使用Facebook登录并通过相机捕获照片并在自己的墙上共享

Question

我搜索了许多站点，但仍然无法解决此问题，问题是我似乎无法发布数据。

我的代码：

public class MainActivity extends Activity {

    // Your Facebook APP ID
    private static String APP_ID = "397909153726269"; // Replace with your App ID

    // Instance of Facebook Class
    private Facebook facebook = new Facebook(APP_ID);
    private AsyncFacebookRunner mAsyncRunner;
    String FILENAME = "AndroidSSO_data";
    private SharedPreferences mPrefs;

    // Buttons
    Button btnFbLogin;
    Button btnFbGetProfile;
    Button btnPostToWall;
    Button btnShowAccessTokens;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnFbLogin = (Button) findViewById(R.id.btn_fblogin);
        btnFbGetProfile = (Button) findViewById(R.id.btn_get_profile);

        btnShowAccessTokens = (Button) findViewById(R.id.btn_show_access_tokens);
        mAsyncRunner = new AsyncFacebookRunner(facebook);

        /**

        btnFbLogin.setOnClickListener(new View.OnClickListener() {

我尝试了一个来自androidhive的示例，但它似乎不起作用，任何帮助都将非常androidhive 。

提前致谢。

Answer 1

首先，您使用的是SDK的超旧版本（来自v2的Facebook类已弃用了将近3年）。 最新的是v4.x。

另一个问题是您正在使用Graph API v1中的权限，并且自2015年4月30日起已完全弃用。 一个示例是publish_stream权限已被publish_actions取代。

您应该在此处查看“共享”文档： https : //developers.facebook.com/docs/sharing ，还可以在此处下载SDK的最新版本： https : //developers.facebook.com/docs/android
