java - In Android, how to find the total used memory (native and non-native) in bytes for my app programmatically? -


although there similar questions (such a), answers not solve problem.

i using android studio 1.5.1 targeting android api 18 (before android kitkat 4.4, i’m dealing dalvik, not art runtime).

my question is:

in android, how find total used memory (native , non-native) in bytes used app programmatically without using native code?

update:

why other similar solutions not solve problem?

here problem in more details:

i have 2 methods, before() , after(). bothe methods have same code calculate total used memory method after() has integer local variable

int consume = 123;

the problem after() method should show total used memory + 4 (which size of int variable consume), instead of both give me same total used memory.

not sure why other answers didn't solve problem, doing @ same api level.

public static void getmemorystat(){      double max = runtime.getruntime().maxmemory();      double heapsize = runtime.getruntime().totalmemory();      double heapremaining = runtime.getruntime().freememory();      double nativeusage = debug.getnativeheapallocatedsize();       double totalmemoryused = (runtime.getruntime().totalmemory() + android.os.debug.getnativeheapallocatedsize());     int percentused = (int)(totalmemoryused / runtime.getruntime().maxmemory() * 100);     double remaining = max - (heapsize - heapremaining + nativeusage);      errorlog.log("max:"+ max);     errorlog.log("heapsize:"+ heapsize);     errorlog.log("heapremaining:"+ heapremaining);     errorlog.log("nativeusage:"+ nativeusage);     errorlog.log("remaining:"+ remaining);     errorlog.log("percentused:"+ percentused);  }

errorlog custom class. should change log.d()

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

(and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
