Can't get name and email from facebook

I'm trying to get name and email from facebook login.
I'm using: compile 'com.facebook.android:facebook-android-sdk:4.+'
I can get into onSuccess but the code does not get into GraphRequest and I think that's why I can't get name and email (I'd also like get Profile picture)
I got the autogenerated code (GraphRequest) from facebook developer Explorer Api Graph
public class LoginActivity
{
LoginButton buttonLoginFacebook;
#Nullable
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
buttonLoginFacebook = (LoginButton) findViewById(R.id.connectWithFbButton);
buttonLoginFacebook.setReadPermissions(Arrays.asList(
"public_profile", "email"));
FacebookSdk.setIsDebugEnabled(true);
FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
FacebookSdk.addLoggingBehavior(LoggingBehavior.REQUESTS);
buttonLoginFacebook.setOnClickListener(this);
buttonLoginFacebook.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
//----->THE CODE JUMPS FROM HERE
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
mensajeFACEBOOK="TRYING TO GET NAME";
}
});
//----->TO HERE
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,first_name,last_name");
request.setParameters(parameters);
request.executeAsync();
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException error) {
}
});
}
}

This is how i do it. Hope this helps.

Actually GraphRequest.executeAsync() is an async method with a callback onCompleted so to read the data you need to do it inside the callback.
buttonLoginFacebook.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
//Read the data you need from the GraphResponse here like this:
try {
String firstName = response.getJSONObject().getString("first_name");
String lastName = response.getJSONObject().getString("last_name");
String email = response.getJSONObject().getString("email");
String id = response.getJSONObject().getString("id");
String picture = response.getJSONObject().getJSONObject("picture").getJSONObject("data").getString("url");
} catch (JSONException e) {
e.printStackTrace();
}
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,first_name,last_name,picture.width(150).height(150)");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException error) {
}
});
Also included the profile picture field picture.width(150).height(150) as you asked

Why can't I get a user's first name from a GraphRequest?

I want users to be able to register for my Android app using the Facebook SDK. To get their information, I am performing a GraphRequest with the permissions "email" and "public_profile." According to this page, the user's first and last name should be accessible in the "first_name" and "last_name" fields. However, when I click the button, I get an error saying that there is no value for first_name. The JSON array that is returned is along the lines of:
{"name":"First M. Last","id":"1234567890123456"}
I have not submitted my app for review, because it is not yet complete. Could this have something to do with this problem?

As per official documents your login for accessing public_profile permission should look like :
LoginManager.getInstance().logInWithReadPermissions(Login.this, Arrays.asList("public_profile", "email"));
To get Profile Info :
private void getFbDetails(final AccessToken accessToken) {
GraphRequest request = GraphRequest.newMeRequest(accessToken,
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Toast.makeText(Login.this, object.toString(), Toast.LENGTH_LONG).show();
Log.v("FB Details", object.toString());
if (object != null) {
name_fb = object.optString("name");
email_fb = object.optString("email");
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,first_name, last_name, email,link");
request.setParameters(parameters);
request.executeAsync();
}

You can get first name and last name as separate parameter. You can concat first name & last name to pass in api. I am using this method to get the user detail while using Facebook login.
// initalize the login button
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile");
loginButton.setReadPermissions("email");
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
raphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override

// Get facebook data from login
try {
Bundle bFacebookData = getFacebookData(object);
usernamestr = fbEmail;
} catch (JSONException e) {

}
}
});

Please help me.. Why I am not getting email id.

add permission of email in logInWithReadPermissions.
LoginManager.getInstance().logInWithReadPermissions(LoginActivity.this, Arrays.asList("public_profile", "email","user_friends"));

You probably need to add one more permission email. So, here you go,
LoginManager.getInstance().logInWithReadPermissions(LoginActivity.this, Arrays.asList("public_profile", "user_friends", "email"));

Facebook Android SDK 4.5.0 get email address

I'm currently creating a test application to test using the latest facebook SDK to update our existing application problem is that I need to get the email address which I know depends if the user has provided one on his account. Now the account I'm using to test provides one for sure but for unknown reason the facebook SDK only provides the user_id and the fullname of the account and nothing else. I'm confused on this since the the SDK3 and above provides more information than the updated SDK4 and I'm lost on how to get the email as all the answers I've seen so far doesn't provide the email on my end. Here's my code so far:
Login Button
#OnClick(R.id.btn_login)
public void loginFacebook(){
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "email"));
}
LoginManager Callback:
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
requestUserProfile(loginResult);
}
#Override
public void onCancel() {
Toast.makeText(getBaseContext(),"Login Cancelled", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(FacebookException e) {
Toast.makeText(getBaseContext(),"Problem connecting to Facebook", Toast.LENGTH_SHORT).show();
}
});
And the request for user profile:
public void requestUserProfile(LoginResult loginResult){
GraphRequest.newMeRequest(
loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject me, GraphResponse response) {
if (response.getError() != null) {
// handle error
} else {
try {
String email = response.getJSONObject().get("email").toString();
Log.e("Result", email);
} catch (JSONException e) {
e.printStackTrace();
}
String id = me.optString("id");
// send email and id to your web server
Log.e("Result1", response.getRawResponse());
Log.e("Result", me.toString());
}
}
}).executeAsync();
}
The JSON response returns only the ID and full name of my account but doesn't include the email. Did I missed out something?

You need to ask for parameters to facebook in order to get your data. Here I post my function where I get the facebook data. The key is in this line:
parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
btnLoginFb.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
System.out.println("onSuccess");
progressDialog = new ProgressDialog(LoginActivity.this);
progressDialog.setMessage("Procesando datos...");
progressDialog.show();
String accessToken = loginResult.getAccessToken().getToken();
Log.i("accessToken", accessToken);
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.i("LoginActivity", response.toString());
// Get facebook data from login
Bundle bFacebookData = getFacebookData(object);
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
System.out.println("onCancel");
}
#Override
public void onError(FacebookException exception) {
System.out.println("onError");
Log.v("LoginActivity", exception.getCause().toString());
}
});
private Bundle getFacebookData(JSONObject object) {
try {
Bundle bundle = new Bundle();
String id = object.getString("id");
try {
URL profile_pic = new URL("https://graph.facebook.com/" + id + "/picture?width=200&height=150");
Log.i("profile_pic", profile_pic + "");
bundle.putString("profile_pic", profile_pic.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
}
bundle.putString("idFacebook", id);
if (object.has("first_name"))
bundle.putString("first_name", object.getString("first_name"));
if (object.has("last_name"))
bundle.putString("last_name", object.getString("last_name"));
if (object.has("email"))
bundle.putString("email", object.getString("email"));
if (object.has("gender"))
bundle.putString("gender", object.getString("gender"));
if (object.has("birthday"))
bundle.putString("birthday", object.getString("birthday"));
if (object.has("location"))
bundle.putString("location", object.getJSONObject("location").getString("name"));
return bundle;
}
catch(JSONException e) {
Log.d(TAG,"Error parsing JSON");
}
return null;
}

Instead of getting the value of the graphResponse, access the email using the JSONObject me
userEmail = jsonObject.getString("email");

Hope it helps you
/*** setupFacebook stuff like make login with facebook and get the userId,Name and Email*/
private void setupFacebookStuff() {
Log.e(TAG, "key hash= " + Utils.getKeyHash(SplashActivity.this, getPackageName()));
// This should normally be on your application class

preference.setUserName(userEmail);
Log.e("useremail", userEmail);
}
callMainActivity(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
final Bundle parameters = new Bundle();
parameters.putString("fields", "name,email,id");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
Toast.makeText(getBaseContext(), "Login Cancelled", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(FacebookException error) {
Toast.makeText(getBaseContext(), "Problem connecting to Facebook", Toast.LENGTH_SHORT).show();
Log.e(TAG, "Facebook login error " + error);
}
});
}

You can also use GraphResponse object to get the values
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>()
{
#Override
public void onSuccess(LoginResult loginResult)
{
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.v("LoginActivity", response.toString());
try {
// Application code
String email = response.getJSONObject().getString("email");
txtStatus.setText("Login Success \n" + email);
}catch(Exception e){
e.printStackTrace();;
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel()
{
txtStatus.setText("==============Login Cancelled=============");
}
#Override
public void onError(FacebookException exception)
{
txtStatus.setText("==============Login Error=================");
exception.printStackTrace();
}
});

Putting this code:
btnLoginFb.setReadPermissions(Arrays.asList("email"));
before
RegisterCallback
should solve the problem.

I guess getting email permissions can help..
LoginManager.getInstance().logInWithReadPermissions(
fragmentOrActivity,
Arrays.asList("email"));

Information
If you are giving any permission to get an email address.
then, Facebook can not every time gives you email address or some other details.
When, Facebook user is not signup with his email-address then Facebook can't provide you his email address.
If user is login with Facebook using email address then Facebook will provides email to you.
Facebook SDK provide only public details.
check a login with Facebook using email-address and also with phone number through.
