This is a Quick Tutorial – My goals
Beginners will see a simple but concrete case-study
Acceleo addicts will discover some new killing features
Android experts will learn enough of the basics to be able to create advanced
code generator in a few days. As you will see, I'm not an Android expert...

Acceleo Code Generation
Let's start with an Android example
Prototype based approach – Starting from an example
A classic example of Android application : « MyContacts »
« We would like to be able to fully generate the same kind of application »

Acceleo Code Generation
Let's start with an Android example
The prototype sources and the model
Different kinds of sources to be generated!
Java UI, Java DB, XML, properties...
The model must contain all the specific settings of the application
Android Activity, Entity Fields...
One model element → « N » generated text parts

Acceleo Code Generation
Let's start with an Android example
Initialize the workflow – The main entry point
An MTL file that calls the other ones... (Mentioned in the OMG specification)
Java / MWE / ANT? Call the Java Standalone API to run the code generation!

Acceleo Code Generation
Let's start with an Android example
A little bit about incremental generation
« My web service is conserved when I generate the application again »
→ Defining specific coding zones with user tags [protected]
→ Using JMerge with the @generated annotation

Acceleo Code Generation
Let's start with an Android example
Workbench Acceleo views – Edit and maintain!
The « Result View » to show how the text and the model are synchronized
The « Overrides View » to override an existing template behavior
The « Patterns View » to define your own completion proposal

Conclusion
Now you can make a complete Android code generator (more widgets...)
We plan to have Acceleo graduate along with the Helios release
Version 3.0 – The last stable release out of Eclipse was 2.x
