| Developer Preview 3 is the <strong>final incremental update</strong> |
| to the Android M preview platform that was originally released in May 2015. |
| The update includes <strong>final APIs and the official Android 6.0 SDK</strong>, |
| as well as near-final system images for testing your apps. The |
| updated system images bring a variety of fixes and enhancements across |
| the system, including those related to issues reported by developers |
| through the external issue tracker. |
| </p> |
| |
| <p> |
| If you are currently developing or testing on Android M, you should <strong>update |
| your environment</strong> as soon as possible, so that |
| you can begin <strong>final compatibility testing</strong> in preparation for |
| the public release to device manufacturers later this year.</p> |
| |
| <p class="important">Updating to the Android 6.0 SDK and the latest |
| system images 3 ensures that you are building against final |
| platform APIs in <strong>API level 23</strong> and testing |
| against final behaviors. If you are just getting started, |
| follow the instructions in <a href= |
| "/preview/setup-sdk.html">Set up the Preview SDK</a>. |
| </p> |
| |
| <h3> |
| What's included |
| </h3> |
| |
| <p> |
| Developer Preview 3 includes the official Android 6.0 |
| SDK as well as updated preview system images, documentation, |
| and samples for developing against the Android 6.0 |
| development platform. |
| </p> |
| |
| <ul> |
| <li> |
| <strong>SDK platform</strong> and <strong>system images</strong> (Nexus and |
| emulator) for building and testing. You can download the Android 6.0 SDK and tools from |
| the SDK Manager, and the system images are available by over-the-air (OTA) |
| update or download (see below). |
| </li> |
| |
| <li> |
| <strong>Updated documentation</strong>. The <a href= |
| "{@docRoot}preview/behavior-changes.html">Behavior Changes</a>, <a href= |
| "{@docRoot}preview/api-overview.html">API Overview</a>, and <a href= |
| "{@docRoot}preview/features/runtime-permissions.html">Permissions</a> documents have |
| been updated to reflect the latest changes in the platform. An updated |
| <a href="/preview/download.html">Developer Documentation download |
| package</a> is available, including full reference docs and API diff |
| reports. Reference documentation is also now <a |
| href="{@docRoot}reference/packages.html">available online</a>. |
| </li> |
| |
| <li> |
| <strong>Translations</strong> of the documentation are available. Use |
| the language selector at the bottom right corner of any page to switch |
| languages. Note that some of the translated docs are not yet updated for |
| Developer Preview 3. |
| </li> |
| |
| <li>The <a href="{@docRoot}preview/samples.html">Android M code samples</a> are also |
| updated to account for API and behavior changes: |
| <ul> |
| <li> |
| <a href= |
| "https://github.com/googlesamples/android-RuntimePermissions">RuntimePermissions</a> |
| and <a href= |
| "https://github.com/googlesamples/android-RuntimePermissionsBasic">RuntimePermissionsBasic</a> |
| are updated to reflect latest permissions API changes, including |
| <code>shouldShowRequestPermissionRationale()</code>. |
| </li> |
| <li> |
| Other samples are updated to support runtime permissions. |
| </li> |
| </ul> |
| </li> |
| </ul> |
| |
| <h3 id="changes"> |
| Key changes |
| </h3> |
| <ul> |
| <li>General |
| <ul> |
| <li>Updated the Fingerprint API to enables better error reporting, |
| better fingerprint enrollment experience, and enumeration support for greater |
| reliability.</li> |
| <li>Modified app access to BLE and Wi-Fi scans to require the location permisssion when they |
| target Android 6.0 (API level 23) or higher. Apps targeting API 22 or earlier can |
| still perform BTLE and WiFi scans, but only when they are in the foreground. While in the background, those apps will get no results from BTLE and WiFi scans.</li> |
| </ul> |
| </li> |
| <li>Permission changes |
| <ul> |
| <li>Updated the user interface for permissions and enhanced some of the permissions |
| behaviors.</li> |
| <li>The {@link android.Manifest.permission#GET_ACCOUNTS} permission is now a member of the |
| {@link android.Manifest.permission_group#CONTACTS} permission group and it has a |
| {@code android:protectionLevel} of {@code dangerous}. This change means that when |
| targeting Android 6.0 (API level 23), you must check for and request this permission if |
| your app requires it. |
| </li> |
| |
| <li>The {@code android.permission.READ_PROFILE} and {@code android.permission.WRITE_PROFILE} |
| permissions have been removed from the {@link android.Manifest.permission_group#CONTACTS} |
| permission group. |
| </li> |
| </ul> |
| </li> |
| </ul> |
| |
| <p> |
| For a complete list of changes, including renamed and removed APIs, see the API Diff report for |
| <a href="{@docRoot}sdk/api_diff/23/changes.html">API level 22 to 23</a>. |

| Known issues |
| </h3> |
| |
| <ul> |
| <li>General issues: |
| <ul> |
| <li>On LTE devices, including Nexus 9, GPS is not functioning properly, which may |
| interfere with navigation services. |
| </li> |
| <li>During Hangouts calls, users may experience distorted or low audio on some devices. |
| </li> |
| <li>The Google Apps Device Policy app bundled with MPA44G is unable to set up an Android for |
| Work Profile, so you cannot create a new Work Profile with that version of the app. This issue is |
| resolved in the Google Apps Device Policy app bundled with MPA44I. Other apps that provide Android |
| for Work functionality remain unaffected on either build. |

| environment for Developer Preview 2. |
| </p> |
| |
| <h3> |
| What's included |
| </h3> |
| |
| <p> |
| Developer Preview 2 includes an updated SDK with system images, |
| documentation, and samples for developing against the latest Android M |
| platform. |
| </p> |
| |
| <ul> |
| <li> |
| <strong>SDK platform</strong> and <strong>system images</strong> (Nexus and |
| emulator) for building and testing. You can download the updated tools from |
| the SDK Manager, and the system images are available by over-the-air (OTA) |
| update or download (see below). |
| </li> |
| |
| <li> |
| <strong>Updated documentation</strong>. The <a href= |
| "{@docRoot}preview/behavior-changes.html">Behavior Changes</a>, <a href= |
| "{@docRoot}preview/api-overview.html">API Overview</a>, and <a href= |
| "{@docRoot}preview/features/runtime-permissions.html">Permissions</a> documents have |
| been updated to reflect the latest changes in the platform. An updated |
| <a href="{@docRoot}preview/download.html">Developer Documentation download |
| package</a> is available, including full reference docs and API diff |
| reports. |
| </li> |

| <strong>Translations</strong> of the documentation are now available. Use |
| the language selector at the bottom right corner of any page to switch |
| languages. Note that some of the translated docs are not yet updated for |
| Developer Preview 2 (coming soon). |
| </li> |
| |
| <li>The <a href="{@docRoot}preview/samples.html">Android M code samples</a> are also |
| updated to account for API and behavior changes: |
| <ul> |
| <li> |
| <a href= |
| "https://github.com/googlesamples/android-RuntimePermissions">RuntimePermissions</a> |
| / <a href= |
| "https://github.com/googlesamples/android-RuntimePermissionsBasic">RuntimePermissionsBasic</a> |
| are updated to reflect latest permissions API changes, including |
| <code>shouldShowRequestPermissionRationale()</code>. |
| </li> |
| <li> |
| <a href= |
| "https://github.com/googlesamples/android-FingerprintDialog">FingerprintDialog</a> |
| adds a flow to ask for passwords when new fingerprints are added as |
| well as a preference if the app will use fingerprints as a method of |
| authentication. |
| </li> |
| </ul> |
| </li> |
| </ul> |
| |
| <h3 id="changes-p2"> |
| 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>READ_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.ACCESS_COARSE_LOCATION</code> or |
| <code>android.permission.ACCESS_FINE_LOCATION</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= |
| "{@docRoot}preview/features/runtime-permissions.html#explain-need">Permissions</a> |
| developer guide. |
| </li> |
| </ul> |
| </li> |
| |
| <li>Other changes |
| <ul> |
| <li>The <code>android.app.AssistContent</code> and |
| <code>android.app.AssistStructure</code> classes are moved into a new |
| package, <code>android.app.assist</code>. |
| </li> |
| |
| <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> |
| GestureDetector.OnContextClickListener</code>. |
| </li> |
| </ul> |
| </li> |
| </ul> |
| |
| <p> |

| Known issues |
| </h3> |
| |
| <ul> |
| <li>General issues: |
| <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>The bundled Google Apps Device Policy app included in Developer Preview 2 is unable to |
| properly set up an Android for Work Profile, so you cannot create a new Work Profile with this |
| app after you update. This issue is specific to the Google Apps Device Policy app, and not the |
| Android for Work platform (or our partner EMM providers). As a workaround for users of the |
| Google Apps Device Policy app, be sure to create a Work Profile in Developer Preview 1 before |
| updating to Developer Preview 2. |
| </li> |
| </ul> |
| </li> |
| <li>Issues specific to MPZ79N on Nexus Player: |
| <ul> |
| <li>Bluetooth share crashes after clearing data. Please <strong>do not |
| clear app data for system services</strong>, otherwise you will need to Factory |
| Reset your device</li> |
| <li>Remote control can experience intermittent connectivity issues. </li> |
| <li>Movies show black screen with some ANRs on exiting the video.</li> |
| <li>In YouTube app, lower-resolution videos have a green bar at the top |
| and some color-ghosting</li> |
