Update your target API level To better optimize your app for devices running Android , set your targetSdkVersion to "23" , install your app on an Android system image, test it, then publish the updated app with this change.

Fingerprint Authentication This release offers new APIs to let you authenticate users by using their fingerprint scans on supported devices, Use these APIs in conjunction with the Android Keystore system. Use an emulator to emulate fingerprint touch events with the following command. Use the same command to emulate fingerprint touch events on the lockscreen or in your app. Confirm Credential Your app can authenticate users based on how recently they last unlocked their device.

Assist API This release offers a new way for users to engage with your apps through an assistant. To provide the assistant with additional context from your app, follow these steps: Implement the Application. OnProvideAssistDataListener interface. In order to provide activity-specific contextual information, override the onProvideAssistData callback and, optionally, the new onProvideAssistContent callback.

Adoptable Storage Devices With this release, users can adopt external storage devices such as SD cards. New Icon class that you can attach to your notifications via the setSmallIcon and setLargeIcon methods. Similarly, the addAction method now accepts an Icon object instead of a drawable resource ID.

New getActiveNotifications method that allows your apps to find out which of their notifications are currently alive. Bluetooth Stylus Support This release provides improved support for user input using a Bluetooth stylus.

For apps targeting Android 6. Improved Bluetooth Low Energy Scanning If your app performs performs Bluetooth Low Energy scans, use the new setCallbackType method to specify that you want the system to notify callbacks when it first finds, or sees after a long time, an advertisement packet matching the set ScanFilter.

Hotspot 2. New AudioRecord. Builder and AudioTrack. Builder classes to create digital audio capture and playback objects respectively, and configure audio source and sink properties to override the system defaults. API hooks for associating audio and input devices. This is particularly useful if your app allows users to start a voice search from a game controller or remote control connected to Android TV.

The system invokes the new onSearchRequested callback when the user starts a search. To determine if the user's input device has a built-in microphone, retrieve the InputDevice object from that callback, then call the new hasMicrophone method. New getDevices method which lets you retrieve a list of all audio devices currently connected to the system.

You can also register an AudioDeviceCallback object if you want the system to notify your app when an audio device connects or disconnects.

Video Features This release adds new capabilities to the video processing APIs, including: New MediaSync class which helps applications to synchronously render audio and video streams.

The audio buffers are submitted in non-blocking fashion and are returned via a callback. It also supports dynamic playback rate. If your app uses DRM sessions, you should handle this event and make sure not to use a reclaimed session.

With this exception, the codec must be released, as it has moved to terminal state. New getMaxSupportedInstances interface to get a hint for the max number of the supported concurrent codec instances.

New setPlaybackParams method to set the media playback rate for fast or slow motion playback. It also stretches or speeds up the audio playback automatically in conjunction with the video.

To get an empty buffer, follow this programming model: Call the dequeueInputImage method. Fill the data into the input buffer. Send the buffer to the camera by calling the queueInputImage method. Disable or re-enable the status bar including quick settings, notifications, and the navigation swipe-up gesture that launches Google Now with the setStatusBarDisabled method. You can now provision devices through a Device Owner that fetches and installs apps without user interaction.

This feature is useful for enabling one-touch provisioning of kiosks or other such devices without activating a Google account. Silent enterprise certificate access: When an app calls choosePrivateKeyAlias , prior to the user being prompted to select a certificate, the Profile or Device Owner can now call the onChoosePrivateKeyAlias method to provide the alias silently to the requesting application.

This feature lets you grant managed apps access to certificates without user interaction. Auto-acceptance of system updates. By setting a system update policy with setSystemUpdatePolicy , a Device Owner can now auto-accept a system update, for instance in the case of a kiosk device, or postpone the update and prevent it being taken by the user for up to 30 days. Furthermore, an administrator can set a daily time window in which an update must be taken, for example during the hours when a kiosk device is not in use.

When a system update is available, the system checks if the device policy controller app has set a system update policy, and behaves accordingly. Profile Owners are automatically granted permission to query data on the profile they manage, while Device Owners get access to usage data of the managed primary user.

Overview Android Gradle Plugin The Android Gradle Plugin AGP is the supported build system for Android applications and includes support for compiling many different types of sources and linking them together into an application that you can run on a physical Android device or an emulator.

This library is available in Java , Native code , and Unity. Reference Deprecated Libraries These libraries are superseded by the AndroidX libraries and are no longer maintened. They are still shipped in the SDK to support legacy apps.
