October

Android Framework that aims to provide a quick way to implement Clean Architecture.

Some features:

• Safe Model View Presenter architecture following standard Android lifecycle.
• Fast and automatic dependency injection using Dagger 2.
• Provides some Repository Strategy sources.
• Error handling interface for latest Retrofit version.

Show me the code:

/**
 * Presenters respect the Android lifecycle and convention methods.
 * Common lifecycle Activity methods are going to be delegated on the Presenter by October.
 */
@PerActivity // Per Activity scope
public class SamplePresenter extends OctoberPresenter<ISampleView> 
    implements ISamplePresenter<ISampleView> {

    @Inject
    SampleUseCase sampleUseCase;
    
    @Inject
    public SamplePresenter() {}
    
    @Override
    public void onCreate() {
        super.onCreate();
        
        // Setup Loading Dialog by default
        attachLoading(sampleUseCase); // (see wikis)
    }
    
    @Override
    public void onViewCreated() {
        super.onViewCreated();
        
        // Start loading some data
        sampleUseCase
            .asObservable()
            .compose(bindToLifecycle())
            .subscribe(new SampleSubscriber())
    }
    
    class SampleSubscriber extends OctoberSubscriber<Object> {
    
        @Override
        public void onError(OctoberException e) {
            e.printStackTrace();
            getView().showError(e.getCause().getMessage());
        }
    
        @Override
        public void onNext(Object data) {
            getView().render(data)
        }
    }
}

/**
 * October will attach and detach automatically your presenter and view respectively.
 * It is only needed to provide the Presenter interface as a parameterized type.
 */
@ActivityComponent // Automatic Dagger component injection
public class SampleActivity extends OctoberCompatActivity<ISamplePresenter> 
    implements ISampleView {

    // October binds Butterknife automatically
    @Bind(R.id.sample_textview) TextView sampleTextView;

    // You don't need to initialize any Dagger Component here in order to inject
    // Just remember to annotate you class with @ActivityComponent or @FragmentComponent
    @Inject
    Navigator navigator;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        this.setContentView(R.layout.activity_sample);
    }
    
    @OnClick(R.id.sample_button)
    public void onClick(View view) {
        getPresenter().onSampleButtonClicked();
    }
}

Dependency

Latest stable version:

In order to work with Dagger 2 and benefits from automatic dependency injection of October, you need to apply the android-apt gradle plugin to run annotation processing.

If you are working with gradle, add the dependency to your build.gradle file:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
  }
}

apply plugin: 'com.neenbedankt.android-apt'

dependencies{
    compile 'com.kuassivi.october:october:x.y.z'
    apt 'com.kuassivi.october:october-compiler:x.y.z'
}

If you are following your own Clean Architecture design or you just need to access October features from a Java module, use the following dependency in your gradle java module:

dependencies{
    compile 'com.kuassivi.october:october-core:x.y.z'
}
