android - Get days until date based on timezone on phone -


i´ve been trying figure out while can not wrap head around it. i´m working on android app , want display left specific date, , want number of days based on time zone have set on phone.

i have joda time in app , information have example:

2013-05-05 9.00pm time in pst (gmt-8) timezone, have no clue how , have searched both on google , can not clear answer.

edit

i managed solve problem code found here on so

string datestring = airdate + " " + airtime.touppercase();                  simpledateformat sourceformat = new simpledateformat("yyyy-mm-dd k:mma");                 sourceformat.settimezone(timezone.gettimezone("gmt-8"));                  date parsed;                  parsed = sourceformat.parse(datestring);                 timezone tz = timezone.getdefault();                 simpledateformat destformat = new simpledateformat("yyyy-mm-dd");                 destformat.settimezone(tz);                  result = destformat.format(parsed);

however found out times first got isn´t correct , time zone in format gmt-5 +dst. , dont´t know +dst if setting time 20:00 , using gmt-5 in timezone.gettimezone time returned 22:00 "wrong" since live in sweden. appreciate this.

if settle string looks "in 2 days", should able use dateutils.getrelativetimespanstring().

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!
