What’s New in Dagger

Bug fixes

  • Fixed an issue where in rare cases subcomponent builder bindings might accidentally attach to the wrong parent (c2d097f)
  • Build performance improvements (47123ec, 1caa7f0, e2f2b2d)

What’s New in Hilt

Hilt has a new flag, -Adagger.hilt.shareTestComponents, that enables tests with no test-specific bindings (e.g. @BindValue fields or @InstallIn modules within the test class) to share the same generated component. This flag should help improve build times by avoiding generating duplicate components for tests with the same bindings (faebc3c).

Note: This flag is currently disabled by default, but will be enabled by default in a future release of Hilt. For more information on how to enable this flag as well as some caveats, see the docs

New breaking changes

The alpha androidx extension @ViewModelInject is no longer supported. @ViewModelInject has been deprecated since androidx.hilt 1.0.0-alpha03 and was removed in androidx.hilt 1.0.0-beta01. Hilt now falls back to the base activity/fragment default ViewModelProviderFactory (3778ee2)

Migration steps:

Users of @ViewModelInject can migrate to @HiltViewModel which was added in Dagger 2.31.

  1. Add @HiltViewModel annotation to the class
  2. Replace the @ViewModelInject annotation on the constructor with @Inject.
  3. Remove @Assisted from the SavedStateHandle constructor parameter, if it exists
  4. Remove the old androidx.hilt:hilt-lifecycle-viewmodel dependency from your build.gradle file

Bug fixes

  • Update the androidx fragment, lifecycle and activity dependencies which contain patch fixes. (efcdbe1, 57255db)
  • Fix #2511: updates the kotlinx-metadata dependency. (b42731b)
  • Fix issue with proguard removing entry points by adding proguard keep rules. (96171b0)
  • Fix #2456: Rename init() method in generated Activity to avoid conflict with user method of same name. (1c66033)
  • Reduce the possibility of KAPT logging warnings due to no processor supporting disableAndroidSuperclassValidation when no Android entry points are in the source module. (c70cf2d)
  • Fix #2070: Clears the Fragment reference in FragmentContextWrapper after Fragment#onDestroy() to prevent leaks if a non-Hilt View outlives the Hilt Fragment that created it. (7f4c3a2)
