為什么我在android studio中的代碼中出現錯誤？

Question

我正在做一個定制應用程序，用戶在其中購買個性化產品。 我正在嘗試執行購物籃頁面，但它無法正常工作。 我在Bundle BuyIntent = mservice.getBuyIntent(3, getPackageName(), sku,"Purchase text item","bGoa+V7g/yqD"); 以及在skuDetails= mservice.getSkuDetails(3, getPackageName(),"Purchase text item", querySku); 。 就是說無法解決方法。 請有人幫忙，謝謝。

您可以為getSkuDetails（）添加聲明嗎？ 從錯誤消息中聽起來，您可能期望的是不同數量的參數或不同的數據類型。
