It still feels like shoe-horning to use dagger in my apps (e.g. CabThrottle).

Reactive … Potentially interesting or totally hyped:

• http://reactivex.io/ and https://github.com/ReactiveX/RxJava -- an observer pattern (the "reverse" of a subscriber pattern) to do async operations.
• It has stuff for Android (https://github.com/ReactiveX/RxAndroid).
• Potential: for tasks that involve multiple AsyncTasks (e.g. google play login) or for replacing my event bus. (huh, not really?)

Unrelated:

• Dokan, a user-mode file system for Windows. https://dokan-dev.github.io/
