Timeline and Updates
|

</h2>
|
||
|
||
<p>
|
||
The Android Wear 2.0 Developer Preview runs from 18 May 2016 until the
|
||
final Android Wear public release to OEMs.
|
||
</p>
|
||
|
||
<p>
|
||
At key development milestones, we'll deliver updates for your development
|
||
and testing environment. In general you can expect updates in
|
||
approximately 6-week intervals. The release milestones are:
|
||
</p>
|
||
|
||
<ul>
|
||
<li>Milestone 1 (initial release, alpha)
|
||
</li>
|
||
|
||
<li>Milestone 2 (incremental update, beta)
|
||
</li>
|
||
|
||
<li>Milestone 3 (incremental update, beta)
|
||
</li>
|
||
|
||
<li>Milestone 4 (final APIs and official SDK, Play publishing)
|
||
</li>
|
||
|
||
<li>Near-final system image
|
||
</li>
|
||
|
||
<li>Final release to OEMs
|
||
</li>
|
||
</ul>
|
||
|
||
<p>
|
||
Each update includes an updated support library, preview system images,
|
||
emulator, reference documentation, and API diffs.
|
||
</p>
|
||
|
||
<p>
|
||
The first three milestones provide an early test and development
|
||
environment to help you identify compatibility issues in your current
|
||
apps and plan migration or feature work needed to target the new
|
||
platform. This is the priority period in which to give us your feedback
|
||
on features and APIs and file compatibility issues — for all of these,
|
||
please use the <a href="https://g.co/wearpreviewbug">issue tracker</a>.
|
||
You can expect some API changes across
|
||
these updates.
|
||
</p>
|
||
|
||
<p>
|
||
At milestone 4, you'll have access to the final Android Wear 2.0
|
||
APIs and SDK to develop with, as well as near-final system images to test
|
||
system behaviors and features. Android Wear 2.0 will use the Android N
|
||
API level at this time. You can begin final compatibility testing of your
|
||
legacy apps and refine any new code that is using the Android Wear 2.0
|
||
APIs or features.
|
||
</p>
|
||
|
||
<p>
|
||
As you test and develop on Android Wear 2.0, we strongly recommend
|
||
keeping your development environment up-to-date as updates are released.
|
||
</p>
|
||
|
||
<p>
|
||
We'll notify you when updates are available via the Android Developers
|
||
Blog, as well as via this site and the <a href=
|
||
