Getting Started with Hilt
Setting up Gradle
Application Class Configuration
To get started with Hilt in your Android project using Kotlin, follow these steps for setting up Gradle and configuring the Application
class:
Setting up Gradle:
In our project's build.gradle
file, make sure we have the necessary dependencies for Hilt:
buildscript {
// ...
dependencies {
// ...
classpath "com.google.dagger:hilt-android-gradle-plugin:2.40.5"
}
}
allprojects {
repositories {
// ...
mavenCentral()
}
}
In our app's build.gradle
file, apply the Hilt plugin and add the Hilt dependencies:
apply plugin: 'kotlin-kapt'
apply plugin: 'dagger.hilt.android.plugin'
android {
// ...
}
dependencies {
// ...
implementation "com.google.dagger:hilt-android:2.40.5"
kapt "com.google.dagger:hilt-android-compiler:2.40.5"
}
Application Class Configuration:
In our Application
class, add the @HiltAndroidApp
annotation to enable Hilt for our application:
import android.app.Application
import dagger.hilt.android.HiltAndroidApp
@HiltAndroidApp
class MyApplication : Application() {
// Application code
}
With these setup steps, we have configured Hilt for your Android application. The @HiltAndroidApp
annotation in the Application class tells Hilt to generate and manage the necessary components to enable dependency injection throughout our app.
Now you can start using Hilt annotations, such as @AndroidEntryPoint
, to enable dependency injection in our activities
, fragments
, view models
, and other Android
components. Hilt will take care of creating and managing the necessary dependencies for us.
