sure! the google i/o 2008 conference marked a significant milestone in the development of android, as it was one of the first major events where developers were introduced to building applications for the android platform. in this tutorial, we'll cover the basics of building a simple android application using the tools and concepts introduced at that time.

overview of android development

at google i/o 2008, the android platform was introduced with a focus on:

1. **java as the primary programming language**.
2. **android sdk**: the software development kit for building android applications.
3. **activity**: the building block of android applications that represents a single screen with a user interface.
4. **manifest**: the androidmanifest.xml file that contains important information about the app, such as its components and permissions.

1. **download the android sdk**: at the time, the android sdk was available for download from the official android website. nowadays, you would typically use android studio, which includes the sdk.

2. **install eclipse with adt plugin**: the android development tools (adt) plugin for eclipse was the recommended ide for android development at that time. however, today, android studio is the preferred ide.

3. **create a new project**: use the ide to create a new android project. you would typically do this through a wizard that guides you through the setup.
