Android Stripe 应用程序在添加新支付来源时崩溃

Question

我正在尝试使用此文档在 android 中使用 stripe SDK 实现上述结帐流程 https://stripe.com/docs/mobile/android/customer-information .我创建了一个返回临时 key 的后端调用，如下所示

{
    "id": "ephkey_EPHEMERAL_KEY_HERE",
    "object": "ephemeral_key",
    "associated_objects": [
        {
            "id": "cus_CUSTOMER_ID_HERE",
            "type": "customer"
        }
    ],
    "created": 1535352558,
    "expires": 1535356158,
    "livemode": true,
    "secret": "ek_live_SECRET_HERE"
}

在我的应用中，正在初始化我的 CustomerSession 并像这样启动 PaymentMethodsActivity

CustomerSession.initCustomerSession(
                new MyEphemeralKeyProvider(
                        new MyEphemeralKeyProvider.ProgressListener() {
                            @Override
                            public void onStringResponse(String string) {

                                if (string.startsWith("Error: ")) {
                                    new android.support.v7.app.AlertDialog.Builder(SelectCardActivity.this).setMessage(string).show();
                                }

                                Intent payIntent = PaymentMethodsActivity.newIntent(SelectCardActivity.this);
                                startActivityForResult(payIntent, REQUEST_CODE_SELECT_SOURCE);
                            }
                        }));

然后我有这个 onActivityResult 方法

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == REQUEST_CODE_SELECT_SOURCE && resultCode == RESULT_OK) {
            String selectedSource = data.getStringExtra(PaymentMethodsActivity.EXTRA_SELECTED_PAYMENT);
            Source source = Source.fromString(selectedSource);
            // This is the customer-selected source.
            // Note: it isn't possible for a null or non-card source to be returned at this time.
        }
    }

它打开 PaymentMethodsActivity 正常，并在添加新的付款方式时，当我尝试提交应用程序崩溃时出现以下堆栈跟踪。我可能错过了什么？

Answer 1

它提示您没有使用可发布的 key 初始化 PaymentConfiguration 对象。

PaymentConfiguration.init(<<YOUR PUBLISHABLE KEY HERE>>);
