Write your own Android Studio plugin and automate everything

Let’s face it, you spend a lot of time writing the same code over and over again. Maybe you are using the same pattern in different places.

Maybe you copy&paste some classes and layouts when you create a new Activity using MVP or MVVM. Maybe you “reuse” the same files when you create a new App. What if you could generate that code automatically? Well, you can, and I’m going to show you how by writing your own Android Studio Plugin.

In this talk, you will learn how to create a new Android Studio Plugin, create templates to generate code automatically, write live templates to insert frequently-used constructors in your code and how you can create a brand new full app in minutes putting together feature modules and templates.
