问题描述
我将 Android Studio 中的 Google Play Billing Library 从 3.0.3（运行良好）迁移到 4.0.0。 我检查了我的 Google Play Billing，一切似乎都正常，SKU 状态为 ACTIVE（没有危险信号）。 我已尽力遵循迁移说明@https://developer.android.com/google/play/billing/integrate#establish_a_connection_to_google_play
到目前为止，我只能确定与 Google Play Billing 的连接正常，也就是说，在 onBillingSetupFinished() 方法之后，BillingClient.BillingResponseCode.OK 响应良好，没有错误消息。
我的问题从调用 querySkuDetailsAsync() 开始：这里没有响应，甚至没有错误通知。谷歌网站非常强调这次通话，所以我觉得这就是乐趣的开始。
我已经提供了问题的示例代码。我已经使用了 Stack Overflow 的许多修复程序，但现在我真的被卡住了，真的需要它来工作。
我的问题代码如下：
'''
/*
//Using the following library in build.graddle for app module
dependencies {
def billing_version = "4.0.0"
implementation "com.android.billingclient:billing:$billing_version"
}
*/
StringBuilder builder4SKUInfo;
private void get_Subscribe2_Characters() {
Subscribe2_Characters_Button.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//I Toggle Visibility of Views Here
billingClient.startConnection(new BillingClientStateListener() {
//Android Studio auto-prompts to generate onBillingSetupFinished & onBillingServicedisconnected
@Override
public void onBillingSetupFinished(@NonNull BillingResult billingResultC) {
if (billingResultC.getResponseCode() == BillingClient.BillingResponseCode.OK) {
//BillingResponseCode is OK here: Works Just Fine!
//The problem starts below
String skuToSell = "MySKU_Character_001"; //In my project,the SKU is cut-pasted from Google Play Console
List<String> skuList = new ArrayList<> ();
skuList.add(skuToSell);
SkuDetailsParams.Builder params = SkuDetailsParams
.newBuilder()
.setSkusList(sku_Details) //
.setType(BillingClient.SkuType.SUBS);
billingClient.querySkuDetailsAsync(params.build(),new SkuDetailsResponseListener() {
@Override
public void onSkuDetailsResponse(@NonNull BillingResult billingResult,@NonNull List<SkuDetails> PurchaseDetailsList) {
//nothing! Not getting BillingResult
//Problem seems to at this point
if (PurchaseDetailsList.size() > 0) {
//nothing! Not getting size
for (SkuDetails PurchaseSKU_Info : PurchaseDetailsList) {
builder4SKUInfo = new StringBuilder(300);
if (PurchaseSKU_Info.getSku().contains("MySKU_Character_001")) {
String getSKUInfo = (
"\nTitle [Query]: " + PurchaseSKU_Info.getTitle()
+ "\n\nDetails: " + PurchaseSKU_Info.getDescription()
+ "\n\nDuration: " + PurchaseSKU_Info.getSubscriptionPeriod()
+ "\n\nPrice" + PurchaseSKU_Info.getPrice()
+ "\n\nAvoid Problems:\nUpdated Subscription Settings on Google Play"
+ "\n\nIMPORTANT: NOT Transferable"
+ "\n\n For this device only\n");
//+ "\nOther SKUs: " + SKU_Info.getSku()
//"001 = " + billingResultB.getResponseCode()
//+ "\nList Size: " + PurchaseDetailsList.size());
builder4SKUInfo.append(getSKUInfo); //The result I need to use elsewhere
}
}
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ITEM_ALREADY_OWNED) {
//No Google Play response for this
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.ITEM_NOT_OWNED) {
//No Google Play response for this
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.USER_CANCELED) {
//Do something about cancels
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.BILLING_UNAVAILABLE) {
//No Google Play response for this
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.SERVICE_disCONNECTED) {
//No Google Play response for this
} else if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.SERVICE_TIMEOUT) {
//No Google Play response for this
} else {
//Following Toast does not show
String SomethingWrong = "Somethings is Wrong" +
"\nUpdate Your Google Play Billing Info" +
"\nCheck Internet Connection";
Toast.makeText(KH.this,SomethingWrong,Toast.LENGTH_LONG).show();
}
}
});
}
}
@Override
public void onBillingServicedisconnected() {
//Following Toast does not show
String BillingServicedisconnected = "Billing Service disconnected" +
"\nUpdate Your Google Play Billing Info" +
"\nCheck Internet Connection";
Toast.makeText(KH.this,BillingServicedisconnected,Toast.LENGTH_LONG).show();

解决方法
所以我勇敢地在问题跟踪页面上询问谷歌的人，他们适当而迅速地回答，“我们现在将结果发布到后台线程而不是 UIThread ......”
马上，我知道我的方法是错误的。如果结果被传递到后台线程，我不得不放弃 3.x 计费方法并从头开始。
我再次联系 Google 获取示例，他们向我发送了他们的 GitHub @ https://github.com/android/play-billing-samples/tree/main/TrivialDriveJava
该示例类似于“意图”，但具有比函数选择更多的代码声明：有几个类、方法和文件需要处理。因此，要修复 billing 4.x，最简单的方法是将示例翻录到我的应用程序中，减少错误，将我不需要的方法灰显，最后覆盖我的视图，重构类（再次修复错误）并创建新的用户工作流程。
,按照@Maasaivatar 的回答，它在主线程上运行 SkuDetailsResponseListener 后工作：
billingClient.querySkuDetailsAsync(params.build(),(billingResult,list) ->
runOnUiThread(() -> {
// same code as before
}));
