我按照这个方法在没有对话框的情况下发布 Facebook 状态更新，来自 SO 上的这个答案:https://stackoverflow.com/a/7528388/450534
我可以发布应用 Activity 的状态更新，但它仍在生成警告。
这是来自 DDMS 的一长串警告。任何有关解决问题的建议都将受到赞赏。
代码:
protected void postToWall(String message) {
if (!Utility.mFacebook.isSessionValid()) {
Util.showAlert(this, "Warning", "You must first log in.");
}
Log.d("Tests", "Testing graph API wall post");
try {
String response = Utility.mFacebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("message", txtPostToWall.getText().toString());
// parameters.putString("description", getString(R.string.app_desc));
response = Utility.mFacebook.request("me/feed", parameters, "POST");
txtPostToWall.setText("");
this.finish();
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") || response.equals("false")) {
Log.v("Error", "Blank response");
}
}
catch(Exception e) {
e.printStackTrace();
}
}
DDMS 警告:(非常非常冗长。)

很好很好很好。我觉得自己完全是个白痴，因为我忽略了重要的警告……:-(
诀窍是在第 69 行更改 Facebook SDK 中的 Util.java:
if (parameters.getByteArray(key) != null) {
到:
if (parameters.get(key) instanceof byte[]) {
