You can follow along +with the steps in each exercise and gradually build up and refine your +application. The exercises explain each step in detail and provide all the +sample code you need to complete the application. </p> + +<p>When you are finished with the tutorial, you will have created a functioning +Android application and learned in depth about many of the most important +concepts in Android development. If you want to add more complex features to +your application, you can examine the code in an alternative implementation +of a notepad application, in the +<a href="{@docRoot}samples/NotePad/index.html">Sample Code</a> documentation. </p> + + +<a name="who"></a> +<h2>Who Should Use this Tutorial</h2> + +<p>This tutorial is designed for experienced developers, especially those with +knowledge of the Java programming language. If you haven't written Java +applications before, you can still use the tutorial, but you might need to work +at a slower pace. </p> + +<p>The tutorial assumes that you have some familiarity with the basic Android +application concepts and terminology. If you aren't yet familiar with those, you +should read <a href="{@docRoot}intro/anatomy.html">Overview of an Android +Application</a> before continuing. </p> + +<p>Also note that this tutorial uses +the Eclipse development environment, with the Android plugin installed. If you +are not using Eclipse, you can follow the exercises and build the application, +but you will need to determine how to accomplish the Eclipse-specific +steps in your environment. </p> + +<a name="preparing"></a> +<h2>Preparing for the Exercises</h2> + +<p>This tutorial builds on the information provided in the <a +href="{@docRoot}intro/installing.html">Installing the SDK</a> and <a +href="{@docRoot}intro/hello-android.html">Hello Android</a> +documents, which explain in detail how to set up your development environment +for building Android applications. Before you start this tutorial, you should +read both these documents, have the SDK installed, and your work environment set up.</p> + +<p>To prepare for this lesson:</p> + +<ol> + <li>Download the <a href="codelab/NotepadCodeLab.zip">project + exercises archive (.zip)</a></li> + <li>Unpack the archive file to a suitable location on your machine</li> + <li>Open the <code>NotepadCodeLab</code> folder</li> +</ol> + +<p>Inside the <code>NotepadCodeLab</code> folder, you should see six project +files: <code>Notepadv1</code>, + <code>Notepadv2</code>, <code>Notepadv3</code>, + <code>Notepadv1Solution</code>, <code>Notepadv2Solution</code> + and <code>Notepadv3Solution</code>. The <code>Notepadv#</code> projects are +the starting points for each of the exercises, while the +<code>Notepadv#Solution</code> projects are the exercise + solutions. If you are having trouble with a particular exercise, you + can compare your current work against the exercise solution.</p> + +<a name="exercises"></a> +<h2> Exercises</h2> + + <p>The table below lists the tutorial exercises and describes the development +areas that each covers. Each exercise assumes that you have completed any +previous exercises.</p> + + <table border="0" style="padding:4px;spacing:2px;" summary="This +table lists the +tutorial examples and describes what each covers. "> + <tr> + <th width="120"><a href="{@docRoot}intro/tutorial-ex1.html">Exercise +1</a></th> + <td>Start here. Construct a simple notes list that lets the user add new notes but not +edit them. Demonstrates the basics of <code>ListActivity</code> and creating +and handling + menu options. Uses a SQLite database to store the notes.</td> + </tr> + <tr> + <th><a href="{@docRoot}intro/tutorial-ex2.html">Exercise 2</a></th> + <td>Add a second Activity to the +application. Demonstrates constructing a +new Activity, adding it to the Android manifest, passing data between the +activities, and using more advanced screen layout. Also shows how to +invoke another Activity to return a result, using +<code>startActivityForResult()</code>.</td> + </tr> + <tr> + <th><a href="{@docRoot}intro/tutorial-ex3.html">Exercise 3</a></th> + <td>Add handling of life-cycle events to +the application, to let it +maintain application state across the life cycle. </td> + </tr> + <tr> + <th><a href="{@docRoot}intro/tutorial-extra-credit.html">Extra +Credit</a></th> + <td>Demonstrates how to use the Eclipse +debugger and how you can use it to +view life-cycle events as they are generated.

You can find the sample +applications in the <code>samples/</code> directory of your downloaded SDK.</li> +<li>This tutorial draws from the full Notepad application included in the +<code>samples/</code> directory of the SDK, though it does not match it exactly. +When you are done with the tutorial, +it is highly recommended that you take a closer look at this version of the Notepad +application, +as it demonstrates a variety of interesting additions for your application, +such as:</li> + <ul> + <li>Setting up a custom striped list for the list of notes.</li> + <li>Creating a custom text edit view that overrides the <code>draw()</code> +method to + make it look like a lined notepad.</li> + <li>Implementing a full <code>ContentProvider</code> for notes.</li> + <li>Reverting and discarding edits instead of just automatically saving +them.</li> +</ul> +</ul> |
