How to retrieve facebook user’s friendlist
The newer Graph API changes the API paradigm from a method-oriented way of reading and writing data to and from Facebook to a new way that uses objects think user profiles, friends, posts, photos, likes, and so on and their relationships or connections with each other. This approach simplifies the Facebook API and makes it more consistent when working with objects. Both the Graph and the REST APIs are applicable to mobile applications, both native and mobile web applications, including mobile web content within native applications through the use of WebViews.
With the Graph API, you can retrieve an object, delete an object, and publish objects. Facebook defines a large number of permissions that you can read at the Extended Permissions page see Related links. It does so by providing six Java classes. The Facebook SDK for Android also brings a couple of useful examples that you can use as a baseline for your own applications.
Of special interest are the core Facebook class and the Facebook Dialog class, which I cover in more detail next. The core Facebook class encapsulates methods to authorize the user, create Facebook dialogs, make API requests, log out the user, and get or set access and session information and status.
The dialog is central to the way the SDK operates. The SDK provides two methods to authenticate, one that is referred to as single-sign on which uses, if installed, the native Facebook application dialogs, and the default WebView approach to dialogs. In this article, I will focus on the WebView approach. The rest of the SDK classes are helper classes used to encapsulate error information or provide useful utilities used throughout the SDK. You have to download and install Eclipse or your favorite IDE.
In addition, you must install the Android SDK. Download the SDK source, and extract it into your working directory. Create the project from the existing source and point to the extracted source directory see Download for the source code. This method performs a basic check to make sure that the App ID is set before proceeding, initializes the UI resources, and initializes the Facebook session instance see Initializing the application. The rest of the application flow is triggered by UI interactions through the menu items.
As the user selects a menu item, the application performs the appropriate action. The following listing shows how the menu items are handled. Creating the menu shows how to instantiate the menu by deflating its XML definition. The application uses a number of callbacks to handle the state of each asynchronous call.
The SampleApp defines a callback to handle the success or failure for login requests, for logout dialogs, for post to wall dialogs and for get friends requests. You can take this sample application and add your own actions by just following the same pattern of adding menus and the corresponding calls to Facebook with the corresponding callbacks to receive state messages.
The implementer of DialogListener must implement the appropriate completion logic; for example, this is used during login and wall post requests. The core SDK Facebook. The method creates the appropriate WebView dialog. For example, to publish a status message, you make a call to the core Facebook class method dialog passing the action stream. The result of this call is the Facebook web-based publish to wall dialog as in Posting to the wall.
The user can skip or go ahead and publish the message. This use of native and web content together within the same mobile application is a great example of the power of hybrid applications.
The Facebook Platform provides support for OAuth 2. You should avoid using the older authentication scheme when writing new applications as support for this older scheme will not be available in the near future.
For more information about OAuth, see the OAuth 2. This is an interesting approach for a couple of reasons:. One disadvantage of this approach is that it might feel slower sometimes than a pure native implementation.
But to make this work, you must first sign your application, then generate a signature or key hash see Generating the application key hash. Note that the code in Generating the application key hash normally appears on a single line. It is split to multiple lines for formating purposes. You must then register the generated key hash on Facebook for your particular application under the mobile and devices section as in Enter the application key hash. View a larger version of Enter the application key hash.
The rest of the article focuses on this default approach. To access private data, the application must request and the user must grant to the application permissions to do so.
The permissions to gain access to private data are referred to as Extended Permissions. The method starts either an Activity native Facebook app, if present and configured or a the WebView dialog to prompt the user for credentials authentication and permissions authorization , see The authorize method.
Note that for the single sign-on authentication to properly work, you must include a call to the authorizeCallback method in your onActivityResult function. Recall from Handling the menu selection how the login menu item invokes the authorize method with permissions.
Call the authorize method with permissions shows how to invoke the authorize method with permissions to write content. The authorize method internally invokes the dialog method previously covered, but this time it passes a Login request for action. For detailed information on how authentication works, see the Facebook Authentication page in Related links. Calling the authorize method results in the WebView-based dialogs in The authorize and permissions screens WebView.
After the user logs in, she is prompted for permissions email or phone information and a password as requested by the application. As an example of an API request, you will make a request to retrieve the friends for the authenticated user. Recall the structure of a Graph API:. Dispatching a request asynchronously shows a snippet from Handling the menu selection on how to make the request method call. In this example, you use the AsyncFacebookRunner. This step is done to avoid blocking the main UI thread.
The FriendsRequestListener onComplete This method parses the returned JSON for the list of friends. Note that Processing the get friends request does not show all of the implemented methods. According to your application requirements, the response from the Facebook servers, which is in JSON format, must be parsed and processed accordingly. You might decide to display such information by using a WebView or by using a ListView as in this SampleApp see Displaying the results. In this article, you looked at Facebook APIs.
With this information, you now have a better understanding of the different Facebook APIs that are available and of how to start writing Facebook applications for the Android platform.

In many cases, it may be the screen of your app where users interact with the app the most. Users expect that the content will seamlessly keep pace with their fingers as they scroll on a touchscreen. To get your list to appear as if it scrolls smoothly, you need to render about 60 frames of it per second. Basic arithmetic translates this challenge into rendering one frame in under

ListView is an important UI component of Android applications; it is used everywhere from short lists of menu options to long lists of contacts or internet favorites. It provides a simple way to present a scrolling list of rows that can either be formatted with a built-in style or customized extensively. List views and adapters are included in the most fundamental building blocks of Android Applications.

Create Custom List View In Your Android Application
You can retrieve user friends list in several ways. Using new graph api you can retrieve friend-list or you can call legacy api to retrieve friend-list. Can I get friendlist of any user using this method? Or only friendlist of user that using my app? Thank you for reply. Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. How is possible?
My previous tutorial Android Custom ListView covers customizing android list view with image and text. I used android volley network library to make http calls and download the images. To demonstrate this tutorial I created an example json feed which contains an array of json feed object. Each object defines single feed row where it contains information like feed id , profile pic , profile name , timestamp , status message and feed image.
Adding friends on Facebook gives them access to your personal information, posts and photos, including the contents of your Facebook wall. The friends on your Restricted list will see only the content that you have chosen to share publicly, or the photos and posts in which you have tagged the individual friend. Type the name of the friend who you want to add to the list. Facebook auto-suggests names from your friends list as you type.
