IabHelper：检查订阅是否自动续订

Question

我有一个带有订阅的 Android 应用程序，我使用 IabHelper 查询用户是否有有效订阅。现在我还需要知道这个订阅是否自动续订。

我是这样查询订阅状态的：

private boolean userIsSubscribed() {
    ArrayList<String> skuList = new ArrayList<>();
    skuList.add(PREMIUM_SUBSCRIPTION);
    // Check the subscription status
    try {
        Inventory inventory = iabHelper.queryInventory(true, null, skuList);
        Purchase purchase = inventory.getPurchase(PREMIUM_SUBSCRIPTION);
        // Is the user subscribed?
        if (purchase != null && purchase.getPurchaseState() == 0) {
            // User is subscribed
            Log.d(TAG, "Subscribed.");
            // TODO check if subscription is auto-renewing
            return true;
        } else {
            // User is not subscribed
            Log.d(TAG, "Not subscribed.");
            return false;
        }
    } catch (IabException | NullPointerException e) {
        // There was an error with the subscription process
        Log.e(TAG, e.getMessage(), e);
        return false;
    } catch (IllegalStateException e) {
        // IabHelper not set up
        Log.e(TAG, e.getMessage(), e);
        return false;
    }
}

不幸的是，Purchase 对象没有请求自动更新字段的方法。我还有其他方法可以获得这些信息吗？

调用Purchase#isAutoRenewing方法。如果缺少此方法，您可能需要更新参考 IAB 文件：

    if (purchase != null && purchase.getPurchaseState() == 0) {
        // User is subscribed
        Log.d(TAG, "Subscribed.");
        if (purchase.isAutoRenewing()){
            return true;
        }
