-lint
artifact provides a Lint-based implementation of experimental usage restrictions and enforces restrictions on Java usages of Kotlin’s native experimental API markers.When using the
annotation-experimental
artifact as a dependency, the Lint rules provided by theannotation-experimental-lint
artifact will be enforced automatically.

Version 1.1.0-beta01
April 3rd, 2019
androidx.annotation:annotation:1.1.0-beta01
is released. The commits included in this version can be found here.
New features
- New
@InspectableProperty
annotation to support the new view inspection APIs added in Android 10. This annotation can be applied to getters on views or other UI elements. Code generation tools may use it to create companion objects that map property names and attribute IDs to property values without the overhead of reflection.
API changes
- Breaking change:
@ContentView
has been changed to a constructor annotation and the@LayoutRes
value has been removed. Classes wishing to support@ContentView
annotations should add this annotation to a constructor that takes a@LayoutRes int
parameter. This fixes an issue when using this annotation in library modules. (b/128352521)

New features
- New API restriction scope:
RestrictTo.Scope.LIBRARY_GROUP_PREFIX
. It restricts usage to code within packages whose groups share the same library group prefix up to the last.
(period). For example, because librariesfoo.bar:lib1
andfoo.baz:lib2
share the prefixfoo
, they can use each other's APIs that are restricted to this scope. Similarly, forcom.foo.bar:lib1
andcom.foo.baz:lib2
share thecom.foo.
prefix and can share APIs restricted to that scope. Librarycom.bar.qux:lib3
however will not be able to use the restricted API because it only shares the prefixcom.
and not all the way until the last.

Bug fixes
- Correct the R8/ProGuard rules which are embedded in the jar. These were incorrectly referencing the old
android.support.annotation
types instead ofandroidx.annotation
. Note: This would have only had an impact on your builds if you were not usinggetDefaultProguardFile
as those default rules also included correct rules for both packages. (aosp/891685) - Add a R8/ProGuard rule which explicitly keeps the @Keep annotation itself. This ensures that ProGuard does not remove the annotation from types prior to actually honoring its semantics. Note: This would have only had an impact on your builds if you were not using
getDefaultProguardFile
as those default rules also included correct rules for both packages. (aosp/903818)
