Moxy

Moxy is a library that helps to use MVP pattern when you do the Android Application. Without problems of lifecycle and boilerplate code!

The main idea of using Moxy:

Capabilities

Moxy has a few killer features in other ways:

  • Presenter stay alive when Activity recreated(it simplify work with multithreading)
  • Automatically restore all that user see when Activity recreated(including dynamic content is added)
  • Capability to changes of many Views from one Presenter

Sample

View interface

interface MainView : MvpView {

    @StateStrategyType(AddToEndSingleStrategy::class)
 fun printLog(msg: String)
}

class MainActivity : MvpAppCompatActivity(), MainView {
 
 @InjectPresenter
 internal lateinit var presenter: MainPresenter
 
 override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)
  setContentView(R.layout.activity_main)
 }
 
 override fun printLog(msg: String) {
  Log.e(TAG, "printLog : msg : $msg activity hash code : ${hashCode()}")
 }
 
 companion object {
  const val TAG = "MoxyDebug"
 }
}

Presenter

@InjectViewState
class MainPresenter : MvpPresenter<MainView>() {
 override fun onFirstViewAttach() {
  super.onFirstViewAttach()
  Log.e(MainActivity.TAG, "presenter hash code : ${hashCode()}")
  viewState.printLog("TEST")
 }
}

Inject with Dagger2

 @Inject
 lateinit var daggerPresenter: Lazy<MainPresenter>
 
 @InjectPresenter
 lateinit var presenter: MainPresenter
 
 @ProvidePresenter
 fun providePresenter(): MainPresenter = daggerPresenter.get()

Android studio and Intellij templates

We will change this template in future In order to avoid boilerplate code creating for binding activity, fragments and its presentation part, we propose to use Android Studio templates for Moxy.

Integration

(Please replace moxyVersion with the latest version number: )

Base modules integration:

implementation 'com.github.moxy-community:moxy:moxyVersion'

Java project

annotationProcessor 'com.github.moxy-community:moxy-compiler:moxyVersion'

Kotlin

apply plugin: 'kotlin-kapt'
kapt 'com.github.moxy-community:moxy-compiler:moxyVersion'

Default android module integration

For additional base view classes MvpActivity and MvpFragment add this:

implementation 'com.github.moxy-community:moxy-android:moxyVersion'

AppCompat module integration

If you use AppCompat, use MvpAppCompatActivity and MvpAppCompatFragment add this:

implementation 'com.github.moxy-community:moxy-app-compat:moxyVersion'

AndroidX module integration

If you use AndroidX, use MvpAppCompatActivity and MvpAppCompatFragment add this:

implementation 'com.github.moxy-community:moxy-androidx:moxyVersion'

AndroidX(Google material) module integration

If you use google material, use MvpBottomSheetDialogFragment add this:

implementation 'com.github.moxy-community:moxy-material:moxyVersion'

New Features and Compiler option for Migration from old version

By default, each MvpView method must have an annotation @StateStrategyType. In the old version of Moxy, it was allowed to miss strategy for methods. In this case, the 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 old version default strategy was AddToEndStrategy.

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

defaultMoxyStrategy : 'moxy.viewstate.strategy.OneExecutionStateStrategy'

If compiler finds MvpView method without annotation @StateStrategyType it show this error with 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 the option

enableEmptyStrategyHelper : 'true'

How to correctly use compilation flags see at sample-app build.gradle file

ProGuard\R8

Moxy project already includes ProGuard rule files, no additional configuration required.

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
  • [ ]Provide Runtime Implementation
