ZK Mobile for Android

The ZK Mobile for Android is the ZK extension that enables richness of ZK applications to Android platform mobile devices with little programming. With the event-driven components and a markup language on server side, developing is as simple as programming desktops and authoring HTML. No Android prerequisite is required. The architecture of the ZK Mobile Computing for Android is as follows,

Binding ZK and Android by Server-Centric Architecture

With ZK's server-centric architecture, developing Android application becomes a very easy task. ZK mobile developers only need to write MIL (Mobile Interactive Language) files in ZK tags without understanding Android SDK detailly. MIL is a markup language that enables developers to author a page without programming. Also, due to the tendency of server-centric framework - application runs on server, developers don't need to re-deploy applications when applications update occurs and the business logic is controlled in server side. As soon as the application installed at the server is upgraded, the user will access the most updated version automatically. Moreover, the business logic is running at the server, so it requires much less memory in the mobile device.


ZK with Android in Action

Next, we implement a twitter application to demonstrate how easy developing ZK Android application can be.
