我的 Android 版 fb sdk 有问题（从下载http://github.com/facebook/facebook-android-sdk http://github.com/facebook/facebook-android-sdk）。尝试发布墙但总是出错（权限已设置并登录到 fb）
这是 onClick 函数的代码片段，我对其示例代码做了一些小修改：
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：

修复方法是：
if (parameters.get(key) instanceof byte[]) {
代替
if (parameters.getByteArray(key) != null) {
在 Util.java 第 63 行。
And
if (params.get(key) instanceof byte[]) {
代替
if (params.getByteArray(key) != null) {
在 Util.java 的第 155 行。
由于某些奇怪的原因，在 Samsung Nexus S（也许其他设备也是如此）上它返回一个 String，而不是 byte[]。
