使用 MSAL 在原生 Android 中加载用户流的 Azure Adb2c 自定义 Web 视图

问题描述

我使用 MSAL 将 azure adb2c 集成到我的原生 android 应用程序中。目前我正在为我的应用程序使用 createSingleAccountPublicclientApplication。我已经创建了 sign-up and sign-in user flow 并与我的应用程序完美集成。当应用程序启动时，它重定向到 Web 视图，因为我在清单文件中提到了 browsertabactivity。但是根据我们的要求，我们必须创建自己的 custom webview 并显示所有 userflows 并根据需要获取回调。是否可以为 android 创建 custom webview 并显示用户流程？

第二个问题是，当用户从注册页面点击 back button 时，会抛出错误代码 AADB2C90091，而不是返回 signIn UserFlow Page 。如何在按下后显示 signIn UserFlow 页面？

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.microsoft_azure);
        context = MicrosoftAzureActivity.this;
        initializeUI();

        // Creates a PublicclientApplication object with res/raw/auth_config_single_account.json
        PublicclientApplication.createSingleAccountPublicclientApplication(MicrosoftAzureActivity.this,R.raw.auth_config_single_account,new IPublicclientApplication.ISingleAccountApplicationCreatedListener() {
                    @Override
                    public void onCreated(ISingleAccountPublicclientApplication application) {
                        /**
                         * This test app assumes that the app is only going to support one account.
                         * This requires "account_mode" : "SINGLE" in the config json file.
                         **/
                        mSingleAccountApp = application;

                        loadAccount();
                    }

                    @Override
                    public void onError(MsalException exception) {
                        displayError(exception);
                    }
                });

    }

        if (mSingleAccountApp == null) {

            return;

         mSingleAccountApp.getCurrentAccountAsync(new ISingleAccountPublicclientApplication.CurrentAccountCallback() {
            @Override
            public void onAccountLoaded(@Nullable IAccount activeAccount) {
                // You can use the account data to update your UI or your app database.
                mAccount = activeAccount;
                if (activeAccount != null) {
              mSingleAccountApp.acquiretokenSilentAsync(getScopes(),B2CConfiguration.getAuthorityFromPolicyName("B2C_1_SignInSignUp"),getAuthSilentCallback());

                }
            }

            @Override
            public void onAccountChanged(@Nullable IAccount priorAccount,@Nullable IAccount currentAccount) {
                if (currentAccount == null) {
                    // Perform a cleanup task as the signed-in account changed.
                    showToastOnSignOut();
                }
            }

            @Override
            public void onError(@NonNull MsalException exception) {
                displayError(exception);
            }
        });
    }
