Heres the method im using and it returns the id and name no problems.
// Private method to handle Facebook login and callback
private void onFblogin() {
callbackmanager = CallbackManager.Factory.create();
// Set permissions
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("email", "public_profile"));
LoginManager.getInstance().registerCallback(callbackmanager,
new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
System.out.println("Success");
GraphRequest.newMeRequest(
loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject json, GraphResponse response) {
if (response.getError() != null) {
// handle error
System.out.println("ERROR");
} else {
System.out.println("Success");
try {
String jsonresult = String.valueOf(json);
System.out.println("JSON Result" + jsonresult);
// String str_email = json.getString("email");
String str_email = json.getString("email");
String str_name = json.getString("name");
String str_id = json.getString("id");
//
// Save your info
settings = getSharedPreferences("login_details", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("name", str_name);
editor.putString("email", str_email);
editor.commit();
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}).executeAsync();
Intent openNewActivity = new Intent(getApplicationContext(), MainActivity.class);
startActivity(openNewActivity);
}
#Override
public void onCancel() {
Log.d("TAG_CANCEL", "On cancel");
}
#Override
public void onError(FacebookException error) {
Log.d("TAG_ERROR", error.toString());
}
});
}
The problem i have is that email doesnt return.
Ive tested the permissions with another app that can get my email when i sign in so permissions seem fine. Im assuming im calling it wrong now.
Try this just before executing your AsyncTask.
You can do this inside your onSuccess() method of the FacebookCallback().
GraphRequest request = GraphRequest.newMeRequest(accessToken, new GraphRequest.GraphJSONObjectCallback(){
#Override
public void onCompleted(JSONObject jsonObject, GraphResponse graphResponse) {
try {
email = jsonObject.getString("email");
fullName = jsonObject.getString("name");
} catch (Exception e) {
Log.d("FacebookActivity", "onCompleted - undetermined FB exception");
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email");
request.setParameters(parameters);
request.executeAsync();
}
#Override public void onCancel(){}
#Override public void onError(){}
Good luck!

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);

startActivity(intent);

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() {

Also included the profile picture field picture.width(150).height(150) as you asked

The problem here is , I am not able to get email id even after enabling Allow friends to include my email address in Download Your Information option in my facebook profile, is there any other way to get email id?
try it
String email = "";
try {
email = URLDecoder.decode(object.optString("email")
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
In my android app i have done Facebook integration.Facebook login works fine.How can i get user's email id from Facebook integration in android?
please help.
thanks in advance.
Use permission and this code
loginButton.setReadPermissions(Arrays.asList( "email","user_birthday"));
and use Graph Api
private FacebookCallback<LoginResult> mCallBack = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
progressDialog.dismiss();
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
Log.e("response: ", response + "");
Log.e("object: ", object + "");
try {
userfbData = new UserfbData();
userfbData.facebookID = object.getString("id").toString();
userfbData.email = object.getString("email").toString();
userfbData.name = object.getString("name").toString();
userfbData.gender = object.getString("gender").toString();
userfbData.birthday=object.getString("birthday").toString();
PrefUtils.setCurrentUser(userfbData,LoginActivity.this);
Log.d("flist","flist"+ userfbData.flist);
}catch (Exception e){
e.printStackTrace();
}
// Toast.makeText(LoginActivity.this,"welcome "+userfbData.name+userfbData.email+userfbData.gender+userfbData.birthday, Toast.LENGTH_LONG).show();
Toast.makeText(LoginActivity.this,"welcome "+ userfbData.name, Toast.LENGTH_LONG).show();
Intent intent=new Intent(LoginActivity.this,LogoutActivity.class);
startActivity(intent);
finish();
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
#Override
public void onCancel() {
progressDialog.dismiss();
}
#Override
public void onError(FacebookException e) {
progressDialog.dismiss();
Log.d("error","error"+e);
e.printStackTrace();
}
};
UserFbData
public class UserfbData {
public String name;
public String email;
public String facebookID;
public String gender;
public String birthday;
}
You need to make a GraphRequest call to get personal information of the logged in user such as id, name, email etc.
GraphRequest request = GraphRequest.newMeRequest(accessToken,
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject object, GraphResponse response) {
try {
String email = object.getString("email");
} catch (JSONException e) {
}
}
}
);
Bundle parameters = new Bundle();
parameters.putString("fields","email");
request.setParameters(parameters);
request.executeAsync();
I'm using Facebook SDK 4.16.1 by using Profile I could get first name, last name, name and id my code is like this
public class LoginActivity extends Activity {
String id, fname, lname, email, name, gender, locale, verified;
private CallbackManager callbackManager;
private AccessTokenTracker accessTokenTracker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.loginactivity);
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
accessTokenTracker = new AccessTokenTracker() {
#Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList(Constants.FACEBOOK_PERMISSIONS));
FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();
FB_TOKEN=loginResult.getAccessToken().getToken();
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
response.getError();
Log.e("JSON:", object.toString());
try {
email = object.getString("email");
gender = object.getString("gender");
locale = object.optString("locale");
verified = object.optString("verified");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,birthday,first_name,last_name,email,gender,verified,locale");
request.setParameters(parameters);
request.executeAsync();
id = profile.getId();
fname = profile.getFirstName();
lname = profile.getLastName();
name = profile.getName();
nextActivity(profile);
Toast.makeText(getApplicationContext(), "Logging in...", Toast.LENGTH_SHORT).show();
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
}
};
loginButton.registerCallback(callbackManager, callback);
}
}
My constants looks like this
public static final String[] FACEBOOK_PERMISSIONS = new String[] {
"public_profile",
"user_friends",
"email" };
I'm trying to get the email, gender, locale and if its already verified. How will I get the other information? Mine are always null expect for the items that is get by Profile
Update
I update my GraphRequest like this
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
response.getError();
Log.e("JSON-RESULT:", object.toString());
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(object.toString());
email = jsonObject.getString("email");
gender = jsonObject.getString("gender");
locale = jsonObject.getString("locale");
verified = jsonObject.getString("verified");
Log.e(TAG, email + " This is the email");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,birthday,first_name,last_name,email,gender,verified,locale");
request.setParameters(parameters);
request.executeAsync();
In my Logcat it shows that I set the email and the others correctly but it doesn't go inside GraphRequest when you put breakpoints, and because of this my global variable email is still null. Even if in Log.e("JSON:", object.toString()); and Log.e(TAG, email + " This is the email"); it shows I get and set the values. I'm wondering how can I get the values of Bundle?
Try using below code to fetch other info.....
private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
// Log.d("Login", "onSuccess");
GraphRequest.newMeRequest(
loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(JSONObject me, GraphResponse response) {
if (response.getError() != null) {
// handle error
} else {
email = me.optString("email");
String id = me.optString("id");
String email=me.optString("email");
String name= me.optString("name");
String gender= me.optString("gender");
String verified= me.optBoolean("is_verified") + "";
}
}
}).executeAsync();
}
#Override
public void onCancel () {
// Log.d("Login", "onCancel");
}
#Override
public void onError (FacebookException e){
// Log.d("Login", "onError " + e);
}
};
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

}
});
final Bundle parameters = new Bundle();

#Override

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.
