There's no easy way to do that that get's around uninstalling and reinstalling the app. 没有简单的方法可以解决卸载和重新安装该应用程序的问题。 You can do it by autogenerating some sort of login and using a unique device ID and communicating it to a server you own. 您可以通过自动生成某种登录名并使用唯一的设备ID并将其传达给您拥有的服务器来实现。

The licensing service is only available on paid apps. 许可服务仅在付费应用程序上可用。 That means that there is no way to use the licensing service with your free trial app. 这意味着您无法在免费试用版应用中使用许可服务。

If you want to avoid a user reinstalling the app and using it for 30 days again Mike is right. 如果您想避免用户重新安装该应用程序并使用30天，则Mike是正确的。 Get the device ID or IMEI of the handset, for privacy reasons please generate a hash from the id and store the hash on your own server component. 获取手机的设备ID或IMEI，出于隐私保护的原因，请根据ID生成哈希并将哈希存储在您自己的服务器组件中。 Now every time an app starts the hash is sent to the server and the server replies how many days the user used your app. 现在，每次应用启动时，哈希都会发送到服务器，服务器会回复用户使用您的应用的天数。
