应用程序在“点击付款"中不可见 [英] Application not visible in Tap and Pay

问题描述

在NFC HCE应用程序中进行调整以使其在NFC Tap and Pay设置下可见的关键是什么

What is the key thing to adjust in NFC HCE application to get it visible under settings NFC Tap and Pay

以下代码为该应用返回true，因此可以付款:

Following code returns true for the app, so it's capable of payment:

boolean isDefault = CardEmulation
                .getInstance(NfcAdapter.getDefaultAdapter(this))
                .isDefaultServiceForCategory(
                        new ComponentName(this, MyPaymentService.class),
                        CardEmulation.CATEGORY_PAYMENT);

清单中的服务声明:

<service
    android:name="my.package.MyPaymentService"
    android:exported="true"
    android:permission="android.permission.BIND_NFC_SERVICE" >
    <intent-filter>
        <action android:name="android.nfc.cardemulation.action.HOST_APDU_SERVICE" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>

    <meta-data
        android:name="android.nfc.cardemulation.host_apdu_service"
        android:resource="@xml/apduservice" />
</service>

apduservice:

apduservice:

<host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:requireDeviceUnlock="true" >

    <aid-group
        android:category="payment"
        android:description="@string/paymentGroup" >
        <aid-filter
            android:name="325041592E5359532E4444463031"
            android:description="@string/ppse" />
        <aid-filter
            android:name="A0000000041010"
            android:description="@string/mastercard" />
        <aid-filter
            android:name="A0000000031010"
            android:description="@string/visa" />
        <aid-filter
            android:name="A000000003101001"
            android:description="@string/visa" />
        <aid-filter
            android:name="A0000002771010"
            android:description="@string/interac" />
    </aid-group>

</host-apdu-service>

我丢失了一些东西，但不确定将其放置在何处.

I'm missing something but not sure what and where to put it.

谢谢.

推荐答案

HCE应用程序必须才能显示在Tap-and-pay菜单中，以便显示在Tap-and-pay菜单中.您可以使用android:apduServiceBanner属性将图形包含在host-apdu-service XML中:

In order to be shown in the tap-and-pay menu, a HCE app must provide a banner graphic. You would include the graphic into the host-apdu-service XML using the android:apduServiceBanner attribute:

<host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:requireDeviceUnlock="true"
    android:apduServiceBanner="@drawable/servicebanner">

    <aid-group android:category="payment"
               android:description="@string/paymentGroup" >
        <aid-filter ... />
    </aid-group>
</host-apdu-service>

服务标语应为尺寸为260 x 96像素的图形文件(例如.png文件).

The service banner should be a graphic file (e.g. a .png file) with dimensions of 260 x 96 pixels.
