Presentation and demo app from my talk about Android

I had a talk on local Java User Group a week ago. I was talking about Android. Here I'm providing the presentation and demo application. 

Presentation mainly contains materials from developer.android.com.

Demo application is a twitter client. It shows:

• how the project is layed out;
• what contains the manifest file;
• how activity is build;
• how layouting is done (including reusable layouts with <include> tag);
• how locales are handled (contains Spanish translation);
• how orientation is handled;
• how background threads are handled.

Presentation: Android.odt (yes, that's OpenOffice format).

Demo application: Twitoid.7z (IntelliJ IDEA project, free Community Edition is perfectly fine to check this code).

Twitter4j is used for communication with twitter. Icons are taken from medialoot.com.
