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.
- Create a new package under
ui
calledsignin
- Create an new Activity called
ActivitySignIn
. You could also use a Fragment. - Define the view interface that your Activity is going to implement. Create a new interface called
SignInMvpView
that extendsMvpView
. Add the methods that you think will be necessary, e.g.showSignInSuccessful()
- Create a
SignInPresenter
class that extendsBasePresenter<SignInMvpView>
- 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 callgetMvpView().showSignInSuccessful()
. - Create a
SignInPresenterTest
and write unit tests forsignIn(email)
. Remember to mock theSignInMvpView
and also theDataManager
. - Make your
ActivitySignIn
implementSignInMvpView
and implement the required methods likeshowSignInSuccessful()
- In your activity, inject a new instance of
SignInPresenter
and callpresenter.attachView(this)
fromonCreate
andpresenter.detachView()
fromonDestroy()
. Also, set up a click listener in your button that callspresenter.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
andtestInstrumentationRunner
. - In
src/main/AndroidManifest.xml
andsrc/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.
