-    <p>The Android SDK has changed! If you've worked with the Android SDK before,

-    <ul style="padding-bottom:.0;">
-    <li style="margin-top:.5em">The SDK downloadable package includes <em>only</em>
-    the latest version of the Android SDK Tools.</li>
-    <li>Once you've installed the SDK, you now use the Android SDK and AVD Manager
-    to download all of the SDK components that you need, such as Android platforms,
-    SDK add-ons, tools, and documentation. </li>
-    <li>The new approach is modular &mdash; you can install only the components you
-    need and update any or all components without affecting other parts of your
-    development environment.</li>
-    <li>In short, once you've installed the new SDK, you will not need to download
-    an SDK package again. Instead, you will use the Android SDK and AVD Manager to
-    keep your development environment up-to-date. </li>
-    </ul>
-    <p style="margin-top:0">If you are currently using the Android 1.6 SDK, you
-    do not need to install the new SDK, because your existing SDK already 
-    includes the Android SDK and AVD Manager tool. To develop against Android 
-    2.0.1, for example, you can just download the Android 2.0.1 platform (and 
-    updated SDK Tools) into your existing SDK. Refer to <a
