mortar - a simple library that makes it easy to pair thin views with dedicated controllers, isolated from most of the vagaries of the Activity life cycle.

Mortar eases the use of Dagger to divide Android apps into composable modules. It is not a framework: there are no abstract Application or Activity classes here. Mortar eschews magic. Rather, Mortar is a simple library that makes it easy to pair thin views with dedicated controllers (Presenters), isolated from most of the vagaries of the Activity life cycle. The patterns it encourages have evolved in parallel across several Android teams at Square.

Mortar relies on Dagger, and of course the Android runtime, but those are its only direct dependencies. That said, it works very well with Retrofit, Flow and RxJava. Butterknife can be a fun partner too. (Use of all of these libraries is illustrated in the sample app.)
