my concern class cast exception @ end. it's pain getting poi compile in android environment , had use version 3.9 of poi. i'm wondering if bug hasn't been fixed yet.

here's short code segment related it:

               string fpath = data.getdatastring();                 inputstream is2 = getcontentresolver().openinputstream(uri.parse(fpath));                 list<xssfpicturedata> lst = spreadsheetreader.getpicturesxlsx(is2);  public static list<xssfpicturedata> getpicturesxlsx(inputstream is)     {         list<xssfpicturedata> lst = null;         xssfworkbook wb = null;         try {             wb = new xssfworkbook(is);             lst = wb.getallpictures();         } catch (ioexception e) {             e.printstacktrace();         }         return lst;     }

there error trips on 'wb = new xssfworkbook(is);' line, has worked fine excel files have no images. of note, @ point in code, no other application or code segment accessing file. in advance help.

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, ...
