在 Google Play 上从免费应用更改为付费应用 [英] Changing from free app to paid app on Google Play

问题描述

这个问题可能跑题了，但我想问问其他开发者.

This question might be off topic, but I wanted to ask the fellow developers.

Google play 上有没有一种方法可以将我的免费应用更改为付费应用?

Is there a way on Google play I could change my free app to a paid app?

如果允许，现有用户会怎样?当新的更新可用时，他们会被要求付款吗?

What would happen to the existing users if it is allowed? Would they be asked to pay when the new update is available?

推荐答案

您可以将应用内支付处理添加到您的免费​​应用中，并为增强功能收费.每

You could add in-app payment processing to your free app and charge for enhanced features. Per

通过使用应用内计费功能，您可以为您的应用添加创收功能，增强付费应用的收入潜力，并将免费应用变成新的收入来源."

"By using the in-app billing feature you can add revenue-generating features to your applications, enhancing the revenue potential of paid applications and turning free applications into new revenue sources."

现在，您能否禁用免费应用中已经提供的功能，然后通过应用内付款进行收费以恢复该功能?从技术上讲，我确实认为这是可以做到的，因为您可以控制这些功能的实现，尽管您必须调查这是否违反了 Google 的政策.

Now, could you disable functionality that was already available in the free app, and then charge via in-app payments to have it restored? Technically I do think it could be done, since you are in control of your implementation of those features, although you would have to investigate whether that would be a violation of Google's policies.

但是，这样做可能会疏远您的用户，如果消息传开，他们甚至可能会停止更新您的应用程序以避免陷入陷阱".所以更好的方法可能是添加诱人的新功能来增强现有功能，然后为it收费.

However, doing it might alienate your users, and if word got around they might even stop updating your app to avoid the "trap." So a much better approach would probably be to add enticing new functionality that enhances the existing functionality, and then charge for it.
