Googlein-app计费，一声吐司打破一切
Google in-app billing, a toast breaks everything
我什至不知道这个问题应该起什么标题。
所以，我正在开发一个库，以使 Google-Billing 尽可能容易地集成。
一切都是在我将库升级到 Google's Billing v4 之后开始的，它将 Purchase#getSku 替换为 Purchase#getSkus()。
这是迁移到billing v4之前和之后：
之前（v3 库）：
private void processPurchases(List<Purchase> allPurchases, boolean purchasedProductsFetched) {
if (!allPurchases.isEmpty()) {
List<PurchaseInfo> signatureValidPurchases = new ArrayList<>();
//create a list with signature valid purchases
List<Purchase> validPurchases = allPurchases.stream().filter(this::isPurchaseSignatureValid).collect(Collectors.toList());
for (Purchase purchase : validPurchases) {
Optional<SkuInfo> skuInfo = fetchedSkuInfoList.stream().filter(it -> it.getSkuId().equals(purchase.getSku())).findFirst();
if (skuInfo.isPresent()) {
SkuDetails skuDetails = skuInfo.get().getSkuDetails();
PurchaseInfo purchaseInfo = new PurchaseInfo(generateSkuInfo(skuDetails), purchase);
signatureValidPurchases.add(purchaseInfo);
}
}
if (purchasedProductsFetched) {
fetchedPurchasedProducts = true;
billingEventListener.onPurchasedProductsFetched(signatureValidPurchases);
} else {
billingEventListener.onProductsPurchased(signatureValidPurchases);
}
purchasedProductsList.addAll(signatureValidPurchases);
for (PurchaseInfo purchaseInfo : signatureValidPurchases) {
consume(purchaseInfo);
if (shouldAutoAcknowledge) {
boolean wasConsumedBefore = purchaseInfo.getSkuProductType() == SkuProductType.CONSUMABLE;
if (!wasConsumedBefore) {
acknowledgePurchase(purchaseInfo);
}
}
}
}
}
之后（v4 库）：
private void processPurchases(List<Purchase> allPurchases, boolean purchasedProductsFetched) {
if (!allPurchases.isEmpty()) {
List<PurchaseInfo> signatureValidPurchases = new ArrayList<>();
//create a list with signature valid purchases
List<Purchase> validPurchases = allPurchases.stream().filter(this::isPurchaseSignatureValid).collect(Collectors.toList());
for (Purchase purchase : validPurchases) {
//query all SKUs as a list
List<String> purchasesSkus = purchase.getSkus();
//loop through all SKUs and progress for each SKU individually
for (int i = 0; i < purchasesSkus.size(); i++) {
String purchasesSku = purchasesSkus.get(i);
Optional<SkuInfo> skuInfo = fetchedSkuInfoList.stream().filter(it -> it.getSkuId().equals(purchasesSku)).findFirst();
if (skuInfo.isPresent()) {
SkuDetails skuDetails = skuInfo.get().getSkuDetails();
PurchaseInfo purchaseInfo = new PurchaseInfo(generateSkuInfo(skuDetails), purchase);
signatureValidPurchases.add(purchaseInfo);
}
}
}
if (purchasedProductsFetched) {
fetchedPurchasedProducts = true;
billingEventListener.onPurchasedProductsFetched(signatureValidPurchases);
} else {
billingEventListener.onProductsPurchased(signatureValidPurchases);
}
purchasedProductsList.addAll(signatureValidPurchases);
for (PurchaseInfo purchaseInfo : signatureValidPurchases) {
consume(purchaseInfo);
if (shouldAutoAcknowledge) {
boolean wasConsumedBefore = purchaseInfo.getSkuProductType() == SkuProductType.CONSUMABLE;
if (!wasConsumedBefore) {
acknowledgePurchase(purchaseInfo);
}
}
}
}
}
注意 getSku() 和 getSkus() 的变化。
到目前为止一切顺利。继续解决问题...
在我的图书馆中，我有一个名为 onProductsFetched 的 listener，它将提供一个 List<SkuInfo> 和获取的 SKU 详细信息。
示例：
billingConnector.setBillingEventListener(new BillingEventListener() {
@Override
public void onProductsFetched(@NonNull List<SkuInfo> skuDetailsList) {
String sku;
for (SkuInfo skuInfo : skuDetailsList) {
sku = skuInfo.getSkuId();
if (sku.equalsIgnoreCase(getString(R.string.billing_test_purchase))) {
Log.d("IapConnector", "SKU FOUND: " + sku);
Toast.makeText(SettingsActivity.this, "Fetched: " + sku, Toast.LENGTH_SHORT).show();
}
}
}
});
问题说明：
当使用上面 Before (v3 library) 中提供的代码时，一切都按预期工作，触发侦听器并显示 toast。切换到 After (v4 library) toast 后，一切都崩溃了。日志已在 logcat 中注册，但 toast 未显示。更重要的是，如果我在 toast 之后调用另一个日志，它也不会被注册，实际上在 toast 之后什么都不会被调用，甚至 finish()。但是等等，还有更多，如果我根本不祝酒，一切都会很好。如果我将 toast 替换为 snackbar，则会显示小吃栏。
什么会导致这个问题？有什么想法吗？
更新：
如果我延迟调用 Toast，一切都会按预期进行。
final Handler handler = new Handler(Looper.getMainLooper());
String finalSku = sku;
handler.postDelayed(new Runnable() {
@Override
public void run() {
Toast.makeText(SettingsActivity.this, "Fetched: " + finalSku, Toast.LENGTH_SHORT).show();
}
}, 100);
更新2：
Logcat。注意 D/IapConnector: SKU FOUND: test_purchase7 被调用，它是 Toast

在 V4.0 中，BillingClient 方法回调在后台线程中调用，而不是在主线程中调用。
解决方法是在 BillingClient 回调中将线程更改为 Main。
在 UI 线程中用 Toast 调用方法 processPurchases()。
@researcher answer 是一个完全有效的选项，但对我来说，解决这个问题的最佳方法是触发 main UI thread 上的 listeners，而不是更改所有 [=] 的线程14=] 回调。
他的回答将继续被接受，因为他发现了问题。
为了在 UI 线程上调用 listeners 我创建了一个方法：
private Handler findUiHandler() {
return new Handler(Looper.getMainLooper());
}
然后像这样调用监听器：
findUiHandler().post(() -> billingEventListener.onProductsFetched(fetchedSkuInfo));
我什至不知道这个问题应该起什么标题。
所以，我正在开发一个库，以使 Google-Billing 尽可能容易地集成。
一切都是在我将库升级到 Google's Billing v4 之后开始的，它将 Purchase#getSku 替换为 Purchase#getSkus()。
这是迁移到billing v4之前和之后：
之前（v3 库）：
private void processPurchases(List<Purchase> allPurchases, boolean purchasedProductsFetched) {
if (!allPurchases.isEmpty()) {
List<PurchaseInfo> signatureValidPurchases = new ArrayList<>();
//create a list with signature valid purchases
List<Purchase> validPurchases = allPurchases.stream().filter(this::isPurchaseSignatureValid).collect(Collectors.toList());
for (Purchase purchase : validPurchases) {
Optional<SkuInfo> skuInfo = fetchedSkuInfoList.stream().filter(it -> it.getSkuId().equals(purchase.getSku())).findFirst();
if (skuInfo.isPresent()) {
SkuDetails skuDetails = skuInfo.get().getSkuDetails();
PurchaseInfo purchaseInfo = new PurchaseInfo(generateSkuInfo(skuDetails), purchase);
signatureValidPurchases.add(purchaseInfo);
}
}
if (purchasedProductsFetched) {
fetchedPurchasedProducts = true;
billingEventListener.onPurchasedProductsFetched(signatureValidPurchases);
} else {
billingEventListener.onProductsPurchased(signatureValidPurchases);
}
purchasedProductsList.addAll(signatureValidPurchases);
for (PurchaseInfo purchaseInfo : signatureValidPurchases) {
consume(purchaseInfo);
if (shouldAutoAcknowledge) {
boolean wasConsumedBefore = purchaseInfo.getSkuProductType() == SkuProductType.CONSUMABLE;
if (!wasConsumedBefore) {
acknowledgePurchase(purchaseInfo);
}
}
}
}
}
之后（v4 库）：
private void processPurchases(List<Purchase> allPurchases, boolean purchasedProductsFetched) {
if (!allPurchases.isEmpty()) {
List<PurchaseInfo> signatureValidPurchases = new ArrayList<>();
//create a list with signature valid purchases
List<Purchase> validPurchases = allPurchases.stream().filter(this::isPurchaseSignatureValid).collect(Collectors.toList());
for (Purchase purchase : validPurchases) {
//query all SKUs as a list
List<String> purchasesSkus = purchase.getSkus();
//loop through all SKUs and progress for each SKU individually
for (int i = 0; i < purchasesSkus.size(); i++) {
String purchasesSku = purchasesSkus.get(i);
Optional<SkuInfo> skuInfo = fetchedSkuInfoList.stream().filter(it -> it.getSkuId().equals(purchasesSku)).findFirst();
if (skuInfo.isPresent()) {
SkuDetails skuDetails = skuInfo.get().getSkuDetails();
PurchaseInfo purchaseInfo = new PurchaseInfo(generateSkuInfo(skuDetails), purchase);
signatureValidPurchases.add(purchaseInfo);
}
}
}
if (purchasedProductsFetched) {
fetchedPurchasedProducts = true;
billingEventListener.onPurchasedProductsFetched(signatureValidPurchases);
} else {
billingEventListener.onProductsPurchased(signatureValidPurchases);
}
purchasedProductsList.addAll(signatureValidPurchases);
for (PurchaseInfo purchaseInfo : signatureValidPurchases) {
consume(purchaseInfo);
if (shouldAutoAcknowledge) {
boolean wasConsumedBefore = purchaseInfo.getSkuProductType() == SkuProductType.CONSUMABLE;
if (!wasConsumedBefore) {
acknowledgePurchase(purchaseInfo);
}
}
}
}
}
注意 getSku() 和 getSkus() 的变化。
到目前为止一切顺利。继续解决问题...
在我的图书馆中，我有一个名为 onProductsFetched 的 listener，它将提供一个 List<SkuInfo> 和获取的 SKU 详细信息。
示例：
billingConnector.setBillingEventListener(new BillingEventListener() {
@Override
public void onProductsFetched(@NonNull List<SkuInfo> skuDetailsList) {
String sku;
for (SkuInfo skuInfo : skuDetailsList) {
sku = skuInfo.getSkuId();
if (sku.equalsIgnoreCase(getString(R.string.billing_test_purchase))) {
Log.d("IapConnector", "SKU FOUND: " + sku);
Toast.makeText(SettingsActivity.this, "Fetched: " + sku, Toast.LENGTH_SHORT).show();
}
}
}
});
问题说明：
当使用上面 Before (v3 library) 中提供的代码时，一切都按预期工作，触发侦听器并显示 toast。切换到 After (v4 library) toast 后，一切都崩溃了。日志已在 logcat 中注册，但 toast 未显示。更重要的是，如果我在 toast 之后调用另一个日志，它也不会被注册，实际上在 toast 之后什么都不会被调用，甚至 finish()。但是等等，还有更多，如果我根本不祝酒，一切都会很好。如果我将 toast 替换为 snackbar，则会显示小吃栏。
什么会导致这个问题？有什么想法吗？
更新：
如果我延迟调用 Toast，一切都会按预期进行。
final Handler handler = new Handler(Looper.getMainLooper());
String finalSku = sku;
handler.postDelayed(new Runnable() {
@Override
public void run() {
Toast.makeText(SettingsActivity.this, "Fetched: " + finalSku, Toast.LENGTH_SHORT).show();
}
}, 100);
更新2：
Logcat。注意 D/IapConnector: SKU FOUND: test_purchase7 被调用，它是 Toast

在 V4.0 中，BillingClient 方法回调在后台线程中调用，而不是在主线程中调用。
解决方法是在 BillingClient 回调中将线程更改为 Main。
在 UI 线程中用 Toast 调用方法 processPurchases()。
@researcher answer 是一个完全有效的选项，但对我来说，解决这个问题的最佳方法是触发 main UI thread 上的 listeners，而不是更改所有 [=] 的线程14=] 回调。
他的回答将继续被接受，因为他发现了问题。
为了在 UI 线程上调用 listeners 我创建了一个方法：
private Handler findUiHandler() {
return new Handler(Looper.getMainLooper());
}
然后像这样调用监听器：
findUiHandler().post(() -> billingEventListener.onProductsFetched(fetchedSkuInfo));
