google计费接入，Billing结算库支付
谷歌计费接入文档地址：https://developer.android.com/google/play/billing/billing_overview。
因为公司的海外游戏策略变更，需要接入google支付，让土豪用户直接付钱，没钱的就看广告嘛。我们没有采用google钱包，只是用Google的结算库版本，因为我们公司没有申请为google的商户。
1.添加google billing库的依赖
implementation 'com.android.billingclient:billing:2.1.0'2.初始化BillingClient
private String TAG = "MainActivity";
private BillingClient billingClient;
private Handler handler = new Handler();
private final int consumeImmediately = 0;
private final int consumeDelay = 1;
billingClient = BillingClient.newBuilder(this).enablePendingPurchases().setListener(new PurchasesUpdatedListener() {
@Override
public void onPurchasesUpdated(BillingResult billingResult, @Nullable List purchases) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && purchases != null) {
for (final Purchase purchase : purchases) {
if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
// Acknowledge purchase and grant the item to the user
Log.i(TAG, "Purchase success");
//确认购买交易，不然三天后会退款给用户
if (!purchase.isAcknowledged()) {
acknowledgePurchase(purchase);
}
//消耗品 开始消耗
handler.postDelayed(new Runnable() {
@Override
public void run() {
consumePuchase(purchase, consumeDelay);
}
}, 2000);
//TODO:发放商品
} else if (purchase.getPurchaseState() == Purchase.PurchaseState.PENDING) {
//需要用户确认
Log.i(TAG, "Purchase pending,need to check");
}
}
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
//用户取消
Log.i(TAG, "Purchase cancel");
} else {
//支付错误
Log.i(TAG, "Pay result error,code=" + billingResult.getResponseCode() + "\nerrorMsg=" + billingResult.getDebugMessage());
}
}
}).build(); 3.连接google服务器，判断google支付是否可用（需要开启VPN）
//连接google服务器
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(BillingResult billingResult) {
Log.i(TAG, "billingResult Code=" + billingResult.getResponseCode());
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
// The BillingClient is ready. You can query purchases here.
Log.i(TAG, "Init success,The BillingClient is ready");
//每次进行重连的时候都应该消耗之前缓存的商品，不然可能会导致用户支付不了
queryAndConsumePurchase();
} else {
Log.i(TAG, "Init failed,The BillingClient is not ready,code=" + billingResult.getResponseCode() + "\nMsg=" + billingResult.getDebugMessage());
}
}
@Override
public void onBillingServiceDisconnected() {
// Try to restart the connection on the next request to
// Google Play by calling the startConnection() method.
Log.i(TAG, "Init failed,Billing Service Disconnected,The BillingClient is not ready");
}
});4.进行支付，需要传入你在google平台申请的对应商品的支付码
//进行支付
private void pay(String payCode){
List skuList = new ArrayList<>();
skuList.add(payCode);
SkuDetailsParams.Builder params = SkuDetailsParams.newBuilder();
params.setSkusList(skuList).setType(BillingClient.SkuType.INAPP);
billingClient.querySkuDetailsAsync(params.build(),
new SkuDetailsResponseListener() {
@Override
public void onSkuDetailsResponse(BillingResult billingResult, List skuDetailsList) {
Log.i(TAG, "querySkuDetailsAsync=getResponseCode==" + billingResult.getResponseCode() + ",skuDetailsList.size=" + skuDetailsList.size());
// Process the result.
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
if (skuDetailsList.size() > 0) {
for (SkuDetails skuDetails : skuDetailsList) {
String sku = skuDetails.getSku();
String price = skuDetails.getPrice();
Log.i(TAG, "Sku=" + sku + ",price=" + price);
BillingFlowParams flowParams = BillingFlowParams.newBuilder()
.setSkuDetails(skuDetails)
.build();
int responseCode = billingClient.launchBillingFlow(mActivity, flowParams).getResponseCode();
if (responseCode == BillingClient.BillingResponseCode.OK) {
Log.i(TAG, "成功启动google支付");
} else {
//BILLING_RESPONSE_RESULT_OK 0 成功
//BILLING_RESPONSE_RESULT_USER_CANCELED 1 用户按上一步或取消对话框
//BILLING_RESPONSE_RESULT_SERVICE_UNAVAILABLE 2 网络连接断开
//BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE 3 所请求的类型不支持 Google Play 结算服务 AIDL 版本
//BILLING_RESPONSE_RESULT_ITEM_UNAVAILABLE 4 请求的商品已不再出售
//BILLING_RESPONSE_RESULT_DEVELOPER_ERROR 5 提供给 API 的参数无效。此错误也可能说明应用未针对 Google Play 结算服务正确签名或设置，或者在其清单中缺少必要的权限。
//BILLING_RESPONSE_RESULT_ERROR 6 API 操作期间出现严重错误
//BILLING_RESPONSE_RESULT_ITEM_ALREADY_OWNED 7 未能购买，因为已经拥有此商品
//BILLING_RESPONSE_RESULT_ITEM_NOT_OWNED 8 未能消费，因为尚未拥有此商品
Log.i(TAG, "LaunchBillingFlow Fail,code=" + responseCode);
}
}
} else {
Log.i(TAG, "skuDetailsList is empty.");
}
} else {
Log.i(TAG, "Get SkuDetails Failed,Msg=" + billingResult.getDebugMessage());
}
}
});
} 5.确认支付，不然用户付的钱三天后又回到用户的账上了，那还玩毛线
//确认订单
private void acknowledgePurchase(Purchase purchase) {
AcknowledgePurchaseParams acknowledgePurchaseParams = AcknowledgePurchaseParams.newBuilder()
.setPurchaseToken(purchase.getPurchaseToken())
.build();
AcknowledgePurchaseResponseListener acknowledgePurchaseResponseListener = new AcknowledgePurchaseResponseListener() {
@Override
public void onAcknowledgePurchaseResponse(BillingResult billingResult) {
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
Log.i(TAG, "Acknowledge purchase success");
} else {
Log.i(TAG, "Acknowledge purchase failed,code=" + billingResult.getResponseCode() + ",\nerrorMsg=" + billingResult.getDebugMessage());
}
}
};
billingClient.acknowledgePurchase(acknowledgePurchaseParams, acknowledgePurchaseResponseListener);
}
6.消耗用户购买的一次性商品，不然用户无法进行二次购买
//消耗商品
private void consumePuchase(final Purchase purchase, final int state) {
ConsumeParams.Builder consumeParams = ConsumeParams.newBuilder();
consumeParams.setPurchaseToken(purchase.getPurchaseToken());
consumeParams.setDeveloperPayload(purchase.getDeveloperPayload());
billingClient.consumeAsync(consumeParams.build(), new ConsumeResponseListener() {
@Override
public void onConsumeResponse(BillingResult billingResult, String purchaseToken) {
Log.i(TAG, "onConsumeResponse, code=" + billingResult.getResponseCode());
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
Log.i(TAG, "onConsumeResponse,code=BillingResponseCode.OK");
if (state == consumeImmediately) {
}
} else {
//如果消耗不成功，那就再消耗一次
Log.i(TAG, "onConsumeResponse=getDebugMessage==" + billingResult.getDebugMessage());
if (state == consumeDelay && billingResult.getDebugMessage().contains("Server error, please try again")) {
handler.postDelayed(new Runnable() {
@Override
public void run() {
queryAndConsumePurchase();
}
}, 5 * 1000);
}
}
}
});
}7.为了保险起见，每次连接google服务器的时候，都查一下历史订单，并把购买成功的商品消耗一遍，避免之前消耗失败的同类商品无法购买，已经消耗过的商品会提示这个商品不属于你，这个不影响的
//查询最近的购买交易，并消耗商品
private void queryAndConsumePurchase() {
//queryPurchases() 方法会使用 Google Play 商店应用的缓存，而不会发起网络请求
billingClient.queryPurchaseHistoryAsync(BillingClient.SkuType.INAPP,
new PurchaseHistoryResponseListener() {
@Override
public void onPurchaseHistoryResponse(BillingResult billingResult,
List purchaseHistoryRecordList) {
{
if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK && purchaseHistoryRecordList != null) {
for (PurchaseHistoryRecord purchaseHistoryRecord : purchaseHistoryRecordList) {
// Process the result.
//确认购买交易，不然三天后会退款给用户
try {
Purchase purchase = new Purchase(purchaseHistoryRecord.getOriginalJson(), purchaseHistoryRecord.getSignature());
if (purchase.getPurchaseState() == Purchase.PurchaseState.PURCHASED) {
//消耗品 开始消耗
consumePuchase(purchase, consumeImmediately);
//确认购买交易
if (!purchase.isAcknowledged()) {
acknowledgePurchase(purchase);
}
//TODO：这里可以添加订单找回功能，防止变态用户付完钱就杀死App的这种
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
}
});
} 至此，google支付已经完成了，下面是完整的Activity中的代码，涉及到UI的只有一个支付按钮，所以我就不另外搞完整的demo了：

注意事项：
1.记得开启VPN，VPN最好是连接美国的
2.手机上需要安装google play service，并且需要在权限设置里面允许弹窗权限
