我在游戏中使用计费客户端，以便让人们在应用程序项目中购买。
根据我的日志，许多用户无法购买该商品，因为购买流程未启动。
日志显示，大多数启动购买流程的用户都会“卡在”queryProductDetailsAsync 方法上，从而导致错误：
int SERVICE_UNAVAILABLE = 2;
整数错误 = 6;
int NETWORK_ERROR = 12;
问题是，我在成功调用 startConnection 后使用 queryProductDetailsAsync - 我不明白为什么会出现网络/连接错误。
根据我的测试，它总是成功的。 我也在朋友的手机上测试了一下，也成功了。 此外，我确实看到一些用户成功购买。 所以我猜这不是配置问题。
所有故障都来自用户设备的日志

如您所见 - 问题出在 queryProductDetailsAsync 方法中。
我错过了什么？
我正在使用： 实现 'com.android.billingclient:billing:7.0.0'
