35/**
36 * The contract between the voicemail provider and applications. Contains
37 * definitions for the supported URIs and columns.
38 *
39 * <P>The content providers exposes two tables through this interface:
40 * <ul>
41 *   <li> Voicemails table: This stores the actual voicemail records. The
42 *   columns and URIs for accessing this table are defined by the
43 *   {@link Voicemails} class.
44 *   </li>
45 *   <li> Status table: This provides a way for the voicemail source application
46 *   to convey its current state to the system. The columns and URIS for
47 *   accessing this table are defined by the {@link Status} class.
48 *   </li>
49 * </ul>
50 *
51 * <P> The minimum permission needed to access this content provider is
52 * {@link android.Manifest.permission#ADD_VOICEMAIL} or carrier privileges (see
53 * {@link android.telephony.TelephonyManager#hasCarrierPrivileges}).
54 *
55 * <P>Voicemails are inserted by what is called as a "voicemail source"
56 * application, which is responsible for syncing voicemail data between a remote
57 * server and the local voicemail content provider. "voicemail source"
58 * application should always set the {@link #PARAM_KEY_SOURCE_PACKAGE} in the
59 * URI to identify its package.
60 *
61 * <P>In addition to the {@link ContentObserver} notifications the voicemail
62 * provider also generates broadcast intents to notify change for applications
63 * that are not active and therefore cannot listen to ContentObserver
64 * notifications. Broadcast intents with following actions are generated:
65 * <ul>
66 *   <li> {@link #ACTION_NEW_VOICEMAIL} is generated for each new voicemail
67 *   inserted.
68 *   </li>
69 *   <li> {@link Intent#ACTION_PROVIDER_CHANGED} is generated for any change
70 *    made into the database, including new voicemail.
71 *   </li>
72 * </ul>
