react-native-webview 在调用时崩溃应用程序

Question

我正在使用 react-native-webview 库加载网页，它在调试时工作正常，但是当我创建发布版本时。并单击选项卡加载 webview ，应用程序崩溃。以下是错误。我最后也附上了错误跟踪。

我正在使用本机反应：“0.62.0” react-native-webview : "^9.0.2",

这是我点击按钮加载 webview 屏幕时的轨迹。

Answer 1

这对我有用。我刚用过。

 expo install react-native-webview
 "react-native-webview": "8.1.1"

 import { WebView } from 'react-native-webview'
 <WebView source={{ uri: 'https://expo.io' }} style={{ marginTop: 20, height: 500 }} />

Answer 2

react-native-webview升级到9.1.3版本后出现同样的错误。降级到 9.1.1 后错误消失。版本 9.1.2 未选中。

2020.04.12更新。在版本 9.1.4 中也存在该错误。如下所述，使用 'react-native-get-random-values' 所有作品。我正在使用 CLI 版本。

2020.04.24更新。在版本 9.2.2 中，该错误已得到纠正。我删除了包 'react-native-get-random-values' 并且一切正常。

Answer 3

似乎是新版本的错误，但根据此文档 (https://github.com/react-native-community/react-native-webview/issues/1312) 可以按如下方式解决

首先安装 react-native-get-random-values，然后将其导入文件顶部

import 'react-native-get-random-values';
import React, { Component } from 'react';
import { WebView } from 'react-native-webview';
import {
  StyleSheet,
  View,
  Text,
} from 'react-native';

export default class MyWeb extends Component {
  render() {
    return (
      <View style={{ backgroundColor: 'blue',flex: 1 }}>
        <WebView
          source={{ uri: 'https://url.ngrok.io' }}
          style={{ marginTop: 20, }}
        />
      </View>
    );
  }
}

Answer 4

安装 'react-native-get-random-values' 包。

然后在你的react native app的入口文件添加"import 'react-native-get-random-values'"如下。就像 index.js 当应用程序使用 React Native CLI 创建时

import 'react-native-get-random-values';
import React, {Component} from 'react';
import { WebView } from 'react-native-webview';

class MyWebComponent extends Component {
    render() {
        return <WebView source={{ uri: 'https://reactnative.dev/' }} />;
    }
}

Answer 5

安装 react-native-get-random-values 包..之后，尝试将导入移动到文件的最顶部..

index.js

这种方式对我有用..

import 'react-native-get-random-values';
import {AppRegistry} from 'react-native';
import App from './App';
import {name as appName} from './app.json';

AppRegistry.registerComponent(appName, () => App);

Answer 6

为我解决了这个问题： `react-native-webview：“8.0.4”，

Answer 7

将属性 androidHardwareAccelerationDisabled={true} 添加到 webview

<WebView
   source={{ uri: 'https://reatnative.com' }}
   androidHardwareAccelerationDisabled={true}
/>

react-native-webview 在调用时崩溃应用程序

react-native-webview crashes application when invoked

javascript

android
