[android-beginners] Re: Creating a Lite and Pro version of an application

[Jeffrey Blattman]

what's missing from the market is dependencies. i often had the idea of publishing an "app" that is just a service for use by other apps ... but the fact that the user needs to manually download the service first sort of rules that out. if we had dependencies, you could have an app core and then have a free and paid app "check" that depend on the core. all the checker activity does it set some bit and then launch the core.  yes i know that's a lot of hand waving.

Is there a way where a user could download just the paid app?

Doing it the way I described in the other thread allows the main application to contain all the functionality to run in both "lite" and "paid" modes.  The mode that the application runs in is determined by whether you have the key installed, which of course would have to have a separate package name because you are not allowed to upload two projects with the same package name.  The application that acts as a key never even has to run... it just has to exist. Although, in my case, I have my key program set to just launch my main app and quit. Pulling common stuff out into a separate library would "work" (kind of) but it would not be as easy as my method.

Another approach is to try to pull out as much common functionality as you can into a 3rd Java-only project, with each of your projects (paid and free).  The tough part is that you can't move anything that references resources into a Java-only project.
