** Service (starter) Create **
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (gm) Create, isFirst = true **
** Activity (gm) Resume **

Move the Person type declaration to the Main module and it will work.

Are you communicating with another B4A app?
