React Native Android GIF

React Native is a popular framework used to build mobile applications. With React Native, we can create a cross-platform application using a single codebase. In this article, we will discuss how to implement GIFs in a React Native Android application using Java.

Getting Started

Before we start, ensure that you have set up your React Native environment by following the official documentation provided by React Native. We will also need to install the following libraries:

• react-native-fast-image

• lottie-react-native

• rn-fetch-blob

Once you have installed these libraries, we can proceed with the implementation.

Implementation

We will be using lottie-react-native to display our GIFs. This library provides excellent capabilities for dealing with animations. The following steps will guide us through implementing the GIFs in our project:

1. Import the libraries in our App.js file:

import LottieView from 'lottie-react-native';
import FastImage from 'react-native-fast-image';
import RNFetchBlob from 'rn-fetch-blob';

2. Load the GIF into a FastImage component and display it using the LottieView. We can do this by following the example below:

import React, { useEffect, useState } from 'react';
import { View, StyleSheet } from 'react-native';
import LottieView from 'lottie-react-native';
import FastImage from 'react-native-fast-image';
import RNFetchBlob from 'rn-fetch-blob';

const App = () => {
  const [gif, setGif] = useState(null);

  useEffect(() => {
    fetchGif();
  }, []);

  const fetchGif = async () => {
    const url = 'https://media.giphy.com/media/du3J3cXyzhj75IOgvA/giphy.gif';

    const response = await RNFetchBlob.fetch('GET', url);

    const res = await response.data;

    setGif(res);
  }

  return (
    <View style={styles.container}>
      <LottieView
        source={{ uri: 'data:application/json,' + JSON.stringify(gif) }}
        autoPlay
        loop
      />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

export default App;

In the code above, we are fetching the GIF from a URL using rn-fetch-blob and setting it as the source of our FastImage component. We then display the FastImage component using the LottieView.

Conclusion

In this article, we have seen how to display GIFs in a React Native Android application using Java. We used lottie-react-native to display the GIFs and fetched them from a URL using rn-fetch-blob. Now you can incorporate GIFs into your own React Native applications using this approach!
