我是新来的FB SDK for android。我按照原样遵循示例教程。但我发现了这个错误：面向Android的Facebook：会话尝试请求会话的新权限
这是MainFragment.class代码：
private static final String TAG = "MainFragment";
private UiLifecycleHelper uiHelper;
private TextView userInfoTextView;
private Button shareButton;
private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");
private static final String PENDING_PUBLISH_KEY = "pendingPublishReauthorization";
private boolean pendingPublishReauthorization = false;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
LoginButton authButton = (LoginButton) view.findViewById(R.id.authButton);
authButton.setFragment(this);
if (savedInstanceState != null) {
pendingPublishReauthorization =
savedInstanceState.getBoolean(PENDING_PUBLISH_KEY, false);
}
authButton.setReadPermissions(Arrays.asList("user_location", "user_birthday", "email"));
// This opens a webview to type your email/username and password
//authButton.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
userInfoTextView = (TextView) view.findViewById(R.id.userInfoTextView);
shareButton = (Button) view.findViewById(R.id.shareButton);
shareButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
publishStory();
}
});
return view;
}
private String buildUserInfoDisplay(GraphUser user) {
StringBuilder userInfo = new StringBuilder("");
// Example: typed access (name)
// - no special permissions required
userInfo.append(String.format("Name: %s\n\n",
user.getName()));
// Example: typed access (birthday)
// - requires user_birthday permission
userInfo.append(String.format("Firstname: %s\n\n",
user.getInnerJSONObject()));
userInfo.append(String.format("Username: %s\n\n",
user.getUsername()));
userInfo.append(String.format("ID: %s\n\n",
user.getId()));
userInfo.append(String.format("Email: %s\n\n",
user.asMap().get("email")));
userInfo.append(String.format("Gender: %s\n\n",

return userInfo.toString();

我只是检查了所有的问题在这里StackOverflow上与我相似，但我没有找到一个解决我问题。有任何想法吗？我很乐意感谢你的帮助。谢谢。
