2. What’s the worst thing that could happen
   when you’re using Android Activity as your
   page representation?

4. Caused by:
   android.content.ActivityNotFoundException: Unable to
   find explicit activity class {...}; have you declared this
   activity in your AndroidManifest.xml?

6. Task and Back Stack
   Intent intent = new Intent(LoginActivity.this, MainMenuActivity.class);
   intent.addFlags(...) // FLAG_ACTIVITY_CLEAR_TOP, NEW_TASK, etc ...
   startActivity(intent);
   finish();
   Or use `launchMode` in AndroidManifest.xml

8. What about Fragment?
   ● Introduce more complex lifecycle
   ● Never use it since last year ( expect for Google Map )
   ● ¯\_(ツ)_/¯

12. Conductor
    A small, yet full-featured framework that allows building View-based Android applications.
    Conductor provides a light-weight wrapper around standard Android Views that does just about
    everything you'd want

16. Controller
    The Controller is the View wrapper that will give you all of your lifecycle management features.
    Think of it as a lighter-weight and more predictable Fragment alternative with an easier to
    manage lifecycle.
    TL;DR this is your Fragment

18. Router
    A Router implements navigation and backstack handling for Controllers. Router objects are
    attached to Activity/containing ViewGroup pairs. Routers do not directly render or push Views to
    the container ViewGroup, but instead defer this responsibility to the ControllerChangeHandler
    specified in a given transaction.
    TL;DR this is your FragmentManager

20. ControllerChangeHandlers
    ControllerChangeHandlers are responsible for swapping the View for one Controller to the View
    of another. They can be useful for performing animations and transitions between Controllers.
    Several default ControllerChangeHandlers are included.

21. ControllerTransaction
    Transactions are used to define data about adding Controllers. RouterControllerTransactions
    are used to push a Controller to a Router with specified ControllerChangeHandlers, while
    ChildControllerTransactions are used to add child Controllers.
    TL;DR this is your FragmentTransaction
