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: See what's happening here in the wiki.


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


View interface

public interface HelloWorldView extends MvpView {
  void showMessage(int message);


@InjectViewState public class HelloWorldPresenter extends MvpPresenter<HelloWorldView> {
  public HelloWorldPresenter() {


View implementation

public class HelloWorldActivity extends MvpAppCompatActivity implements HelloWorldView {

@InjectPresenter  HelloWorldPresenter mHelloWorldPresenter;
private TextView mHelloWorldTextView;
@Override  protected void onCreate(Bundle savedInstanceState) {



 mHelloWorldTextView = ((TextView) findViewById(;

@Override  public void showMessage(int message) {


Here you can see "Github" sample application.

Android studio templates

In order to avoid boilerplate code creating for binding activity, fragments and its presentation part, we propose to use Android Studio templates for Moxy.

Base modules integration:

dependencies {

compile 'com.arello-mobile:moxy:1.5.3'
annotationProcessor 'com.arello-mobile:moxy-compiler:1.5.3' 

For additional base view classes MvpActivity and MvpFragment add this:

dependencies {

compile 'com.arello-mobile:moxy-android:1.5.3' 

If you are planning to use AppCompat, then you can use MvpAppCompatActivity and MvpAppCompatFragment. Then add this:

dependencies {

compile 'com.arello-mobile:moxy-app-compat:1.5.3'
compile '$support_version' 


If you are using kotlin, use kapt instead of provided/ apt dependency type and set generateStubs property of kapt to true:

dependencies {

kapt 'com.arello-mobile:moxy-compiler:1.5.3' 
 kapt {

  generateStubs = true 


Moxy is completely without reflection! No special ProGuard rules required.
