GdxPay "onPurchaseHistoryResponse failed with responseCode -1"

Question

以下是我在 AndroidLauncher onCreate 方法中设置采购管理器的方法（使用 libgdx 1.9.6 和 gdxpay 0.11.3）：

purchaseManager = new PurchaseManagerGoogleBilling(this);
PurchaseManagerConfig pmc = new PurchaseManagerConfig();
pmc.addStoreParam(PurchaseManagerConfig.STORE_NAME_ANDROID_GOOGLE, base64EncodedPublicKey);
pmc.addOffer(new Offer().setType(OfferType.ENTITLEMENT).setIdentifier(globals.skuFullVer));

myPurchaseObserver = new MyPurchaseObserver(globals, highScores);
purchaseManager.install(myPurchaseObserver, pmc, true);

purchaseManager.purchaseRestore();

但是，当调用 purchaseRestore() 时，出现以下异常：

我调试PurchaseManagerGoogleBilling.javapurchaseRestore方法时，responseCodereturns-1和purchase对象为null，通过Gdx报如下错误：

onPurchaseHistoryResponse failed with responseCode -1

请注意，我在设置 PurchaseManager 之后在 AndroidLauncher > onCreate 中调用初始化。

有人对这里出了什么问题有任何指示吗？我使用旧的 IabHelper 完成了付款，但我已经切换到 GdxPay，因为它使用较新的 BillingLibrary，应该更稳定。另外，我只针对 Android.
