Content Provider Helper
This helper is a frontend to query installed content providers. Android's content providers are similar to database tables.: They have a name (aka "content:" uri), columns and they can be queried similar to SQL.
Android uses content-providers as API to manage global accessable data (i.e. images, address book, text messages, ...).
Forked from jenzz-s ContentProviderHelper which is not maintained anymore.
App permissions are set generously to provide maximum compatibility.
