אינטרנציונליזציה
העדפות שפה לכל אפליקציה
Android 14 expands on the per-app language features that were introduced in Android 13 (API level 33) with these additional capabilities:
Automatically generate an app's
localeConfig
: Starting with Android Studio Giraffe Canary 7 and AGP 8.1.0-alpha07, you can configure your app to support per-app language preferences automatically. Based on your project resources, the Android Gradle plugin generates theLocaleConfig
file and adds a reference to it in the final manifest file, so you no longer have to create or update the file manually. AGP uses the resources in theres
folders of your app modules and any library module dependencies to determine the locales to include in theLocaleConfig
file.Dynamic updates for an app's
localeConfig
: Use thesetOverrideLocaleConfig()
andgetOverrideLocaleConfig()
methods inLocaleManager
to dynamically update your app's list of supported languages in the device's system settings. Use this flexibility to customize the list of supported languages per region, run A/B experiments, or provide an updated list of locales if your app utilizes server-side pushes for localization.App language visibility for input method editors (IMEs): IMEs can utilize the
getApplicationLocales()
method to check the language of the current app and match the IME language to that language.
Grammatical Inflection API
3 billion people speak gendered languages: languages where grammatical categories—such as nouns, verbs, adjectives, and prepositions—inflect according to the gender of people and objects you talk to or about. Traditionally, many gendered languages use masculine grammatical gender as the default or generic gender.
Addressing users in the wrong grammatical gender, such as addressing women in masculine grammatical gender, can negatively impact their performance and attitude. In contrast, a UI with language that correctly reflects the user's grammatical gender can improve user engagement and provide a more personalized and natural-sounding user experience.
To help you build a user-centric UI for gendered languages, Android 14 introduces the Grammatical Inflection API, which lets you add support for grammatical gender without refactoring your app.
העדפות אזוריות
Regional preferences enable users to personalize temperature units, the first day of the week, and numbering systems. A European living in the United States might prefer temperature units to be in Celsius rather than Fahrenheit and for apps to treat Monday as the beginning of the week instead of the US default of Sunday.
New Android Settings menus for these preferences provide users with a
discoverable and centralized location to change app preferences. These
preferences also persist through backup and restore. Several APIs and
intents—such as
getTemperatureUnit
and
getFirstDayOfWeek
—
grant your app read access to user preferences, so your app can adjust how it
displays information. You can also register a
BroadcastReceiver
on
ACTION_LOCALE_CHANGED
to handle locale configuration changes when regional preferences change.
To find these settings, open the Settings app and navigate to System > Languages & input > Regional preferences.


נגישות
הגדלת גופן לא לינארית ל-200%
Starting in Android 14, the system supports font scaling up to 200%, providing low-vision users with additional accessibility options that align with Web Content Accessibility Guidelines (WCAG).
To prevent large text elements on screen from scaling too large, the system applies a nonlinear scaling curve. This scaling strategy means that large text doesn't scale at the same rate as smaller text. Nonlinear font scaling helps preserve the proportional hierarchy between elements of different sizes while mitigating issues with linear text scaling at high degrees (such as text being cut off or text that becomes harder to read due to an extremely large display sizes).
Test your app with nonlinear font scaling

If you already use scaled pixels (sp) units to define text sizing, then these additional options and scaling improvements are applied automatically to the text in your app. However, you should still perform UI testing with the maximum font size enabled (200%) to ensure that your app applies the font sizes correctly and can accommodate larger font sizes without impacting usability.
To enable 200% font size, follow these steps:
- Open the Settings app and navigate to Accessibility > Display size and text.
- For the Font size option, tap the plus (+) icon until the maximum font size setting is enabled, as shown in the image that accompanies this section.
Use scaled pixel (sp) units for text-sizes
Remember to always specify text sizes in sp units. When your app uses sp units, Android can apply the user's preferred text size and scale it appropriately.
Don't use sp units for padding or define view heights assuming implicit padding: with nonlinear font scaling sp dimensions might not be proportional, so 4sp + 20sp might not equal 24sp.
Convert scaled pixel (sp) units
Use TypedValue.applyDimension()
to convert from sp units
to pixels, and use TypedValue.deriveDimension()
to
convert pixels to sp. These methods apply the appropriate nonlinear scaling
curve automatically.
Avoid hardcoding equations using
Configuration.fontScale
or
DisplayMetrics.scaledDensity
. Because font scaling is
nonlinear, the scaledDensity
field is no longer accurate. The fontScale
field should be used for informational purposes only because fonts are no longer
scaled with a single scalar value.
Use sp units for lineHeight
Always define android:lineHeight
using sp units instead
of dp, so the line height scales along with your text. Otherwise, if your text
is sp but your lineHeight
is in dp or px, it doesn't scale and looks cramped.
TextView automatically corrects the lineHeight
so that your intended
proportions are preserved, but only if both textSize
and lineHeight
are
defined in sp units.
מצלמה ומדיה
Ultra HDR לתמונות

Android 14 adds support for High Dynamic Range (HDR) images that retain more of the information from the sensor when taking a photo, which enables vibrant colors and greater contrast. Android uses the Ultra HDR format, which is fully backward compatible with JPEG images, allowing apps to seamlessly interoperate with HDR images, displaying them in Standard Dynamic Range (SDR) as needed.
Rendering these images in the UI in HDR is done automatically by the framework
when your app opts in to using HDR UI for its Activity Window, either through a
manifest entry or at runtime by calling
Window.setColorMode()
. You can also capture compressed Ultra
HDR still images on supported devices. With more colors recovered
from the sensor, editing in post can be more flexible. The
Gainmap
associated with Ultra HDR images can be used to render
them using OpenGL or Vulkan.

Android 14 upgrades and improves camera extensions, allowing apps to handle longer processing times, which enables improved images using compute-intensive algorithms like low-light photography on supported devices. These features give users an even more robust experience when using camera extension capabilities. Examples of these improvements include:
- Dynamic still capture processing latency estimation provides much more
accurate still capture latency estimates based on the current scene and
environment conditions. Call
CameraExtensionSession.getRealtimeStillCaptureLatency()
to get aStillCaptureLatency
object that has two latency estimation methods. ThegetCaptureLatency()
method returns the estimated latency betweenonCaptureStarted
andonCaptureProcessStarted()
, and thegetProcessingLatency()
method returns the estimated latency betweenonCaptureProcessStarted()
and the final processed frame being available. - Support for capture progress callbacks so that apps can display the current
progress of long-running, still-capture processing operations. You can check
if this feature is available with
CameraExtensionCharacteristics.isCaptureProcessProgressAvailable
, and if it is, you implement theonCaptureProcessProgressed()
callback, which has the progress (from 0 to 100) passed in as a parameter. Extension specific metadata, such as
CaptureRequest.EXTENSION_STRENGTH
for dialing in the amount of an extension effect, such as the amount of background blur withEXTENSION_BOKEH
.Postview Feature for Still Capture in camera extensions, which provides a less-processed image more quickly than the final image. If an extension has increased processing latency, a postview image could be provided as a placeholder to improve UX and switched out later for the final image. You can check if this feature is available with
CameraExtensionCharacteristics.isPostviewAvailable
. Then you can pass anOutputConfiguration
toExtensionSessionConfiguration.setPostviewOutputConfiguration
.Support for
SurfaceView
allowing for a more optimized and power-efficient preview render path.Support for tap to focus and zoom during extension usage.
זום בתוך החיישן
When REQUEST_AVAILABLE_CAPABILITIES_STREAM_USE_CASE
in
CameraCharacteristics
contains
SCALER_AVAILABLE_STREAM_USE_CASES_CROPPED_RAW
, your app
can use advanced sensor capabilities to give a cropped RAW stream the same
pixels as the full field of view by using a CaptureRequest
with a RAW target that has stream use case set to
CameraMetadata.SCALER_AVAILABLE_STREAM_USE_CASES_CROPPED_RAW
.
By implementing the request override controls, the updated camera gives users
zoom control even before other camera controls are ready.
אודיו ב-USB ללא אובדן נתונים
Android 14 gains support for lossless audio formats for audiophile-level
experiences over USB wired headsets. You can query a USB device for its
preferred mixer attributes, register a listener for changes in preferred mixer
attributes, and configure mixer attributes using the
AudioMixerAttributes
class. This class represents the
format, such as channel mask, sample rate, and behavior of the audio mixer. The
class allows for audio to be sent directly, without mixing,
volume adjustment, or processing effects.

Android 14 adds Credential Manager as a platform API, with additional support back to Android 4.4 (API level 19) devices through a Jetpack Library using Google Play services. Credential Manager aims to make sign-in easier for users with APIs that retrieve and store credentials with user-configured credential providers. Credential Manager supports multiple sign-in methods, including username and password, passkeys, and federated sign-in solutions (such as Sign-in with Google) in a single API.
Passkeys provide many advantages. For example, passkeys are built on industry standards, can work across different operating systems and browser ecosystems, and can be used with both websites and apps.
For more information, see the Credential Manager and passkeys documentation and the blogpost about Credential Manager and passkeys.
Health Connect
Health Connect is an on-device repository for user health and fitness data. It allows users to share data between their favorite apps, with a single place to control what data they want to share with these apps.
On devices running Android versions prior to Android 14, Health Connect is available to download as an app on the Google Play store. Starting with Android 14, Health Connect is part of the platform and receives updates through Google Play system updates without requiring a separate download. With this, Health Connect can be updated frequently, and your apps can rely on Health Connect being available on devices running Android 14 or higher. Users can access Health Connect from the Settings in their device, with privacy controls integrated into the system settings.


Health Connect includes several new features in Android 14, such as exercise routes, allowing users to share a route of their workout which can be visualized on a map. A route is defined as a list of locations saved within a window of time, and your app can insert routes into exercise sessions, tying them together. To ensure that users have complete control over this sensitive data, users must allow sharing individual routes with other apps.
For more information, see the Health Connection documentation and the blogpost on What's new in Android Health.

שיפורים לחנויות אפליקציות
Android 14 introduces several PackageInstaller
APIs that
allow app stores to improve their user experience.
Request install approval before downloading
Installing or updating an app might require user approval.
For example, when an installer making use of the
REQUEST_INSTALL_PACKAGES
permission attempts to install a
new app. In prior Android versions, app stores can only request user approval
after APKs are written to the install session and the
session is committed.
Starting with Android 14, the requestUserPreapproval()
method lets installers request user approval before committing the install
session. This improvement lets an app store defer downloading any APKs until
after the installation has been approved by the user. Furthermore, once a user
has approved installation, the app store can download and install the app in the
background without interrupting the user.
Claim responsibility for future updates
The setRequestUpdateOwnership()
method allows an installer
to indicate to the system that it intends to be responsible for future updates
to an app it is installing. This capability enables update ownership
enforcement, meaning that only the update owner is permitted
to install automatic updates to the app. Update ownership enforcement helps to
ensure that users receive updates only from the expected app store.
Any other installer, including those making use of the
INSTALL_PACKAGES
permission, must receive explicit user
approval in order to install an update. If a user decides to proceed with an
update from another source, update ownership is lost.
Update apps at less-disruptive times
App stores typically want to avoid updating an app that is actively in use because this leads to the app's running processes being killed, which potentially interrupts what the user was doing.
Starting with Android 14, the InstallConstraints
API
gives installers a way to ensure that their app updates happen at an opportune
moment. For example, an app store can call the
commitSessionAfterInstallConstraintsAreMet()
method to
make sure that an update is only committed when the user is no longer
interacting with the app in question.
Seamlessly install optional splits
With split APKs, features of an app can be delivered in separate APK files,
rather than as a monolithic APK. Split APKs allow app stores to optimize the
delivery of different app components. For example, app stores might optimize
based on the properties of the target device. The
PackageInstaller
API has supported splits since its
introduction in API level 22.
In Android 14, the setDontKillApp()
method allows an
installer to indicate that the app's running processes shouldn't be killed when
new splits are installed. App stores can use this feature to seamlessly install
new features of an app while the user is using the app.
חבילות מטא-נתונים של אפליקציות
Starting in Android 14, the Android package installer lets you specify app metadata, such as data safety practices, to include on app store pages such as Google Play.
זיהוי מקרים שבהם משתמשים מצלמים צילומי מסך של המכשיר
To create a more standardized experience for detecting screenshots, Android 14 introduces a privacy-preserving screenshot detection API. This API lets apps register callbacks on a per-activity basis. These callbacks are invoked, and the user is notified, when the user takes a screenshot while that activity is visible.

הוספת פעולות בהתאמה אישית
ב-Android 14, האפליקציה יכולה להוסיף פעולות בהתאמה אישית לגיליון השיתוף של המערכת שהיא מפעילה.

שיפור הדירוג של יעדים לשיתוף ישיר
ב-Android 14 נעשה שימוש באותות רבים יותר מאפליקציות כדי לקבוע את הדירוג של יעדי השיתוף הישיר, וכך לספק תוצאות מועילות יותר למשתמש. כדי לספק את האות הכי שימושי לדירוג, פועלים לפי ההנחיות לשיפור הדירוג של היעדים של שיתוף ישיר. אפליקציות תקשורת יכולות גם לדווח על שימוש במקשי קיצור להודעות יוצאות ונכנסות.

תמיכה באנימציות מובנות ומותאמות אישית עבור 'חזרה חזויה'
Android 13 introduced the predictive back-to-home animation behind a developer option. When used in a supported app with the developer option enabled, swiping back shows an animation indicating that the back gesture exits the app back to the home screen.
Android 14 includes multiple improvements and new guidance for Predictive Back:
- You can set
android:enableOnBackInvokedCallback=true
to opt in to predictive back system animations per-Activity instead of for the entire app. - We've added new system animations to accompany the back-to-home animation from Android 13. The new system animations are cross-activity and cross-task, which you get automatically after migrating to Predictive Back.
- We've added new Material Component animations for Bottom sheets, Side sheets, and Search.
- We've created design guidance for creating custom in-app animations and transitions.
- We've added new APIs to support custom in-app transition animations:
handleOnBackStarted
,handleOnBackProgressed
,handleOnBackCancelled
in
OnBackPressedCallback
onBackStarted
,onBackProgressed
,onBackCancelled
in
OnBackAnimationCallback
- Use
overrideActivityTransition
instead ofoverridePendingTransition
for transitions that respond as the user swipes back.
With this Android 14 preview release, all features of Predictive Back remain behind a developer option. See the developer guide to migrate your app to predictive back, as well as the developer guide to creating custom in-app transitions.

Per-app overrides change the behavior of apps on large screen devices. For example, the OVERRIDE_MIN_ASPECT_RATIO_LARGE
device manufacturer override sets the app aspect ratio to 16:9 regardless of the app's configuration.
Android 14 QPR1 enables users to apply per‑app overrides by means of a new settings menu on large screen devices.
שיתוף מסך של אפליקציה
App screen sharing enables users to share an app window instead of the entire device screen during screen content recording.
With app screen sharing, the status bar, navigation bar, notifications, and other system UI elements are excluded from the shared display. Only the content of the selected app is shared.
App screen sharing improves productivity and privacy by enabling users to run multiple apps but limit content sharing to a single app.

גרפיקה
אפשר לשלוח שאילתות לגבי נתיבים ולבצע בהם אינטרפולציה
ה-API Path
של Android הוא מנגנון עוצמתי וגמיש ליצירה ולרינדור של גרפיקה וקטורית, עם אפשרות לצייר או למלא נתיב, לבנות נתיב מקטעי קו או מעקומות ריבועיות או ממעלה שלישית, לבצע פעולות בוליאניות כדי לקבל צורות מורכבות יותר או את כל האפשרויות האלה בו-זמנית. אחת מהמגבלות היא היכולת לברר מה נמצא בפועל באובייקט Path. הרכיבים הפנימיים של האובייקט לא גלויים למבצעי הקריאה אחרי היצירה.
כדי ליצור Path
, צריך לבצע קריאה ל-methods כמו moveTo()
, lineTo()
ו-cubicTo()
כדי להוסיף קטעי נתיב. אבל לא הייתה אפשרות לשאול את הנתיב הזה מהם הפלחים, ולכן צריך לשמור את המידע הזה בזמן היצירה.
החל מ-Android 14, אפשר לשלוח שאילתות לגבי נתיבים כדי לבדוק מה נמצא בהם.
קודם כול, צריך לקבל אובייקט PathIterator
באמצעות API של Path.getPathIterator
:
Kotlin
val path = Path().apply { moveTo(1.0f, 1.0f) lineTo(2.0f, 2.0f) close() } val pathIterator = path.pathIterator
Java
Path path = new Path(); path.moveTo(1.0F, 1.0F); path.lineTo(2.0F, 2.0F); path.close(); PathIterator pathIterator = path.getPathIterator();
לאחר מכן אפשר לקרוא ל-PathIterator
כדי לבצע איטרציה אחרי הפילוחים אחד אחרי השני, ולאחזר את כל הנתונים הנדרשים לכל פלח. בדוגמה הזו נעשה שימוש באובייקטים מסוג PathIterator.Segment
, שמארזים את הנתונים בשבילכם:
Kotlin
for (segment in pathIterator) { println("segment: ${segment.verb}, ${segment.points}") }
Java
while (pathIterator.hasNext()) { PathIterator.Segment segment = pathIterator.next(); Log.i(LOG_TAG, "segment: " + segment.getVerb() + ", " + segment.getPoints()); }
ב-PathIterator
יש גם גרסה של next()
שלא מקצה לה, שבה אפשר להעביר במאגר נתונים זמני כדי לשמור את נתוני הנקודות.
אחד מהתרחישים החשובים לדוגמה לשליחת שאילתות לגבי נתוני Path
הוא אינטרפולציה. לדוגמה, יכול להיות שתרצו ליצור אנימציה (או טרנספורמציה) בין שני נתיבים שונים. כדי לפשט את התרחיש הזה, Android 14 כולל גם את השיטה interpolate()
ב-Path
. בהנחה שלשני הנתיבים יש מבנה פנימי זהה, ה-method interpolate()
יוצרת Path
חדש עם התוצאה בעלת האינטרפולציה. הדוגמה הזו מחזירה נתיב שהצורה שלו היא חצי (אינטרפולציה לינארית של 0 .5) בין path
ל-otherPath
:
Kotlin
val interpolatedResult = Path() if (path.isInterpolatable(otherPath)) { path.interpolate(otherPath, .5f, interpolatedResult) }
Java
Path interpolatedResult = new Path(); if (path.isInterpolatable(otherPath)) { path.interpolate(otherPath, 0.5F, interpolatedResult); }
ספריית graphics-path של Jetpack מאפשרת להשתמש בממשקי API דומים גם בגרסאות קודמות של Android.

Android has long supported drawing triangle meshes with custom shading, but the input mesh format has been limited to a few predefined attribute combinations. Android 14 adds support for custom meshes, which can be defined as triangles or triangle strips, and can, optionally, be indexed. These meshes are specified with custom attributes, vertex strides, varying, and vertex and fragment shaders written in AGSL.
The vertex shader defines the varyings, such as position and color, while the
fragment shader can optionally define the color for the pixel, typically by
using the varyings created by the vertex shader. If color is provided by the
fragment shader, it is then blended with the current Paint
color using the blend mode selected when
drawing the mesh. Uniforms can be passed
into the fragment and vertex shaders for additional flexibility.
