what tried far: publish wcf service on iis using file system of visual studio. after publishing when try browsing address 192.168.5.103:12345 on mobile , desktop, looks fine when access using wcf throws status 400 bad request error. don't know main problem. attaching screenshots please have look. use line in gradle compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

tools: visual studio 2012 , android studio
