Android支付接入（八）：Amazon亚马逊支付

下面跟大家一起走一遍Amazon亚马逊的支付，亚马逊目前刚把业务拓展到大陆市场，但这并不代表Amazon支付不成熟，恰恰相反，Amazon的支付流程，支付结果获取及测试另人称赞，支付流程、测试流程简洁可靠。不想国内三个运营商，典型的国企，支付成功与否的判断标准仅仅是看短信是否发送出去，连个二次握手都没有，更没有安全可靠之说。在此并无他意，只是在对比运营商支付跟其他支付后的感触。但不可否认的是运营商支付在大陆移动付费端堪称龙头，尽管它并不安全，这就是现状。。。

     好了，废话说多了也没用，看看Amazon支付流程：

     申请Amazon开发者帐号->添加新应用程序->添加应用程序内商品（消费类商品，授权类商品，订阅类商品）->导出JSON数据文件->集成Amazon支付->将导出的JSON文件copy到/mnt/sdcard/amazon.sdktester.json目录下->测试支付及修改直到通过测试->上架

   Amazon官方提供的支付通信流程图：

一：导出JSON数据文件如下：（填写了几个应用内商品导出的JSON文件就包含几个计费点）

二：drawable-hdpi文件夹中最好放置高分辨率的桌面图片（建议512*512），因为Kindle fire设备有个旋转菜单，96*96分辨率在上边太模糊。

三：做本地测试时必须安装AmazonSDKTester.apk，文件位置在：http://pan.baidu.com/share/link?shareid=2085409847&uk=473193131解压Apps-SDK，如下：

四：本地测试支付成功后，订阅商品可以在AmazonSDKTester.apk中查看：

下边来看下代码实现：

     1. Manifest.xml中注册Amazon广播接收器：

<receiver android:name = "com.amazon.inapp.purchasing.ResponseReceiver" >

<intent-filter>

<action android:name = "com.amazon.inapp.purchasing.NOTIFY"

android:permission = "com.amazon.inapp.purchasing.Permission.NOTIFY"/>

</intent-filter>

</receiver>

程序中配置：

@Override

protected void onStart() {

// TODO Auto-generated method stub

super.onStart();

PurchasingManager.registerObserver(new MyObserver(MainActivity.this));

}

2.添加jar包，一下是路径或者直接从源码中copy

     3.将导出的JSON文件copy到/mnt/sdcard/amazon.sdktester.json目录下

private void copyDataBase () throws IOException{

InputStream myInput = getAssets ().open ("amazon.sdktester.json");

String outFileName = path;

OutputStream myOutput = new FileOutputStream (outFileName);

byte[] buffer = new byte[1024];

int length;

while ((length = myInput.read (buffer)) > 0){

myOutput.write (buffer, 0, length);

}

myOutput.flush ();

myOutput.close ();

myInput.close ();

}

4.安装AmazonSDKTester.apk

5.调用支付接口

PurchasingManager.initiatePurchaseRequest("qht200catcapcoin");

     6.添加支付回调：

class MyObserver extends BasePurchasingObserver{

public MyObserver(Context arg0) {

super(arg0);

// TODO Auto-generated constructor stub

}

@Override

public void onItemDataResponse(ItemDataResponse arg0) {

// TODO Auto-generated method stub

super.onItemDataResponse(arg0);

}

@Override

public void onPurchaseResponse(PurchaseResponse arg0) {

// TODO Auto-generated method stub

super.onPurchaseResponse(arg0);

switch (arg0.getPurchaseRequestStatus()) {

case SUCCESSFUL:

final Receipt receipt = arg0.getReceipt();

switch (receipt.getItemType()) {

//消耗品

case CONSUMABLE:

new AlertDialog.Builder(MainActivity.this).setTitle("支付成功").setMessage("成功购                                      买"+productName).setPositiveButton("确定", null).show();

break;

//授权内容,支付成功

case ENTITLED:

new AlertDialog.Builder(MainActivity.this).setTitle("支付成功").setMessage("成功激活正                                 版游戏").setPositiveButton("确定", null).show();

break;

//订阅内容,支付成功

case SUBSCRIPTION:

break;

}

break;

case ALREADY_ENTITLED:

//已经授权过的，属于成功，此时将道具给玩家即可

break;

case FAILED:

Toast.makeText(MainActivity.this, "支付失败", Toast.LENGTH_LONG).show();

break;

case INVALID_SKU:

Toast.makeText(MainActivity.this, "无法识别的sku", Toast.LENGTH_LONG).show();

break;

}

}

@Override

public void onGetUserIdResponse(GetUserIdResponse arg0) {

// TODO Auto-generated method stub

super.onGetUserIdResponse(arg0);

}

@Override

public void onSdkAvailable(boolean arg0) {

// TODO Auto-generated method stub

super.onSdkAvailable(arg0);

}

}

       以上就是Amazon亚马逊支付的接入流程，很简洁。等游戏发布到Amazon后才可以看到正式付费，但正式付费跟测试付费显示效果是一样的。如有任何疑问，请留言。
