- An understanding of Android development
Audience
- Software Architects
Overview
Dagger 2 is an injection framework for Android applications. Using Dagger, users can implement pure dependency injection without involving any third-party frameworks all while improving architecture structure and long-term maintainability.
This instructor-led, live training (online or onsite) is aimed at software architects who wish to use Dagger 2 for dependency injection in Android applications.
By the end of this training, participants will be able to:
- Set up a project with dependency injection with Dagger 2.
- Integrate Dagger 2 into an Android application.
- Implement dependency injection without using third-party frameworks.
Format of the Course
- Interactive lecture and discussion.
- Lots of exercises and practice.
- Hands-on implementation in a live-lab environment.
