Dependency Injection for Android

Today, dependency injection is widely adopted across various programming languages and platforms, including Java, Kotlin, C#, and JavaScript, among others. It can reduce boilerplate code and time consuming. For android development , there are two popular dependency injection. They are Hilt and Koin.

Hilt ( Compile Time )

Pros

• Great Community : Provided and maintained by Google
• Compile Time Checking - Code are generated at compile time and can show errors
• Good Performance - Resolving dependencies at compile time provides good performance?

Cons

• Long build time : Because of code generate at compile time, it will consume time.
• Complex Setup : It can be challenging for developers who are new to dependency injection.

Koin ( Runtime Type )

Pros?

• Lightweight :?Koin provider smaller files size than Hilt
• Easy to setup : More easier than Hilt

Cons

1 : No Compile Error : Koin don’t provide compile time error. Therefore , it can lead to runtime error if dependencies are not configured.

2 : Bad Performance?: Resolve dependencies at runtime and it can effect the performance.

I prefer Hilt because of google is maintained with best android principles and compile checking error. But you can choose which one is suitable with the project.
