A Fragment that displays a Login/Logout button as well as the user's profile picture and name when logged in.
This Fragment will create and use the active session upon construction if it has the available data (if the app ID is specified in the manifest). It will also open the active session if it does not require user interaction (i.e. if the session is in the SessionState.CREATED_TOKEN_LOADED state. Developers can override the use of the active session by calling the UserSettingsFragment.setSession(com.facebook.Session) method.

protected final List getSessionPermissions() openSession()Opens a new session. This method will use the application id from the associated meta-data value and an empty list of permissions.
protected final void openSession() openSessionForRead(String, List)Opens a new session with read permissions. If either applicationID or permissions is null, this method will default to using the values from the associated meta-data value and an empty list respectively.
protected final void openSessionForRead(String applicationId, List permissions) | المعلمة | الوصف |
|---|---|
applicationId | The applicationID, can be null |
permissions | The permissions list, can be null |
openSessionForRead(String, List, SessionLoginBehavior, int)Opens a new session with read permissions. If either applicationID or permissions is null, this method will default to using the values from the associated meta-data value and an empty list respectively.

applicationId | The applicationID, can be null |
permissions | The permissions list, can be null |
behavior | The login behavior to use with the session |
activityCode | The activity code to use for the SSO activity |
openSessionForPublish(String, List)Opens a new session with publish permissions. If either applicationID is null, this method will default to using the value from the associated meta-data value. The permissions list cannot be null.
protected final void openSessionForPublish(String applicationId, List permissions) | المعلمة | الوصف |

setDefaultAudience(SessionDefaultAudience)Sets the default audience to use when the session is opened. This value is only useful when specifying write permissions for the native login dialog.
public void setDefaultAudience(SessionDefaultAudience defaultAudience) | المعلمة | الوصف |
|---|---|
defaultAudience | The default audience value to use |
getDefaultAudience()Gets the default audience to use when the session is opened. This value is only useful when specifying write permissions for the native login dialog.
public SessionDefaultAudience getDefaultAudience() setReadPermissions(List)Set the permissions to use when the session is opened. The permissions here can only be read permissions. If any publish permissions are included, the login attempt by the user will fail. The LoginButton can only be associated with either read permissions or publish permissions, but not both. Calling both setReadPermissions and setPublishPermissions on the same instance of LoginButton will result in an exception being thrown unless clearPermissions is called in between.
This method is only meaningful if called before the session is open. If this is called after the session is opened, and the list of permissions passed in is not a subset of the permissions granted during the authorization, it will log an error.
Since the session can be automatically opened when the UserSettingsFragment is constructed, it's important to always pass in a consistent set of permissions to this method, or manage the setting of permissions outside of the LoginButton class altogether (by managing the session explicitly).
