In my project I need to use IContentService, and I've used the right import (import android.content.IContentService) and yet android studio tells me 'Cannot resolve symbol IContentService'.
I know IContentService is an actual class, because it is used in ContentResolver.getContentService();
Anyone know how I can get this import to work?
You cannot use this class directly.
You can see in the source code (e.g. here for Marshmallow) that this class is tagged with the @hide
annotation.
The class can only be used by reflection as shown here (with all it's disadvantages).
BTW: ContentResolver.getContentService()
is also a hidden method (see here).
