start activity from service?!

[Mutenroshi]

Hi, trying to start activity from service started at BOOT (android.intent.action.BOOT_COMPLETED), but log shows how application dies (don't know why exactly) and restarts and triees again and again..

If I launch activity from another activity ther is no problem. Maybe reason is trying to launch activity from service started at BOOT (?).

I've tried differents ways of starting activity, like

Intent newUserForm = new Intent(_context, NewUserForm.class);
newUserForm.setFlags(Intent.FLAG_FROM_BACKGROUND | Intent.FLAG_ACTIVITY_NEW_TASK );
_context.startActivity(newUserForm);

Why is my app dying (and restarting) and I'm not able to start activity from service who starts at BOOT??
thank you!!!!!!
