(Great! An answer from the prestigious M.Murphy!! Great books!!) Thanks Mark for your answer..
But the Services in "bound" mode are still not clear for me.. Android Doc says: "If there are clients bound to the service, then the service's hosting process is never less important than the most important client. That is, if one of its clients is visible to the user, then the service itself is considered to be visible. " So if my most important client gets stopped and goes in the background (or even worse, is destroyed), the Service process is then ranked in the same way?? wich means most likely to be also destroyed.. That is my real concern.. Mark, do you confirm my understanding?
