google内购In-App Billing

开发环境eclipse，下载内购需要的文件sdkManager,windows>android SDK manager>Extra..

将下载文件中的

拷到src下面，代码里要用的下面文件

初始化

//产品ID列表
public static String[] productID_Array = {"60crystal", "300crystal", "980crystal", "1980crystal", "3280crystal", "6480crystal", "3000crystalmonth"};
//购买列表
public static Vector<Purchase> inventory_list = new Vector<Purchase>();

        String base64EncodedPublicKey = "";
        mHelper = new IabHelper(this, base64EncodedPublicKey);
        mHelper.enableDebugLogging(false);
        //执行服务绑定
        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() 
        {
            public void onIabSetupFinished(IabResult result) 
            {
                if (!result.isSuccess()) {
                    return;
                }
                //产品id列表
                List<String> productList = new ArrayList<String>();
                for(int i = 0; i < productID_Array.length; i++)
                {
                    productList.add(productID_Array[i]);    
                } 
                //记录初始化是否成功的状态
                googleplay_iap = true;
                //检索产品详细信息
                mHelper.queryInventoryAsync(true, productList, mGotInventoryListener);                
            }
        });

base64EncodedPublicKey是googleplay后台的发布产品的时候生成提供的，最好放在服务端

platformGoogleRequestItem是客户端函数，需要请求本地服务器发送游戏货币

再说测试，测试可以出个测试包上传到googleplay后台的alpha版本或者beta版本，要求签名和包名要与正式包的一样

然后添加测试账号，测试账号要绑定信用卡，开发者账户>账户明细>许可测试，这个地方也要添加测试账号，这样就不会扣钱啦。。。
