Constructor Detail

AccessToken

public AccessToken(java.lang.String accessToken,
                   java.lang.String applicationId,
                   java.lang.String userId,
                   @Nullable
                   java.util.Collection<java.lang.String> permissions,
                   @Nullable
                   java.util.Collection<java.lang.String> declinedPermissions,
                   @Nullable
                   AccessTokenSource accessTokenSource,
                   @Nullable
                   java.util.Date expirationTime,
                   @Nullable
                   java.util.Date lastRefreshTime)

Creates a new AccessToken using the supplied information from a previously-obtained access token (for instance, from an already-cached access token obtained prior to integration with the Facebook SDK). Note that the caller is asserting that all parameters provided are correct with respect to the access token string; no validation is done to verify they are correct.

Parameters:

accessToken - the access token string obtained from Facebook

applicationId - the ID of the Facebook Application associated with this access token

userId - the id of the user

permissions - the permissions that were requested when the token was obtained (or when it was last reauthorized); may be null if permission set is unknown

declinedPermissions - the permissions that were declined when the token was obtained; may be null if permission set is unknown

accessTokenSource - an enum indicating how the token was originally obtained (in most cases, this will be either AccessTokenSource.FACEBOOK_APPLICATION or AccessTokenSource.WEB_VIEW); if null, FACEBOOK_APPLICATION is assumed.

expirationTime - the expiration date associated with the token; if null, an infinite expiration time is assumed (but will become correct when the token is refreshed)

lastRefreshTime - the last time the token was refreshed (or when it was first obtained); if null, the current time is used.

Method Detail

getCurrentAccessToken

public static AccessToken getCurrentAccessToken()

Getter for the access token that is current for the application.

Returns:

The access token that is current for the application.

setCurrentAccessToken

public static void setCurrentAccessToken(AccessToken accessToken)

Setter for the access token that is current for the application.

Parameters:

accessToken - The access token to set.

refreshCurrentAccessTokenAsync

public static void refreshCurrentAccessTokenAsync()

Updates the current access token with up to date permissions, and extends the expiration date, if extension is possible.

refreshCurrentAccessTokenAsync

public static void refreshCurrentAccessTokenAsync(AccessToken.AccessTokenRefreshCallback callback)

Updates the current access token with up to date permissions, and extends the expiration date, if extension is possible.

Parameters:

callback -

getToken

public java.lang.String getToken()

Gets the string representing the access token.

Returns:

the string representing the access token

getExpires

public java.util.Date getExpires()

Gets the date at which the access token expires.

Returns:

the expiration date of the token

getPermissions

public java.util.Set<java.lang.String> getPermissions()

Gets the list of permissions associated with this access token. Note that the most up-to-date list of permissions is maintained by Facebook, so this list may be outdated if permissions have been added or removed since the time the AccessToken object was created. For more information on permissions, see https://developers.facebook.com/docs/reference/login/#permissions.

Returns:

a read-only list of strings representing the permissions granted via this access token

getDeclinedPermissions

public java.util.Set<java.lang.String> getDeclinedPermissions()

Gets the list of permissions declined by the user with this access token. It represents the entire set of permissions that have been requested and declined. Note that the most up-to-date list of permissions is maintained by Facebook, so this list may be outdated if permissions have been granted or declined since the last time an AccessToken object was created.

Returns:

a read-only list of strings representing the permissions declined by the user

getSource

public AccessTokenSource getSource()

Gets the AccessTokenSource indicating how this access token was obtained.

Returns:

the enum indicating how the access token was obtained

getLastRefresh

public java.util.Date getLastRefresh()

Gets the date at which the token was last refreshed. Since tokens expire, the Facebook SDK will attempt to renew them periodically.

Returns:

the date at which this token was last refreshed

getApplicationId

public java.lang.String getApplicationId()

Gets the ID of the Facebook Application associated with this access token.

Returns:

the application ID

getUserId

public java.lang.String getUserId()

Returns the user id for this access token.

Returns:

The user id for this access token.
