An android project structure using kotlin and most common libraries.

Kotlin Android Scaffolding Project

Just the basic structure of a kotlin android project. Still a WIP.

Architectural approach

The idea is to follow up Android clean architecture approach:

• Architecting Android…The clean way?
• Architecting Android…The evolution

Build System approach

The build system is based on gradle, so for instance the project can be easily imported to both Android Studion and Intellij.

Testing approach

Tests are split up into Acceptance and Unit tests and essentially follow up the approach in this article I have written:

• Android Testing with Kotlin

Usage

For now, the only way to use this WIP is by cloning the repo and manually setting it up. Go to the next section to see how to get started with the main files involved in the configuration.

Setup

Once the repository is cloned, follow this up:

• You will have to rename the main packages manually.
• Configuration and dependencies versions sit on the depedencies.gradle file.
• There is a ci.gradle file for Travis and CI setup.

Dependencies

So far, these dependencies have been added:

• Android Annotations
• Android Compat
• Dagger 2
• RxJava 2
• RxAndroid 2
• Retrofit 2
• JUnit 4
• Robolectric 3
• Mockito Kotlin
• Kluent
• Espresso
• Leak Canary

Gradle tasks

Here are some useful Gradle/adb commands:

• ./gradlew clean build - Build the entire app and execute unit and integration tests plus lint check.
• ./gradlew installDebug - Install the debug apk on the current connected device.
• ./gradlew deployDebug - Install and executes the debug apk on the current connected device.
• ./gradlew runUnitTests - Execute unit and integration tests.
• ./gradlew runAcceptanceTests - Execute acceptance tests.

Next steps

• Automate all the things.
• Fix issues.
