I puphished a free version of my application and i'm going to publish a paid version with more functions. This paid version is licensing and i want offer few of them. How can i proceed?
您有几种选择在这里：
如果你想充电的正在的为您的免费的应用程序，你什么都不做比修改您的应用程序来处理的应用内就大功告成了购买。
If you wish to charge ongoing license fees for your free app, you do nothing more than modify your app to handle In-App Purchases and you're done.
现在，如果你想的充的这个相同的应用程序（以及可能的许可），你将不得不发布的新的的应用程序到Android Market，设置价格等同样适用在这里如果你希望做应用内购买。
Now if you wish to charge for this same app (as well as maybe licensing), you will have to publish a new app to the Android Market, set your price etc. Same thing applies here if you wish to do In-App purchases.
如果这不是已经很明显，任何和所有购买的 的内部应用程序必须使用应用内计费（Android Market的规则）。
If it wasn't already obvious, any and all purchases within your application have to use In-App Billing (Android Market rules).
