我正在尝试为我的应用程序实现应用内计费。
我正在关注 google 的 TriviaDrive 示例应用程序中使用的实现以及开发人员网站上的相关文档。
我的代码按预期工作，但是当我尝试“查询可购买商品” https://developer.android.com/training/in-app-billing/list-iab-products.html#QueryDetails，生成的 Inventory 对象包含 0 个对象，即使我已经创建了一个产品。
I have created a Managed Product with the id paid_version using the Google Play Developer Console, as shown in the image below:
该文档指出“要检索产品详细信息，请致电queryInventoryAsync(boolean, List, QueryInventoryFinishedListener)在您的 IabHelper 实例上。”
在我自己的代码中我调用
mHelper.queryInventoryAsync(true, iabItemSkus, mQueryFinishedListener)
where:
mHelper是我的 IabHelper 实例
iabItemSkus是包含值为“paid_version”的单个项目的列表
mQueryFinishedListener是我的听众定义如下。
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
@Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
if (result.isFailure()) {
Log.d(TAG, "Querying Inventory Failed: " + result);
return;
}
Log.d(TAG, "Title: " + inv.getSkuDetails(SKU_PAID).getTitle());
Log.d(TAG, "Description: " + inv.getSkuDetails(SKU_PAID).getDescription());
Log.d(TAG, "Price = " + inv.getSkuDetails(SKU_PAID).getPrice());
}
};
但在调试时我可以看到Inventory对象传回QueryInventoryFinishedListener包含 0 个项目，因此调用类似inv.getSkuDetails(SKU_PAID).getTitle()给出空指针异常。
我不知道我哪里错了。我本来期待着Inventory对象包含我的详细信息paid_version应用内产品。
下面只是我认为与此问题相关的代码和 LogCat 部分（尽量避免给您带来代码过载！），但如果代码其他部分的更多详细信息会有所帮助，请告诉我。
从我的活动来看：
...
private static final String SKU_PAID = "paid_version";
private static final String TAG = "MyActivity";
private IabHelper mHelper;
...
IabHelper.QueryInventoryFinishedListener mQueryFinishedListener = new IabHelper.QueryInventoryFinishedListener() {
@Override
public void onQueryInventoryFinished(IabResult result, Inventory inv) {
if (result.isFailure()) {
Log.d(TAG, "Querying Inventory Failed: " + result);
return;
}
Log.d(TAG, "Title: " + inv.getSkuDetails(SKU_PAID).getTitle()); // <-- Line 266 of MyActivity.java
Log.d(TAG, "Description: " + inv.getSkuDetails(SKU_PAID).getDescription());
Log.d(TAG, "Price = " + inv.getSkuDetails(SKU_PAID).getPrice());
}
};
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
final List<String> iabItemSkus = new ArrayList<String>();
iabItemSkus.add(SKU_PAID);
// In App Billing
String base64EncodedPublicKey = "... My Public Key ...";
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.enableDebugLogging(true);
mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
@Override
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
Log.d(TAG, "Problem setting up In-app Billing: " + result);
}
// Have we been disposed of in the meantime? If so, quit.
if (mHelper == null) return;
// IAB is fully set up. Now, let's get list of available items
Log.d(TAG, "Setup successful. Querying inventory.");
mHelper.queryInventoryAsync(true, iabItemSkus, mQueryFinishedListener);
}
});
...
}

PS：我刚刚更新了代码以突出显示第 266 行。
额外的
我在上传 APK 12 小时后遇到了这个问题，正如您从 LogCat 中看到的那样，它表明"In-app billing version 3 supported"对于我的应用程序。
无论我将应用内产品的状态设置为活动还是非活动，问题仍然存在。
现在 24 小时后，它神奇地决定正常工作。
由此我只能确定这是 Google Play 的问题，而不是我的代码的问题。
我在同一条船上。我等着看会发生什么。
在谷歌文档中http://developer.android.com/training/in-app-billing/test-iab-app.html http://developer.android.com/training/in-app-billing/test-iab-app.html
有一个警告，也许这就是问题所在：
警告：将 APK 上传到 Google Play 后，最多可能需要 2-3 小时才能识别您更新的 APK 版本。如果您在 Google Play 识别您上传的 APK 之前尝试测试您的应用程序，您的应用程序将收到“购买已取消”响应，并显示错误消息“此版本的应用程序未启用应用内结算”。
