I'm trying to get the user's email address once he's logged into my Android app with Facebook (sdk 4.0). I've read many posts asking the same thing but I still couldn't make it work. I simply log the user in with the code
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "user_friends", "email"));
Then I make the Graph API request with
LoginManager.getInstance().registerCallback(fbCallbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
System.out.println(loginResult.getAccessToken().toString());
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
System.out.println(object.toString());
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "email");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
}
});
The output is just
{AccessToken token:ACCESS_TOKEN_REMOVED permissions:[public_profile, contact_email, user_friends, email, basic_info]}
{"id":"xxxxxxxxxxxxxxx"}
Even if I remove the "fields" part, I get a JSON with a bunch of the user's public info, but never the email field. I'm testing this on my own Facebook account, and I do have an email address associated to it.
Click the arrow in the upper-right corner of your news feed and select "Account Settings." Your email address is listed under General Account Settings.
The simplest way to get a copy of the User Profile object is to access the /me endpoint: FB. api('/me', function(response) { }); This will this will return the users name and an ID by default.
You can get user data by using the Facebook Graph API if the user has given their permission to share their data and your app has the appropriate permissions to receive this data. This topic shows you how to make a single request for data and how to have a batch of requests in a single request.
Here is the complete code through which i get all the data we need from facebook
login_facebook_button = (LoginButton) findViewById(R.id.login_facebook_button);
login_facebook_button.setReadPermissions(Arrays.asList("public_profile", "user_friends", "email", "user_birthday"));
//LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "user_friends"));
// Callback registration
login_facebook_button.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
Log.e("onSuccess", "--------" + loginResult.getAccessToken());
Log.e("Token", "--------" + loginResult.getAccessToken().getToken());
Log.e("Permision", "--------" + loginResult.getRecentlyGrantedPermissions());
Profile profile = Profile.getCurrentProfile();
Log.e("ProfileDataNameF", "--" + profile.getFirstName());
Log.e("ProfileDataNameL", "--" + profile.getLastName());
Log.e("Image URI", "--" + profile.getLinkUri());
Log.e("OnGraph", "------------------------");
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
Log.e("GraphResponse", "-------------" + response.toString());
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,gender,birthday,email");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
}
});
And the response of the call in log is:
{Response: responseCode: 200, graphObject: {"id":"896337040431723","name":"Aneh Thakur","link":"https:\/\/www.facebook.com\/app_scoped_user_id\/896337040431723\/","gender":"male","birthday":"08\/05\/1992","email":"[email protected]"}, error: null}
Hope this will help you.
You can get the logged user email as follows , But note that ,
They do not guaranteed you will get an email address read here .
In some cases, though user has provided an email, it will not come through request, if the email is not valid.
@Override
public void onSuccess(LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest( AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object,GraphResponse response) {
try {
String email=object.getString("email");
Log.d(TAG + "user email ", email);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
request.executeAsync();
}
fbLoginButton.setReadPermissions("public_profile", "user_friends", "user_photos", "email", "user_birthday", "public_profile", "contact_email");
"contact_email" is the email permission, i was missing that when i added it to i got the things working.
