我在 android 中为 facebook android 集成制作了一个简单的程序，我尝试如下：它显示 facebook 登录对话框并成功登录，之后它还显示 myapp 并要求与我的 facebook 朋友分享，但是当我按下“是” “..它说无法在墙上发布”....请告诉我问题出在哪里，我的代码如下：
main.java
package com.example.facbk;

editor.putString(TOKEN, facebook.getAccessToken());
editor.putLong(EXPIRES, facebook.getAccessExpires());
System.out.println("hello token");
System.out.println(facebook.getAccessToken());
return editor.commit();
}
public boolean restoreCredentials(Facebook facebook) {
SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
return facebook.isSessionValid();
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebook = new Facebook(APP_ID);
restoreCredentials(facebook);

try {

String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
showToast("Blank response.");
}
else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
class LoginDialogListener implements DialogListener {

}
}
