Android : Facebook Sdk Unable to get email id

Question

I am using this for fb login :

LoginManager.getInstance().logInWithReadPermissions(FindFriendActivity.this, Arrays.asList("public_profile", "user_friends", "email"));

FacebookSdk.sdkInitialize(this.getApplicationContext());
        callbackManager = CallbackManager.Factory.create();
        LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>()
                {
                    @Override
                    public void onSuccess(LoginResult loginResult)
                    {
                        Log.d("Success", "Login");
                        GraphRequest graphRequestAsyncTask = new GraphRequest(
                                loginResult.getAccessToken(), "/me/friends", null, HttpMethod.GET, new GraphRequest.Callback()
                        {
                            public void onCompleted(GraphResponse response)
                            { 
                               JSONArray rawName = response.getJSONObject().getJSONArray("data");
                            }
                        }
                        );
                        Bundle parameters = new Bundle();
                        parameters.putString("fields", "id,name,picture,email");
                        graphRequestAsyncTask.setParameters(parameters);
                        graphRequestAsyncTask.executeAsync();
                    }

                    @Override
                    public void onCancel()
                    {
                        Utilities.ShowToast(mContext, "Facebook Login cancel");
                    }

                    @Override
                    public void onError(FacebookException exception)
                    {
                        Utilities.ShowToast(mContext, exception.getMessage());
                    }
                }
        );


@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }

So i think the only issue left is that your friends haven't grant `email` permission to your app. Have you checked this? You can't obtain all friend's emails — Beloo, Oct 14 '16 at 12:55

If you request the email permission it is not guaranteed you will get an email address. For example, if someone signed up for Facebook with a phone number instead of an email address, the email field may be empty.
