/**
* The contract between the voicemail provider and applications. Contains
* definitions for the supported URIs and columns.
*
* <P>The content providers exposes two tables through this interface:
* <ul>
* <li> Voicemails table: This stores the actual voicemail records. The
* columns and URIs for accessing this table are defined by the
* {@link Voicemails} class.
* </li>
* <li> Status table: This provides a way for the voicemail source application
* to convey its current state to the system. The columns and URIS for
* accessing this table are defined by the {@link Status} class.
* </li>
* </ul>
*
* <P> The minimum permission needed to access this content provider is
* {@link Manifest.permission#ADD_VOICEMAIL}
*
* <P>Voicemails are inserted by what is called as a "voicemail source"
* application, which is responsible for syncing voicemail data between a remote
* server and the local voicemail content provider. "voicemail source"
* application should always set the {@link #PARAM_KEY_SOURCE_PACKAGE} in the
* URI to identify its package.
*
* <P>In addition to the {@link ContentObserver} notifications the voicemail
* provider also generates broadcast intents to notify change for applications
* that are not active and therefore cannot listen to ContentObserver
* notifications. Broadcast intents with following actions are generated:
* <ul>
* <li> {@link #ACTION_NEW_VOICEMAIL} is generated for each new voicemail
* inserted.
* </li>
* <li> {@link Intent#ACTION_PROVIDER_CHANGED} is generated for any change
* made into the database, including new voicemail.
* </li>
* </ul>
