CodenameOne - GUI values from checkboxes, comboboxes and save captured photo to Cloud

I'm using NetBeans with CodenameOne and the theme GUI builder. I have created a Main Form with checkboxes in a container, and comboboxes in another container. How can I use a GUI value from the checkboxes and the comboboxes in the StateMachine to save in Cloud Storage? I have also captured a photo to the Main Form and want to save all in Cloud Storage.

Thanks in advance.
