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.

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.

  • Fix incorrect velocity while flinging with nested scrolling. (aosp/961642)
  • Add test for mutating TransitionDrawable (b/37033322)

Version 1.1.0-beta01

May 7, 2019

androidx.core:core:1.1.0-beta01 and androidx.core:core-ktx:1.1.0-beta01 are released. The commits included in this version can be found here.

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)

Bug fixes

  • AppCompatTextView in core tests should be created with an appcompat theme (aosp/951636)
  • Use pre-1.0 string values for InputConnectionCompat (aosp/948725)
  • Use pre-AndroidX strings as fallback interop for bundle keys (aosp/938269)
  • Fixed bug in DayNight updates when in background (aosp/942956)
  • Implemented text entry key API for accessibility services in AOSP Keyboard (aosp/943897)
  • Fixed exception when loading font on devices running API Level 20 and lower
  • Handle disabled <activity-alias> components in NavUtils (aosp/940788)

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

androidx.core:core 1.1.0-alpha04 and androidx.core:core-ktx 1.1.0-alpha04 are released.

API changes

  • Change value of EXTRA_SHORTCUT_ID to be consistent with the platform (aosp/877712)
  • Add CATEGORY_NOTIFICATION to NotificationCompat (aosp/861067)

Bug fixes

  • Fix for fontFamily not working on devices running API level 24 and lower (aosp/807054)
  • 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

androidx.core 1.1.0-alpha03 and androidx.core-ktx 1.1.0-alpha03 are released with the following changes. androidx.core-ktx 1.1.0-alpha02 is released to provide a ktx match for androidx.core 1.1.0-alpha02.

New features

  • Added Notification channels methods to NotificationManagerCompat so developers can use only NotificationManagerCompat when working with notifications. Special thanks to Zdeněk Kořán for this new feature!

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.
