How to set up DroidMVP with Dagger in an Android app?

The library provides sample projects with Dagger integration; you can extend BaseActivity or BaseFragment from the sample-dagger module and inject presenters using DI frameworks, as detailed in the README's dependency injection section.

DroidMVP vs MVVM: which should I use for Android development?

DroidMVP enforces strict separation with MVP and Passive View, ideal for testability and clean architecture, while MVVM with LiveData offers built-in lifecycle awareness and reactive data binding. Choose DroidMVP if you prioritize presenter logic isolation over Google's recommended patterns.

How to handle screen rotation with DroidMVP?

Use the Presentation Model pattern combined with Passive View to persist UI state; the sample-parcelable project shows how to make PresentationModel Parcelable for saving instance state during configuration changes.

Can I use DroidMVP with Kotlin coroutines?

Yes, but it requires manual integration since DroidMVP doesn't provide built-in support; you'll need to handle coroutines in presenters and ensure proper lifecycle management, which isn't documented in the README.

What are the benefits of Passive View in DroidMVP?

Passive View makes the UI layer dumb by delegating all logic to presenters, enhancing testability by removing Android dependencies from business logic, as explained in the linked Medium article on Presentation Model and Passive View.

Is DroidMVP compatible with Jetpack Compose?

Not directly, as DroidMVP is designed for traditional Android Views; adapting it to Compose would require significant re-architecture due to Compose's declarative and reactive nature, which isn't addressed in the library.

What is DroidMVP?

DroidMVP is a lightweight Android library that helps developers implement the Model-View-Presenter (MVP) pattern, along with Passive View and Presentation Model patterns, in their Android applications. It provides a structured way to separate business logic from UI, making apps more maintainable and testable. The library reduces boilerplate code and offers flexibility through composition and dependency injection support.

Target Audience

Android developers looking to adopt clean architecture patterns like MVP, Passive View, or Presentation Model in their apps. It's particularly useful for teams prioritizing testability and maintainability in medium to large Android projects.

Value Proposition

Developers choose DroidMVP for its simplicity, flexibility, and focus on clean architecture principles. It uniquely combines Passive View and Presentation Model with MVP, offers composition over inheritance, and integrates easily with dependency injection frameworks like Dagger.

Overview

Small Android library to help you incorporate MVP, Passive View and Presentation Model patterns in your app

Use Cases

Best For

Implementing MVP architecture in Android apps
Building testable Android UIs with Passive View
Managing complex UI state with Presentation Model
Reducing boilerplate code in Android MVP implementations
Integrating dependency injection with Android architecture patterns
Adopting clean architecture principles in Android development

Not Ideal For

Projects adopting Jetpack Compose or modern reactive UI frameworks, as DroidMVP is designed for traditional Android View-based UIs.
Teams using Android Architecture Components like ViewModel and LiveData, since DroidMVP provides an overlapping but alternative architecture.
Rapid prototyping or very small apps where the overhead of implementing MVP patterns is unjustified.

Pros & Cons

Pros

Pattern Flexibility

Supports MVP, Passive View, and Presentation Model, allowing developers to combine patterns for complex UI state management, as highlighted in the README's explanation article.

DI Integration

Designed to work seamlessly with dependency injection frameworks like Dagger, with sample projects provided for guidance on integration.

Composition Over Inheritance

Offers DroidMVPViewDelegate for cases where extending base classes isn't possible, promoting flexible code structure without locking into inheritance hierarchies.

Testability Emphasis

Encourages a passive UI layer that delegates logic to presenters, making business logic easier to unit test independently from Android framework dependencies.

Cons

Early Development Stage

With version 0.1.3, the library might be prone to breaking changes or lack the maturity of stable releases, as indicated by the low version number in the setup instructions.

Limited Modern Feature Support

Does not natively integrate with Kotlin coroutines or Flow, requiring additional setup for asynchronous operations common in modern Android apps, which isn't covered in the README.

Niche Community Adoption

Compared to official Android patterns, DroidMVP has a smaller user base, which can mean fewer resources, tutorials, and community support beyond the provided samples and articles.
