HttpClient was deprecated in API Level 22 and removed in API Level 23.
You can still use it in API Level 23 and onwards if you must, 
however it is best to move to supported methods to handle HTTP. 
So, if you're compiling with 23, add this in your build.gradle:

    android {
        useLibrary 'org.apache.http.legacy'
    }

systemProp.http.proxyPort=port
systemProp.http.proxyUser=userid
systemProp.http.proxyPassword=password
systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost
# https
systemProp.https.proxyHost=www.somehost.org

builder.setSmallIcon(R.drawable.ic_launcher);
