我创建了一个应用程序(使用React Native Expo),其中包含一些图像,例如:
<Image source={require('../assets/facebook_button.png')} />
图像位于资产目录中,我可以使用npm publish
或npm start
功能来查看它们。
问题是使用exp build:android
构建应用程序时,现在apk 不显示静态图像(但正在显示我从Internet加载的其他图像)。
这是我的app.json:
{
"expo": {
"name": "my-interesting-app",
"description": "My Interesting App",
"slug": "my-interesting-app",
"privacy": "public",
"sdkVersion": "29.0.0",
"platforms": ["ios", "android"],
"version": "1.0.0",
"orientation": "portrait",
"icon": "./assets/icon.png",
"splash": {
"image": "./assets/splash.png",
"resizeMode": "contain",
"backgroundColor": "#ffffff"
},
"updates": {
"fallbackToCacheTimeout": 0
},
"assetBundlePatterns": [
"**/*",
"assets/*"
],
"ios": {
"supportsTablet": true,
"bundleIdentifier": "com.myinteresting.myinterestingapp"
},
"android": {
"package": "com.myinteresting.myinterestingapp"
},
}
}
感谢您的帮助

尝试在加载之前缓存图像。
import React from 'react';
import { Image, Text, View } from 'react-native';
import { Asset, AppLoading } from 'expo';
export default class App extends React.Component {
state = {
isReady: false,
};
render() {
if (!this.state.isReady) {
return (
<AppLoading
startAsync={() => this._cacheResourcesAsync()}
onFinish={() => this.setState({ isReady: true })}
onError={console.warn}
/>
);
}
return (
<View style={{ flex: 1 }}>
<Image source={require('./assets/images/expo-icon.png')} />
<Image source={require('./assets/images/slack-icon.png')} />
</View>
);
}
async _cacheResourcesAsync() {
return Asset.loadAsync([
require('./assets/images/expo-icon.png'),
require('./assets/images/slack-icon.png'),
]);
}
}

是否存在可以发布快照的错误或捕获?当您不知道是什么原因导致修复时,真的很难。
