# Mastering Hilt - Android | Kotlin | Hilt (Dagger 2) [ Part 1]

### **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:

```kotlin
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:

```kotlin
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:

```kotlin
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.
