Android Google In-App Payments (integrated version of Google Pay)

preface

I wrote a previous article about integrating Google Pay with AIDL, so check it out if you need to. However, it is not recommended. Why? Because Google docs recently said that it no longer supports the AIDL approach. So today we will talk about the new Google Pay inheritance method, of course, we only talk about the integration method here, configuration can see the Official Google(in-app payment) documentation.

The preparatory work

What are the preparations for integrating With Google Pay?

1, mobile phone installed __Google services __(of course for domestic users, foreign believe most have Google services);
2. A Google account with a credit card;
3. Google Play client;
4. Google Play Console (for configuring in-app product information)

First of all,

What do we need to do after we’ve done all the prep work? Of course, you can configure the relevant app and product information on the Google Play Console. For details, see Google Pay Configuration.

1. Payment process description

Note about the process of Google Pay: 1> Prerequisites

Check whether your package name and signature file are consistent with the APK package uploaded on Google Console. 2. Check whether the version number is consistent with the APK version released by Google Console. Whether the phone has Google serviceCopy the code

2> Payment process

2. The second step, after the initialization is successful, call the query purchase operation, the query is successful, call the consumption operation, to prevent the situation that cannot be purchased. 3. 5. The fifth step is to get the relevant information returned by Google Pay and verify the operation on the server. 6. The sixth step, the server gets the relevant information uploaded by you and carries out interactive verification with Google Pay. After successful verification, Google will deliver the goods and the server will return the relevant information to youCopy the code

2. Integrate by first adding an online dependency on Google Pay to your project’s build.gradle file
```
Implementation 'com. Android. Billingclient: billing: 3.0.0'Copy the code
```

Note: I used version 2.1.0, you can check the latest version on the official website

The second

The above is the prerequisite for access, and the following is the specific code

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

//订单号
private String mOrderID;
//用户信息
privata String mUserID;
//商品集合
private WeakReference<Activity> mActivityRef;
//回调
private OnRechargeStateListener mListener;
//商品
private String mSku;
private String goods_number;//  商品ID，游戏提供
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;
}

  public GooglePlayHelper(Activity activity, int mPayTest) {
    this.mActivityRef = new WeakReference<>(activity);
    this.mPayTest = mPayTest;
