Should I use a app killer or not? I see that they seem to be common and highly rated but I've also read posts on other forums saying that they shouldn't be used and Android should be allowed to manage the apps. Also, I've installed Advanced Task Killer and while it seems to work well, some apps like Moxier Mail open back up with in seconds of being killed. Lastly, last night I used Advanced Task Killer to close all apps, turned the phone off and put it on the charger. This morning I turned on the phone, pulled down the notification bar and saw about 15 programs waiting to be killed. Can anybody give a noob an explanation on how Android handles apps, if I should use a app killer and lastly, explain how apps can open on their own.
