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)

Answer 1

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.
