安装 Facebook 应用程序时 Facebook 登录崩溃

Question

I tried to implement Facebook login in my android app with the latest facebook SDK version. While it is working for mobile phones with facebook app not installed, but the facebook login is crashing while the phone has facebook app installed with the error as

2019-12-12 14:06:27.321 19494-19523/com.abc.xyz E/GraphResponse: {HttpStatus: 400, errorCode: 100, subErrorCode: 33, errorType: GraphMethodException, errorMessage: Unsupported get request. Object with ID '572893573534105' does not exist, cannot be loaded due to missing permissions, or does not support this operation.

My facebook-login code is ->

var callbackManager: CallbackManager? = null
callbackManager = CallbackManager.Factory.create()
LoginManager.getInstance().registerCallback(callbackManager,
    object : FacebookCallback<LoginResult?> {
        override fun onSuccess(loginResult: LoginResult?) { // App code

        }

        override fun onCancel() { // App code

        }

        override fun onError(exception: FacebookException) { // App code
        }
    })

Any help is very much appreciated

    implementation 'com.facebook.android:facebook-share:5.5.1'

java File

 public void connectToFacebook() {
        if (LoginManager.getInstance() != null) {
            LoginManager.getInstance().logOut();
            LoginManager.getInstance().registerCallback(manager,
                    new FacebookCallback<LoginResult>() {
                        @Override
                        public void onSuccess(LoginResult loginResult) {
                            Log.e(TAG, "onSuccess : LoginResult" + loginResult.toString());
                            getAccountDetails(loginResult);
                        }

                            Log.e(TAG, "onError: Something wrong to connect to facebook" + error.getMessage());
                        }
                    });

            //login with permission.
            LoginManager.getInstance().logInWithPublishPermissions(this, Arrays.asList("manage_pages", "publish_pages", "publish_to_groups"));
        } else {
            Log.i(TAG, "connectToFacebook: LoginManager is Null");
        }
    }



public void getAccountDetails(final LoginResult loginResult) {

    if (loginResult != null && loginResult.getAccessToken() != null) {

        GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(JSONObject object, GraphResponse response) {

                String accountDetailsResponse = String.valueOf(object);
                Log.i(TAG, "onCompleted: AccountDetailsResponse: " + accountDetailsResponse);


            }
        });

        Bundle permission_param = new Bundle();
        permission_param.putString("fields", "id, accounts, name, email, picture.width(120).height(120)");
        request.setParameters(permission_param);
        request.executeAsync();

    } else {
        Log.e(TAG, "onCancel: loginResult or AccessToken is null");
    }
