我正在尝试[使用Xamarin在Android项目中实现亚马逊应用内购买。
设置的
亚马逊的官方Xamarin SDK不支持较新的64位设备，因此我使用Amazon的Java SDK创建了自己的Java库绑定。(Java 版本的文档(
Xamarin 为PurchasingService生成的绑定如下所示：
namespace Com.Amazon.Device.Iap
{
[Register ("com/amazon/device/iap/PurchasingService", DoNotGenerateAcw = true)]
public sealed class PurchasingService : Object
{
//
// Static Fields
//
private static IntPtr IS_SANDBOX_MODE_jfieldId;
[Register ("SDK_VERSION")]
public const string SdkVersion = "2.0.76.4";
internal static IntPtr java_class_handle;
private static IntPtr id_getUserData;
private static IntPtr id_getProductData_Ljava_util_Set_;
private static IntPtr id_getPurchaseUpdates_Z;
private static IntPtr id_notifyFulfillment_Ljava_lang_String_Lcom_amazon_device_iap_model_FulfillmentResult_;
private static IntPtr id_purchase_Ljava_lang_String_;
private static IntPtr id_registerListener_Landroid_content_Context_Lcom_amazon_device_iap_PurchasingListener_;
//
// Static Properties
//
internal static IntPtr class_ref {
get;
}
[Register ("IS_SANDBOX_MODE")]
public static bool IsSandboxMode {
get;
}
public static RequestId UserData {
[Register ("getUserData", "()Lcom/amazon/device/iap/model/RequestId;", "GetGetUserDataHandler")]
get;
}
//
// Properties
//
protected override IntPtr ThresholdClass {
get;
}
protected override Type ThresholdType {
get;
}
//
// Constructors
//
internal PurchasingService (IntPtr javaReference, JniHandleOwnership transfer);
//
// Static Methods
//
[Register ("getProductData", "(Ljava/util/Set;)Lcom/amazon/device/iap/model/RequestId;", "")]
public static RequestId GetProductData (ICollection<string> p0);
[Register ("getPurchaseUpdates", "(Z)Lcom/amazon/device/iap/model/RequestId;", "")]
public static RequestId GetPurchaseUpdates (bool p0);
[Register ("notifyFulfillment", "(Ljava/lang/String;Lcom/amazon/device/iap/model/FulfillmentResult;)V", "")]
public static void NotifyFulfillment (string p0, FulfillmentResult p1);
[Register ("purchase", "(Ljava/lang/String;)Lcom/amazon/device/iap/model/RequestId;", "")]
public static RequestId Purchase (string p0);
[Register ("registerListener", "(Landroid/content/Context;Lcom/amazon/device/iap/PurchasingListener;)V", "")]
public static void RegisterListener (Context p0, IPurchasingListener p1);
}
}
对于PurchasingListener接口：
namespace Com.Amazon.Device.Iap
{
[Register ("com/amazon/device/iap/PurchasingListener", "", "Com.Amazon.Device.Iap.IPurchasingListenerInvoker")]
public interface IPurchasingListener : IJavaObject, IDisposable
{
//
// Methods
//
[Register ("onProductDataResponse", "(Lcom/amazon/device/iap/model/ProductDataResponse;)V", "GetOnProductDataResponse_Lcom_amazon_device_iap_model_ProductDataResponse_Handler:Com.Amazon.Device.Iap.IPurchasingListenerInvoker, AmazonIAP")]
void OnProductDataResponse (ProductDataResponse p0);
[Register ("onPurchaseResponse", "(Lcom/amazon/device/iap/model/PurchaseResponse;)V", "GetOnPurchaseResponse_Lcom_amazon_device_iap_model_PurchaseResponse_Handler:Com.Amazon.Device.Iap.IPurchasingListenerInvoker, AmazonIAP")]
void OnPurchaseResponse (PurchaseResponse p0);
[Register ("onPurchaseUpdatesResponse", "(Lcom/amazon/device/iap/model/PurchaseUpdatesResponse;)V", "GetOnPurchaseUpdatesResponse_Lcom_amazon_device_iap_model_PurchaseUpdatesResponse_Handler:Com.Amazon.Device.Iap.IPurchasingListenerInvoker, AmazonIAP")]
void OnPurchaseUpdatesResponse (PurchaseUpdatesResponse p0);
[Register ("onUserDataResponse", "(Lcom/amazon/device/iap/model/UserDataResponse;)V", "GetOnUserDataResponse_Lcom_amazon_device_iap_model_UserDataResponse_Handler:Com.Amazon.Device.Iap.IPurchasingListenerInvoker, AmazonIAP")]
void OnUserDataResponse (UserDataResponse p0);
}
}
我还确保 Android 清单已修改为：
<receiver android:name = "com.amazon.device.iap.ResponseReceiver" >
<intent-filter>
<action android:name = "com.amazon.inapp.purchasing.NOTIFY"
android:permission = "com.amazon.inapp.purchasing.Permission.NOTIFY" />
</intent-filter>
</receiver>
亚马逊应用测试器安装在我的 Kindle 上，并配置了以下测试数据：
{
"IAP_ID":
{
"description":"One year Subscription",
"title":"My Subscription",
"itemType":"SUBSCRIPTION",
"price":20.00,
"subscriptionParent":"org.company.appid"
}
}
我有一个类的骨架来测试系统是否正常工作：
public class AmazonIAPController : Java.Lang.Object, IPurchasingListener
{
const string ProductId = "IAP_ID";
private Activity uiActivity;
public AmazonIAPController()
{
}
public void SetupIAP(Activity activity) {
uiActivity = activity;
PurchasingService.RegisterListener(uiActivity, this);
// test that the Amazon system works
PurchasingService.Purchase(ProductId);
}
public void OnResume(Activity activity) {
uiActivity = activity;
PurchasingService.RegisterListener(uiActivity, this);
//PurchasingService.UserData;
PurchasingService.GetPurchaseUpdates(false);
PurchasingService.GetProductData(new string[] { ProductId });
}
public void OnProductDataResponse(ProductDataResponse response) {
var status = response.GetRequestStatus();
Debug.WriteLine("*****OnProductDataResponse");
}
public void OnPurchaseResponse(PurchaseResponse response) {
var status = response.GetRequestStatus();
Debug.WriteLine("*****OnPurchaseResponse");
}
public void OnPurchaseUpdatesResponse(PurchaseUpdatesResponse response) {
var status = response.GetRequestStatus();
Debug.WriteLine("*****OnPurchaseUpdatesResponse");
}
public void OnUserDataResponse(UserDataResponse response) {
var status = response.GetRequestStatus();
Debug.WriteLine("*****OnUserDataResponse");
}
}
测试运行
我正在尝试在我的第 5 代 Kindle Fire 上运行它。当应用程序启动时，系统会按预期提示用户 Amazon IAP 提示。如果执行了购买，则交易会完成，并且交易会正确显示在亚马逊应用程序测试器应用程序中。
问题所在
我在回调方法中设置了断点。这些断点永远不会触发。Debug.WriteLine调用也不会显示在应用程序输出中。似乎没有调用我的回调方法。
问题的根源是 Android 清单条目与 Xamarin 生成具有代码属性的清单条目的方式冲突。
为了解决此问题，我从清单中删除了上述条目，并在 Java 绑定项目中创建了一个添加文件，其中包含ResponseReciever的部分类和相关清单属性，如下所示：
using System;
using Android.App;
using Android.Content;
namespace Com.Amazon.Device.Iap
{
[BroadcastReceiver(Name = "com.amazon.device.iap.ResponseReceiver")]
[IntentFilter(new[] { "com.amazon.inapp.purchasing.NOTIFY" })]
public partial class ResponseReceiver
{
}
}
在此之后，正确生成清单条目，预期的回调开始工作。
注意：
您可能会注意到清单 XML 中的android:permission条目不在上述属性中。我找不到参考，但我记得在某处看到，不仅不需要此条目来使SDK工作，而且根据官方Android文档，它实际上不是action上的有效属性。
