managing an array
<p>I want to save some that in an array and then use that . but the problem is that this is a large size data and I'm not sure if it's good idea or even possible to save all of that into an array . probably I should have some mechanism like deleting array items from the top ? </p>

<p>this is an android application and it's in real time so the speed is really important.</p>

<p>please help!</p>
