My issue is very simple, I want users to login using Facebook. After a successful login, grab some details and pass it on another activity. I have my new class in manifeset. I see the log for Log.v("facebook - profile", profile.getFirstName()); I'm quite baffled about what's going on. I have no errors either. I'm passing my activity in the onSuccess.
public class MainActivityFragment extends Fragment {
TextView textview;
private AccessTokenTracker tokenTracker;
private ProfileTracker profileTracker;
private CallbackManager mCallbackManager;
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
if(Profile.getCurrentProfile() == null) {
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
Log.v("facebook - profile", profile2.getFirstName());
profileTracker.stopTracking();
}
};
profileTracker.startTracking();
}
else {
Profile profile = Profile.getCurrentProfile();
Log.v("facebook - profile", profile.getFirstName());
//get info to pass to next activity
String[] profileDetailsArray = new String [5];
profileDetailsArray[0] = profile.getFirstName();
profileDetailsArray[1] = profile.getLastName();
profileDetailsArray[2] = profile.getId();
Bundle arrayBundle = new Bundle();
arrayBundle.putStringArray("profileDetails",profileDetailsArray);
Intent intent = new Intent(getActivity(),LandingPage.class);
intent.putExtras(arrayBundle);
startActivity(intent);
}

I wan't to force logout from facebook when I exit the application so I have to login every time I start the application. If that is not possible I need help with checking if a user is already logged in.
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(final LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
try {
if (object != null) {
name = object.getString("first_name") + " "+object.getString("last_name");
email = object.getString("email");
mTextDetails.setText("Welcome " + name);
editor.putString("username", name);
editor.putString("email", email);
editor.apply();
}
} catch (JSONException e) {
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email, first_name, last_name, gender");
request.setParameters(parameters);
request.executeAsync();
}
// }

return view;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {

You can use this LoginManager.getInstance().logOut();
Sorry my english ! need call another activity automatic, more not know where to put code, "facebook login sdk" It how is code, "startActivity" not function

If you are trying to start an activity as soon as the user successfully logs in, you can call startActivity(intent) in the onSuccess(LoginResult loginResult) method of the FacebookCallback.
try this in onSuccess method
GraphRequest request = GraphRequest.newMeRequest(
accessToken,
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
try {
String name = object.getString("name");
String id = object.getString("id");
Intent redirect=new Intent(Login_Activity.this,anotheractivity.class);
startActivity(redirect);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
I have the following class that I instantiate from my fragment:
public class FacebookLogin {
private CallbackManager mCallbackManager;
private LoginButton lButton;
private AccessToken accessToken;
private Profile profile;
private static final String TAG = "FacbookLogin";
public FacebookLogin(Context c) {
FacebookSdk.sdkInitialize(c);
mCallbackManager = CallbackManager.Factory.create();
Log.i(TAG, " Constructor called");
}
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i(TAG, " logged in...");
AccessToken accessToken = loginResult.getAccessToken();
profile = Profile.getCurrentProfile(); //Access the profile who Is the person login i
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
Log.i(TAG, " Error");
Log.e(TAG, e.getMessage());
}
};
public void setCallback(LoginButton lButton) {
lButton = lButton;
lButton.registerCallback(mCallbackManager, mCallback);
Log.i(TAG, " setCallback called");
}
And here Is my fragment-class:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fLogin = new FacebookLogin(getActivity().getApplicationContext());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.login, container, false);
return v;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
final LoginButton loginButton = (LoginButton) getView().findViewById(R.id.login_button);
final TextView infoText = (TextView) getView().findViewById(R.id.text_details);
loginButton.setFragment(this);
loginButton.setReadPermissions("user_friends");
loginButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.i(TAG, " Button clickde");
fLogin.setCallback(loginButton); //Let's register a callback
profile = fLogin.getProfile();
if (profile != null) {
Log.i(TAG, profile.getName()); //Call this after the callback request Is finished
} else {
Log.i(TAG, "NULL....... inside onresume");
}
}
});
}
I want to call profile = fLogin.getProfile(); after the callback request is complete. But I don't know how to do this. I have read about the onComplete();, but I don't know how to Implement It here.
How and Where do I set view contents to be displayed for persons who has successfully been authenticated using Facebook SDK?
After the persons has logged In, I want to display a User profile view.
I have tried to Instansiate a new fragment like the code below, but that don't work. The text "Fish" Is not displayed.
public class LoginFragment extends Fragment {
private CallbackManager mCallbackManager;
private static final String TAG = "Facebook";
private LoginButton login;
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i(TAG, " logged in...");
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile(); //Access the profile who Is the person login in
if(profile != null) {
FragmentManager fm = getFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmentContainer);
if(fragment == null) {
fragment = new LoggedInFragment();
fm.beginTransaction().add(R.id.fragmentContainer, fragment).commit();
}
}
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
Log.i(TAG, " Error");
}
};
public LoginFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
mCallbackManager = CallbackManager.Factory.create();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.login, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
//Ask the use for permission to access friends
loginButton.setReadPermissions("user_friends");
//Because we work with fragments
loginButton.setFragment(this);
loginButton.registerCallback(mCallbackManager, mCallback);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
}
Here IS fragement that the user should see when he/she Is logged In:
package com.waddapp.bryan.waddapp;
public class LoggedInFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.logged_in, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
TextView mTextDetails = (TextView)view.findViewById(R.id.text_details);
mTextDetails.setText("FISH");
}
public LoggedInFragment() {
}
}
Anyone who can explain how acomplish this?
I have nested fragment like the following.
MainActivity
FragmentA
FragmentA1
FragmentA3
FragmentA2
FragmentB
FragmentB1
I want to login facebook from FragmentA3. But can not.
In FragmentA3, my app stop in onResume after called onActivityResult.
What should I do?
FragmentA3
public class FragmentA3 extends Fragment {
public static final String TAG = FragmentA3.class.getCanonicalName();
private UiLifecycleHelper mFbSdkUiHelper;
private OnLoggedListener mCallback;

}
public interface OnLoggedListener {
//Callback to notify about login success.
public void onLoginSuccess();
}
private final Session.StatusCallback mSessionCallback = new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state, Exception exception) {
onSessionStateChange(session, state, exception);
}
};
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
Log.d(TAG,"onSessionStateChange");
if (state.isOpened()) {
mCallback.onLoginSuccess();
} else if (state.isClosed()) {
if (session != null) {
session.closeAndClearTokenInformation();
}
}
}
#Override
public void onCreate(Bundle savedInstanceState) {
Log.d(TAG,"onCreate");
super.onCreate(savedInstanceState);
mFbSdkUiHelper = new UiLifecycleHelper(getActivity(), mSessionCallback);
mFbSdkUiHelper.onCreate(savedInstanceState);
}
#Override

View rootView = inflater.inflate(R.layout.others_fblogin, container, false);
LoginButton loginButton = (LoginButton) rootView.findViewById(R.id.login_button);
loginButton.setFragment(this);
loginButton.setReadPermissions(permissions);
return rootView;
}
#Override
public void onAttach(Activity activity) {
Log.d(TAG,"onAttach");
super.onAttach(activity);
try {
mCallback = (OnLoggedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnLoggedListener in order to use this fragment");
}
}
#Override
public void onResume() {
Log.d(TAG,"onResume");
super.onResume();
Session session = Session.getActiveSession();
if (session != null && (session.isOpened() || session.isClosed())) {

}
mFbSdkUiHelper.onResume();
}

Please try this solution:
public class FragmentA3 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Fragment fragmentA1 = this.getParentFragment();
Fragment fragmentA = fragmentA1.getParentFragment();
loginButton.setFragment(fragmentA);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG,"onActivityResult");
super.onActivityResult(requestCode, resultCode, data);
mFbSdkUiHelper.onActivityResult(requestCode, resultCode, data);
}
}
public class FragmentA1 extends Fragment {
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (mFragmentA3 !=null)
mFragmentA3.onActivityResult(requestCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);
}
}
public class FragmentA extends Fragment {
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (mFragmentA1 !=null)
mFragmentA1.onActivityResult(requestCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);
}
}
Step 1: Add the below code in the fragment.
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState){
context = getContext();
FacebookSdk.sdkInitialize(context);
View view = inflater.inflate(R.layout.fragment_facebook_sign_in, container, false);
}
Step 2: Handle the callback of facebook.
private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
try {
String email = object.getString("email");
String firstName = object.getString("first_name");
String lastName = object.getString("last_name");
profile_link = object.getString("link");
String profilePicUrl = object.getJSONObject("picture").getJSONObject("data").getString("url");
Utility.logMe("\nFacebook_user_mail:"+email +"\nFacebook_user_Fname:"+firstName+"\nFacebook_user_Lname:"+lastName+"\nFacebook_user_Image:"+profilePicUrl+"\nProfile_link:"+profile_link);
if(email != null && email.length()> 0)
{
LoginManager.getInstance().logOut();
signUpFacebook(firstName, lastName, email, profilePicUrl, profile_link);
}
else {
Toast.makeText(getActivity(), "Email not present to login", Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
Toast.makeText(getActivity(), "Email Not Exist for this user on Facebook.", Toast.LENGTH_LONG).show();
progressDialog = new ProgressDialog(getContext());
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,link,name,email,birthday,gender,first_name,last_name,picture.type(large)");
request.setParameters(parameters);
request.executeAsync();
}
Step 3:
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
callbackManager = CallbackManager.Factory.create();
accessTokenTracker= new AccessTokenTracker() {
#Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
//displayMessage(newProfile);
}
};
accessTokenTracker.startTracking();
profileTracker.startTracking();
}
Step 4:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
textView = (TextView) view.findViewById(R.id.textView);
loginButton.setReadPermissions("user_friends");
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, callback);
}
Step 5:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
Step 6:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
List<Fragment> allFragments = getSupportFragmentManager().getFragments();
for (Fragment fragmento : allFragments) {
if (fragmento instanceof TwitterSignIn) {
((TwitterSignIn) fragmento).onActivityResult(requestCode, resultCode, data);
}
if (fragmento instanceof GooglePlusSignIn) {
((GooglePlusSignIn) fragmento).onActivityResult(requestCode, resultCode, data);
}
if (fragmento instanceof FacebookSignIn) {
((FacebookSignIn) fragmento).onActivityResult(requestCode, resultCode, data);
}
}
}
