|
|
<p>Sometimes, the best way to learn how things are done is to look at some
|
|
code.</p>
|
|
|
|
<p>To help you get started quickly, the Android SDK includes a variety of sample
|
|
code and tutorials that illustrate key concepts and techniques of Android
|
|
application development. For example, the samples show the structure of the
|
|
manifest file and the use of activities, services, resources,
|
|
intents, content providers, and permissions. They also show how to add
|
|
specialized capabilities to your apps, such as Bluetooth and Contacts
|
|
integration, multiple screens support, Live Wallpaper, and more. </p>
|
|
|
|
<p>The SDK provides the samples both as source code and as browseable HTML, as
|
|
described in the sections below. All of the samples included in the SDK are
|
|
licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache
|
|
2.0 license</a>, so feel free to use any of the code in your own applications as
|
|
needed!</p>
|

|
<h3 id="downloading">Downloading the Sample Code</h3>
|
|
|
|
<p>The SDK sample code is available to you as a set of downloadable SDK
|
|
components, each of which contains the samples for a specific Android platform
|
|
version. Once you have installed the SDK, you can download one or more samples
|
|
component(s) into your SDK environment using the Android SDK and AVD Manager
|
|
tool, which is pre-installed in the SDK. </p>
|
|
|
|
<p>To download the samples, launch the Android SDK and AVD Manager tool and
|
|
select one of the samples components from the <strong>Available
|
|
Packages</strong> panel, for example "Samples for SDK API 7". Select
|
|
<strong>Install Selected</strong>, verify and accept the download, then select
|
|
<strong>Install Accepted</strong> to download the component into your SDK. If
|
|
you aren't familiar with the Android SDK and AVD Manager and how to launch or
|
|
use it, please read the <a href="{@docRoot}sdk/adding-components.html">Adding
|
|
SDK Components</a> document. </p>
|
|
|
|
<p>When the download is complete, you can find the samples sources on your
|
|
computer in this location:</p>
|
|
|
|
<p style="margin-left:2em">
|
|
<code><em><sdk></em>/samples/android-<<em>level</em>>/</code>
|
|
</p>
|
|
|
|
<p>You can easily create new Android projects with the downloaded samples, modify them
|
|
if you'd like, and then run them on an emulator or device. </p>
|
|
|
|
<p>For example, if you are developing in Eclipse with the ADT Plugin, you can
|
|
create a project for the "API Demos" sample app by starting a new Android
|
|
Project, selecting "Create project from existing source", and then browsing to
|
|
the <code><em><sdk></em>/samples/android-<<em>level</em>>/ApiDemos</code>
|
|
directory (the <code>samples</code> directory for the platform version you are
|
|
using).</p>
|
|
|
|
<p>If you are not working in Eclipse, you can create a project for the API Demos
|
|
sample using the <code>android</code> tool, by executing this command:</p>
|
|
|
|
<pre class="no-pretty-print">
|
|
android update project -s -n API Demos -t <em><target_ID></em> -p <<em>path</em>></em>samples/android-<<em>level</em>>/ApiDemos/
|
|
</pre>
|
|
|
|
<h3 id="browsing">Browsing the Sample Code</h3>
|
|
|
|
<p>For your convenience, the SDK provides browseable source code for the latest
|
|
versions of the samples. You can use your browser to navigate through the
|
|
structure of each sample and look at the source code in each of its files. </p>
|
|
|
|
<p>To browse the samples, go to the <a
|
|
href="{@docRoot}resources/samples/index.html">List of Sample Apps</a> first.
|
|
From there you can read a short summary of each sample application and what
|
|
types of concepts, features, or APIs it includes. Then, use the links provided
|
|
to move through the directories and files of each sample. The browseable source
|
|
is generated from the same source code that is downloadable through the Android
|
|
SDK and AVD Manager, as described above. </p>
|
|
|
|
<p>The browseable samples files are available online, at the Android Developers
|
|
site only and are not included in the downloadable offline documentation.
|
|
Note that, although samples for several platform versions are available for
|
|
download, only the samples for the latest platform version are browseable online.
