Robotium is an open source testing framework for Android applications. It makes it easy to write complex black-box test cases. Test driven development is a methology where tests are written before the actual application.

1. Write a testcase
2. Watch it failing
3. Write the actual source code in you application which enables the test to pass
4. Watch the test passing
5. Go back to step 1

The following video gives you an introduction into Robotium:

I will definitely use Robotium for my future Android projects. It is really worth having a look at it.

How to install (Oracle) Sun Java SDK 1.6.x (Java 6) on Ubuntu

Herbert Mühlburger — Mon, 10 Jan 2011 20:45:32 +0000

Dieser Beitrag beschreibt die Installation des Sun Java SDK 1.6.x on Ubuntu (Maverick). The English explanation on how to install Sun Java SDK 1.6.x can be found here.

Canonical-Partner Repositories aktivieren:

Dies geschieht unter “System” -> “Systemverwaltung” -> “Synaptic Paketverwalung”. In der Paketverwaltung finden sich die Paketquellen unter dem Menüpunkt “Einstellungen”. In den Einstellungen wechselt man auf den Reiter “Andere Software” und aktiviert dort “Canonical-Partner” bzw. “Canonical-Partner (Quelltext)”. Nach dem Klick auf “Schließen” werden die Paketlisten neu geladen.

Terminal öffnen und Java 6 JDK installieren:

$ sudo apt-get install sun-java6-jdk

Java Version zur Standardversion auf dem System machen:

$ sudo update-java-alternatives -s java-6-sun

Für das aktuelle Java Development Kit wird der Symlink /usr/lib/jvm/java-6-sun erstellt. Dieser zeigt auf die aktuell installierte Version des JDK.

Installation überprüfen:

user@ubuntu:~# java -version
java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)

Damit ist die Installation abgeschlossen.

Vielen Dank an Michael Noll für die englische Installationsanleitung, die ich als Vorlage verwendet habe.

JavaFX Links of the Week 1, February 2010

Herbert Mühlburger — Mon, 01 Feb 2010 08:20:00 +0000

Today I decided to post regularly interesting JavaFX links of the past week. Thanks to Jonathan Giles for his great posts on “Java Desktop Links of the Week”. The JavaFX links are just taken from Jonathan’s posts in order to build a little JavaFX news archieve on my own blog and to inform my subscribers on interesting JavaFX news.

Here are the JavaFX Links of the Week 1, February 2010:

Jim Weaver sums up the Oracle news this week nice and succinctly: ‘We will invest heavily in JavaFX‘.

The JavaFX tutorial has been updated to include a gentler introduction to data binding and triggers, with a new chapter devoted exclusively to “the basics”. Also, apparently there are plans to include a more advanced article discussing this topic also.

Want tabs in your JavaFX application? Well, today’s your lucky day as toumaille has posted exactly this. His tabbed pane control appears to be well thought out, and may be of use to people out there, certainly until there is an official tab control in JavaFX.

Drew, carrying on his investigation into JavaFX and physics, has put up a JavaFX applet of a very, very simple platform game using real physics.

Exadel released a new version of their JavaFX Plug-In for Eclipse, taking it up to version 1.2.1.

Jim Weaver introduces an interesting visualisation developed in JavaFX by Nik Silver. You can go directly to the visualisation if you are interested in playing with it.

Simon Morris has put up a page that contains all of the demos he wrote whilst writing his book ‘JavaFX in Action’.

Pedro Duque Vieira has written about how he has embedded a JavaFX scene into a Swing application.

Krishna Kishore has created a JavaFX application that grows/animates flowers onto the screen. It’s a rather nice effect, and shows the power of the language given Krishna admits creating this program just to learn the language.
