Google内购--封装版

最近老大提出了一个需求，在应用里面加一个内购。由于之前没做过这块，所以百度一番。网上都是讲的使用一大堆的utils、还要加一个aidl文件。感觉挺麻烦的。最终让我找到了：com.android.billingclient:billing:1.0 。使用该依赖，解决了一大堆的utils。

好了，开始介绍下使用步骤：

一、代码部分

①、在AndroidManifest.xml中添加内购权限。

<uses-permission android:name="com.android.vending.BILLING" />

这个是必须的。

②、加入依赖。

compile 'com.android.billingclient:billing:1.0'
//如果用到isGooglePlayServicesAvailable方法需要导入这个包，这个方法也可以去掉。implementation 'com.google.android.gms:play-services-basement:11.8.0'

③、代码封装：

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.support.annotation.Nullable;
import android.util.Log;import com.android.billingclient.api.BillingClient;

Intent("com.android.vending.billing.InAppBillingService.BIND");intent.setPackage("com.android.vending");return intent;}
}

代码可以直接拿去用的，不需要填入key值。

④、代码示例：

private GoogleBillingUtil googleBillingUtil = null;
private MyOnPurchaseFinishedListener mOnPurchaseFinishedListener = new MyOnPurchaseFinishedListener();//购买回调接口
private MyOnQueryFinishedListener mOnQueryFinishedListener = new MyOnQueryFinishedListener();//查询回调接口
private MyOnStartSetupFinishedListener mOnStartSetupFinishedListener = new OnStartSetupFinishedListener();//启动结果回调接口

4.1：创建示例,需要在build之前设置回调接口,接口可以选择性设置

@Override
protected void onStart() {super.onStart();/*建议放在onStart里面初始化，因为你可能在别的页面与谷歌服务断开了连接或者设置了接口，所以当一个页面打开的时候，你应该重新检测连接是否正常(如果断开则重新连接)并重新设置接口*/googleBillingUtil = GoogleBillingUtil.getInstance().setOnPurchaseFinishedListener(mOnPurchaseFinishedListener).setOnQueryFinishedListener(mOnQueryFinishedListener).setOnStartSetupFinishedListener(mOnStartSetupFinishedListener).build();
}

4.2：发起内购或者订阅

public void queryInventoryInApp() 查询内购商品信息列表
public void queryInventorySubs() 查询订阅商品信息列表
public void purchaseInApp(Activity activity,String skuId) 发起内购
public void purchaseSubs(Activity activity,String skuId) 发起订阅

4.3：清除监听

//如果下个页面或者上个页面没有使用到googleBuillingUtil.getInstance()，那么就需要在finish或者startActivity之前调用cleanListener()方法，来清除接口。
//可以尝试这样
@Overridepublic void onBackPressed() {GoogleBillingUtil.cleanListener();super.onBackPressed();}
//返回键点击
public void onBackClick(){GoogleBillingUtil.cleanListener();this.finish();}//如果只使用一次googleBuillingUtil，可以选择使用endConnection()方法断开google服务的连接，下次使用重新连接。

4.4：接口说明

//查询商品信息回调接口
private class MyOnQueryFinishedListener implements GoogleBillingUtil.OnQueryFinishedListener
{@Overridepublic void onQuerySuccess(String skuType,List<SkuDetails> list) {//查询成功，返回商品列表，//skuDetails.getPrice()获得价格(文本)//skuDetails.getType()获得类型 sub或者inapp,因为sub和inapp的查询结果都走这里，所以需要判断。//googleBillingUtil.getSubsPositionBySku(skuDetails.getSku())获得当前subs sku的序号//googleBillingUtil.getInAppPositionBySku(skuDetails.getSku())获得当前inapp suk的序号}@Overridepublic void onQueryFail(int responseCode) {//查询失败}@Overridepublic void onQueryError() {//查询错误}
}
//服务初始化结果回调接口
private class MyOnStartSetupFinishedListener implements GoogleBillingUtil.OnStartSetupFinishedListener
{
//...;
}
//购买商品回调接口
private class MyOnPurchaseFinishedListener implements GoogleBillingUtil.OnPurchaseFinishedListener
{@Overridepublic void onPurchaseSuccess(List<Purchase> list) {//内购或者订阅成功,可以通过purchase.getSku()获取suk进而来判断是哪个商品}@Overridepublic void onPurchaseFail(int responseCode) {}@Overridepublic void onPurchError() {}
}

4.5：api说明：

//初始化
1、public static GoogleBillingUtil getInstance() 获取单实例
2、public GoogleBillingUtil build() 创建内购实例，连接谷歌支付服务(如果未创建、未连接)，并查询商品信息列表。如果默认自动消耗已内购但未被消耗的商品，可以通过设置isAutoConsumeAsync改变。
3、public void startConnection() 连接谷歌支付服务(一般情况下不需要手动调用，build的时候已经调用了)//查询、购买与消耗
4、public void queryInventoryInApp() 查询内购商品信息列表
5、public void queryInventorySubs() 查询订阅商品信息列表
6、public void purchaseInApp(Activity activity,String skuId) 发起内购
7、public void purchaseSubs(Activity activity,String skuId) 发起订阅
8、public void consumeAsync(String purchaseToken) 消耗商品(一般情况下不需要手动调用，内购的时候自动调用了)//购买历史、有效订阅数
9、public List<Purchase> queryPurchasesInApp() 获取已经内购的商品列表
10、public List<Purchase> queryPurchasesSubs() 获取已经订阅的商品列表
11、public int getPurchasesSizeSubs() 获取有效订阅的数量(-1查询失败，0没有有效订阅，>0具有有效的订阅)//便捷工具
12、public int getSubsPositionBySku(String sku) 通过sku获取订阅商品序号
13、public int getInAppPositionBySku(String sku) 通过sku获取内购商品序号
14、public String getSubsSkuByPosition(int position) 通过序号获取订阅sku
15、public String getInAppSkuByPosition(int position) 通过序号获取内购sku
16、private String getSkuType(String sku) 通过sku获取商品类型(订阅获取内购)inapp内购，subs订阅//接口设置
17、public GoogleBillingUtil setOnPurchaseFinishedListener(OnPurchaseFinishedListener onPurchaseFinishedListener) 购买回调接口
18、public GoogleBillingUtil setOnQueryFinishedListener(OnQueryFinishedListener onQueryFinishedListener) 商品信息查询接口
19、public GoogleBillingUtil setOnStartSetupFinishedListener(OnStartSetupFinishedListener onStartSetupFinishedListener) 服务初始化结果回调接口 //其他、内存
20、public void setIsAutoConsumeAsync(boolean isAutoConsumeAsync) 设置是否自动消耗商品
21、public static void cleanListener() 清除所有监听器，避免内存泄漏，回调错乱等问题。
22、public static void endConnection() 断开连接google服务（一般情况不建议调用该方法，让google保留连接是最好的选择。）

二、googleplay操作部分：

当你把代码添加完成后，可以在代码中添加一个skuid :(由字母和数字组成，例如weather_54).private String[] inAppSKUS = new String[]{"weather_54","",""},这个要与googlePlay应用内商品栏的添加商品一栏对应。然后打包apk.

①、翻墙上传应用，应用上传部分这里不做详细讲解。可以先上传一个内部测试版本。内部测试版本支付不会扣除金额。如下图所示：

我这里上传的是alpha测试版本，可以添加测试人员。当完成apk上传之后，会生成一个测试版本的googleplay下载地址。

②、应用内商品

当你的应用存在需要google登录或者其他使用到签名的位置的话，记住：千万不要选择应用签名！千万不要选择应用签名！千万不要选择应用签名！。它会覆盖你的签名。而且不可逆操作。

需要你填写一些信息，例如银行卡之类的。这里公司已经填好了。

③、添加商品：

还记得那个skuid么，对。就是这个Id名称。

④、开始填写定价内容：

红框里面的内容可以更改。

好了。保存更改后。就可以进行测试了。如果你的代码以及googleplay应用都ok的话。点击支付，就可以看到如下图所示：

文章就到这里了。有疑问随时可以@我~~~~thanks
