<h3 id="QuickSearchBox">Quick Search Box for Android</h3>

<p>Android 1.6  includes a redesigned search framework that provides a quick, 

effective, and consistent way for users to search across multiple sources—such as 

browser bookmarks & history, contacts, and the web—directly from 

the home screen.</p>

<p>The system constantly learns which search results are more relevant based on what is 

clicked. So popular contacts or apps that have previously been picked will bubble up to 

the top when a user types the first few letters of a relevant query.</p>

<p>The search framework also provides developers a way to easily expose relevant 

content from their applications in Quick Search Box.</p>

<h3 id="Camera">Camera, Camcorder, and Gallery</h3>

<p>An updated user interface provides an integrated camera, camcorder, and gallery experience. 

Users can quickly toggle between still and video capture modes. Additionally, the gallery 

enables users to select multiple photos for deletion.</p>

<p>Android 1.6 also provides a much faster camera experience.

Compared to the previous release, launching the camera is now 39% faster, 

and there is a 28% improvement in the time from completing one shot to the next.</p>

<h3 id="VPN">VPN, 802.1x</h3>

<p>A new Virtual Private Network (VPN) control panel in Settings allows users 

to configure and connect to the following types of VPNs:</p>

<ul>

  <li>L2TP/IPSEC pre-shared key based VPN</li>

  <li>L2TP/IPsec certificate based VPN</li>

  <li>L2TP only VPN</li>

  <li>PPTP only VPN</li>

</ul>

<h3 id="Battery">Battery usage indicator</h3>

<p>A new battery usage screen lets users see which apps and services are consuming 

battery power. If the user determines that a particular service or application is 

using too much power, they can take action to save the battery by

adjusting settings, stopping the application, or uninstalling the application.</p>

<h3 id="A11y">Accessibility</h3>

<p>Users will be able to download new accessibility services built

on the new Accessibility framework and enable them in Settings.</p>

<h2 id="AndroidMarketUpdates" style="clear:right">Android Market Updates</h2>

<div class="screenshot" style="margin-top:-35px">

New Android Market UI

</div>

<p>For devices with Android Market, the latest version improves the overall user experience and makes

it easier for users to discover great apps and games from developers.</p>

<ul>

  <li>At the homescreen, users can choose among <em>Apps</em>, <em>Games</em>, and <em>Downloads</em>.</li>

  <li>Inside a category, users can explore titles that are <em>Top paid</em>, <em>Top free</em>, and <em>Just in</em>.</li>

  <li>For each title, users can now see screenshots submitted by developers in addition to 

  reviews from other users.</li>

</ul>

<h2 id="PlatformTechnologies" style="clear:right">New Platform Technologies</h2>

<h3 id="SearchFramework">Expanded Search Framework</h3>

<p>The Android search framework has been redesigned and expanded to provide

third-party applications the opportunity to surface

content from their applications in Quick Search Box, the global search tool. 

To do this, developers will need to make their app "searchable" and provide 

suggestions in response to user queries.

To enable application search suggestions, users simply select each application from which 

they'd like to receive suggestions, under Searchable items in the Search settings.</p>

<h3 id="TTS">Text-to-speech engine</h3>

<p>Android 1.6 features a multi-lingual speech synthesis engine called Pico. 

It allows any Android application to "speak" a string of text with an accent that matches the language. 

The engine supports the following languages: English (American and British accents), French, 

Italian, German and Spanish. If you're using a T-Mobile G1 or Dream device, you'll need to download the 

SpeechSynthesis Data Installer from Android Market, which includes the "voices" needed by the 

text-to-speech engine.</p>

<h3 id="Gestures">Gestures</h3>

<p>A new gestures framework provides application developers with a framework for creating, storing, 

loading, and recognizing gestures and associating them with specific actions.</p>

<p>Developers can use the new GestureBuilder tool included in the Android 1.6 SDK to generate libraries 

of gestures to include with their application.</p>

<h3 id="A11y">Accessibility</h3>

<p>Android 1.6 provides a new accessibility framework. 

With this framework, developers can create accessibility plugins that respond to user input, 

such as making a sound when a new window is shown, vibrating when navigating to the top of 

a list, and providing spoken feedback.</p>

<h3 id="Screens">Expanded support for screen densities and resolutions</h3>

<p>Android 1.6 adds screen support that enables applications to be rendered properly on different 

display resolutions and densities. Developers can also specify the types of screens supported by their 

application.</p>

<h3 id="CDMA">Telephony support for CDMA</h3>

<p>Android 1.6 includes support for CDMA in the telephony stack.</p>

<h3 id="OpenCore">New version of OpenCore</h3>

<p>Android 1.6 includes the updated OpenCore 2 media engine, which has:</p>

<ul>

  <li>Support for OpenMAX encoders</li>

  <li>Support for additional audio codecs in AuthorEngine</li>

  <li>Improved buffering model supports shared buffers allocated in the decoder</li>

</ul>

<h3 id="LinuxKernel">2.6.29 Linux kernel</h3>

<p>Android 1.6 upgrades the Linux kernel from 2.6.27 to 2.6.29.</p>
