Android Question How to use JavaObject

[LucaMs]

I know that what I ask is not simple.

I would like someone to describe the use of JavaObject (a little tutorial?), for example in this code

 

[Erel]

The Switch class code is not a good example as it is a complicated one which requires good understanding of B4A internal framework.

 

[LucaMs]

Precisely for this reason I chose that example

I agree with LucaMs, also I would need to understand better and more thoroughly how objects work and invites you to Java Object, so it would be really helpful to have a more thorough and complete tutorial
Thank You
