我正在尝试创建一个Facebook实用程序类,到目前为止它工作得很好,但是当我在比ICS更大的API上测试时,我得到了这个错误。

如果我的类看起来像这样,我该如何实现AsyncFacebookRunner

{

public String msg;
public Context ctx;
public Facebook fb;
public SharedPreferences sp;

public ShareFacebook(String msg, Context ctx, Facebook fb, SharedPreferences sp)
{
    this.msg = msg;
    this.ctx = ctx;
    this.fb = fb;
    this.sp = sp;

}

public void send()
{
    if (fb.isSessionValid())
    {
        postWall();
    }
    else
    {

        fb.authorize((Activity) ctx, new String[] {"email", "publish_checkins",
            "publish_stream"}, new DialogListener()
        {

            @Override
            public void onFacebookError(FacebookError e)
            {
                e.printStackTrace();   

            } 

            @Override
            public void onError(DialogError e) 
            {
                Toast.makeText(ctx,R.string.facebookError, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onComplete(Bundle values)
            {
                Editor editor = sp.edit();
                editor.putString("access_token", fb.getAccessToken());
                editor.putLong("access_expires", fb.getAccessExpires());
                editor.commit();
                postWall();
            }

            @Override
            public void onCancel()
            {

            }
        });
    }

}

private void postWall()
{
    Bundle params = new Bundle();
    params.putString("message",  msg );
    params.putString("link",ctx.getResources().getString(R.string.rateLink));
    params.putString("picture",
        ctx.getResources().getDrawable(R.drawable.ic_launcher).toString());
    try
    {
        fb.request("me/feed", params, "POST");
        Toast.makeText(ctx,R.string.facebookSuccess, Toast.LENGTH_SHORT).show();
    }
    catch (FileNotFoundException e)
    {
        e.printStackTrace();
    }
    catch (MalformedURLException e)
    {
        e.printStackTrace();
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }

}

}

谢谢:)

答案 0 :(得分:0)

您无法从UI线程调用Facebook.request()。

它只发生在ICS及以上版本,因为ICS会检查以确保您不会尝试在UI线程上进行网络通信。

来自facebook api的方法评论:

  

请注意,此方法会阻止等待网络响应,因此请勿在UI线程中调用它。

创建一个线程并从线程运行fb.request应该可以解决错误。
