How to provide multiple images with Lottie on Android

When using Lottie in your Android application to display multiple images, you can leverage Lottie's animation capabilities to enhance user experience. Lottie is a library that supports Android, iOS, and Web, capable of rendering high-quality animations from JSON files. Here are the steps to use Lottie on Android to display multiple images:

Step 1: Add Lottie Dependency

First, add Lottie's dependency to your project's build.gradle file:

gradle
dependencies {
    implementation 'com.airbnb.android:lottie:3.4.0'
}

Step 2: Create Lottie Animation Files

Use design software like Adobe After Effects to create animations and export them as JSON format using the Bodymovin plugin. Design an animation that includes all the images you want to display, with each image represented as a separate frame or scene.

Step 3: Add the Animation File to Your Project

Place the exported JSON file in the app/src/main/assets folder.

Step 4: Use LottieAnimationView in Your Layout File

Add LottieAnimationView to your layout XML file:

xml
<com.airbnb.lottie.LottieAnimationView
    android:id="@+id/lottieAnimationView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:lottie_fileName="example_animation.json"
    app:lottie_autoPlay="true"
    app:lottie_loop="true"/>

Step 5: Control Animation Playback

Control animation playback in your Activity or Fragment, for example:

java
LottieAnimationView animationView = findViewById(R.id.lottieAnimationView);

// Play animation
animationView.playAnimation();

// Jump to a specific progress point to display specific images
animationView.setProgress(0.5f);

// Pause animation
animationView.pauseAnimation();

Example Scenario

Suppose you have an e-commerce application and want to showcase multiple perspectives of a new product. Design a Lottie animation where each perspective is a separate frame, and allow users to view different perspectives by swiping or tapping buttons.

Through this approach, Lottie not only makes image display more dynamic and engaging but also significantly reduces app size, as multiple images are compressed into a single JSON file.

This is the basic process for using Lottie on Android to display multiple images, along with a practical example. Hope this helps with your project!
