Android lifecycle - are my ideas correct? -

-

i have read android life cycle in couple of books , official documentation, still unable thoughts in 1 place , understand completely. developing simple app, in use fragments, makes harder, fragments have separate life cycle applications. ask couple of questions:

my application simple logger of various data, user needs enter data , @ it. understand, cycles onpause, onresume, onstop shouldn't worry about? guess real question android life cycle methods essential every application?

is considered bad practice if (fragment vise) calling methods , managing views in oncreateview?

do know simple , yet guides me understand how manage android life cycle correctly?

onresume , onpause important part of lifecycle, , should worry it. whenever user change app another, o goes notifications, or whatever, calling onpause() when goes app, , onresume() when came back. have understand activity may killed, (if system don't have enough resources), in case oncreate called first, if not, jump oncreate , goes onresume(). onstop no necessary, should free resources in onpause() because after onpause call, don't know if activity killed system.

fragments includes same activity lifecycle callbacks plus own callbacks.
