VoicemailContract

extends Object
java.lang.Object
   ↳ android.provider.VoicemailContract

Class Overview

The contract between the voicemail provider and applications. Contains definitions for the supported URIs and columns.

The content providers exposes two tables through this interface:

  • Voicemails table: This stores the actual voicemail records. The columns and URIs for accessing this table are defined by the VoicemailContract.Voicemails class.
  • 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 VoicemailContract.Status class.

The minimum permission needed to access this content provider is ADD_VOICEMAIL

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 PARAM_KEY_SOURCE_PACKAGE in the URI to identify its package.

In addition to the 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:
