android - Motion detection versus conserving battery -


in app, have service running in background, in time ranges user determines.

in theory, need know user's distance destination. optimizations, i'm implementing own proximity alert, sleeps time frames according current distance.

moreover, if user not in motion @ all, stop locations updates, since know it's not moving. used listener acceleration sensor. leaving on long ranges of time draining battery, since minor updates arrive constantly.

i know increase time frames of locationing (i read great article in android developers..), it's highly risky correctness.

did 1 ever face similar problem? suggest different designing?

thanks help

android kitkat adds new sensor type, type_significant_motion, designed solve problem. if supported, causes motion sensor wake system motion events significant enough cause location change.

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!
