Question

我已经构建了一个使用this实现的活动（请参阅接受的答案），在用户的Facebook墙上发布状态更新。

如果模拟器/手机没有安装Facebook应用程序，则没有问题。

如果模拟器/手机安装了Facebook应用程序，Facebook应用程序会加载登录屏幕，但在尝试登录后，Facebook应用程序就会消失，让我回到我的应用程序。

有没有人在安装Facebook应用程序时有过这种体验？

我的代码：

public class AchievementActivity extends Activity implements DialogListener, OnClickListener{


private Facebook facebook;
Button facebookPostButton;
String defaultFacebookPost;

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
    setContentView(R.layout.achievements);
    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title_layout);

    View achievementDivider = (View)findViewById(R.id.achievementDivider);
    int[] colors = {0, 0xff00ffff, 0};
    achievementDivider.setBackgroundDrawable(new GradientDrawable(Orientation.RIGHT_LEFT, colors));

    //get the title of the achievement from the intent that started this activity from the activity StatisticsActivity
    String achievementTitleString = getIntent().getStringExtra("title");

    String achievementTextToDisplay = getAchievementTextToDisplay(achievementTitleString);

    defaultFacebookPost = getDefaultPost(achievementTitleString);

    //ImageView achievementActivityAchievementBadgeImageView = (ImageView)findViewById(R.id.achievementActivityAchievementBadgeImageView);
    TextView achievementActivityBadgeTitleTextView = (TextView)findViewById(R.id.achievementActivityBadgeTitleTextView);
        achievementActivityBadgeTitleTextView.setText(achievementTitleString);

    TextView achievementActivityAchievementText = (TextView)findViewById(R.id.achievementActivityAchievementText);
        achievementActivityAchievementText.setText(achievementTextToDisplay);

    facebookPostButton = (Button)findViewById(R.id.facebookPostButton);
    facebookPostButton.setOnClickListener(this);


}

@Override
public void onComplete(Bundle values) {

    if (values.isEmpty())
    {
        Toast.makeText(getApplicationContext(), "Empty", Toast.LENGTH_SHORT);

        return;
    }

    if (!values.containsKey("post_id"))
    {
        try
        {
            Bundle parameters = new Bundle();
            parameters.putString("message", defaultFacebookPost);// the message to post to the wall
            facebook.dialog(AchievementActivity.this, "stream.publish", parameters, this);// "stream.publish" is an API call
        }
        catch (Exception e)
        {
            // TODO: handle exception
                System.out.println(e.getMessage());
        }
    }

    try 
    {
        facebook.logout(getApplicationContext());
    } 
    catch (MalformedURLException e) 
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 
    catch (IOException e) 
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

@Override
public void onFacebookError(FacebookError error) 
{
    Toast.makeText(AchievementActivity.this, "onFacebookError", Toast.LENGTH_LONG); 
}

@Override
public void onError(DialogError e) 
{
    Toast.makeText(AchievementActivity.this, "onError", Toast.LENGTH_LONG); 
}

@Override
public void onCancel() 
{
    Toast.makeText(AchievementActivity.this, "onCancel", Toast.LENGTH_LONG);
}

@Override
public void onClick(View v)
{
    if (v == facebookPostButton)
    {
        facebook = new Facebook("my_facebook_api");
        // replace APP_API_ID with your own
        facebook.authorize(this, new String[] {"publish_stream", "read_stream", "offline_access"}, this); 
    }
}

private String getDefaultPost(String defaultTitleString) 
{
    //do some stuff here to get a string to post to wall

    return defaultPost;
}

private String getAchievementTextToDisplay(String achievementTitleString) {
    String achievementTextToDisplay = "DEFAULT";

    //do some stuff here to get text to display in the activity
            //this has nothing to do with the facebook post...

    return achievementTextToDisplay;
}

}

修改：在过去一年中必须在多台机器上安装Android开发平台并且在创建新的开发环境后总是遇到Facebook的问题，我发现这个简单的答案可能是Facebook实现在一个设备上工作的原因不是另一个......

您使用不同证书打包的每个应用版本的秘密Facebook API密钥（您在developer.facebook.com上列出的密钥）都会有所不同。例如，假设您有两台开发机器。由于这两台计算机都将使用不同的证书构建您的应用程序，因此您必须确保为每台计算机生成一个Facebook API密钥，并将它们列在developer.facebook.com上。

Answer 1

我找到了一种解决方法，但到目前为止并不是最好的。

facebook.authorize(activity, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, 
                new LoginDialogListener());

如果设备上安装了官方Facebook应用，则会强制您的应用不使用SSO。但必须有一个更好的解决方案，因为有些应用程序使用sso与官方的Facebook应用程序。

Answer 2

这是因为当您登录Facebook帐户时，您的登录会话将在设备中创建。完成任务后，您必须从Facebook注销。

Answer 3

private static final String[] PERMISSIONS =
        new String[] {"publish_stream", "read_stream", "offline_access"};  




@Override
public void onClick(View v)
{
    if (v == facebookPostButton)
    {
        mAsyncRunner    = new AsyncFacebookRunner(mFacebook);
                                   mAsyncRunner.request(mFacebook.logout(getApplicationContext()), new LogoutListener());
                        mFacebook.authorize(FacebookImplement.this, PERMISSIONS, new AuthorizeListener());
    }
}



public class AuthorizeListener extends BaseDialogListener {

        public void onComplete(Bundle values) {

           Bundle params = new Bundle();
           params.putString("message"," Message");
       params.putString("description", "Wall Posting Description");        
        mAsyncRunner.request("me/feed", params, "POST",
                new UploadListener());         

        }

}

public class UploadListener extends BaseRequestListener {

        public void onComplete(final String response) {
              mAsyncRunner.request(mFacebook.logout(getApplicationContext()), new LogoutListener());
}

}

 public class LogoutListener extends BaseRequestListener {


        public void onComplete(final String response) {         



        }
    }

可能是这段代码可以帮到你。如果有任何问题，请立即询问。
