I have been developing a free game (with ads) on the Android Market. Now quite a few people are requesting me to do a paid version without ads. I have no experience in keeping multiple versions of a single app.
I have already factored out the app on Eclipse: a library project and a (free) app project. Now I'm going to add a new project for the paid version.
My main problem has to do with the most efficient and reliable way to import old settings and data from the free version if it happens to be already installed on user's phone.
ContentProvider.Is there an easy way to query for data and settings from another app of mine, given the package name?
Thank you very much.

You can change your app from paid to free. Once your app has been offered for free, the app can't be changed to paid. If you want to charge for the app, you need to create a new app with a new package name and set a price.
For Android As a first step, go to your Google Playstore. Then, tap on the menu icon. As a result, the menu opens and several choices appear. If Subscriptions is not among your top choice, scroll down and tap on Account and then on Subscriptions.
How Much Does it Cost to Put an App on the Play Store? There is only a one-time fee of $25 which you pay when you publish your first application. After this, all the apps you publish on google app store for android are cost-free.
You don't need to copy anything or even install another app. Just add an in-app purchase to the free app that disables ads.
