i have found problem. using bs3 rc1. downloaded rc2 , problem fixed. .collapse class hidden on mobile , shown on desktop. reason missing @media rule in bs3 rc1 css (missing @ least devtools when inspecting .collapse element):

@media (min-width: 768px) .navbar-collapse.collapse {     display: block !important;     height: auto !important;     padding-bottom: 0;     overflow: visible !important; }

so works bootstrap 3 rc2.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
