Computersmith64 Well-Known Member Licensed User Longtime User Jan 7, 2020 #2 How about you post the relevant code in Starter. Actually, post the entire Starter service code. It looks like somewhere in there you're trying to reference an uninitialized object. - Colin. Upvote 0

M mw71 Well-Known Member Licensed User Longtime User Jan 8, 2020 #3 Hi, the error happens with the IsPaused line (means the Error Log). That's what i don't understand. I am not sure that the Starter Service is called and the Code is relevant. Upvote 0

M mw71 Well-Known Member Licensed User Longtime User Jan 8, 2020 #8 Hi, i use B4A 9.5 @Erel The user start the App (and StarterService start....), use the app and make Settings (e.g. Backup at.....). Then the User Close the App, e.g. via Code: ExitApplication Activity.Finish -> the StarterService will be close?? At the setting Time (via StartServiceAt) the BackupService is starting and check if Starter is running or not. (because the backup service can also be called from the activity if the user wants an immediate backup) Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Jan 9, 2020 #9 Never call ExitApplication. It will kill the process. If you are not explicitly stopping the starter service, which is a mistake, then it will never be paused. It will stop when the process ends. Upvote 0
