Android Question Add-on like

[luke2012]

I'm planning to add a new functionality (that introduce a new DB and interface) in my app but I wish configure it like an add-on component that can be installed on demand by a subset (only interested users).

Which is the best approach ?

1) By an external app that can be installed within the main app ?
2) By a hidden GUI that can be enabled (for example within Android menu) by user on demand
3) Other ?

Hard to say. It is not possible to "extend" a current Android app with new code. So you should either add it as another app or include the code in the original one.
