Main libraries and concepts

• Android SDK, JDK 1.8 and Kotlin
• Reactive programming with RxJava2 for asynchronous tasks
• Retrofit - for simple REST implementation

Build

Project uses Gradle as build system. You can find main gradle config for Android app module here: app/build.gradle

Code organisation rules:

Basic

• All or no arguments should be named when pass to function, partial naming is not allowed

Kotlin

• Order of declarations inside class or file: val, var, constructor, init, fun, private fun

DataBindings

• All general function's annotated with @BindingAdapter should be stored in *.databindings package, filename should be 'ViewName'Bindings.kt.
• @BindingAdapter functions that couldn't be reused should be stored in file that contains related VM or should be grouped in separate file named 'Feature'Bindings.kt
• All all bindings in xml should start with bind: prefix
• All ViewModels in XML should be named vm

Gradle

• All lib and gradle plugin versions should be stored in root build.gradle file.

Rx

• Subscribing to observable allowed only with subscribeBy or bindSubscribe extension methods.
