No virtual method loadThumbnail() in class ContentResolver or its super classes

When I use public @NonNull Bitmap loadThumbnail(@NonNull Uri uri, @NonNull Size size,@Nullable CancellationSignal signal) method ,

it is always showing this error

Is there is any other way to solve this error ?

My code looks like this :

val bitmap = applicationContext.contentResolver.loadThumbnail(uri,Size(5,5),null)
thumbnail_image_view.setImageBitmap(bitmap)
screenshot_image_view.setImageBitmap(bitmap)

The method loadThumbnail() was only added in API level 29 that Android 10.0 so it won't work in lower versions. However, you can use image loader libraries like picasso or glide with the uri.

Have you tried passing the context of activity or fragment instead of application context ?
