<p>To develop an Android app, you must install at least one Android platform from the SDK Manager
against which you can compile your app. Often, any given version of the Android will be revised
with bug fixes or other changes, as denoted by the revision number. Below, you'll find the
release notes for each version of the platform and the subsequent revisions to the platform
version.</p>

<p>To determine what revision of an Android platform you have installed, refer to the
<strong>Installed Packages</strong> listing in the Android SDK Manager.</p>

<p class="caution"><strong>Important:</strong> To download the new Android
4.2.x system components from the Android SDK Manager, you must first update the
SDK tools to revision 20 or later and restart the Android SDK Manager. If you do not,
the Android 4.2 system components will not be available for download.</p>

the new WXGA800-7in skin. For best performance, make sure to enable <a

  </li>
  <li>
    WXGA (1280x800, medium density, xlarge screen)
  </li>
</ul>

<p>To test your application on an emulator that represents the latest Android device, you can create
an AVD with the new WXGA720 skin (it's an xhdpi, normal screen device). Note that the emulator
currently doesn't support the new on-screen navigation bar for devices without hardware navigation
buttons, so when using this skin, you must use keyboard keys <em>Home</em> for the Home button,
<em>ESC</em> for the Back button, and <em>F2</em> or <em>Page-up</em> for the Menu button.</p>

<p>However, due to performance issues in the emulator when running high-resolution screens such as
the one for the WXGA720 skin, we recommend that you primarily use the traditional WVGA800 skin
(hdpi, normal screen) to test your application.</p>
