In the last months, I have been looking for an opportunity to get into the Android world.

Finally, after a while I got the right one: porting an iPhone app to Android platform. 

The application is quite simple because it doesn't involve anything far from a common web application: it just retrieves information about events from a web service.

If you make a list of performed tasks, it would look like this:

• retrieving the xml content
• parsing the xml
• storing a few configuration files
• loading images
• building a couple of data structures
• showing everything using the specific views and widgets

Thanks to the reference documents and materials found in the Internet, I got a demo app smiling on my device in a couple of days (not a proper relase, but it could run smoothly).

If you are familiar with Eclipse, you will appreciate the effort made by Google, in order to provide a confortable developement environment. Let's see why.

From the official site you can download:

• Android SDK (JDK required)
• Android Development Tools (ADT) Plugin

You just need to set your SDK. And that's all! Ready to start. 

As you can easily guess, the default API provided by Google is Java-based. 

I know that some of you can argue "Java is not the best choice", but it's solid and well known by most programmers. It is also well documented and it comes with tons of libraries.

The Android application layout is done by a bunch of xml files. The ADT provides a nice interface to manage them.

All the Java code needed for your app can be taken from your personal toolset or grabbed from the net.

What I love most, is that you can easily connect your device and directly deploy the application on it. Moreover, for those who make use of remote debugging in Java, Android (DDMS) is faster and simpler then ever: just press the debug button and your code will be ready for debugging from your android device. Nothing new to the world, but as I said easier then I thought. 

A small disadvantage if you use the virtual device (AVD), because it is really slow, especially in loading.

Just a small consideration: because the hardware behind a mobile device is usually less powerful then a standard pc, you have to be careful.

In a few days the release of AppEventi for Android will be ready. http://www.ferraraterraeacqua.it/
