Question

The documentation on Android content providers describes using a ContentResolver, obtained from getContentResolver(), to access the content.

Answer 1

Ok, but be aware that it works only when ContentProvider running in this same process as Activity.

Note from documentation for method getLocalContentProvider():

If the ContentProvider is running in a different process then null will be returned. This can be used if you know you are running in the same process as a provider, and want to get direct access to its implementation details.
