PDF file or images for a book in android application -


i developing android book selling application problem don't know if should use books pdf file or images. reading of books inside application.

you should use .pdf extension ebook.
because images tend become pixelerated when zoomed level. pdf preserves vectors , not reduce quality of content (images, text, etc) when zoomed.
along that, pdf wrapped collection of pages in single file. instead of many different image files single ebook.

there many open source libraries rendering pdfs in android
have used mupdf library rendering pdf files in android app.

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!
