as soon as a user tries to upload from "File manager" (and not pics/vids):
