Toothpick v3.0.0-RC1 Release Notes

Release Date: 2019-07-29 // over 2 years ago
    • TP3 specs can be find at
    • KTP specs can be found at Thx to @chenthorne and @dpreussler for their contributions to the Kotlin extensions of TP.
    • Scope annotations are not backward compatible with version 2. In version 2, scope annotations had 2 meaning: @ActivitySingleton meant both that a class could only be injected in a scope that supported this annotation and that the class would provide singletons of this scope. In TP 3, it is now more fine grained: @ActivityScope means a class can only be injected in a scope that supports this annotation and it can be combined with @Singleton or not to denote that a class produces singletons of this scope or not.
    • The scope API is now a fluent API. It is possible to define all scopes and sub scope in the same method chain, and to configure them at the same time. See the new samples. and
    • Kotlin is now a first class citizen of TP 3. KTP supports both field and constructor injection. Extensions are published to make things even more kotlin friendly. KTP doesn't offer method injections. KTP and TP are compatible. You can migrate classes to Kotlin incrementally in a java app using TP3.
    • Support for releasable singletons. TP can release @Releasable annotated singletons under memory pressure to save memory.
    • TP (java) supports method injections for methods throwing exceptions
    • Support for package-protected classes
    • Extension package for AndroidX life cycle allow to close a scope automatically when a FragmentActivity is closed. See sample.
    • Extension package for AndroidX view models allow to inject a view model and get things injected in a view model automatically. See sample.
    • The binding API now is absolutely equivalent to the expressivity of the annotations. The 2 are strictly compatible.
