If you don't have a service running, your process is somewhat by definition not continuously running and you can't consider it as such. Even if you do have a service running, you can count on the process occasionally being killed in the background though in that case it will generally get restarted soon after to continue running the service (if there is enough memory to do so). > Also, I never see this problem on my own phone and only one user (out of > appx 180 active widget installations) is complaining.
