android - What exactly happens when finish() is called on a non-top activity -

-

suppose somehow have reference activity not on top of activity stack. can call finish() on activity, , happen in such case?

also, legitimate reason hold on reference non-top activity? saving reference in static field way have access non-top activities against best practice.

finish() on activity, , happen in such case?

i'm sure can. end black screen non-top activity if still visible on screen.

also, legitimate reason hold on reference non-top activity?

i think have consider whether design correct if have keep reference activity in background. lead lot of memory leaks if keep old activity hanging around gc cannot collect.

saving reference in static field way have access non-top activities

you should use class constants.java put in static fields non-top activity , reuse values constants.java.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
