app-mvp is a client-side JVM MVP application skeleton for simple notes keeping in Kotlin.

app-infra-rest-retrofit is an infra layer - client REST controllers that are used by client apps.

app-android is an Android app.

To create podspec files run in root project directory:

./gradlew podspec

app-ios is an iOS app.

app-flutter is an Android/iOS Flutter app.

app-javafx is a desktop JavaFX app.

Client-side application requires server-side JVM application to be running. Applications interact over HTTP REST. Make sure you run it before running Android application.

All the apps (except Flutter) use MVP design pattern (see app-mvp module):

Android and JavaFX apps just provide concrete View implementations and reuse Model and Presenter from app-mvp. In order to interact with server-side app Model has a reference to UseCase implementation (from server-side app-api). In order to pass boundary we use according Controller that implement UseCase and abstracts transport/protocol. So both apps use app-infra-rest-retrofit module with Controllers which can be easily replaced with another one.

Applications use app-api module from server-side application repository.

First, make sure:

• NotesServerApp artifacts are available on local Maven repository: clone NotesServerApp repository to any directory, build and publish it to local Maven repository or
• use Gradle composite-build: clone NotesServerApp repository to ../NotesServerApp directory (no separate building/publication is required).

In this repository root directory:

./gradlew app-android:assemble

Find compiled .apks in ./app-android/build/outputs/apk/ directories.

In this repository root directory:

./gradlew app-javafx:shadowJar

Find compiled app-javafx-all.jar "shadow" jar (includes all dependencies) in ./app-javafx/build/libs/ directory.

Compile and install podspec files for server-side and client apps in root directories:

./gradlew podspec

Install app-mvp pod in app-ios directory:

pod install

In app-flutter directory:

flutter pub get
flutter packages pub run build_runner build
flutter build apk --target-platform android-arm

One can find few unit tests that demonstrate some benefits of clean architecture for testing:

./gradlew test

One can find few unit tests in app-ios/app-iosTests. Run them in XCode.

First, create and run AVD. In this repository root directory:

./gradlew app-android:connectedAndroidTest

Make sure all the tests passed:

In app-flutter directory:

flutter test

Stop server-side app (just to test errors handling). Install Android app to your device/emulator:

adb install ./app-android/build/outputs/apk/debug/app-android-debug.apk

and run the app.

Type server-side app host and port:

Make sure you can see connection error:

Run server-side app and click "Reload" button to reload the notes list in Android app:

Click "Add" button and type note title and body:

Make sure you can see added note:

Stop server-side app (just to test errors handling). Run JavaFX app:

java -jar app-javafx/build/libs/app-javafx-all.jar  

Type server-side app host and port:

Make sure you can see connection error:

Run server-side app and click "Reload" button to reload the notes list in javafx app:

Click "Add" button and type note title and body:
