What is the difference between ContentProviders and ContentResolver? I do not want for the SQLite database. I am developing an application for media.

The Content Resolver behaves exactly as its name implies: it accepts requests from clients, and resolves these requests by directing them to the content provider with a distinct authority. To do this, the Content Resolver stores a mapping from authorities to Content Providers.
You can implement as many as you want, as you can see from the documentation here. To register a content provider, you need to add its corresponding <provider> tag in the Android Manifest. In most cases, however, you won't need multiple content providers. One is usually enough, as it can handle multiple tables.
Content providers can help an application manage access to data stored by itself, stored by other apps, and provide a way to share data with other apps. They encapsulate the data, and provide mechanisms for defining data security.
I found some explanation here. In summary
Content Resolver resolves a URI to a specific Content provider.
Content Provider provides an interface to query content.
The way to query a content provider is contentResolverInstance.query(URI,.....)
