  • Java runtime based on Android ART
  • A new Java to native library with automated native binding generation

Upgrading GWT Checkstyle Setup to support Checkstyle 5

GWT, the Google Web Toolkit is a widely known framework that allows developers to use the Java language to write AJAX Web Applications.

It is a less known fact that the GWT developers have a pretty strict code style in effect. Of course any policy will only work as intended, if it is enforced. GWT uses Checkstyle to enforce the code style rules. The source tree also includes instructions and code formatter specifications for the Eclipse IDE. One nice thing about this code style is that the methods and optionally the fields are ordered alphabetically, which makes the diffs much easier to read.

Unfortunately Checkstyle 5 is not completely backwards compatible with Checkstyle 4, so the GWT rules need to be updated.
Also, the latest Eclipse-CS plugin, no longer supports the old method for adding extension rules, it now requires an Eclipse plugin for this, according to the documentation.

I updated the Checkstyle rules + created a plugin project from the custom checks for the new Eclipse-CS plugin.

Google Android from a Developer's Perspective - Talk at the Free Software Conference 2009, Szeged

I gave a talk at the Free Software Conference 2009: "Google Android from a Developer's Perspective".

After the presentation I held a workshop, where I showed in practice how nice the development environment of Android really is. I used PreziMote, our OpenOffice.org remote control application as an example, which is able to control presentations over Bluetooth.

The slides may be downloaded from here. (in Hungarian)

How to use Google App Engine in Education

I had a talk at the LOK 2009 (Linux in Education) conference about Google App Engine. In the presentation I gave an overview about the App Engine itself:

  • The general architecture.
  • The Python runtime.
  • A very brief introduction into the data store.
  • A demo application to show some of the features.

At the end of the presentation I showed a very basic message wall application. It is online at: http://lok-2009.appspot.com.
