前言

之前寫(xiě)過(guò)一篇通過(guò)AIDL方式集成Google支付
的文章，如有需要，可以去看看。但是，不建議使用。為啥呢？，因?yàn)樽罱碐oogle文檔中說(shuō)已經(jīng)不再支持AIDL的方式了。所以今天就來(lái)說(shuō)說(shuō)新的Google支付繼承方式，當(dāng)然，我們這里只說(shuō)集成方式，配置可以看Google(應(yīng)用內(nèi)支付)官方文檔。

準(zhǔn)備工作

要集成Google支付的準(zhǔn)備工作有哪些呢？

• 1、手機(jī)上安裝Google服務(wù)(當(dāng)然是針對(duì)國(guó)內(nèi)的用戶，國(guó)外的相信大部分都有Google服務(wù))；
• 2、一個(gè)綁定信用卡的Google賬號(hào)；
• 3、Google play客戶端；
• 4、Google play console（用于配置應(yīng)用內(nèi)商品信息）；

首先

上面的準(zhǔn)備工作都做好了之后需要干什么呢？當(dāng)然是在Google play console上配置相關(guān)應(yīng)用和商品信息了，至于如何配置具體可以參考Google支付配置。

• 1、支付流程說(shuō)明
  關(guān)于Google支付的流程說(shuō)明：
  1>前提條件

  1、檢查你的包名和簽名文件是否和Google Console 上面上傳的apk包是否一致
  2、檢查版本號(hào)是否和Google console發(fā)布的apk版本是否一致
  3、檢查你是否可以購(gòu)買，是否綁定了銀行卡，手機(jī)支不支持Google支付，手機(jī)是否有Google服務(wù)
  

  2>支付流程

   1、第一步，初始化Google支付
   2、第二步，初始化成功后調(diào)用查詢購(gòu)買的商品操作，查詢成功調(diào)用消耗操作，防止不能購(gòu)買的情 況發(fā)生
   3、第三步，生成訂單號(hào)進(jìn)行購(gòu)買操作
   4、第四步，購(gòu)買成功后再次調(diào)用一次消耗操作（為了下次購(gòu)買可以成功）
   5、第五步，拿到Google支付返回的相關(guān)信息，在服務(wù)器進(jìn)行驗(yàn)證操作。
   6、第六步，服務(wù)器拿到你上傳的相關(guān)信息和Google支付進(jìn)行交互驗(yàn)證，驗(yàn)證成功后Google發(fā)貨，服務(wù)器給你返回相關(guān)信息

• 2、集成工作
  首先在你的項(xiàng)目的build.gradle文件中加入Google支付的在線依賴

  implementation 'com.android.billingclient:billing:3.0.0'

注意：我用的時(shí)候版本是2.1.0，你可以去官網(wǎng)查查最新的版本

其次

上面是接入的前提條件，下面看具體代碼

public class GooglePlayHelper {
private static final String TAG = GooglePlayHelper.class.getSimpleName();
private static final int GAME_ORDER_ID=0x01;

//訂單號(hào)
private String mOrderID;
//用戶信息
privata String mUserID;
//商品集合
private WeakReference<Activity> mActivityRef;
//回調(diào)
private OnRechargeStateListener mListener;
//商品
private String mSku;
private String goods_number;//  商品ID，游戲提供
private BillingClient mBillingClient;
private int mPayTest;
private String mConsume = "0";

GooglePlayHelper(Activity activity, 
                String goods_number, int mPayTest,
                 String sku, OnRechargeStateListener mListener) {
    this.mActivityRef = new WeakReference<>(activity);
    this.goods_number = goods_number;
    this.mSku = sku;
    this.mPayTest = mPayTest;
    this.mListener = mListener;
