We’re trying ahead to listening to what you assume, and thanks upfront in your continued help make Android a platform that works for everybody.
Media and digicam updates
Android 16 enhances help for skilled digicam customers, permitting for hybrid auto publicity together with exact shade temperature and tint changes. It is simpler than ever to seize movement pictures with new Intent actions, and we’re persevering with to enhance UltraHDR photos, with help for HEIC encoding and new parameters from the ISO 21496-1 draft customary.
Hybrid auto-exposure
Android 16 provides new hybrid auto-exposure modes to Camera2, permitting you to manually management particular points of publicity whereas letting the auto-exposure (AE) algorithm deal with the remainder. You may management ISO + AE, and publicity time + AE, offering better flexibility in comparison with the present method the place you both have full handbook management or rely completely on auto-exposure.
enjoyable setISOPriority() { // ... val availablePriorityModes = mStaticInfo.traits.get( CameraCharacteristics.CONTROL_AE_AVAILABLE_PRIORITY_MODES ) // ... // Activate AE mode to set precedence mode reqBuilder[CaptureRequest.CONTROL_AE_MODE] = CameraMetadata.CONTROL_AE_MODE_ON reqBuilder[CaptureRequest.CONTROL_AE_PRIORITY_MODE] = CameraMetadata.CONTROL_AE_PRIORITY_MODE_SENSOR_SENSITIVITY_PRIORITY reqBuilder[CaptureRequest.SENSOR_SENSITIVITY] = TEST_SENSITIVITY_VALUE val request: CaptureRequest = reqBuilder.construct() // ... }
Exact shade temperature and tint changes
Android 16 provides digicam help for advantageous shade temperature and tint changes to higher help skilled video recording functions. White stability settings are presently managed via CONTROL_AWB_MODE, which accommodates choices restricted to a preset checklist, similar to Incandescent, Cloudy, and Twilight. The COLOR_CORRECTION_MODE_CCT allows using COLOR_CORRECTION_COLOR_TEMPERATURE and COLOR_CORRECTION_COLOR_TINT for exact changes of white stability primarily based on the correlated shade temperature.
enjoyable setCCT() { // ... (Your present code earlier than this level) ... val colorTemperatureRange: Vary<Int> = mStaticInfo.traits[CameraCharacteristics.COLOR_CORRECTION_COLOR_TEMPERATURE_RANGE] // Set to handbook mode to allow CCT mode reqBuilder[CaptureRequest.CONTROL_AWB_MODE] = CameraMetadata.CONTROL_AWB_MODE_OFF reqBuilder[CaptureRequest.COLOR_CORRECTION_MODE] = CameraMetadata.COLOR_CORRECTION_MODE_CCT reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TEMPERATURE] = 5000 reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TINT] = 30 val request: CaptureRequest = reqBuilder.construct() // ... (Your present code after this level) ... }
Movement photograph seize intent actions
Android 16 provides customary Intent actions — ACTION_MOTION_PHOTO_CAPTURE, and ACTION_MOTION_PHOTO_CAPTURE_SECURE — which request that the digicam software seize a movement photograph and return it.
You will need to both go an additional EXTRA_OUTPUT to manage the place the picture can be written, or a Uri via Intent setClipData. In the event you do not set a ClipData, will probably be copied there for you when calling Context.startActivity.
UltraHDR picture enhancements
Android 16 continues our work to ship dazzling picture high quality with UltraHDR photos. It provides help for UltraHDR photos within the HEIC file format. These photos will get ImageFormat kind HEIC_ULTRAHDR and can include an embedded gainmap much like the prevailing UltraHDR JPEG format. We’re engaged on AVIF help for UltraHDR as nicely, so keep tuned.
As well as, Android 16 implements extra parameters in UltraHDR from the ISO 21496-1 draft customary, together with the power to get and set the colorspace that gainmap math ought to be utilized in, in addition to help for HDR encoded base photos with SDR gainmaps.
Customized graphical results with AGSL
Android 16 provides RuntimeColorFilter and RuntimeXfermode, permitting you to writer advanced results like Threshold, Sepia, and Hue Saturation and apply them to attract calls. Since Android 13, you have been ready to make use of AGSL to create customized RuntimeShaders that stretch Shaders. The brand new API mirrors this, including an AGSL-powered RuntimeColorFilter that extends ColorFilters, and a Xfermode impact that means that you can implement AGSL-based customized compositing and mixing between supply and vacation spot pixels.
personal val thresholdEffectString = """ uniform half threshold; half4 primary(half4 c) { half luminosity = dot(c.rgb, half3(0.2126, 0.7152, 0.0722)); half bw = step(threshold, luminosity); return bw.xxx1 * c.a; }""" enjoyable setCustomColorFilter(paint: Paint) { val filter = RuntimeColorFilter(thresholdEffectString) filter.setFloatUniform(0.5) paint.colorFilter = filter }
Habits modifications
With each Android launch, we search to make the platform extra environment friendly, privateness aware, internationalization pleasant, and strong, balancing the wants of apps in opposition to {hardware} help, system efficiency, person privateness, and battery life.

Well being and health permissions
For apps focusing on Android 16 or larger, BODY_SENSORS permissions are transitioning to the granular permissions underneath android.permissions.well being additionally utilized by Well being Join. Any API beforehand requiring BODY_SENSORS or BODY_SENSORS_BACKGROUND will now require the corresponding android.permissions.well being permission. This impacts the next knowledge varieties, APIs, and foreground service varieties:
In case your app makes use of these APIs, it ought to now request the respective granular permissions:
These permissions are the identical as those who guard entry to studying knowledge from Well being Join, the Android datastore for well being, health, and wellness knowledge.
Deserted empty jobs cease motive
An deserted job happens when the JobParameters object related to the job has been rubbish collected, however jobFinished has not been known as to sign job completion. This means that the job could also be operating and being rescheduled with out the applying’s consciousness.
Functions in Android 16 that depend on JobScheduler with out sustaining a powerful reference to the JobParameters object will now be granted the brand new job cease motive STOP_REASON_TIMEOUT_ABANDONED on timeout, as a substitute of STOP_REASON_TIMEOUT.
If there are frequent occurrences of the brand new deserted cease motive, the system will take mitigation steps to scale back job frequency. Please use the brand new cease motive to detect and scale back deserted jobs.
Observe: In the event you’re utilizing WorkManager, you are not anticipated to be impacted by this alteration — one good facet impact of utilizing Android Jetpack to schedule your work.
Intent redirect modifications
Android 16 introduces default safety hardening in opposition to Intent redirection assaults no matter your app’s targetSDK model. The removeLaunchSecurityProtection API means that you can opt-out of this safety in case your testing reveals points.
Observe: Opting out of safety protections ought to be performed with warning and solely when completely needed, as it could possibly improve the chance of safety vulnerabilities.
val iSublevel = intent.getParcelableExtra("sub_intent", Intent::class.java) iSublevel?.let { it.removeLaunchSecurityProtection() startActivity(it) }
Elegant font APIs deprecated and disabled
Apps focusing on Android 15 (API degree 35) have the elegantTextHeight TextView attribute set to true by default, changing the compact font with one that’s way more readable. You might override this by setting the elegantTextHeight attribute to false.
Android 16 deprecates the elegantTextHeight attribute, and the attribute can be ignored as soon as your app targets Android 16. The “UI fonts” managed by these APIs are being discontinued, so you must adapt any layouts to make sure constant and future proof textual content rendering in Arabic, Lao, Myanmar, Tamil, Gujarati, Kannada, Malayalam, Odia, Telugu or Thai.
16 KB web page measurement compatibility mode
Android 15 launched help for 16KB reminiscence pages to optimize efficiency of the platform. Android 16 provides a compatibility mode, permitting some apps constructed for 4K reminiscence pages to run on a tool configured for 16KB reminiscence pages.

The person choice is included as a part of the locale code, so you may register a BroadcastReceiver on ACTION_LOCALE_CHANGED to deal with locale configuration modifications when regional preferences change.
Utilizing formatters may also help match the native expertise. For instance, “0.5 in” in English (United States), is “12,7 mm” for a person who has set their telephone to English (Denmark) or who makes use of their telephone in English (United States) with the metric system because the measurement system choice.
To search out these settings in Android 16 Beta 2, open the Settings app and navigate to System > Languages & area.
Content material dealing with for dwell wallpapers
In Android 16, the dwell wallpaper framework is gaining a brand new content material API to deal with the challenges of dynamic, user-driven wallpapers. At the moment, dwell wallpapers incorporating user-provided content material require advanced, service-specific implementations. Android 16 introduces WallpaperDescription and WallpaperInstance. WallpaperDescription means that you can establish distinct situations of a dwell wallpaper from the identical service. For instance, a wallpaper that has situations on each the house display and on the lock display could have distinctive content material in each locations. The wallpaper picker and WallpaperManager use this metadata to higher current wallpapers to customers, streamlining the method so that you can create various and customized dwell wallpaper experiences.
Headroom APIs in ADPF

Standardized image and audio high quality framework for TVs
The brand new MediaQuality package deal in Android 16 exposes a set of standardized APIs for entry to audio and movie profiles and hardware-related settings. This permits streaming apps to question profiles and apply them to media dynamically:
- Motion pictures mastered with a wider dynamic vary require better shade accuracy to see refined particulars in shadows and modify to ambient mild, so a profile that prefers shade accuracy over brightness could also be applicable.
- Stay sporting occasions are sometimes mastered with a slim dynamic vary, however are sometimes watched in daylight, so a profile that provides choice to brightness over shade accuracy can provide higher outcomes.
- Absolutely interactive content material needs minimal processing to scale back latency, and desires larger body charges, which is why many TV’s ship with a sport profile.
The API permits apps to change between profiles and customers to take pleasure in the advantages of tuning supported TVs to greatest swimsuit their content material.
Accessibility
Android 16 provides extra APIs to boost UI semantics that assist enhance consistency for customers that depend on accessibility providers, similar to TalkBack.
Period added to TtsSpan
Android 16 extends TtsSpan with a TYPE_DURATION, consisting of ARG_HOURS, ARG_MINUTES, and ARG_SECONDS. This lets you straight annotate time length, making certain correct and constant text-to-speech output with providers like TalkBack.
Assist components with a number of labels
Android presently permits UI components to derive their accessibility label from one other, and now gives the power for a number of labels to be related, a standard situation in internet content material. By introducing a list-based API inside AccessibilityNodeInfo, Android can straight help these multi-label relationships. As a part of this alteration, we have deprecated AccessibilityNodeInfo setLabeledBy and getLabeledBy in favor of addLabeledBy, removeLabeledBy, and getLabeledByList.
Improved help for expandable components
Android 16 provides accessibility APIs that can help you convey the expanded or collapsed state of interactive components, similar to menus and expandable lists. By setting the expanded state utilizing setExpandedState and dispatching TYPE_WINDOW_CONTENT_CHANGED AccessibilityEvents with a CONTENT_CHANGE_TYPE_EXPANDED content material change kind, you may be certain that display readers like TalkBack announce state modifications, offering a extra intuitive and inclusive person expertise.
Indeterminate ProgressBars
Android 16 provides RANGE_TYPE_INDETERMINATE, giving a manner so that you can expose RangeInfo for each determinate and indeterminate ProgressBar widgets, permitting providers like TalkBack to extra persistently present suggestions for progress indicators.
Tri-state CheckBox
The brand new AccessibilityNodeInfo getChecked and setChecked(int) strategies in Android 16 now help a “partially checked” state along with “checked” and “unchecked.” This replaces the deprecated boolean isChecked and setChecked(boolean).
