our issue tracker.</p>

<h2 id="ReleaseNotes">Release Notes</h2>

<p>June 25, 2014 - Initial Release of the L Developer Preview</p>

<h3 id="UserInterface">User interface</h3>

<ul>

<li>If your app launches an activity with

{@link android.app.Activity#startActivity startActivity()}

and an {@link android.content.Intent} set to

{@link android.content.Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET}, the

activity shows up as a separate task in the Recent apps screen. This is the

same behavior as though your app used {@code Intent.FLAG_ACTIVITY_NEW_DOCUMENT}

(see <a href="{@docRoot}preview/api-overview.html#Recents">Concurrent

documents and activities in the Recents screen</a>). If you want your activity

to remain in the same task that launched it, use

{@link android.app.Activity#startActivityForResult

startActivityForResult()} instead.</li>

<li>System-rendered shadows for user interface (UI) elements in views may

appear with visible spiky edges. To avoid this visual artifact, use a higher

<a href="{@docRoot}preview/material/views-shadows.html#elevation">view

elevation</a>.</li>

<li>On very tall or wide views, view shadows may appear with additional rough

visual artifacts around the view edges. To minimize this, avoid using view

shadows with very narrow views.</li>

<li>The {@code android.graphics.drawable.RippleDrawable} class does not

respond to pointer location changes, except when the drawable is set as a

{@link android.view.View} background.</li>

</ul>

<h3 id="Multimedia">Multimedia</h3>

<ul>

<li>The {@code android.hardware.camera2} APIs are supported only on Nexus 5

devices.</li>

<li>Saving a DNG file with the new {@code android.hardware.camera2.DngCreator}

API fails if lens shading compensation map generation is not enabled. To

capture images to DNG files, add the following code when creating your capture

requests:

<pre>

CaptureRequest.Builder stillCaptureRequest =

        mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE);

stillCaptureRequest.set(CaptureRequest.STATISTICS_LENS_SHADING_MAP_MODE,

        CaptureRequest.STATISTICS_LENS_SHADING_MAP_MODE_ON);

</pre></li>

<li>The {@code android.media.AudioTrack.write(float[], int, int, int)} method

currently does not work. Use the

{@link android.media.AudioTrack#write(short[], int, int)

AudioTrack.write(short[], int, int)} method instead.</li>

<li>Lockscreen security is currently not enforced when users start a Android

mirroring session from the Quick Settings shade.</li>

</ul>

<h3 id="UserInput">User input</h3>

<ul><li>The System UI may crash unexpectedly while the device is charging, if

	the locale is set to {@code fr} (FRENCH).</li></ul>

<h3 id="Wireless">Wireless and Connectivity</h3>

<ul>

<li>The {@code android.bluetooth.le} APIs are supported only on Nexus 5

devices.</li>

<li>You might encounter these issues while using Bluetooth LE scanning:

	<ul>

	<li><em>Settings</em> does not show all Bluetooth LE devices when a scan

		filter is set.</li>

	<li>System returns non-intuitive error messages during a Bluetooth LE scan,

		when Bluetooth is off.</li>

	<li>The {@code BluetoothLeScanner.startScan()} method starts failing after

		six concurrent scans with different callbacks.</li>

	</ul>

</li>

<li>You might encounter these issues while using Bluetooth LE advertising:

	<ul>

		<li>The device MAC address does not change for multiple advertising

		when the application processor is asleep.</li>

		<li>The TX Power Level is always 0 in advertising packets.</li>

	</ul>

</li>

</ul>

<h3 id="Enterprise">Enterprise</h3>

<ul>

<li>The device may crash unexpectedly in these situations when using

Android work functionality:

<ul>

<li>The user attempts to share a web page (via <strong>Menu &gt; Share</strong>)

from a non-Android work Chrome app to a Android work profile Gmail app.</li>

<li>The user attempts to share a web page via Bluetooth from a

Android work profile

Chrome app.</li>

<li>The user attempts to share a web page via Android Beam from a

Android work profile Chrome app.</li>

</ul>

</li>

<li>Deleting a Android work profile may take several minutes to complete. You

cannot create a new Android work profile until the deletion operation is over.</li>

</ul>

<h3 id="64bitsupport">64-bit support</h3>

<ul>

<li><p>If you are using the NDK to compile apps for 32- or 64-bit systems and

want to use the features provided in the L Developer Preview, download the

{@code android-ndk64-r10} package for your target platform from the

<a href="{@docRoot}tools/sdk/ndk/index.html">Android NDK page</a>. The

{@code android-ndk64-r10} package contains the L Developer Preview API

library (located under the {@code platforms/android-L/} API directory) for both

32- and 64-bit systems. The package also includes the {@code gcc-4.9} compiler

for both 32- and 64-bit apps.</p></li>

</ul>
