React-Native: Лотти на андроид не работает должным образом

/ 30 мая 2018

Я использую линейный градиент от lottie, код отлично работает с ios, но в Android он не вписывается в полноэкранный режим, между градиентом и видом есть некоторый отступ.На ios все работает нормально ... я пробовал много способов, покупал включая padding до 0 и даже маржу до -20, но ничего не получалось ... какое-нибудь решение?enter image description here

import React, { Component } from 'react';
import {
  Text,
  StyleSheet,
  View,
  Platform,
  Dimensions
} from 'react-native';
import SignInScreen from './src/screens/auth/SignInScreen';
import Animation from 'lottie-react-native';

 import anim from './assets/gradient_animated_background.json';
const height = Dimensions.get('window').height + 20;
const width = Dimensions.get('window').width + 20;

export default class App extends Component {
  componentDidMount() {
    this.animation.play();
  }

  render() {
    return (
      <View style={styles.container}>
          <Animation
            ref={animation => {
              this.animation = animation;
            }}
            style={{
              backgroundColor: 'red',
              height: '100%',
              width: '100%'
            }}
            loop={true}
            source={Platform.OS === 'ios' ? anim : 'gradient_animated_background.json'}
          />
       </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'blue',
    flex: 1,
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
    color: '#ffffff'
  }
});

Анимация, и когда я постоянно меняю ширину и высоту ... она принудительно пытается поддерживать радио аспект ... (хотя не уверен)

Вам не хватает только resizeMode, который не указан на странице документации, но если вы посмотрите на источник, то найдете его.

Вот что работает, если вы этого не сделаетеПотеряйте несколько пикселей: 

import React, { Component } from 'react';

import {
  StyleSheet,
  View,
  Dimensions
} from 'react-native';
import LottieView from 'lottie-react-native';
import { anim } from './assets/animation.json';

const { height, width } = Dimensions.get('window')

export default class App extends Component {
  componentDidMount() {
    this.animation.play();
  }

  render() {
    return (
      <View style={styles.container}>
          <LottieView
            ref={animation => {
              this.animation = animation;
            }}
            style={{
              width: width + 10,
              height: height,
              marginLeft: - 5
            }}
            resizeMode='cover'
            loop={true}
            source={anim}
          />
       </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'blue',
    flex: 1,
  },
});

Обратите внимание, что я экспортировал ресурс немного по-другому, так как попробовал это на https://snack.expo.io, и по некоторым причинам им не нравятся файлы JSON ?теперь активы выглядят так:

/assets/animation.json.js
