Java google play支付流身份验证错误

嗨，我正在尝试测试我的inapp购买。我已经建立了一个商户帐户，并创建了一个alpha测试组。但是，当我尝试在我的设备上的应用程序上启动付款时，我收到以下错误。我已经在两个不同的设备上测试过了，我得到了相同的错误，尽管我可以下载其他应用程序

错误 需要进行身份验证。您需要登录到您的Google帐户

请帮忙

我的源代码来自普通驱动器示例步骤1：检查基本64键

步骤2：检查您的Sku

static final String SKU_GAS = "android.test.purchased";

检查你的BASE64APP Id，但它不可用？嗨，谢谢BASE64APP Id不正确，我已经更正了它，但是我仍然收到错误。你能把错误日志放在这里吗！！？？当我在应用程序内对话框中收到您正在接收的错误时，logcat中没有错误？？
