Question regarding to android application

Sorry, I have a stupid question…

if I want to build a android application using JME.

which one is right procedure?

  1. I need to complete the whole java application first, then I use android deployment of JME to convert my java application to the "android version.
  2. I build basic game application of JME without any development and convert it to android application, then develop it from the very first?
