Constants
CREATEDIndicates that the Session has not yet been opened and has no cached
token. Opening a Session in this state will involve user interaction.
public static final SessionState CREATEDCREATED_TOKEN_LOADED
Indicates that the Session has not yet been opened and has a cached
token. Opening a Session in this state will not involve user interaction.
If you are using Session from an Android Service, you must provide a
TokenCachingStrategy implementation that contains a valid token to the Session
constructor. The resulting Session will be created in this state, and you
can then safely call open, passing null for the Activity.
public static final SessionState CREATED_TOKEN_LOADEDOPENINGIndicates that the Session is in the process of opening.
public static final SessionState OPENINGOPENEDIndicates that the Session is opened. In this state, the Session may be
used with a Request.
public static final SessionState OPENEDOPENED_TOKEN_UPDATED
Indicates that the Session is opened and that the token has changed. In
this state, the Session may be used with Request.
Every time the token is updated, StatusCallback is called with this value.
public static final SessionState OPENED_TOKEN_UPDATEDCLOSED_LOGIN_FAILEDIndicates that the Session is closed, and that it was not closed
normally. Typically this means that the open call failed, and the
Exception parameter to StatusCallback will
be non-null.
public static final SessionState CLOSED_LOGIN_FAILEDCLOSEDIndicates that the Session was closed normally.
public static final SessionState CLOSED
