How to set it up
In this section, we will walk you through the process of setting up and utilizing Lottie animations in your Android projects. Let's dive in and unlock the captivating world of Lottie animations!
Step 1: Integrating Lottie into Your Android Project
To get started, you'll need to integrate the Lottie library into your Android project. Follow these steps:
- Open your project in Android Studio.
- Add the Lottie dependency to your app-level build.gradle file:
implementation 'com.airbnb.android:lottie:6.1.0'
- Sync your project to ensure the dependency is successfully added.
Step 2: Preparing Lottie Animation Files
Lottie animations are created using Adobe After Effects (more on this below) and exported as JSON files. You can either create your animations from scratch or explore the vast collection of pre-built animations available on websites like LottieFiles.
Once you have your animation file (e.g., animation.json), place it in the assets folder of your Android project.
Step 3: Displaying Lottie Animations
Now that you have Lottie integrated and your animation file ready, let's display the animation in your Android app:
- Add a LottieAnimationView to your layout XML file:
<com.airbnb.lottie.LottieAnimationView
? ? android:id="@+id/animationView"
? ? android:layout_width="match_parent"
? ? android:layout_height="match_parent" />
- In your Activity or Fragment, initialize the LottieAnimationView and load the animation file:
val animationView = findViewById<LottieAnimationView>(R.id.animationView) // or use view binding
animationView.setAnimation("animation.json")
animationView.playAnimation()
Step 4: Interacting with Lottie Animations
Lottie provides various methods to interact with animations and control their playback. Here are a few examples:
animationView.playAnimation()
animationView.pauseAnimation()
animationView.resumeAnimation()
animationView.setSpeed(2f) // Play at double the speed
animationView.setSpeed(-1f) // Play in reverse
//listen for events
animationView.addAnimatorListener(object : Animator.AnimatorListener {
override fun onAnimationStart(animation: Animator) { }
override fun onAnimationEnd(animation: Animator) { }
override fun onAnimationCancel(animation: Animator) { }
override fun onAnimationRepeat(animation: Animator) { }
})
Step 5: Customizing Lottie Animations
Lottie allows you to customize animations to match your app's branding and design. You can modify properties like colors, sizes, and durations programmatically:
val composition = animationView.composition // Retrieve the animation composition
composition?.let { comp ->
? ? comp.layers.forEach { layer ->
? ? ? ? // Customize properties of each layer
? ? ? ? if (layer is ShapeLayer) {
? ? ? ? ? ? layer.addColorFilter(yourColorFilter)
? ? ? ? }
? ? }
? ? animationView.setComposition(comp) // Apply the modified composition
}
You can explore the Lottie documentation for more details on customization options.

Experiment, explore, and let your creativity shine as you leverage the power of Lottie to enhance user experiences on the Android platform.
Jetpack Compose
Jetpack Compose, the modern UI toolkit for building Android apps, has gained immense popularity for its declarative approach and ease of use. If you're using Jetpack Compose in your Android app, incorporating Lottie animations is a breeze. In this section, we will explore how to integrate Lottie animations with Jetpack Compose and showcase some examples. Let's dive in!
Step 1: Load and Display a Lottie Animation
To load and display a Lottie animation in Jetpack Compose, follow these steps:
- Import the necessary Compose and Lottie classes:
import androidx.compose.foundation.Canvas
import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.runtime.*
import androidx.compose.ui.Modifier
import com.airbnb.lottie.compose.*
- Create a Composable function to display the animation:
@Composable
fun LottieAnimationExample() {
? ? val composition by rememberLottieComposition(specify your animation file path)
? ? val progress by animateLottieCompositionAsState(composition)
? ??
? ? Canvas(modifier = Modifier.fillMaxSize()) {
? ? ? ? with(lottieComposition(composition = composition, progress = progress)) {
? ? ? ? ? ? drawLottieComposition()
? ? ? ? }
? ? }
}
- In your Composable function, call the LottieAnimationExample() function to display the animation.
Step 2: Controlling the Animation
To control the playback of the Lottie animation, you can use the rememberLottieAnimationState() function and modify the animation state as needed. Here's an example:
@Composable
fun LottieAnimationExample() {
? ? val composition by rememberLottieComposition(specify your animation file path)
? ? val animationState = rememberLottieAnimationState(autoPlay = true)
? ??
? ? LottieAnimation(
? ? ? ? composition = composition,
? ? ? ? animationState = animationState,
? ? ? ? modifier = Modifier.fillMaxSize()
? ? )
}
In the above example, the animation will automatically play as soon as the Composable is rendered due to the autoPlay = true parameter. You can control the animation using the functions provided by the LottieAnimationState object, such as play(), pause(), resume(), and progress.
Step 3: Customizing Lottie Animations
Jetpack Compose makes it easy to customize Lottie animations to match your app's design and user experience. You can modify properties like size, color, and scale using Compose modifiers. Here's an example:
@Composable
fun LottieAnimationExample() {
? ? val composition by rememberLottieComposition(specify your animation file path)
? ? val animationState = rememberLottieAnimationState(autoPlay = true)
? ??
? ? LottieAnimation(
? ? ? ? composition = composition,
? ? ? ? animationState = animationState,
? ? ? ? modifier = Modifier
? ? ? ? ? ? .size(200.dp)
? ? ? ? ? ? .background(Color.White)
? ? )
}
In the example above, the animation is customized by setting its size to 200.dp and applying a white background color.
Integrating Lottie animations with Jetpack Compose is a seamless process that allows you to create engaging and visually appealing user interfaces. By following the steps outlined above, you can easily load, display, and control Lottie animations in your Jetpack Compose-based Android app. Leverage the power of Jetpack Compose's declarative nature and Lottie's animation capabilities to enhance your app's user experience and bring it to life with delightful animations. Experiment, explore, and let your creativity shine as you combine the best of both worlds.
