Creating demo and full version app based on one code base/project

Question

I have developed one Android app in one project with Eclipse - it\'s structured (coming from iPhone) so one constant defines whether it\'s the demo or the full version.

Answer 1

I see the simplest approach would be to have three projects:

1. demo
2. full
3. library

The demo and full projects will each have their own unique package name as defined in their respective Manifest file. Their Activities are merely ports that send information in a bundle to the primary Activity in the library project. The Activity in the library project will read the Bundle passed in for the necessary parameters that determine whether it was launched by the demo Activity or the full Activity. Then it will proceed accordingly.

So the logic is like this:

User launches the demo Activity -> The demo Activity creates a Bundle with the information that says it's the demo Activity -> The demo Activity launches the library Activity which then executes the rest of the program in demo mode.

OR

User launches the full Activity -> The full Activity creates a Bundle with the information that says it's the full Activity -> The full Activity launches the library Activity which then executes the rest of the program in full mode.
