Android Application : Change MBO

Hi all,

I did an android application using a mbo.

That mbo use a bapi which need a default value for one input attribut (must that default for work).

But, when i use that mbo in my application, i don't want all time it use the same default value.

I tried to change that default value and deploy mbo again, and it's good.
But, How change this value IN android application?

Thank for help,
