Android Boilerplate Kotlin

Ribot Sample Android app rewritten using Kotlin. It demonstrates the architecture, tools and guidelines that they use when developing for the Android platform (https://github.com/ribot/android-guidelines)

DISCLAIMER: This is not an official Ribot repository.

Libraries and tools included:

• Support libraries
• RecyclerViews and CardViews
• RxJava and RxAndroid
• Retrofit 2
• Dagger 2
• SqlBrite
• Butterknife
• Timber
• Glide
• Functional tests with Espresso
• Robolectric
• Mockito

Requirements

• JDK 1.8
• Android SDK.
• Android N (API 24) .
• Kotlin 1.0.4.
• Latest Android SDK Tools and build tools.

TODO

• Functional Tests (Waiting dexmaker support for mockito 2.x)
• Static code analysis

Architecture

This project follows ribot's Android architecture guidelines that are based on MVP (Model View Presenter). Read more about them here.

How to implement a new screen following MVP

Imagine you have to implement a sign in screen.

1. Create a new package under ui called signin
2. Create an new Activity called ActivitySignIn. You could also use a Fragment.
3. Define the view interface that your Activity is going to implement. Create a new interface called SignInMvpView that extends MvpView. Add the methods that you think will be necessary, e.g. showSignInSuccessful()
4. Create a SignInPresenter class that extends BasePresenter<SignInMvpView>
5. Implement the methods in SignInPresenter that your Activity requires to perform the necessary actions, e.g. signIn(String email). Once the sign in action finishes you should call getMvpView().showSignInSuccessful().
6. Create a SignInPresenterTestand write unit tests for signIn(email). Remember to mock the SignInMvpView and also the DataManager.
7. Make your ActivitySignIn implement SignInMvpView and implement the required methods like showSignInSuccessful()
8. In your activity, inject a new instance of SignInPresenter and call presenter.attachView(this) from onCreate and presenter.detachView() from onDestroy(). Also, set up a click listener in your button that calls presenter.signIn(email).

Code Quality

This project integrates a combination of unit tests, functional test and code analysis tools.

Tests

To run unit tests on your machine:

./gradlew test

To run functional tests on connected devices:

./gradlew connectedAndroidTest

Note: For Android Studio to use syntax highlighting for Automated tests and Unit tests you must switch the Build Variant to the desired mode.

New project setup

To quickly start a new project from this boilerplate follow the next steps:

• Download this repository as a zip.
• Change the package name.
  • Rename packages in main, androidTest and test using Android Studio.
  • In app/build.gradle file, packageName and testInstrumentationRunner.
  • In src/main/AndroidManifest.xml and src/debug/AndroidManifest.xml.
• Create a new git repository, see GitHub tutorial.
• Replace the example code with your app code following the same architecture.
• In app/build.gradle add the signing config to enable release versions.
• Add Fabric API key and secret to fabric.properties and uncomment Fabric plugin set up in app/build.gradle
• Update proguard-rules.pro to keep models (see TODO in file) and add extra rules to file if needed.
• Update README with information relevant to the new project.
• Update LICENSE to match the requirements of the new project.
