android - ADB doesn't work, device offline, ADBD gives segmentation fault -


i have viewsonic vb100a tablet, , i'm trying use adb app debugging.

when start device, adb works fine. after disconnect, wait while , reconnect, adb gives "device offline" error when trying adb command (devices, shell, none work).

using terminal emulator found out md5 hash of file /sbin/adbd changes. these hashes of files.

working: 06507f51e43a4632507dba159a5cbd13

not working: a2ff86b348e615cce5603cd4761089ef

what cause problem? broken memory chip? don't think since rebooting android restores it.

thanks in advance help!

edit: here's link both binaries md5 sums

edit 2: i've made simple app copies adbd sd card /sbin , restarts it. it's not convenient way, it's better restarting device time :)

i don't know causes changes in adbd, have tried this?

$ adb kill-server

this command kill adbd , if adb shell after restart adbd.

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!
