Same APK for free and paid versions on Android Market?

Question

Is it possible to list in Google\'s Android Market a single APK for both free and paid versions?

So far, I only found this tip to create a butt

Answer 1

It's possible to use something known as in app products. The min API is 1.6, which should work plenty well. Basically, anyone could download the code, but some unlocking of features could be done if desired to buy new functionality. They also have sample code which shows how it works.

Alternatively, you could use the licensing API, and simply check to see if your app is licensed. This would require a different package name, however, as all apps do.

Answer 2

You can rename the package before compile and release it as two apps.

i.e. com.example.yourproject and com.example.yourprojectpaid

You need to use the Key for both he LVL and the in app billing and its a good amount of effort to set up. If you want the easy way out use the example above, but know your paid app is not really protected from piracy if you don't use the LVL for your paid app or in app purchases if you keep the app free.

Good Luck.
