[android-developers] Re: Offering free and paid APKs on the Market

Use the in-app billing model. It will save you a lot of headaches.
To solve the issue I raised earlier, you could turn the current paid
app into more of a "License key" package. On first run your freemium
app would check for the presence of the paid apk and ask the Market to
replay your managed transactions. If the paid app is installed or the
Market gives you a purchase receipt, you're in the paid version. Save
this to your sharedpreferences so you only have to do this once (You
might look at Application Data Backup to save it to the cloud too).

This has the added advantage that you can use the existing paid app to
redirect users to the new freemium app. Just make sure that you put
in the Market entry that the package is there for legacy support only
and that new users should just download the freemium apk.
