Core-Backported-Fixes Version 1.0

Version 1.0.0-beta01

September 24, 2025

androidx.core:core-backported-fixes:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

Version 1.0.0-alpha01

August 13, 2025

androidx.core:core-backported-fixes:1.0.0-alpha01 is released. Version 1.0.0-alpha01 contains these commits.

New Features

The Core Backported Fixes library lets you check if a critical bug fix has been applied to a device. This is useful because it can take a long time for bug fixes to be rolled out to all devices, and this API provides a way for you to know when it is safe to use features that depend on a fix.
```
val fixManager = BackportedFixManager()
    if (fixManager.isFixed(KnownIssues.KI_1234)) {
      Offer_experience_that_needs_fix()
    } else {
      Offer_experience_that_avoids_the_bug()
  }
```

This release includes

KnownIssues.KI_398591036: Abnormal color tone when capturing JPEG-R images on some Pixel devices. Fix by using JPEG outputs until this KI is resolved.

Core-Viewtree Version 1.0

Version 1.0.0

February 26, 2025

androidx.core:core-viewtree:1.0.0 has been promoted to its first stable release with no changes since its previous RC version.

This library introduces the concept of a View being able to have a disjoint parent. A disjoint parent of a view is a separate View object that acts as the view’s parent, but is not set via the View.parent property. Examples of Views with disjoint parents are ViewOverlays, popups, and dialogs, which all appear outside of the main view hierarchy. A View can only have a disjoint parent if it does not have a direct parent via the platform’s View.parent property. Currently, androidx only sets the disjoint parent for ViewOverlays created by Transition 1.6.0-alpha01 and higher. You can also specify your own disjoint parents for views. See the documentation for more information.

Version 1.0.0-rc01

February 12, 2025

androidx.core:core-viewtree:1.0.0-rc01 is released with no changes since the beta.

Version 1.0.0-beta01

January 29, 2025

Version 1.0.0-alpha01

December 11, 2024

androidx.core:core-viewtree:1.0.0-alpha01 is released. Version 1.0.0-alpha01 contains these commits.

New Features

Initial release of core-viewtree, transitively exposed by androidx core.
This initial release introduces the concept of a View being able to have a disjoint parent. A disjoint parent of a view is a separate View object that acts as the view’s parent, but is not set via the View.parent property. Examples of Views with disjoint parents are ViewOverlays, popups, and dialogs, which all appear outside of the main view hierarchy. A View can only have a disjoint parent if it does not have a direct parent via the platform’s View.parent property. Currently, androidx only sets the disjoint parent for ViewOverlays created by transition. You can also specify your own disjoint parents for views. See the documentation for more information.

API Changes

Adds ViewParent.getParentOrViewTreeDisjointParent() and ViewParent.setViewTreeDisjointParent(View, ViewParent?) methods (Ib2950)

Core-i18n Version 1.0

Version 1.0.0

April 9, 2025

androidx.core:core-i18n:1.0.0 is released.

The component makes it easier to create properly internationalized applications, focusing on two main areas:

Date and time formatting functionality following the best current practices, honoring user custom settings, and providing a unifying API that works properly on old and new Android versions.
A backport of android.icu.text.MessageFormat that works on older APIs. But still useful on new Android versions because it integrates the date / time formatting mentioned above. That honors the user settings, which android.icu.text.MessageFormat does not do.

The component will be the vehicle to backporting new i18n APIs, adding new i18n functionality or fixes, and in general making internationalization easier.

Version 1.0.0-rc01

March 26, 2025

androidx.core:core-i18n:1.0.0-rc01 is released with no notable changes since the last beta. Version 1.0.0-rc01 contains these commits.

Version 1.0.0-beta01

March 12, 2025

androidx.core:core-i18n:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

Security fix

As of this change, androidx compiles against protobuf 4.28.2 in order to address CVE-2024-7254. Upgrade your dependency on androidx.core:core-location-altitude-protoand androidx.core:core-location-altitude-external-protobuf to 1.1.0-alpha03 to address the vulnerability risk.

Bug Fixes

Removed manual outlining of access to new platform APIs since this happens automatically via API modeling when using R8 with AGP 7.3 or later (e.g. R8 version 3.3) and for all builds when using AGP 8.1 or later (e.g. D8 version 8.1). Clients who are not using AGP are advised to update to D8 version 8.1 or later. See this article for more details. (Ieb9ae, b/345472586)

Version 1.0.0-alpha02

June 12, 2024

Version 1.0.0-alpha01

July 26, 2023

androidx.core:core-i18n:1.0.0-alpha01 and androidx.core:core-location-altitude:1.0.0-alpha01 are released. Version 1.0.0-alpha01 contains these commits.

New Features

Added AltitudeConverterCompat class with a single static method addMslAltitudeToLocation(Context, Location) (I11168).

Core-telecom Version 1.1

Version 1.1.0-alpha01

October 8th, 2025

androidx.core:core-telecom:1.1.0-alpha01 is released. Version 1.1.0-alpha01 contains these commits.

New Features

Added the ability for applications to request that a specific call not be saved in the system call log, even if the app has generally opted into call logging. This feature is only effective on devices running Build.VERSION.SDK_INT_FULL >= Build.VERSION_CODES_FULL.BAKLAVA_1.

API Changes

Introduced the optional isLogExcluded Boolean property to the CallAttributesCompat data class. Setting this to true requests the system to exclude the call from the call log. On older platform versions, this property has no effect. Please note that VoIP calls are not logged to the system call log by default. Developers must first explicitly opt-in their application to participate in system call logging. This requires declaring an intent handler for android.telecom.action.CALL_BACK in the app's manifest. The new isLogExcluded property provides a per-call exclusion option for apps that have already enabled this integration. (d14695)

Core-telecom Version 1.0.

Version 1.0.1

August 27, 2025

androidx.core:core-telecom:1.0.1 is released. Version 1.0.1 is a bug-fix release that includes the following improvements which can be found in the these commits.

Bug Fixes

Audio Routing and Endpoint Handling
- Resolved an issue where a user's selected pre-call audio endpoint (e.g., Earpiece) would be incorrectly switched to Speaker when a video call starts. The library now ensures the user's preferred audio route is maintained. (8fa4ba7, 71d7be8)
- Improved the audio switching logic to prevent calls from automatically switching from Bluetooth headset to Speaker, especially when the Bluetooth device takes a moment to connect. This check requires the BLUETOOTH_CONNECT permission to differentiate between device types.(de83f3e)
- Optimized the auto-speaker functionality for video calls for users without Bluetooth devices. The library now performs a less intrusive check for Bluetooth devices before requesting the BLUETOOTH_CONNECT permission, improving the experience for non-Bluetooth users. (721f4e2)
Stability and Crash Fixes
- Fixed NullPointerException crashes that could occur during audio endpoint processing. The library now correctly handles inconsistent state management in PreCallEndpointsUpdater and filters null elements from the system's AudioDeviceInfo array to improve stability. (23dd075, 03eb616)

Version 1.0.0

May 7, 2025

androidx.core:core-telecom:1.0.0 is released. Version 1.0.0 contains these commits.

Major features of 1.0.0

Initial stable release of core-telecom API, focusing on CallsManager API surface for integration of VoIP calls into the Android platform.

Version 1.0.0-rc01

April 9, 2025

androidx.core:core-telecom:1.0.0-rc01 is released. Version 1.0.0-rc01 contains these commits.

New Features

New experimental API call extensions. The new experimental extensions added in this release are:

Support for a Meeting Summary Remote Extension, allowing a remote surface to receive meeting summary information (current speaker and participant count) from the connected VoIP application. (7cf095f)
Support for a Call Icon Extension that allows a VoIP app to send an Icon Uri to a remote InCallService (auto, watch face, etc.). The Icon can be updated throughout the call and can have the same URI value. (8e1813e)

Version 1.0.0-beta01

December 11, 2024

androidx.core:core-telecom:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

New Features

Beta release for the following new features:

Fetching available audio endpoints before a call is added. App developers can now display all the available endpoints before initiating a call which allows users to seamlessly select their preferred audio endpoint and optimize their setup. This eliminates the need for in-call adjustments at the start of the call, providing a smoother experience.
Experimental API support for VOIP application call extensions. Call extensions allow an application to provide more details about an ongoing call, such as the list of participants in a group call or meeting. Supported remote surfaces such as Android Auto can then show this information to the user and allow them to interact with the supported extensions. The new experimental extensions added in this release are:
- Support for showing the participants in a group call or meeting and describing which participant is active. Support for the following optional actions on participants:
  - Raising and lowering the hands of participants.
  - Kicking participants.
- Support for call silence, which allows remote surfaces to silence a VOIP call without also globally muting the mic.

API Changes

Rename addLocalSilenceExtension to addLocalCallsilenceExtension (If4a9c)
Change preferredStartingCallEndpointfrom var to val. (Iab6b7)
Add local call silence APIs (I29dd0)
Implement the compareTo function for the CallEndpointCompat class (Ia06b7)
Adds experimental app actions API. (Ifb796)
Add new CallsManager API getAvailableStartingCallEndpoints (Ia8bcf)
Update ExperimentalAppActions annotation to ensure that it is accurately tracking all usages of the experimental feature. (Id5ea5)

Bug Fixes

Add global mute state receiver for Android API level 28 through 33. (I75e66)
Fixes an issue where only the latest connected InCallService would be able to send action events (I39599)
Implements ICS Extensions API for voip app actions. (I1274c)
Rejecting a call before API level 34 will now correctly destroy the call in Telecom. (I635b7)
addCall now properly throws Exceptions through the API instead of the parent coroutine (I83334)
Add a placeholder value to extras bundle (Iebf7f)
Removed manual outlining of access to new platform APIs since this happens automatically via API modeling when using R8 with AGP 7.3 or later (e.g. R8 version 3.3) and for all builds when using AGP 8.1 or later (e.g. D8 version 8.1). Clients who are not using AGP are advised to update to D8 version 8.1 or later. See this article for more details. (Ieb9ae, b/345472586)
Adds experimental support for extensions to CallsManager#addCall. (I24d92)
Core-Telecom will now throw a CallException if the platform failed to add the call due to an exception, reaching max call count, etc. (I41f27)

Version 1.0.0-alpha03

Version 1.0.0-alpha02

October 4, 2023

androidx.core:core-telecom:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

API Changes

Revamped the API signatures for methods that returned boolean to indicate success/failure to instead return a result class that clearly indicates why an operation succeeded or failed.
Moved the CallControlCallback methods as lambda args to addCall to remove the need to explicitly provide a callback in the call scope.

Bug Fixes

Fixed a bug in the ConnectionService compatibility layer which would have resulted in no call audio when running against pre-U SDKs.
Improve API documentation.

Version 1.0.0-alpha01

May 10, 2023

androidx.core:core-telecom:1.0.0-alpha01 is released. This version is developed in an internal branch and should be used with Android 14 Beta 2.

New Features

Introduces the CallsManager API which VoIP apps can use for integrating with the Telecom framework on a device. Calls notified to the platform benefit from foreground execution priority, visibility on Bluetooth, wearable and automotive devices, and simplified audio routing.

Important Changes since 1.0.0

Updated accessibility APIs to match the Android 10 platform accessibility APIs
Added improvements to Nested Scrolling; see NestedScrollingChild3 and NestedScrollingParent3.
This library no longer exposes the androidx.collection dependency as part of its API. If you were depending on the androidx.collection types implicitly through a dependency on Core, you will need to add an explicit androidx.collection dependency to your library or app. This change is source-incompatible but retains binary compatibility. The Collection dependency is still a transitive dependency of Core but as an implementation detail instead of part of its API.

Added a variety of fixes for AppCompat DayNight (aosp/942956)

The initial release of AndroidX broke backwards compatibility for Support Library compat APIs that are used for inter-process communication, sending keyed data in bundles. This release fixes this compatibility, restoring communication between code built with Support Library 28.0 (or earlier) and AndroidX 1.1 (or later).

API changes

Undeprecated capability setters (aosp/937281)
RemoteActionCompat is now a 1VersionedParcelable` (aosp/928534)

Version 1.1.0-alpha05

March 13, 2019

androidx.core:core:1.1.0-alpha05 and androidx.core:core-ktx:1.1.0-alpha05 are released. The full list of commits included in this version can be found here.

New features

New ActivityCompat.recreate() API for working around pre-28 platform bugs (aosp/898940)
New LocationManagerCompat class (aosp/894736)

API changes

This library no longer exposes the ‘collection’ dependency as part of its API. If you were depending on the ‘collection’ types implicitly through a dependency on ‘core’, you will need to add an explicit ‘collection’ dependency to your library or app. This change is source-incompatible but retains binary compatibility. The ‘collection’ dependency is still a transitive dependency of ‘core’ but as an implementation detail instead of part of its API.

Bug fixes

Fixed bug with default tint mode for ImageView on devices running API level 21

Version 1.1.0-alpha04

January 30, 2019

Fixed bug where replacing accessibility actions, and adding accessibility actions, didn't remove old accessibility actions (aosp/848314)

Version 1.1.0-alpha03

December 17, 2018

API changes

Added new APIs to ShortcutManagerCompat to publish and update dynamic shortcuts.

Version 1.1.0-alpha01

November 5, 2018

androidx.core 1.1.0-alpha01 is released with the following API changes and bug fixes.

New features and API changes

NestedScrollingChild3 and NestedScrollingParent3 add the ‘consumed’ parameter to the overloaded dispatchNestedScroll and * onNestedScroll methods so that the view that drives nested scrolling can be better informed about how much scroll distance was * consumed by parents in each nested scroll pass.
NestedScrollView now implements NestedScrollingChild3 and NestedScrollingParent3, and therefore, the NestedScrollingChild2 and * NestedScrollingParent2 implementations of dispatchNestedScroll and onNestedScroll are not guaranteed to be called. Developers * counting on either being called should also override the new nested scrolling 3 version of dispatchNestedScroll and onNestedScroll.
ShortcutInfoCompat has the following new fields: Persons, categories and isLongLived. Done to advertise it can accept various types * of content.
Renamed SupportActivity to ComponentActivity. See androidx.activity for more info.
Added getMainExecutor() method, which returns an Executor link that will run enqueued tasks on the main thread associated with that * context.
Added compatibility implementation of Resources.getFloat.
Added Results Source to compat RemoteInput. This allows apps to distinguish direct and smart replies for logging purposes.
Added Kotlin extension functions for TextView TextWatcher actions.
Deprecated AccessibilityNodeInfo capability and flag setters; use actions instead.
Added AccessibilityPane to ViewCompat.
Exposed ClickableSpans on pre-O devices through the addition of AccessibilityClickableSpanCompat.
Deprecated AccessibilityNodeInfoCompat.setFocusable(), setClickable(), setLongClickable(), setScrollable(), and setContextClickable(). Added AccessibilityActions instead.
Added ViewCompat.setAccessibilityPaneTitle(), getAccessibilityPaneTitle(), setScreenReaderFocusable(), isScreenReaderFocusable(), setAccessibilityHeading(), and isAccessibilityHeading(), to backport this View accessibility functionality through API 19.
Added ViewCompat.enableAccessibleClickableSpanSupport() to allow developers to make non-URL ClickableSpans accessible back through API 19.

Bug fixes

Fixed bug that caused ResourcesCompat.getFont() crash when the network fails, when using downloadable fonts.
Fixed Null Pointer Exception in TypefaceCompatApi21 that occurred when ContentResolver returned null.
Fixed type error in Array Utils where it expected ColorStateList but got raw colors.
