Powerful Android Apps with Jetpack Architecture

Watch the video course here: Powerful Android Apps with Jetpack Architecture.

In this course you'll learn to build a real application that interacts with the website open-api.xyz.

Open-api.xyz is a sandbox website for codingwithmitch members to practice interacting with a Rest API.

Prerequisites (Recommended not required):

1. Dagger 2

2. MVI Architecture

3. Database Caching (Retrofit + Room)

What you'll learn:

• Kotlin:
• Coroutines:
  
  1. Advanced coroutine management using jobs
  2. Cancelling active jobs
  3. Coroutine scoping
• Navigation Components:
  
  1. Bottom Navigation View with fragments
  2. Leveraging multiple navigation graphs (this is cutting edge content)
• Dagger 2:
  
  1. custom scopes, fragment injection, activity injection, Viewmodel injection
• MVI architecture:
  
  1. Basically this is MVVM with some additions
  2. State management
  3. Building a generic BaseViewModel
  4. Repository pattern (NetworkBoundResource)
• Room Persistence:
  
  1. SQLite on Android with Room Persistence library
  2. Custom queries, inserts, deletes, updates
  3. Foreign Key relationships
  4. Multiple database tables
• Cache:
  
  1. Database caching (saving data from network into local cache)
  2. Single source of truth principal
• Retrofit 2:
  
  1. Handling any type of response from server (success, error, none, etc...)
  2. Returning LiveData from Retrofit calls (Retrofit Call Adapter)
• ViewModels:
  
  1. Sharing a ViewModel between several fragments
  2. Building a powerful generic BaseViewModel
• WebViews:
  
  1. Interacting with the server through a webview (Javascript)
• SearchView:
  
  1. Programmatically implement a SearchView
  2. Execute search queries to network and db cache
• Images:
  
  1. Selecting images from phone memory
  2. Cropping images to a specific aspect ratio
  3. Setting limitations on image size and aspect ratio
  4. Uploading a cropped image to server
• Network Request Management:
  
  1. Cancelling pending network requests (Kotlin coroutines)
  2. Testing for network delays
• Pagination:
  
  1. Paginating objects returned from server and database cache
• Material Design:
  
  1. Bottom Navigation View with Fragments
  2. Customizing Bottom Navigation Icon behavior
  3. Handling Different Screen Sizes (ConstraintLayout)
  4. Material Dialogs
  5. Fragment transition animations
