Activities

This chapter explains how to declare and launch activities within an application, and how

to manage several activities at once by sharing data between them, requesting results from

them, and by calling one activity from within another.

This chapter also briey explores the Intent object, which is often used in conjunction with

activities (as well as other fundamental components) and is very handy for starting an activity

from any point.

Before following the recipes in this book you will need to install the Android

SDK, the Android AVD manager, and the Eclipse IDE, along with the ADT

plugin. The ADT plugin, which stands for

Android Development Tools,

provides a seamless way to add Android-specic controls to the Eclipse IDE.

Instructions on how to do this can be found at http://developer.

android.com/sdk/installing.html.

Declaring an activity

Activities and other application components, such as services, are declared in the

AndroidManifest XML le. Declaring an activity is how we tell Android about how the activity

can be requested, and what code to run when it is requested. For example, an application will

usually indicate that at least one activity should be visible as a desktop icon and serve as the

main entry point to the application.

Getting ready

As with most recipes, we will be using the Eclipse IDE. If you have not done so already, start

up Eclipse and ensure that you have installed the ADT Plugin.

Android projects are built against a target platform or API level. Here we have used API level

8, which corresponds to the Android 2.2 platform (FroYo). It is quite possible to use any level

for this task but if you intend to make use of the 'holographic' UI you will need to look at the

recipe about optimizing for 3.0 in Chapter 2, Layouts.

How to do it...

The Eclipse Android project wizard is as good a place to start building an application as any

and it will automatically generate a manifest le that includes a basic activity declaration:

1. Run the project wizard. From the Eclipse File menu select New and then

Android Project.
