Camera MediaPicker throws error about write external storage on api 31

williambuchanan2 commented 1 year ago

Description

Using the camera in Maui doesn't seem to work due to permission issues. Using MediaPicker example from the Microsoft documents doesn’t work. Throws error as it tries to access storage.

Error: Microsoft.Maui.ApplicationModel.PermissionException: 'StorageWrite permission was not granted: Denied'

Note that if I don't request StorageWrite permission I get the following error:

Microsoft.Maui.ApplicationModel.PermissionException: 'You need to declare using the permission: android.permission.WRITE_EXTERNAL_STORAGE in your AndroidManifest.xml'

So, bit of a catch 22 situation...

Steps to Reproduce

Do exactly what this page shows:

https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/device-media/picker

Android.Manifest entries:

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.ACTION_OPEN_DOCUMENT" />
    <uses-permission android:name="android.permission.ACTION_OPEN_DOCUMENT_TREE" />

    <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
    <uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />
    <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />

    <!-- Required to maintain app compatibility. -->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>

    <queries>
        <intent>
            <action android:name="android.media.action.IMAGE_CAPTURE" />
        </intent>
    </queries>

Code:

   private async void TakePhotoPressed()
    {
        MediaPickerOptions options = new MediaPickerOptions();
        options.Title = "Add Attachment";

        FileResult result = await MediaPicker.Default.CapturePhotoAsync(options);
        ...
    }

We fixed it a few weeks ago and backported to net7, unfortunately it missed the release so will go out with the next servicing release.

One workaround is to set your app to target one version back: https://github.com/dotnet/maui/issues/11275#issuecomment-1400211776

Very unfortunate to not get this out sooner, I know.
