Java – Android Facebook login callback does not work properly
•
Android
I tried to use Facebook login to access user profile. But I'm confused about Facebook tutorial. So far, I think I've successfully logged in, but I can't get my profile. Here's my code
My fragment class:
public class FBLoginFragment extends Fragment {
private LoginButton loginButton;
private CallbackManager callbackManager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_fblogin, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
loginButton = (LoginButton) view.findViewById(R.id.login_button);
loginButton.setFragment(this);
loginButton.setReadPermissions("user_friends");
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
// App code
if(profile != null) System.out.println("login successful " + profile.getName());
}
@Override
public void onCancel() {
// App code
System.out.println("login cancel");
}
@Override
public void one rror(FacebookException exception) {
// App code
System.out.println("login fail");
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
}
My main activity Code:
public class LoginActivity extends ActionBarActivity {
private Fragment fragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
}
}
resolvent:
In your manifest file, an activity that contains a Facebook login button may have a nohistory attribute as follows:
<activity
...
android:noHistory="true"
... >
Deleting it will fix your problem
