+
+Hardware System Images
+
+
+ These system images allow you to install a preview version of the platform on a physical device for
+ testing. By configuring a device with one of these images, you can install and test your app to
+ see how it performs on the next version of the platform. The process of installing a system image
+ on a device removes all data from the device, so you should backup your data before
+ installing a system image.
+
+
+
+ Warning: The following Android system images are previews and are subject to change. Your
+ use of these system images is governed by the Android SDK Preview License Agreement. The Android
+ preview system images are not stable releases, and may contain errors and defects that can result
+ in damage to your computer systems, devices, and data. The preview Android system images are not
+ subject to the same testing as the factory OS and can cause your phone and installed services and
+ applications to stop working.
+
+
+
+
+Install an Image to a Device
+
+
+ In order to use a device image for testing, you must install it on a compatible device. Follow
+ the instructions below to install a system image:
+
+
+
+ - Download and uncompress one of the system image packages listed here.
+ - Backup any data you want to preserve from the device.
+ - Follow the instructions at
+ developers.google.com/android
+ to flash the image onto your device.
+
+
+Updating a Device with the Preview
+
+
+ Once you have installed a preview system image on a development device, the device is upgraded
+ automatically with the next preview release through over-the-air (OTA) updates. When the update
+ is available, the device displays notification that an update is available and allows you to
+ install it. You can also manually install the next preview image by repeating the procedure in
+ the previous section.
+
+
+Revert a Device to Factory Specifications
+
+
+ If you want to uninstall the preview and revert the device to factory specifications, go to
+ developers.google.com/android and
+ download the image you want to flash to for your device. Follow the instructions on that page to
+ flash the image to your device.

+
+@jd:body
+
+
+
+
+ The Android M Developer Preview gives you an opportunity to ensure your apps work with the next
+ version of the platform. This preview includes a number of APIs and behavior changes that can
+ impact your app, as described in the API
+ Overview and Behavior Changes. In testing
+ your app with the preview, there are some specific system changes that you should focus on to
+ ensure that users have a good experience.
+
+
+
+ This guide describes the what and how to test preview features with your app. You should
+ prioritize testing of these specific preview features, due to their high potential impact on your
+ app's behavior:
+
+
+
+
+
+ For more information about how to set up devices or virtual devices with a preview system image
+ for testing, see Set up the Preview SDK.
+
+
+
+Testing Permissions
+
+
+ The new Permissions model
+ changes the way that permissions are allocated to your app by the user. Instead of granting all
+ permissions during the install procedure, your app must ask the user for individual permissions
+ at runtime. For users this behavior provides more granular control over each app’s activities, as
+ well as better context for understanding why the app is requesting a specific permission. Users
+ can grant or revoke the permissions granted to an app individually at any time. This feature of
+ the preview is most likely to have an impact on your app's behavior and may prevent some of your
+ app features from working, or they may work in a degraded state.
+
+
+
+ This change affects all apps running on the new platform, even those not targeting the new
+ platform version. The platform provides a limited compatibility behavior for legacy apps, but you
+ should begin planning your app’s migration to the new permissions model now, with a goal of
+ publishing an updated version of your app at the official platform launch.
+
+
+
+Test tips
+
+
+ Use the following test tips to help you plan and execute testing of your app with the new
+ permissions behavior.
+
+
+
+ - Identify your app’s current permissions and the related code paths.
+ - Test user flows across permission-protected services and data.
+ - Test with various combinations of granted/revoked permission.
+ - Use the {@code adb} tool to manage permssions from the command line:
+
+
+ - Analyze your app for services that use permissions.
+
+
+Test strategy
+
+
+ The permissions change affects the structure and design of your app, as well as
+ the user experience and flows you provide to users. You should assess your app’s current
+ permissions use and start planning for the new flows you want to offer. The official release of
+ the platform provides compatibility behavior, but you should plan on updating your app and not
+ rely on these behaviors.
+
+
+
+ Identify the permissions that your app actually needs and uses, and then find the various code
+ paths that use the permission-protected services. You can do this through a combination of
+ testing on the new platform and code analysis. In testing, you should focus on opting in to
+ runtime permissions by changing the app’s {@code targetSdkVersion} to the preview version. For
+ more information, see Set up the Preview SDK.
+
+
+
+ Test with various combinations of permissions revoked and added, to highlight the user flows that
+ depend on permissions. Where a dependency is not obvious or logical you should consider
+ refactoring or compartmentalizing that flow to eliminate the dependency or make it clear why the
+ permission is needed.
+
+
+
+ For more information on the behavior of runtime permissions, testing, and best practices, see the
+ Permissions developer
+ preview page.
+
+
+
+Testing Doze and App Standby
+
+
+ The power saving features of Doze and App Standby limit the amount of background processing that
+ your app can perform when a device is in an idle state or while your app is not in focus. The
+ restrictions the system may impose on apps include limited or no network access,
+ suspended background tasks, suspended Notifications, ignored wake requests, and alarms. To ensure
+ that your app behaves properly with these power saving optimizations, you should test your app by
+ simulating these low power states.
+
+
+Testing your app with Doze
+
+To test Doze with your app:
+
+
+- Configure a hardware device or virtual device with a M Preview system image.
+- Connect the device to your development machine and install your app.
+- Run your app and leave it active.
+- Simulate the device going into Doze mode by running the following commands:
+
+
+$ adb shell dumpsys battery unplug
+$ adb shell dumpsys deviceidle step
+$ adb shell dumpsys deviceidle -h
+
+
+
+ - Observe the behavior of your app when the device is re-activated. Make sure it
+ recovers gracefully when the device exits Doze.
+
+
+
+Testing apps with App Standby
+
+To test the App Standby mode with your app:
+
+
+ - Configure a hardware device or virtual device with a M Preview system image.
+ - Connect the device to your development machine and install your app.
+ - Run your app and leave it active.
+ - Simulate the app going into standby mode by running the following commands:
+
+
+$ adb shell am broadcast -a android.os.action.DISCHARGING
+$ adb shell am set-idle <packageName> true
+
+
+
+ - Simulate waking your app using the following command:
+
$ adb shell am set-idle <packageName> false
+
+ - Observe the behavior of your app when it is woken. Make sure it recovers gracefully
+ from standby mode. In particular, you should check if your app's Notifications and background
+ jobs continue to function as expected.
+
+
+Auto Backup for Apps and Device-Specific Identifiers
+
+If your app is persisting any device-specific identifiers, such as Google
+Cloud Messaging registration ID, in internal storage,
+make sure to follow best practices to exclude the storage
+location from auto-backup, as described in Auto
+Backup for Apps.

Other than this, no other person or company shall be third party beneficiaries to the License Agreement.
+
+14.5 EXPORT RESTRICTIONS. THE PREVIEW IS SUBJECT TO UNITED STATES EXPORT LAWS AND REGULATIONS. YOU MUST COMPLY WITH ALL DOMESTIC AND INTERNATIONAL EXPORT LAWS AND REGULATIONS THAT APPLY TO THE PREVIEW. THESE LAWS INCLUDE RESTRICTIONS ON DESTINATIONS, END USERS AND END USE.
+
+14.6 The License Agreement may not be assigned or transferred by you without the prior written approval of Google, and any attempted assignment without such approval will be void. You shall not delegate your responsibilities or obligations under the License Agreement without the prior written approval of Google.
+
+14.7 The License Agreement, and your relationship with Google under the License Agreement, shall be governed by the laws of the State of California without regard to its conflict of laws provisions. You and Google agree to submit to the exclusive jurisdiction of the courts located within the county of Santa Clara, California to resolve any legal matter arising from the License Agreement. Notwithstanding this, you agree that Google shall still be allowed to apply for injunctive remedies (or an equivalent type of urgent legal relief) in any jurisdiction.

+
+
+ Developer Preview 3 is now available
+
+
Includes final SDK and near-final system images
+
+
+ Welcome to the Android M Developer Preview, a program that gives you
+ everything you need to test and optimize your apps for the next version of
+ Android. It's free, and you can get started right away just by downloading
+ the M Developer Preview tools.
+
+
+
+
+
+
+
+ Hardware and emulator system images
+
+
+
+ Run and test your apps on Nexus 5, 6, 9, and Player (for TV), as well
+ as emulator.
+
+
+
+
+
+ Latest platform code
+
+
+
+ We’ll provide multiple updates during the Preview, so you’ll be testing
+ against the latest platform changes.
+
+
+
+
+
+ Updates delivered by OTA
+
+
+
+ You can get updates over-the-air, once you’ve flashed a
+ device to the initial preview.
+
+
+
+
+
+
+
+
+
+ New behaviors and capabilities
+
+
+
+ Start work early to support new platform behaviors such as
+ the new runtime permissions model and power-saving features.
+
+
+
+
+
+ Priority window for developer-reported issues
+
+
+
+ During the first several weeks we’ll give priority to developer-reported
+ issues, so test and give feedback as soon as possible.
+
+
+
+
+
+
+
+ Timeline and updates
+
+
+
+ The M Developer Preview runs from May 28 until the final Android M public release planned for Q3
+ 2015.
+
+
+
+ At key development milestones, we’ll deliver updates for your test devices.
+ The milestones are
+
+
+
+ -
+ Preview 1 (available).
+
+
+ -
+ Preview 2 (available).
+
+
+ -
+ Preview 3
+ (final APIs and official Android 6.0 SDK, available).
+
+
+
+
+ These updates culminate in the official Android 6.0 SDK (now available),
+ which lets you build with the final APIs for the new version of Android, as well as
+ near-final system images to let you test system behaviors and features.
+
+
+
+ As you test and develop on Android M, we strongly recommend keeping
+ your development environment up-to-date as Preview updates are released.
+ To make the process easier, we'll deliver updates over-the-air
+ (OTA) to devices already flashed to a Preview build, as well as
+ providing system images that you can download and flash manually.
+
+
+ Note: Developer Preview 3 includes final APIs and near-final
+ system images available by both download and OTA. At the full public release of
+ Android M later in Q3, final system images will be available by download only,
+ so you'll need to flash manually to
+ your test devices.
+
+
+
+ We’ll notify you when Preview updates are available via the Android Developers Blog, as
+ well as this site and the
+ Android M Developer Community.
+
+
+
+
+
+ The M Developer Preview includes everything you need to test your existing
+ apps on a variety of screen sizes, network technologies, CPU/GPU chipsets,
+ and hardware architectures.

+
+ Use these support resources as you test and develop on the M
+ Developer Preview:
+
+
+
+ - M
+ Developer Preview Issue Tracker is your primary feedback
+ channel. You can report bugs, performance issues, and general
+ feedback through the issue tracker. You can also check for known issues
+ and find workaround steps.
+
+
+ - The Android M Developer
+ Community is a Google+ community where you can connect with
+ other developers working with Android M. You can share
+ observations or ideas or find answers to questions about Android M.
+
+
+
+
+
+ Final SDK, targeting, and publishing
+
+
+
+
With Developer Preview 3, the platform APIs are now official (API level 23) and the
+ official Android 6.0 SDK is now available. We recommend updating your environment
+ right away through Android Studio. Once you've updated your environment, you can target
+ the new API level, compile against the new platform, and publish at your convenience
+ to Google Play (including alpha, beta, or release channels).
+
+
If you want to opt out
+ of compatibility behaviors (which is strongly recommended),
+ you can target the Android 6.0 platform by setting your app's targetSdkVersion
+ to “23”.
+
+
+ Before releasing an app that targets API level 23, we strongly
+ recommend distributing it to a group of testers through the new
+ beta testing features available in the Google Play Developer Console. See the
+ Help
+ Center article for more information.
+
+
+
+ How to get started
+
+
+
+ To get started testing your app with Android M:
+
+
+
+ - Review the API Overview
+ and Behavior Changes to get an
+ idea of what's new and how it affects your apps. In particular, learn about
+ the new runtime
+ permissions model, power-saving features, and auto backup.
+
+
+ - Set up your environment by following the instructions for
+ Setting up the Preview SDK
+ and configuring test devices.
+
+
+ - Follow the
+ flashing instructions to flash the latest M developer preview system image
+ for Nexus 5, 6, 9, and Player. Once you've flashed your development device,
+ Preview updates will be delivered through over-the-air (OTA) updates.
+
+
+ - Review the API
+ Reference and M Preview
+ samples to gain more insight into new API features and how to use them in
+ your app.
+
+
+ - Join the Android M
+ Developer Community to get the latest news and connect with other
+ developers working with the new platform.
+
+
+
+
+ Thank you for your participation in the Android M Developer Preview program!

+
+
+With Developer Preview 3, the official Android 6.0 SDK is now available from the Android SDK
+Manager. This document assumes that you are familiar with Android app development, such
+as using the Android SDK Manager and creating projects. If you are new to
+Android, see Building Your First
+App training lesson first.
+
+
+Get Android Studio 1.3
+
+
+ It is highly recommended that you install the Android Studio 1.3 to work best with
+ the Android 6.0 SDK. Please update your Android Studio installation to version 1.3 or
+ higher, or follow the instructions for
+ Installing Android Studio.
+
+
+
+Get the Android 6.0 SDK
+
+To add the Android 6.0 SDK components to your development environment:
+
+
+ - Launch Android Studio 1.3 or higher.
+
+
+ - Open the Settings window (on Windows, you can do this
+ by choosing File > Settings). Choose the
+ Appearance & Behavior > System
+ Settings > Updates panel.
+
+
On Mac OS X, you can find the Appearance &
+ Behavior panel
+ in Android Studio's Preferences window.
+
+
+ - On the Updates panel, choose the option for
+ Automatically check updates for Android SDK: Preview Channel.
+
+
+ - Launch the Android SDK Manager. (With Android Studio 1.3,
+ the SDK Manager is integrated into Android Studio instead of being a
+ standalone application.)
+
+
+ - Under the Platforms section, select Android 6.0.
+
+
+ - In the Tools section, select the latest Android
+ SDK Tools, Platform-tools, and
+ Build-tools.
+
+
+ - Click Install packages and accept the licensing
+ agreement for all of the packages.
+
+
+ - Verify that the Android 6.0 SDK is installed by opening the
+ Settings window and choosing the Appearance & Behavior
+ > System Settings > Android SDK panel.
+
+ - On the Android SDK panel, choose
+ the SDK Platforms tab. Android 6.0 should be listed as Installed. Also, open the
+ SDK Tools tab to verify that the latest tools are
+ installed.
+
+
+After completing these steps, the preview components are available in your development
+ environment.
+
+
+Create or Update a Project
+
+
+ In order to use the preview APIs, you must create or update a development project to use
+ the preview components.
+
+
+
+Create a new project
+
+
+ We recommend using Android Studio to create a project with the preview. Follow the steps
+ described in Creating a Project
+ until you arrive at the Form Factors screen in the project wizard. Then perform
+ the following steps to create a project configured for the preview.
+
+
+
+ - Check Phone and Tablet.
+ - Select API 23: Android 6.0 (Marshmallow) in Minimum
+ SDK.
+
+
+
+Update an existing project
+
+
+ For existing projects, if you are using Android 6.0 APIs (API level 23) you must
+ modify the project configuration. In your development environment, open the
+ build.gradle file for your module and
+ set these values as follows:
+
+
+
+ compileSdkVersion is set to '23'targetSdkVersion is set to '23'
+
+
+Set Up for Testing
+
+
+ Testing an app with the preview requires that you have a device or virtual device configured with
+ the preview version of the platform. If you have a compatible device, you can install the preview
+ platform for testing. Otherwise, you can configure a virtual device for testing.
+
+
+Set up a physical device
+
+
+ If you have a Nexus 5, Nexus 6, Nexus 9, or Android TV, you can install a preview
+ system image on these devices for testing your app.
+ You can set up a virtual device with the preview version of the platform from within Android Studio
+ using the Android Virtual Device Manager tool.
+
+
+
+ Important: Installing a preview image on a device removes all data from
+ it, so you should backup any data before installing a preview image.
+
+
+Set up a virtual device
+
+
+ You can set up virtual device with the preview version of the platform from within Android Studio
+ using the Android Virtual Device Manager tool.
+
+
+To create an AVD with the AVD Manager:
+
+
+ - Install the Preview SDK in your development environment, as described
+ in Setting Up the Preview
+ SDK.
+ - Follow the steps in
+ Managing AVDs with AVD
+ Manager. Use the following settings:
+
+ - Device: Nexus 5, Nexus 6, Nexus 9, or Android TV
+ - Target:
+ Android M (Preview) - API Level M
+ - ABI: x86
+
+
+
+
+
+ For more information about creating virtual devices for testing, see Managing Virtual Devices.

+
+ Developer Preview 3 is now available
+
+
Includes final SDK and near-final system images
+
+
+ Two primary support channels are available to you when developing and testing
+ with the Android M Developer Preview. If you've encountered bugs or have
+ feedback about the M Developer Preview, you can create an issue on
+ our issue tracker. We'll triage the issue for further review and provide
+ updates as needed.
+
+
+
+ To discuss issues or ideas with other developers working with Android M, join
+ the M Developer Preview Google+
+ community.
+
+
+
+ Developer Preview 3
+
+
+
+
+
+
+ Date: August 2015
+ Build: MPA44I
+ Hardware support: Nexus 5, 6, 9, Player
+ Emulator support: x86 & ARM 32/64-bit
+ Google Play services: 7.8
+
+
+
+
+ Developer Preview 3 is the final incremental update
+ to the Android M preview platform that was originally released in May 2015.
+ The update includes final APIs and the official Android 6.0 SDK,
+ 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.
+
+
+
+ If you are currently developing or testing on Android M, you should update
+ your environment as soon as possible, so that
+ you can begin final compatibility testing in preparation for
+ the public release to device manufacturers later this year.
+
+Updating to the Android 6.0 SDK and the latest
+ system images 3 ensures that you are building against final
+ platform APIs in API level 23 and testing
+ against final behaviors. If you are just getting started,
+ follow the instructions in Set up the Preview SDK.
+
+
+
+ What's included
+
+
+
+ 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.
+
+
+
+ -
+ SDK platform and system images (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).
+
+
+ -
+ Updated documentation. The Behavior Changes, API Overview, and Permissions documents have
+ been updated to reflect the latest changes in the platform. An updated
+ Developer Documentation download
+ package is available, including full reference docs and API diff
+ reports. Reference documentation is also now available online.
+
+
+ -
+ Translations 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.
+
+
+ - The Android M code samples are also
+ updated to account for API and behavior changes:
+
+ -
+ RuntimePermissions
+ and RuntimePermissionsBasic
+ are updated to reflect latest permissions API changes, including
+
shouldShowRequestPermissionRationale().
+
+ -
+ Other samples are updated to support runtime permissions.
+
+
+
+
+
+
+ Key changes
+
+
+ - General
+
+ - Updated the Fingerprint API to enables better error reporting,
+ better fingerprint enrollment experience, and enumeration support for greater
+ reliability.
+ - 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.
+
+
+ - Permission changes
+
+ - Updated the user interface for permissions and enhanced some of the permissions
+ behaviors.
+ - 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.
+
+
+ - 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.
+
+
+
+
+
+
+ For a complete list of changes, including renamed and removed APIs, see the API Diff report for
+ API level 22 to 23.
+
+
+
+ Known issues
+
+
+
+ - General issues:
+
+ - On LTE devices, including Nexus 9, GPS is not functioning properly, which may
+ interfere with navigation services.
+
+ - During Hangouts calls, users may experience distorted or low audio on some devices.
+
+ - 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.
+
+
+
+
+
+
+ For a complete list of reported issues, please refer to the open issues list on the
+ Developer Preview issue tracker.
+
+
+
+ Get Developer Preview 3
+
+
+
+ You can download the official Android 6.0 SDK platform and
+ Developer Preview 3 emulator images from the SDK Manager.
+
+
+
+ Developer Preview 3 system images for supported Nexus devices are available
+ by download and by over-the-air (OTA) update. The OTA update is available
+ only to supported devices that are currently running a Developer Preview build.
+ If your device is running a Developer Preview build, you should automatically receive
+ the OTA update within a few days of availability.
+
+
+
+ For instructions on how to download and flash your device to the latest Developer
+ Preview, see the links and instructions on the Downloads page.

+
+
+
+
+
+
+ Date: July 2015
+ Builds: MPZ79M (Nexus 5, 6, 9), MPZ79N (Nexus Player)
+ Hardware support: Nexus 5, 6, 9, Player

+
+
+
+
+ Android M Developer Preview 2 is an incremental update 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
+ update your environment 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 Set up the Preview SDK, then update your
+ environment for Developer Preview 2.
+
+
+
+ What's included
+
+
+
+ Developer Preview 2 includes an updated SDK with system images,
+ documentation, and samples for developing against the latest Android M
+ platform.
+
+
+
+ -
+ SDK platform and system images (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).
+
+
+ -
+ Updated documentation. The Behavior Changes, API Overview, and Permissions documents have
+ been updated to reflect the latest changes in the platform. An updated
+ Developer Documentation download
+ package is available, including full reference docs and API diff
+ reports.
+
+
+ -
+ Translations 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).
+
+
+ - The Android M code samples are also
+ updated to account for API and behavior changes:
+
+ -
+ RuntimePermissions
+ / RuntimePermissionsBasic
+ are updated to reflect latest permissions API changes, including
+
shouldShowRequestPermissionRationale().
+
+ -
+ FingerprintDialog
+ 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.
+
+
+
+
+
+
+ Key changes
+
+
+
+ - Permissions changes
+
+ - The
android.permission.USE_FINGERPRINT permission now
+ has "normal" protection level, so it is no longer necessary to request
+ this permission directly from the user. The USE_FINGERPRINT
+ permission enables fingerprints to be enabled for authentication, but
+ does not give the requesting app access to the enrollment/fingerprint
+ administration flow.
+
+
+ - The
android.permission.WRITE_EXTERNAL_STORAGE 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 READ_EXTERNAL_STORAGE and
+ WRITE_EXTERNAL_STORAGE are members of the
+ STORAGE permission group.
+
+
+ - Remote Bluetooth/Wi-Fi MAC's now require either the
+
android.permission.ACCESS_COARSE_LOCATION or
+ android.permission.ACCESS_FINE_LOCATION permission.
+
+
+ - Some accounts and identity permissions are moved to
+
CONTACTS permissions group and others are removed or granted
+ based on account type. In particular,
+ android.permission.USE_CREDENTIALS,
+ android.permission.MANAGE_ACCOUNTS, and
+ android.permission.AUTHENTICATE_ACCOUNTS are ungrouped
+ pending further changes in a later release.
+
+
+ - The Wi-Fi permissions
+
android.permission.CHANGE_WIFI_STATE,
+ android.permission.CHANGE_WIMAX_STATE, and
+ android.permission.CHANGE_WIFI_MULTICAST_STATE now have
+ protection level "normal".
+
+
+ - The Bluetooth permissions
android.permission.BLUETOOTH
+ and android.permission.BLUETOOTH_ADMIN now have protection
+ level "normal".
+
+
+ - Bookmarks and subscribed feeds permissions are removed.
+
+
+ - Apps included in the system image are no longer granted dangerous
+ permissions automatically. All apps should check for and request
+ permissions at runtime.
+
+
+ - Introduces the utility method
+
Activity.shouldShowRequestPermissionRationale(String), 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 Permissions
+ developer guide.
+
+
+
+
+ - Other changes
+
+ - The
android.app.AssistContent and
+ android.app.AssistStructure classes are moved into a new
+ package, android.app.assist.
+
+
+ - Bluetooth Stylus APIs are updated and include new callback events.
+ The
View.OnStylusButtonPressListener class is renamed to
+ View.OnContextClickListener and
+ GestureDetector.OnStylusButtonPressListener class to
+ GestureDetector.OnContextClickListener.
+
+
+
+
+
+
+ For a complete list of changes, including renamed and removed APIs, please
+ refer to the API Diff Reports included in the Developer Documentation download package.
+
+
+
+ Known issues
+
+
+
+ - General issues:
+
+ - The system Messenger app crashes on the 64-bit emulator.
+ - 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 Settings > Apps > Show
+ system > Contacts Storage. Select "Storage" and then
+ Clear data.
+ - In YouTube app, it's not possible to share a video. The share window is
+ blank.
+ - 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.
+
+
+
+ - Issues specific to MPZ79N on Nexus Player:
+
+ - Bluetooth share crashes after clearing data. Please do not
+ clear app data for system services, otherwise you will need to Factory
+ Reset your device
+ - Remote control can experience intermittent connectivity issues.
+ - Movies show black screen with some ANRs on exiting the video.
+ - In YouTube app, lower-resolution videos have a green bar at the top
+ and some color-ghosting
+
+
+
+
+
+
+ For a complete list of reported issues, please refer to the open issues list on the
+ Developer Preview issue tracker.
+
+
+
+ Get Developer Preview 2
+
+
+
+ You can download the Developer Preview 2 platform and emulator images from
+ the SDK Manager.
+
+
+
+ Developer Preview 2 system images for supported Nexus devices are available
+ by download and by over-the-air (OTA) update. The OTA update is available
+ only to supported devices that are currently running Developer Preview 1. If
