How to construct PickVisualMediaRequest for ActivityResultLauncher

I am trying to use the Activity Result APIs to handle the picking of a single photo for an app I am developing. I am trying to use one of the predefined contracts to keep things simple. So, I am attempting to use the ActivityResultContracts.PickVisualMedia() contract.

I am setting the Activity Result Launcher up as follows:

private ActivityResultLauncher<PickVisualMediaRequest> pickVisualMediaActivityResultLauncher;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    pickVisualMediaActivityResultLauncher = registerForActivityResult(
            new ActivityResultContracts.PickVisualMedia(),
            this::onPickVisualMediaActivityResult
    );
}

And I am attempting to construct a PickVisualMediaRequest and launch the Activity Result Launcher here:

private void onSelectNewPhotoButtonClick() {
    PickVisualMediaRequest request = new PickVisualMediaRequest.Builder()
            .setMediaType(new ActivityResultContracts.PickVisualMedia.ImageOnly())
            .build();
    pickVisualMediaActivityResultLauncher.launch(request);
}

Issue is that Android Studio is complaining about ActivityResultContracts.PickVisualMedia.ImageOnly() not having proper visibility to be used, even though it is a valid VisualMediaType and the docs imply that it should be used this way:

I can't really find any code samples on this particular scenario. Am I missing something? Does the API have a visibility defect or am I just dumb today?

For me this code from vendor (last sample) is working (but yep, the error is still bothering so I'd like to find stable solution as well).

Actually, I also got the same error but when I executed the code it was compiled and run and worked as expected.

you can refer to the code

pickMedia.launch(new PickVisualMediaRequest.Builder() .setMediaType(ActivityResultContracts.PickVisualMedia.ImageOnly.INSTANCE) .build());

As of March 22, 2023. There is a fix just update androidx.activity:activity to version 1.7.0.

After some help from CommonsWare, I determined that setMediaType() accepts a Kotlin object instance. So, the above bad function I had should be:

private void onSelectNewPhotoButtonClick() {
    ActivityResultContracts.PickVisualMedia.VisualMediaType mediaType = (ActivityResultContracts.PickVisualMedia.VisualMediaType) ActivityResultContracts.PickVisualMedia.ImageOnly.INSTANCE;
    PickVisualMediaRequest request = new PickVisualMediaRequest.Builder()
            .setMediaType(mediaType)
            .build();
    pickVisualMediaActivityResultLauncher.launch(request);
}

Android Studio complains about the type casting, but the code does compile and work as expected. Very bizarre.
