Android M Developer Preview 2 is an <strong>incremental update</strong> to
|
|
|
|
|
the Android M preview platform that was originally released in May 2015. The
|
|
|
|
|
update includes a variety of enhancements and bug fixes made across the
|
|
|
|
|
system, including those related to issues reported by developers through the
|
|
|
|
|
external issue tracker.

If you are currently developing or testing on Android M, you should
|
|
|
|
|
<strong>update your environment</strong> to Developer Preview 2 as soon as
|
|
|
|
|
possible. This ensures that you are building with the latest platform APIs
|
|
|
|
|
and testing against the latest behaviors. If you are just getting started
|
|
|
|
|
with the Android M Developer Preview SDK, follow the instructions in <a href=
|
|
|
|
|
"/preview/setup-sdk.html">Set up the Preview SDK</a>, then update your
|
|
|
|
|
environment for Developer Preview 2.

Key changes

|
|
|
|
</h3>
|
|
|
|
|
|
|
|
|
|
<ul>
|
|
|
|
|
<li>Permissions changes
|
|
|
|
|
<ul>
|
|
|
|
|
<li>The <code>android.permission.USE_FINGERPRINT</code> permission now
|
|
|
|
|
has "normal" protection level, so it is no longer necessary to request
|
|
|
|
|
this permission directly from the user. The <code>USE_FINGERPRINT</code>
|
|
|
|
|
permission enables fingerprints to be enabled for authentication, but
|
|
|
|
|
does not give the requesting app access to the enrollment/fingerprint
|
|
|
|
|
administration flow.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>The <code>android.permission.WRITE_EXTERNAL_STORAGE</code> permission
|
|
|
|
|
has protection level "dangerous", meaning that apps wanting to write to
|
|
|
|
|
external storage will need to request permission from the user at
|
|
|
|
|
runtime. Both <code>WRITE_EXTERNAL_STORAGE</code> and
|
|
|
|
|
<code>WRITE_EXTERNAL_STORAGE</code> are members of the
|
|
|
|
|
<code>STORAGE</code> permission group.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Remote Bluetooth/Wi-Fi MAC's now require either the
|
|
|
|
|
<code>android.permission.LOCATION_FINE</code> or
|
|
|
|
|
<code>android.permission.LOCATION_COURSE</code> permission.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Some accounts and identity permissions are moved to
|
|
|
|
|
<code>CONTACTS</code> permissions group and others are removed or granted
|
|
|
|
|
based on account type. In particular,
|
|
|
|
|
<code>android.permission.USE_CREDENTIALS</code>,
|
|
|
|
|
<code>android.permission.MANAGE_ACCOUNTS</code>, and
|
|
|
|
|
<code>android.permission.AUTHENTICATE_ACCOUNTS</code> are ungrouped
|
|
|
|
|
pending further changes in a later release.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>The Wi-Fi permissions
|
|
|
|
|
<code>android.permission.CHANGE_WIFI_STATE</code>,
|
|
|
|
|
<code>android.permission.CHANGE_WIMAX_STATE</code>, and
|
|
|
|
|
<code>android.permission.CHANGE_WIFI_MULTICAST_STATE</code> now have
|
|
|
|
|
protection level "normal".
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>The Bluetooth permissions <code>android.permission.BLUETOOTH</code>
|
|
|
|
|
and <code>android.permission.BLUETOOTH_ADMIN</code> now have protection
|
|
|
|
|
level "normal".
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Bookmarks and subscribed feeds permissions are removed.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Apps included in the system image are no longer granted dangerous
|
|
|
|
|
permissions automatically. All apps should check for and request
|
|
|
|
|
permissions at runtime.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Introduces the utility method
|
|
|
|
|
<code>Activity.shouldShowRequestPermissionRationale(String)</code>, which
|
|
|
|
|
lets your app see whether users have previously rejected a permission
|
|
|
|
|
request. This lets you know that your app should explain the the user why
|
|
|
|
|
it needs that permission. For more information see the <a href=

package, <code>android.app.assist</code>.
|

|
|
|
|
|
|
|
|
|
|
<li>Bluetooth Stylus APIs are updated and include new callback events.
|
|
|
|
|
The <code>View.OnStylusButtonPressListener</code> class is renamed to
|
|
|
|
|
<code>View.OnContextClickListener</code> and
|
|
|
|
|
<code>GestureDetector.OnStylusButtonPressListener</code> class to <code>

Known issues

</h3>

<ul>
|
|
|
|

<li>The system Messenger app crashes on the 64-bit emulator.

</li>
|
|
|
|
|
|
|
|
|
|
<li>After updating to Developer Preview 2, Contacts sync experiences
|
|
|
|
|
intermittent issues. The workaround is to clear and re-sync Contact Storage
|
|
|
|
|
data after update. To clear data, go to <strong>Settings > Apps > Show
|
|
|
|
|
system > Contacts Storage</strong>. Select "Storage" and then
|
|
|
|
|
<strong>Clear data</strong>.
|

</li>
|
|
|
|
|

<li>In YouTube app, it's not possible to share a video. The share window is

|
blank.
|
|
|
|
|
</li>
|
|
|
|
|
|
|
|
|
|
<li>Android For Work Profile setup is not working properly, so you won't be
|
|
|
|
|
able to create a new Work Profile after you update. As a workaround, make
|
|
|
|
|
sure to create the Work Profiles you need in Developer Preview 1 before
|
|
|
|
|
updating to Developer Preview 2.
