我需要一种方法来分享我的应用程序，让人们用优惠券code或促销code或结账code免费下载。我想张贴code到电路板，并在一段时间后失效了。我的应用程序使用许可和应用内结算，所以邮寄APK可能并不合适。我看到了关于这个最后的问题是6个月大，所以我不知道是否有一个新的解决方案。

I need a way to share my app to allow people to download it for free with a coupon code or promo code or checkout code. I would like to post the code to a board, and invalidate it after some time. My app uses licensing and in-app billing, so mailing the APK may not be appropriate. The last question I saw regarding this was 6 months old, so I did not know if there was a newer solution available.

推荐答案

有没有一种方法，与当前的功能，在Play商店设置做到这一点。

There is not a way to do this with the current feature set in the Play store.

您可能会产生使用授权服务（http://developer.android.com/guide/market/licensing）也许在应用程序内购买类似的效果。然而可悲的是，你将不得不做最自己的工作。

You could produce a similar effect using the Licensing service (http://developer.android.com/guide/market/licensing) and perhaps in-app purchases. However sadly you will have to do most of the work yourself.
