Various Android examples based on what comes to my mind!

Table of Contents

1. Navigation Graph & Bottom Navigation Bar & MVI & Data Binding

• Use Bottom Navigation Bar
• Fragments
• Navigation Graph
• LiveData
• Data Binding (one-way & two-way)
• Model-View-ViewModel design pattern
• Unit Testing
• Instrumented Testing

2. Hilt & MVVM & Data Binding & Clean Architecture & Reactive

• Hilt in a simple application
• A multi-module project
• Clean Architecture
• Reactive Programming
• Data Binding
• MVVM Pattern
• Variants & Flavours
• Unit Testing
• Instrumented Testing

3. Simple Workshop Projects

• Use these projects in a basic level workshop
• Explain and apply clean code techniques
• Simple Unit testing cases
• Simple instrumented testing cases
• Test and debug any issues found in this projects

4. MVI With State Pattern

• Very simple UI (no effort to understand)
• Implement MVI pattern using OO State Design Pattern

5. Jetpack Compose Example

• Use Main UI Components (List, Tabs and Pager, Loading)
• Use MVI pattern (a possible implementation)

6. Double Sticky Header Example

• Not a perfect but a good implementation of a LazyColumn with double sticky headers
• It also shows an implementation of indexed Column bond in a LazyColumn

7. Request Permissions

• Request permission
• Keep track of granted/denied/never ask again permissions

8. Dog Breeds

• Jetpack Compose
• Jetpack Compose Navigation
• Jetpack Paging Library
• Kotlin Coroutines
• Kotlin Flow (StateFlow, SharedFlow)
• Dependency Injection (Hilt)
• Retrofit
• Clean architecture
• Testing (Unit, Coroutines Unit, UI Testing, MockWebServer)

9. Room SQLite Example

• Create DB
• Execute simple queries to DB
• Experiment with DB relationship from code and avoid lengthy queries

10. Sign up / Sign in

• Android Keystore
• Biometrics
• Encryption for persistence (Read and Save user password)

11. Gradle Example

• Insert libraries:
  • From local folder
  • From local repository
• Create a sample task to show the difference between configuration and execution phase
• Create a custom task to rename output file per flavor
• Modify the above custom task to:
  • A new binary plugin (TODO)
  • A new script plugin
• Create new tasks dynamically
• Run gradle tasks (dependsOn, mustRunAfter doLast, doFirst) and use attributes in command line (profiling)
• Gradle Android properties (split apk, manual shrinking)

12. Jetpack Compose Navigation(Very Bad example of using a navigation module.)

• Modular application (3 feature modules, navigation, app)
• Navigation module
• Nested Navigation
• Weird navigation flow (Home Screen -> Screen 1 -> Screen 1_1 -> back to Home Screen directly, etc)

13. Dagger2 Example

• [Ch.11, 12] Use different Subcomponents:
  • ApplicationComponent
  • ActivityComponent (Subcomponent of `ApplicationComponent)
  • FragmentComponent (Subcomponent of `ActivityComponent)
• [Ch.11] Use different Scopes(ApplicationScope, ActivityScope, FragmentScope)
• [Ch.9] Use Qualifiers (@Named) and create new annotation classes to submit qualifiers
• [Ch.9] Allow optional binding (@BindsOptionalOf) (TODO)
• [Ch.8] Break cyclic dependency with Provider<T> (TODO)
• [Ch.8] Use @Provides in object and in abstract and see the one file per @Provides function generated (TODO)
• [Ch.10] Build above components using Component.Builder and Component.Factory (with @BindsInstance) (this example contains only Factory pattern)
• [Ch.13, 14] Dagger multibinding for ViewModels (will not do)

14. KMM Example

• Use KMM for sharing the logic between Android/iOS/Desktop (unable to work on iOS environment)
• Use buildSrc module
• Integrate Ktor for KMM network calls
• Integrate Insert-Koin for DI
• Integrate SQLDelight for DB functionality
• Implement Unit Tests with Insert-Koin

15. List Application

• Use of AsyncListDiffer for your RecyclerView Adapter
• Use property delegation instead of inheritance

16. Persistence Example Application

• Use of Shared Preferences DataStore
• Use of Protocol Buffer DataStore

17. Netflic Clone Example

• Implement Netflix's scroll behaviour

No. Project_Name

• Use Tabbed Activity
• Fragments
• Navigation Graph
• Model-View-Intent architecture using Uniflow
• Dagger 2
• Unit Testing
• Instrumented Testing
