当我为 Facebook 的 Android SDK 使用单点登录时,我得到了一个完全无用的页面。
"You have already authorized app. Press "Okay" to continue.
这个页面会破坏用户体验。我怎样才能删除这个屏幕?
提前致谢。
注意:如果设备中安装了 FB 应用程序,我们不会看到此问题。仅当 FB 应用程序在设备中不可用时才会引发。

我正在使用Facebook SDK 3.6
我认为的最新版本,并且到目前为止已经在HTC One和Galaxy s3 mini上进行了测试。此页面在任何时候都不会为我显示。我在这里遵循了 API 指南...

这也是代码......也许这可能会有所帮助。
public class LoginHandlerFrag extends Fragment {
private UiLifecycleHelper uiHelper;
private static final String TAG = "HomeFragment";
// private ProfilePictureView profilePictureView;
private Session.StatusCallback callback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
onSessionStateChange(session, state, exception);
}
};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_login, container,
false);
LoginButton authButton = (LoginButton) view
.findViewById(R.id.authButton);
authButton.setReadPermissions(Arrays.asList("email", "user_location",
"user_birthday", "user_likes", "user_photos"));
authButton.setFragment(this);
Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
return view;
}
private void makeMeRequest(final Session session) {
// Make an API call to get user data and define a
// new callback to handle the response.
Request request = Request.newMeRequest(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user, Response response) {
// If the response is successful
if (session == Session.getActiveSession()) {
if (user != null) {
// profilePictureView.setProfileId(user.getId());
}
}
if (response.getError() != null) {
// Handle errors, will do so later.
}
}
});
request.executeAsync();
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(getActivity(), callback);
uiHelper.onCreate(savedInstanceState);
}
private void onSessionStateChange(Session session, SessionState state,
Exception exception) {
session = Session.getActiveSession();
SharedPreferences storedPrefs = PreferenceManager
.getDefaultSharedPreferences(getActivity().getApplicationContext());
SharedPreferences.Editor editor = storedPrefs.edit();
editor.putBoolean("userLoggedTracker", true);
editor.commit();
if (state.isOpened()) {
Log.i(TAG, "Logged in...");
makeMeRequest(session);
editor.putBoolean("userLoggedTracker", false);
editor.commit();
getView().setVisibility(View.GONE);
} else if (state.isClosed()) {
Log.i(TAG, "Logged out...");
editor.putBoolean("userLoggedTracker", true);
editor.commit();
getView().setVisibility(View.VISIBLE);
}
}
@Override
public void onResume() {
super.onResume();
Session session = Session.getActiveSession();
if (session != null && (session.isOpened() || session.isClosed())) {
onSessionStateChange(session, session.getState(), null);
}
uiHelper.onResume();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data);
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
uiHelper.onSaveInstanceState(outState);
}
}
在我将此代码用于 Facebook 注销之前:
if (AccessToken.getCurrentAccessToken() == null) {
return; // already logged out
}
new GraphRequest(AccessToken.getCurrentAccessToken(), "/me/permissions/", null, HttpMethod.DELETE, new GraphRequest
.Callback() {
@Override
public void onCompleted(GraphResponse graphResponse) {
LoginManager.getInstance().logOut();
}
}).executeAsync();
更改为此代码后LoginManager.getInstance().logOut();
解决了该问题。
