<p>
Android is an open source software stack for a wide range of mobile devices and
a corresponding open source project led by Google. This site offers the
information and source code you need to create custom variants of the Android
stack, port devices and accessories to the Android platform, and ensure your
devices meet compatibility requirements.

    <h3>What's New</h3>
<a href="{@docRoot}devices/tech/ota/device_code.html">
        <h4>FPS Value Customization</h4></a>
        <p>Android allows for a vendor-specific installing image but previously
        defined a private <code>animation_fps</code> variable that could not be overridden. The
        variable was changed from private to protected (so it can be customized), and
        the image generator can now optionally embed the FPS value (default is 20 FPS)
        into the generated image. See <strong><a
        href="{@docRoot}devices/tech/ota/device_code.html">OTA Device-Specific
        Code</a>.</strong></p>

<a href="{@docRoot}source/building-kernels.html">
        <h4>User Feedback Implemented</h4></a>
        <p>Input from the <strong>Site Feedback</strong> button has
        prompted the following fixes: new devices on <strong><a
        href="{@docRoot}source/building-kernels.html">Building Kernels</a></strong>,
        the significant motion sensor being identified as a wake-up sensor on
        <strong><a href="{@docRoot}devices/sensors/sensor-types.html">Sensor
        Types</a></strong>, a new path for example download in <strong><a
        href="{@docRoot}source/using-repo.html">Repo command reference</a></strong>, the correct
        formula for determining actual resistance on <strong><a
        href="{@docRoot}devices/accessories/headset/specification.html">Wired Audio Headset
        Specification</a></strong>, and a description of timestamp format on <strong><a
        href="{@docRoot}devices/input/getevent.html">Getevent</a></strong>.</p>

<a href="{@docRoot}devices/tech/ota/reduce_size.html">
        <h4>Reducing OTA Size</h4></a>
        <p>The Android build team has reduced the size of over-the-air (OTA)
        updates by eliminating unnecessary file changes between builds. And the team
        now offers those same improvements to the public by describing them in
        <strong><a href="{@docRoot}devices/tech/ota/reduce_size.html">Reducing OTA
        Size</a></strong> within the <strong><a
        href="{@docRoot}devices/tech/ota/index.html">OTA Updates</a></strong>
        section.</p>

<a href="{@docRoot}security/trusty/index.html">
        <h4>Trusty Components</h4></a>
        <p>See <strong><a
        href="{@docRoot}security/trusty/index.html">Trusty TEE</a></strong>
        for information about an optional set of components for a
        Trusted Execution Environment (TEE).
        Trusty consists of an operating system, drivers for the Android kernel (Linux),
        and libraries for Android systems software.</p>

<a href="{@docRoot}source/initializing.html">
        <h4>JDK 8 for Latest Platform Development</h4></a>
        <p>The master branch of Android now requires JDK 8 to build. See <strong><a
        href="{@docRoot}source/requirements.html">Requirements</a></strong>
        for a summary of Java versions by Android release. See <strong><a
        href="{@docRoot}source/initializing.html#installing-the-jdk">Setting up
