11 POP QUIZ Dagger2? Dagger Android Prince
12 ABOUT THE TALK
13 Theme: Prince of Persia Prince uses Dagger Dagger can reverse time Dahaka, (guardian of timeline) Dahaka comes to kill the Prince.
14 Analogy Prince = Us Dagger = Dagger Dahaka (Enemy) = Generated Code, Complexity
15 Analogy Developer uses Dagger Developer starts backtracking the generated code Developer is chased by the Dahaka (complexity of generated code)
16 Agenda Brief Introduction - Codes of Time Scopes - Face of the Scopes Custom Scopes Component Dependencies - Unleash the Beast Demo App Dependent Component Subcomponent Intermediate Concepts - Defeat the Dahaka Dagger Android - Befriend the Beast
17 Who? Assumption : Basic familiarity with Dagger Intermediate

26 Dagger 2 Advantages No Reflection Compile-time Graph Composition Traceable code Better
27 SCOPES FACE OF THE DAHAKA
28 Scope Annotation from javax.inject package How long a scoped instance lives What happens if : No Scope specified? Annotation is specified?
29 @Singleton Another annotation from javax.inject package Scope of dependency is throughout the application Two ways to re-use dependencies : Annotate Provider methods Annotate the Dependency class itself

50 Take Aways DONT Scope All the Things! Scoping has overheads. By-default no Scope. Scope only when needed Like for Heavy Mutable Objects
51 @ragdroid
52 @Reusable Limit the instantiation. Use when Exact same instance not needed. Not tied to any component or subcomponent. Can Have multiple sub-components caching different instances. Use for heavy immutable dependencies.
