Dagger 2 Android Overview

This video is an overview of everything we covered in the dagger 2 android course.

I'm going to quickly review the following topics:

1) Creating an AppComponent
- extending DaggerApplication
- AndroidInjector

2) Creating modules and adding dependencies to modules
- @Provides
- Retrofit instance and other objects
- @Binds instead of provides (can use if no method body)

3) Injecting Activities
- ActivityBuildersModule and @ContributesAndroidInjector
- Subcomponents
- dependencies within subcomponents (passing as module to @ContributesAndroidInjector)

4) Injecting activities into activities (drawable in authactivity)

5) Injectin ViewModels
- this is pretty complicated because we have to use multibinding. I suggest rewatching the video: https://codingwithmitch.com/courses/dagger22-android/injecting-viewmodels-dagger2-android-map-multibind/

6) Injecting dependencies into ViewModels

7) Creating the SessionManager as an app-level dependency
- leveraging the SessionManager in ViewModels
- leveraging the SessionManager in a BaseActivity

8) Custom Scopes (@Singleton, @AuthScope, @MainScope)
- review the diagram and show scopes
- review the different memory addresses and @Named annotation
