Pros of Dagger

• More actively maintained with frequent updates
• Broader scope, supporting dependency injection across various Android components
• Extensive documentation and community support

Cons of Dagger

• Steeper learning curve due to more complex API
• Requires more boilerplate code
• Can increase compile times for larger projects

Code Comparison

Dagger:

@Module
public class AppModule {
    @Provides
    @Singleton
    SharedPreferences provideSharedPreferences(Application application) {
        return PreferenceManager.getDefaultSharedPreferences(application);
    }
}

Mortar:

public class MyPresenter extends Presenter<MyView> {
    @Override
    protected void onLoad(Bundle savedInstanceState) {
        super.onLoad(savedInstanceState);
        getView().showMessage("Hello, Mortar!");
    }
}

Summary

Dagger is a more comprehensive dependency injection framework with wider adoption and active development. It offers greater flexibility but comes with increased complexity. Mortar, while simpler, focuses specifically on MVP architecture and has seen less recent development. The choice between the two depends on project requirements, team expertise, and desired architectural patterns.

Pros of Koin

• Lightweight and easy to set up, with minimal boilerplate code
• Supports Kotlin multiplatform projects
• Provides a DSL for dependency declaration, making it more intuitive for Kotlin developers

Cons of Koin

• Lacks compile-time safety, as dependencies are resolved at runtime
• May have a steeper learning curve for developers new to dependency injection
• Limited features compared to more robust DI frameworks

Code Comparison

Koin:

val myModule = module {
    single { MyService() }
    factory { MyViewModel(get()) }
}

Mortar:

@Module
public class MyModule {
    @Provides @Singleton
    MyService provideMyService() {
        return new MyService();
    }
}

Key Differences

• Koin is specifically designed for Kotlin, while Mortar is Java-based
• Mortar uses a more traditional annotation-based approach, while Koin utilizes a DSL
• Koin focuses on simplicity and ease of use, whereas Mortar provides more advanced features for complex applications

Use Cases

• Koin: Ideal for small to medium-sized Kotlin projects, especially those targeting multiple platforms
• Mortar: Better suited for large-scale Java applications with complex dependency graphs and advanced requirements

Both libraries aim to simplify dependency injection, but they cater to different ecosystems and project sizes. The choice between them depends on the specific needs of your project and your preferred programming language.

Pros of RIBs

• More comprehensive architecture, covering routing and business logic
• Better suited for large-scale applications with complex navigation
• Active development and community support

Cons of RIBs

• Steeper learning curve due to its complexity
• May be overkill for smaller projects
• Requires more boilerplate code

Code Comparison

RIBs:

class ExampleRouter(
    interactor: ExampleInteractor,
    component: ExampleBuilder.Component
) : Router<ExampleInteractor, ExampleBuilder.Component>(interactor, component) {
    // Router implementation
}

Mortar:

@Layout(R.layout.example_view)
public class ExampleView extends LinearLayout {
    @Inject ExamplePresenter presenter;

    public ExampleView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // View implementation
    }
}

Key Differences

• RIBs uses a more modular approach with separate components for routing, interacting, and building
• Mortar focuses on view-presenter coupling and scope management
• RIBs is written in Kotlin, while Mortar is in Java
• RIBs has a more active development cycle and larger community
• Mortar is simpler to implement for basic MVP patterns

Use Cases

• Choose RIBs for large, complex Android applications with intricate navigation
• Opt for Mortar in smaller projects or when a lightweight MVP framework is sufficient

Pros of Mavericks

• More recent development and active maintenance
• Broader scope, supporting multiple cloud providers and deployment options
• Enhanced flexibility for custom workflows and integrations

Cons of Mavericks

• Steeper learning curve due to increased complexity
• Less focused on specific use cases compared to Mortar's Hadoop-centric approach
• Potentially more resource-intensive for smaller projects

Code Comparison

Mortar (Pig Latin):

REGISTER 'udfs.jar';
data = LOAD 'input' AS (name:chararray, age:int);
filtered = FILTER data BY age >= 18;
STORE filtered INTO 'output';

Mavericks (Python):

from mavericks import Job, Step

job = Job()
job.add_step(Step(
    name='filter_data',
    input='s3://input',
    output='s3://output',
    mapper='filter_mapper.py',
    reducer='filter_reducer.py'
))
job.run()

Summary

Mortar focuses on simplifying Hadoop workflows with Pig Latin, while Mavericks offers a more versatile approach to data processing across various cloud platforms. Mortar may be easier for Hadoop-specific tasks, but Mavericks provides greater flexibility for diverse data processing needs. The choice between them depends on the specific requirements of your project and your team's expertise.

Pros of Toothpick

• Lightweight and fast dependency injection framework
• Supports both runtime and compile-time dependency resolution
• Offers easier testing and better code organization

Cons of Toothpick

• Steeper learning curve for developers new to dependency injection
• Less mature and smaller community compared to Mortar
• May require more setup and configuration for complex projects

Code Comparison

Toothpick:

@Inject
public MyClass(Dependency dependency) {
    // Constructor injection
}

Toothpick.inject(this, Toothpick.openScope(this));

Mortar:

@Inject
MyClass myClass;

ObjectGraph objectGraph = ObjectGraph.create(new MyModule());
objectGraph.inject(this);

Both frameworks use annotations for dependency injection, but Toothpick offers more flexibility in scope management and supports constructor injection out of the box. Mortar, on the other hand, relies on field injection and requires more setup for custom scopes.

Toothpick provides a more modern approach to dependency injection in Android development, while Mortar offers a simpler, more established solution. The choice between the two depends on project requirements, team expertise, and desired features.
