Question

我使用下面显示的代码发布到Facebook，问题是，当我发送几条消息时，让我们说消息A，B，C，......当我发送BI时，请在网上看到A，我需要发送C来看B，我的意思是，总有一条消息延迟，为什么会这样？

import android.app.Activity;
import android.content.Context;

    public FbManager(Context context, CallbackManager callbackManager){
        this.context = context;

        }
        catch (Exception e) {

    }

        if (isLoggedIn()) {

                }

                @Override
                public void onError(FacebookException exception) {
                    Log.e(LOGTAG, "facebook login error");
                    exception.printStackTrace();

我已经解决了改变的问题

    Bundle postParams = new Bundle();
    postParams.putString("message", msg);
    postParams.putString("picture", "http://lh5.ggpht.com/-YP1POFWKolqatDOsX5yKYwvR6k1kj5dL4yxeKkBiL8sp6JE3l8Ty9tJt-zqzI2jj1Uu=w300");
    postParams.putString("link", "http://goo.gl/FYssFq");

由此：

    Bundle postParams = new Bundle();
    postParams.putString("message", msg + " http://goo.gl/FYssFq");
    postParams.putString("picture", "http://lh5.ggpht.com/-YP1POFWKolqatDOsX5yKYwvR6k1kj5dL4yxeKkBiL8sp6JE3l8Ty9tJt-zqzI2jj1Uu=w300");
    //postParams.putString("link", "http://goo.gl/FYssFq");

对于某些参数组合以及指向Google Play的链接，它必定是Facebook的错误

错误可以从不同设备交替传递消息，因此它必须位于服务器facebook端

Android：发帖到facebook推迟了一个帖子，我看不到最后的帖子请求 - FB SDK 4.x.
