Android client - OpenKM 5.1

Although Android platform programming language is Java, it has some limitations respect the Oracle JDK. For example, the WeServices stuff. So, we need to use an external library to make SOAP request. This library is called ksoap and can be located at http://code.google.com/p/ksoap2-android/.
