Android Facebook Login- Profile is null

Question

Trying to integrate Facebook Login in android app. The login and logout is working fine but sometimes even after login in, profile is still null. As soon as I get the details from Facebook I logout. I referred to some other questions on Stackoverflow, and applied it in the code but somewhere still something is going wrong and not able to figure it out.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.login_activity);
    callbackManager = CallbackManager.Factory.create();
    loginButton = (LoginButton) findViewById(R.id.btnFacebookSignin);
    loginButton.setReadPermissions("public_profile, email");
    loginButton.registerCallback(callbackManager, facebookCallback);
}

FacebookCallback<LoginResult> facebookCallback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {

            if(Profile.getCurrentProfile() == null) {
                mProfileTracker = new ProfileTracker() {
                    @Override
                    protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
                        Log.v("facebook - profile", profile2.getFirstName());
                        mProfileTracker.stopTracking();
                    }
                };
                mProfileTracker.startTracking();
            }
            else {
                Profile profile = Profile.getCurrentProfile();
                Log.v("facebook - profile", profile.getFirstName());
            }
            GraphRequest request = GraphRequest.newMeRequest(
                    loginResult.getAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {

                        @Override
                        public void onCompleted(JSONObject object, GraphResponse response) {

                            if (BuildConfig.DEBUG) {
                                FacebookSdk.setIsDebugEnabled(true);
                                FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

                                Profile profile = Profile.getCurrentProfile();
                                if (profile != null) {

                                    String name = profile.getName();
                                    Uri pictureUri = profile.getProfilePictureUri(200, 200);
                                    String email = object.optString("email");
                                    String uid = object.optString("id");
                                    try {
                                        sendLogin(uid, name, email, pictureUri.toString(), "fb");
                                    } catch (JSONException e) {
                                        e.printStackTrace();
                                    } catch (IOException e) {
                                        e.printStackTrace();
                                    }
                                    facebookLogout();
                                } else {
                                    facebookLogout();
                                    Toast.makeText(getApplication(), "Something went wrong, please try again later", Toast.LENGTH_LONG).show();
                                }
                            }
                        }
                    });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "email");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
        }

        @Override
        public void onError(FacebookException e) {
            Toast.makeText(getApplication(), "Something went wrong, please try again later", Toast.LENGTH_LONG).show();
        }
    };

    public void facebookLogout() {
        LoginManager.getInstance().logOut();
    }

sendLogin method just adds the received information from Facebook into the local database. — Jay Visariya, Dec 14 '15 at 06:16

Try this Code I hope Its Work..

   facebookimage(object.getString("id"));

This is Method:

 private void facebookimage(String id) {
        new getFacebookImage(id).execute();
    }

This is AsyncTask class to get Profile Image on Facebook ;

private class getFacebookImage extends AsyncTask {

        String userID;
        Bitmap camera;

        public getFacebookImage(String id) {
            userID=id;
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected Object doInBackground(Object[] params) {


            URL imageURL = null;
            Bitmap bitmap=null;
            try {
                imageURL = new URL("https://graph.facebook.com/" + userID + "/picture?type=large");
                bitmap = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            Log.e("String Image",""+bitmap);
            camera=bitmap;
            return bitmap;
        }

        @Override
        protected void onPostExecute(Object o) {
            super.onPostExecute(o);

            if(camera != null){
                Log.e("Image Load","UPload image");
                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                camera.compress(Bitmap.CompressFormat.JPEG, 100, stream);
                byte imageInByte[] = stream.toByteArray();
                String encodedImage = Base64.encodeToString(imageInByte, Base64.DEFAULT);
                DataBase.setUserImage(LoginActivity.this,encodedImage);

            }

        }
    }

I am able to get all the information required like name, email, id and profile image perfectly, but when I login sometimes I get profile is null even after logged in correctly. — Jay Visariya, Dec 14 '15 at 06:33

I am getting only id and email in onCompleted JSONObject. What could be the reason that? I am setting the necessary permission as well in onCreate. — Jay Visariya, Dec 14 '15 at 07:15

Initially I was getting only id and email in JSONObject object of onCompleted. Even though I set permissions like "public_profile" and "email" which is sufficient enough to get the id, name, email and profile picture from facebook. But somewhere I went wrong and didn't understand and added Profile and did getProfile() so I can get the name and profile picture. Then other problem arised was even after login perfectly, I was getting null profile sometimes(may be once in 5 times). For that had to put Profile Tracker and this was because Profile works Asynchronously(was too confusing for me as you have to put trackers and start & stop tracking).

Then I realized where I went wrong. In the bundle where we need to mention what all we want in the json object as reply, I had only mentioned "id". So now in the below code I added "name" and "email" as well. So in the JSONObject object response I get the name and email as well.

And for profile picture I saw How can I display the users profile pic using the facebook graph api? and implemented this using Uri builder Use URI builder in Android or create URL with variables . So with this I removed the use of Profile completely and still getting all the data I wanted.

This answer is the mixture of both the answers mentioned by Destro - Android Facebook Login- Profile is null & How to get email id From Android Facebook SDK 4.6.0?

FacebookCallback<LoginResult> facebookCallback = 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) {

                            if (BuildConfig.DEBUG) {
                                FacebookSdk.setIsDebugEnabled(true);
                                FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);


                                String uid = object.optString("id");
                                String email = object.optString("email");
                                String name = object.optString("name");

                                Uri.Builder builder = new Uri.Builder();
                                builder.scheme("https")
                                        .authority("graph.facebook.com")
                                        .appendPath(uid)
                                        .appendPath("picture")
                                        .appendQueryParameter("width", "1000")
                                        .appendQueryParameter("height", "1000");

                                Uri pictureUri = builder.build();

                                try {
                                    sendLogin(uid, name, email, pictureUri.toString(), "fb");
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                } catch (IOException e) {
                                    e.printStackTrace();
                                }
                                facebookLogout();

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

    };

    public void facebookLogout() {

this code is working for me but in signed apk its not working. I have updated release keyhash on facebook developer. please let know what I need to change. Thanks — vijay chhalotre, Aug 30 '17 at 11:05
