错误如下:

第137行: setSku无法解析方法

第232行: mBillingClient.consumeAsync(purchaseToken, onConsumeListener);,第一个参数类型错误

第278行: onPurchasesUpdated(BillingClient.BillingResponseCode.OK, result.getPurchasesList());,错误的第一个参数类型

第289行: int responseCode = mBillingClient.isFeatureSupported(BillingClient.FeatureType.SUBSCRIPTIONS);,不兼容的类型

第338行: mBillingClient.startConnection(new BillingClientStateListener() {,无法解析符号
