What is dagger 2 used for?

Dagger 2 is a compile-time android dependency injection framework that uses Java Specification Request 330 and Annotations. Some of the basic annotations that are used in dagger 2 are: @Module This annotation is used over the class which is used to construct objects and provide the dependencies.

What is dagger in Java?

Dagger is a fully static, compile-time dependency injection framework for Java, Kotlin, and Android. It is an adaptation of an earlier version created by Square and now maintained by Google.

What is dagger dependency injection?

Dagger is arguably the most used Dependency Injection, or DI, framework for Android. Many Android projects use Dagger to simplify building and providing dependencies across the app. It gives you the ability to create specific scopes, modules, and components, where each forms a piece of a puzzle: The dependency graph.

Does dagger 2 use reflection?

Dagger 2 is a popular dependency injection (DI) framework for Java and especially popular in Android. The main reason is that it generates all the required code and does not use any reflection, which is slow in general but especially heavy in mobile.

Is dagger better than Guice?

To my knowledge, Dagger does generate code, while Guice and Spring rely on runtime processing, thus Dagger works faster, but requires more work on programmer side. Because of performance edge it’s good for mobile (Android) development.

Is KOIN better than dagger?

If you are an Android developer, chances are you might have used Dagger, which, undoubtedly, is a great library to implement DI. So I did some digging and found this cool, lightweight library called Koin(with multi-platform support). With less learning curve and boilerplate code, it seems better than Dagger2.

How do you use a dagger injection?

3. Exercise: Dependency injection with Dagger 2

  1. 3.1. Create example project for the usage of Dagger 2.
  2. 3.2. Define or adjust Maven build file.
  3. 3.3. Define classes which have a dependency.
  4. 3.4. Define modules which provides dependencies.
  5. 3.5. Define components.
  6. 3.6. Use the generated dagger code.

Which is better dagger or KOIN?

Dagger needs to use an annotation processor to scan our code and generate appropriate classes. It may take some time and it may slow down our build. On the other hand, because Koin resolves dependencies at runtime it has slightly worse runtime performance.
