Moxy

Maven Central

Moxy 2 is out! Check out the migration guide and give it a try!

Moxy is a library that allows for hassle-free implementation of the MVP pattern in an Android Application. Without troubles of lifecycle and boilerplate code!

Illustration of how Moxy is working: schematic_using

Capabilities

Moxy has a few killer features:

  • Presenter stays alive when Activity is being recreated (it simplifies multithread handling)
  • Automatical restoration of all content in the recreated Activity (including additional dynamic content)

Example

View interface

interface MainView : MvpView {

    @AddToEndSingle
    fun displayUser(user: User)
}

class MainActivity : MvpAppCompatActivity(R.layout.activity_main), MainView {

    private val presenter by moxyPresenter { MainPresenter() }

    override fun displayUser(user: User) {
        userLayout.showUser(user)
    }
}

Presenter

class MainPresenter : MvpPresenter<MainView>() {
    override fun onFirstViewAttach() {
        viewState.showUser(getCurrentUser())
    }
}

Inject with Dagger2

Kotlin

@Inject
lateinit var presenterProvider: Provider<MainPresenter>

private val presenter by moxyPresenter { presenterProvider.get() }

Java

@InjectPresenter
MainPresenter presenter;

@Inject
Provider<MainPresenter> presenterProvider;

@ProvidePresenter
MainPresenter providePresenter() {
    return presenterProvider.get();
}

Android studio and Intellij templates

We will change this template in future In order to avoid tedious task of writing boilerplate code for binding activities, fragments and its presentation parts, we recommend use of Android Studio templates for Moxy.

Integration

Please replace moxyVersion with the latest version number: Bintray

Base modules

Java

dependencies {
    // ...
    implementation "com.github.moxy-community:moxy:$moxyVersion"
    annotationProcessor "com.github.moxy-community:moxy-compiler:$moxyVersion"
}

Kotlin

apply plugin: 'kotlin-kapt'
// ...
dependencies {
    // ...
    implementation "com.github.moxy-community:moxy:$moxyVersion"
    kapt "com.github.moxy-community:moxy-compiler:$moxyVersion"
}

Java 8

Moxy uses Java 8 features, so you also need to specify source and target compatibility for each Module that uses Moxy:

android {
    ...
    // For Java projects
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    // For Kotlin projects
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Default Android module

For additional base view classes MvpActivity and MvpFragment add this:

implementation "com.github.moxy-community:moxy-android:$moxyVersion"

AppCompat module

If you are using AppCompat, you'll need MvpAppCompatActivity and MvpAppCompatFragment classes. Add this:

implementation "com.github.moxy-community:moxy-app-compat:$moxyVersion"

AndroidX module

If you're using AndroidX, you'll need a different implementation for MvpAppCompatActivity and MvpAppCompatFragment classes. Use this one:

implementation "com.github.moxy-community:moxy-androidx:$moxyVersion"

AndroidX (Google material) module

If you're using Google material, use MvpBottomSheetDialogFragment and add this:

implementation "com.github.moxy-community:moxy-material:$moxyVersion"

Kotlin extensions

Declare presenters in your views using property delegate:

class MyFragment: MvpFragment() {
    ...
    private val presenter by moxyPresenter { presenterProvider.get() }
    ...
}

Launch coroutines in presenter scope:

class MyPresenter : MvpPresenter<MvpView>() {
    override fun onFirstViewAttach() {
        presenterScope.launch {
            // Coroutine that will be canceled when presenter is destroyed
        }
    }
}

To use MvpDelegateHolder.moxyPresenter and MvpPresenter.presenterScope, add this:

implementation "com.github.moxy-community:moxy-ktx:$moxyVersion"

New Features and Compiler option for Migration from old version

By default, each MvpView method must have an annotation @StateStrategyType. In the version 1 of Moxy it was allowed to omit stategies for methods. In this case a default strategy was applied.

You can fallback to the old behavior. To do this, set the disableEmptyStrategyCheck parameter to true.

disableEmptyStrategyCheck : 'true'

In this case the default strategy will be AddToEndSingleStrategy. In the old version the default strategy was AddToEndStrategy.

To change default strategy provide for the defaultMoxyStrategy parameter a full class name of the new default strategy.

defaultMoxyStrategy : 'moxy.viewstate.strategy.OneExecutionStateStrategy'

If the compiler finds MvpView method without the @StateStrategyType annotation, it'd show an error via standard method for notifying about compilation problems. For ease of migration from older versions we have provided an additional mechanism: EmptyStrategyHelper. It collects all the errors associated with an empty strategy in one place. Using it, you can easily navigate from the EmptyStrategyHelper directly to the method with a missing strategy.

To switch the error output method enable this option

enableEmptyStrategyHelper : 'true'

To enable Isolating incremental annotation processor mode for Moxy processor use this option

moxyEnableIsolatingProcessing : 'true'

Use this option for faster incremental builds. You can read about differences between Isolating and Aggreagating modes and Gradle incremental annotation processing support in Gradle documentation. Warning! This option is experimental for now. It should work fine, but we prefer to make this transition as safe as possible. If you'll encounter compilation problems after enabling this option, please feel free to report an ussue. Hopefully we will enable isolating annotation processor mode by default after several releases.

How to correctly use compilation flags check out the sample-app build.gradle file

Plugin

This plugin automates work with strategies You can download it here https://plugins.jetbrains.com/plugin/13679-moxy-strategy/versions developing here https://github.com/Maksim-Novikov/moxy-strategy-plugin

ProGuard\R8

If you are using R8 then no additional configuration required. If you use ProGuard then you have to manually add rules from this file.

Road Map

  • [✓] Provide a migration tool from com.arello-mobile.moxy and its default strategy
  • [✓] Kotlin incremental compilation support
  • [✓] Remove reflectors and common presenter store
  • [✓] Add delivery module support
  • [х] Add separate Annotation Processor for migration
  • [✓] Research possibility of removing @InjectViewState annotation
  • Provide Runtime Implementation
