Diese Klasse ist in der neuesten Version des SDKs nicht mehr verfügbar.
Es ist eine neuere Version dieser Klasse verfügbar. Sieh sie dir an mit der aktuellsten Version.

THIS CLASS SHOULD BE CONSIDERED DEPRECATED.

All public members of this class are intentionally deprecated. New code should instead use Session to manage session state, Request to make API requests, and WebDialog to make dialog requests.

Adding @Deprecated to this class causes warnings in other deprecated classes that reference this one. That is the only reason this entire class is not deprecated.

Erweiterungen:	`Object`
Package:	`android`

Instance-Methoden

authorize(Activity, DialogListener)

Default authorize method. Grants only basic permissions.

See authorize() below for @params.

This method is deprecated. See Facebook and Session for more info.

public void authorize(Activity activity, DialogListener listener)

Parameter	Beschreibung
`activity`
`listener`

authorize(Activity, String, DialogListener)

Authorize method that grants custom permissions.

See authorize() below for @params.

This method is deprecated. See Facebook and Session for more info.

public void authorize(Activity activity, String permissions, DialogListener listener)

Parameter	Beschreibung
`activity`
`permissions`
`listener`

authorize(Activity, String, int, DialogListener)

Full authorize method.

Starts either an Activity or a dialog which prompts the user to log in to Facebook and grant the requested permissions to the given application.

This method will, when possible, use Facebook's single sign-on for Android to obtain an access token. This involves proxying a call through the Facebook for Android stand-alone application, which will handle the authentication flow, and return an OAuth access token for making API calls.

Because this process will not be available for all users, if single sign-on is not possible, this method will automatically fall back to the OAuth 2.0 User-Agent flow. In this flow, the user credentials are handled by Facebook in an embedded WebView, not by the client application. As such, the dialog makes a network request and renders HTML content rather than a native UI. The access token is retrieved from a redirect to a special URL that the WebView handles.

Note that User credentials could be handled natively using the OAuth 2.0 Username and Password Flow, but this is not supported by this SDK.

See http://developers.facebook.com/docs/authentication/ and http://wiki.oauth.net/OAuth-2 for more details.

Note that this method is asynchronous and the callback will be invoked in the original calling thread (not in a background thread).

Also note that requests may be made to the API without calling authorize first, in which case only public information is returned.

IMPORTANT: Note that single sign-on authentication will not function correctly if you do not include a call to the authorizeCallback() method in your onActivityResult() function! Please see below for more information. single sign-on may be disabled by passing FORCE_DIALOG_AUTH as the activityCode parameter in your call to authorize().

This method is deprecated. See Facebook and Session for more info.

public void authorize(Activity activity, String permissions, int activityCode, DialogListener listener)

Parameter	Beschreibung
`activity`	The Android activity in which we want to display the authorization dialog.
`permissions`	A list of permissions required for this application: e.g. "read_stream", "publish_stream", "offline_access", etc. see http://developers.facebook.com/docs/authentication/permissions This parameter should not be null -- if you do not require any permissions, then pass in an empty String array.
`activityCode`	Single sign-on requires an activity result to be called back to the client application -- if you are waiting on other activities to return data, pass a custom activity code here to avoid collisions. If you would like to force the use of legacy dialog-based authorization, pass FORCE_DIALOG_AUTH for this parameter. Otherwise just omit this parameter and Facebook will use a suitable default. See http://developer.android.com/reference/android/ app/Activity.html for more information.
`listener`	Callback interface for notifying the calling application when the authentication dialog has completed, failed, or been canceled.

authorizeCallback(int, int, Intent)

IMPORTANT: If you are using the deprecated authorize() method, this method must be invoked at the top of the calling activity's onActivityResult() function or Facebook authentication will not function properly!

If your calling activity does not currently implement onActivityResult(), you must implement it and include a call to this method if you intend to use the authorize() method in this SDK.

For more information, see http://developer.android.com/reference/android/app/ Activity.html#onActivityResult(int, int, android.content.Intent)

This method is deprecated. See Facebook and Session for more info.

public void authorizeCallback(int requestCode, int resultCode, Intent data)

Parameter	Beschreibung
`requestCode`
`resultCode`
`data`

extendAccessToken(Context, ServiceListener)

Refresh OAuth access token method. Binds to Facebook for Android stand-alone application application to refresh the access token. This method tries to connect to the Facebook App which will handle the authentication flow, and return a new OAuth access token. This method will automatically replace the old token with a new one. Note that this method is asynchronous and the callback will be invoked in the original calling thread (not in a background thread).

This method is deprecated. See Facebook and Session for more info.

public boolean extendAccessToken(Context context, ServiceListener serviceListener)

Parameter	Beschreibung
`context`	The Android Context that will be used to bind to the Facebook RefreshToken Service
`serviceListener`	Callback interface for notifying the calling application when the refresh request has completed or failed (can be null). In case of a success a new token can be found inside the result Bundle under Facebook.ACCESS_TOKEN key.

Returns

True if the binding to the RefreshToken Service was created

extendAccessTokenIfNeeded(Context, ServiceListener)

Calls extendAccessToken if shouldExtendAccessToken returns true.

This method is deprecated. See Facebook and Session for more info.

public boolean extendAccessTokenIfNeeded(Context context, ServiceListener serviceListener)

Parameter	Beschreibung
`context`
`serviceListener`

Returns

The same value as extendAccessToken if the the token requires refreshing, true otherwise

shouldExtendAccessToken()

Check if the access token requires refreshing.

This method is deprecated. See Facebook and Session for more info.

public boolean shouldExtendAccessToken()

Returns

True if the last time a new token was obtained was over 24 hours ago.

logout(Context)

Invalidate the current user session by removing the access token in memory, clearing the browser cookie, and calling auth.expireSession through the API.

Note that this method blocks waiting for a network response, so do not call it in a UI thread.

This method is deprecated. See Facebook and Session for more info.

public String logout(Context context)

Parameter	Beschreibung
`context`	The Android context in which the logout should be called: it should be the same context in which the login occurred in order to clear any stored cookies

Returns

JSON string representation of the auth.expireSession response ("true" if successful)

request(Bundle)

Make a request to Facebook's old (pre-graph) API with the given parameters. One of the parameter keys must be "method" and its value should be a valid REST server API method.

See http://developers.facebook.com/docs/reference/rest/

Note that this method blocks waiting for a network response, so do not call it in a UI thread.

Example: Bundle parameters = new Bundle(); parameters.putString("method", "auth.expireSession"); String response = request(parameters);

This method is deprecated. See Facebook and Request for more info.

public String request(Bundle parameters)
