发布消息到Facebook墙从android fb sdk总是错误 [英] Post message to facebook wall from android fb sdk always error

问题描述

我有安装fb sdk的问题（从 http://github.com/下载） Facebook的/ Facebook的Android的SDK ）。试图张贴墙，但总是得到错误（权限已经设置并登录到fb）

I have problem with fb sdk for Android (downloaded from http://github.com/facebook/facebook-android-sdk). Tried to post wall but always get error (permission already set and logged in to fb)

这里是代码片段onClick函数，我对他们的示例代码进行了小的修改：

here is the code snippet onClick function, i made small modifications on their sample code:

Bundle params = new Bundle();

params.putString("message", "Test");
params.putString("name", "American Virgin");
params.putString("link", "http://bit.ly/12345");
params.putString("description", "A Freshman College Girl on a scholarship from an ...");
params.putString("picture", "http://xxx/MOV1026.jpg");

mAsyncRunner.request("me/feed", params, "POST", new TestRequestListener());

从DDMS我得到以下错误：

From DDMS i get the following error:

推荐答案

真的很奇怪吗？我有一个应用程序使用相同的语法，但它的工作原理很好。我只是检查FB SDK的源代码，它似乎已经改变了很多... 我在SDK src 上找到了这个：

That's really weird... I have an app which uses the same syntax but it works really well. I just check the source code of the FB SDK and it seems it has changed a lot... I found this on the SDK src:

    for (String key : params.keySet()) {
        if (params.getByteArray(key) != null) {
                dataparams.putByteArray(key, params.getByteArray(key));
        }
    }

所以，你尝试这样做：

Bundle params = new Bundle();

params.putByteArray("message", "Test".getBytes());
params.putByteArray("name", "American Virgin".getBytes());
params.putByteArray("link", "http://bit.ly/12345".getBytes());
params.putByteArray("description", "A Freshman College Girl on a scholarship from an ...".getBytes());
params.putByteArray("picture", "http://xxx/MOV1026.jpg".getBytes());

mAsyncRunner.request("me/feed", params, "POST", new TestRequestListener());
