Best way to do a update every minute
<p>i need to make an update every minute by checking a xml to know if i need to update or not.</p>

<p>I hesitate between some way because i haven't proprely understood service on android</p>

<p>I can do an alarm who launch a activity every minute my activity need to be a reicever or a service?</p>

<p>Can i launch a service every minute without an alarm?</p>

<p>Or need i to make a loop in my service who launch a function every minute?</p>

<p>And can i (if i use alarm and launche many time same activity/service) keep a variable to know if i need to update i mean if i need to dll big file during update it can be longer than 1 minute and i don't wan't to launch multiple update at the same time so i need to use a boolean to know if an update is active or not.</p>
