从android fb sdk向facebook墙发布消息总是错误 [英] Post message to facebook wall from android fb sdk always error

问题描述

我有 Android 版 fb sdk 的问题(从 http://github.com/下载)facebook/facebook-android-sdk).尝试贴墙但总是出错(已设置权限并登录到 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)

这是 onClick 函数的代码片段，我对他们的示例代码做了一些小的修改:

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 我收到以下错误:

From DDMS i get the following error:

推荐答案

这真的很奇怪...我有一个应用程序，它使用相同的语法，但效果很好.我只是检查了 FB SDK 的源代码，它似乎发生了很大变化...... 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());
