Dagger

Dagger 2 is a compile-time evolution approach to dependency injection. Taking the approach started in Dagger 1.x to its ultimate conclusion, Dagger 2.0 eliminates all reflection, and improves code clarity by removing the traditional ObjectGraph/Injector in favor of user-specified @Component interfaces.

This github project represents the Dagger 2 development stream. The earlier project page (Square, Inc’s repository) represents the earlier 1.0 development stream.
Both versions have benefitted from strong involvement from Square, Google, and other contributors.

Butter Knife

Field and method binding for Android views which uses annotation processing to generate boilerplate code for you.

  • Eliminate findViewById calls by using @Bind on fields.
  • Group multiple views in a list or array. Operate on all of them at once with actions, setters, or properties.
  • Eliminate anonymous inner-classes for listeners by annotating methods with @OnClick and others.
  • Eliminate resource lookups by using resource annotations on fields.

For documentation and additional information see the website.
