Hi Nuno, Thanks for your reply. >Maybe you need to enable a specific capability. Yes. I did it. I add/enable some Key entries to info.plist like "location update” under the Background Modes"
>Also, have you seen my last email? T Yes i did have. All my call back methods are ok. My problem is they (specially didFinishLaounchWithOptions) do not work when the app is Killed (i mean, when the user tap the home button and forces to kill the app).
