|
|
<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.RippableDrawable} 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>Portions of the internal audio pipeline do not support floating-point format.</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>
|
|
</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></ul>
|
|
|
|
<h3 id="Enterprise">Enterprise</h3>
|
|
<ul>
|
|
<li>The device may crash unexpectedly in these situations when using
|
|
Android for Work functionality:
|
|
<ul>
|
|
<li>The user attempts to share a webpage (via <strong>Menu > Share</strong>)
|
|
from a non-managed Chrome app to a managed Gmail app.</li>
|
|
<li>The user attempts to share a webpage via Bluetooth from a managed Chrome app.</li>
|
|
<li>The user attempts to share a webpage via Android Beam from a managed Chrome app.</li>
|
|
</ul>
|
|
</li>
|
|
<li>Deleting the managed work profile (profile owner) may take several minutes
|
|
to complete. You cannot create a new managed profile until the deletion
|
|
operation is over.</li>
|
|
</ul>
