Hi all,

  I am getting this error above after login to facebook from my app and facebook asks for permisssion 2 times(dont know if this is part of the exception).After that the app crashes. How to resolve this issue?

Here is the code below i have written

    @Override

    public void onFacebookLoginButtonClicked()

    {

        AccessToken token = AccessToken.getCurrentAccessToken();

        onregister();

        if (token == null) {

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

        }

        else{

            LoginManager.getInstance().logOut();

        }

    }

      @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        SharedPreferenceManager.setApplicationContext(getApplicationContext());

        onregister();

        SharedPreferenceManager.setPreference("notificationcount", 0);

    FacebookSdk.sdkInitialize(this.getApplicationContext());

        LoginButton authButton = (LoginButton)findViewById(R.id.facebook_button);

        callbackManager = CallbackManager.Factory.create();

        LoginManager.getInstance().registerCallback(callbackManager,

                new FacebookCallback<LoginResult>() {

                    @Override

                    public void onSuccess(final LoginResult loginResult) {

                        final Profile profile = Profile.getCurrentProfile();

                        SharedPreferenceManager.setPreference("id", profile.getId());

                        GraphRequest request = GraphRequest.newMeRequest(

                                AccessToken.getCurrentAccessToken(),

                                new GraphRequest.GraphJSONObjectCallback() {

                                    @Override

                                    public void onCompleted(

                                            JSONObject jsonObject,

                                            GraphResponse response) {

                                        try {

                                            email = jsonObject.getString("email");

                                            gender = jsonObject.getString("gender");

                                            if (mAuthTask == null) {

                                                mAuthTask = new UserLoginTask(email, "", profile.getName(), "facebook",profile.getId(),loginResult.getAccessToken().getToken(),gender,getRegistrationId(getApplicationContext()));

                                                //Log.v("token", loginResult.getAccessToken().getToken());

                                                mAuthTask.execute((Void) null);

                                            }

                                        } catch (JSONException exe) {

                                        }

                                    }

                                });

                        Bundle parameters = new Bundle();

                        parameters.putString("fields", "id,name,link,email,gender");

                        request.setParameters(parameters);

                        request.executeAsync();

                    }

                    @Override

                    public void onCancel() {

                        LoginManager.getInstance().logOut();

                    }

                    @Override

                    public void onError(FacebookException exception) {

                        LoginManager.getInstance().logOut();

                    }

                });

        mGoogleApiClient = buildGoogleApiClient();

        if (savedInstanceState != null) {

            mSignInProgress = savedInstanceState

                    .getInt(SAVED_PROGRESS, STATE_DEFAULT);

        }

        setContentView(R.layout.activity_main);

    }

    @Override

    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);

        callbackManager.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {

            case RC_SIGN_IN:

                if (resultCode == RESULT_OK) {

                    // If the error resolution was successful we should continue

                    // processing errors.

                    mSignInProgress = STATE_SIGN_IN;

                } else {

                    // If the error resolution was not successful or the user canceled,

                    // we should stop processing errors.

                    mSignInProgress = STATE_DEFAULT;

                }

                if (!mGoogleApiClient.isConnecting()) {

                    // If Google Play services resolved the issue with a dialog then

                    // onStart is not called so we need to re-attempt connection here.

                    mGoogleApiClient.connect();

                }

                break;

        }
