React Native - 导航 to/from 一个页面后取消引用空指针，该页面包含嵌入在其自己的 WebView 中的多个推文

Question

我目前正在为工作构建的应用主要侧重于显示文章。其中一些包含 Twitter 嵌入（在网络版本上）并且由于 API 由我们的两个应用程序共享，我也收到嵌入为 HTML。每当我尝试在 WebView 中显示推文并将源设置为 HTML 和用于样式的 Twitter JS 脚本时，页面要么正确加载但在我按回（使用 react-navigation）时崩溃，要么它只是崩溃加载但仅在 ANDROID.

我试过以下方法：

在那边也使用社区支持的 WebView package instead of the built-in one. I have opened an issue。
从 WebView 中删除 JS 脚本。
改用 injectedJavaScript 道具。
安装 TwitterKit 以使用本机嵌入，不幸的是，Twitter 不再支持它了:(

这是我呈现 WebView 的方式：

const JS = '<script type="text/javascript" src="https://platform.twitter.com/widgets.js"></script>';
return (
    <View
        key={content.embed._id} 
        style={[{ overflow : "hidden", marginTop : 15, marginStart : 15 }]}>
        <WebView 
            scrollEnabled={false}
            style={{ height : 150, width : Dimensions.get('window').width - 30 }}
            source={{ html : content.embed.html + JS }} />
    </View>
);

这是来自 Android Studio 的堆栈跟踪（我什至没有 RedBox，只是一个普通的旧硬崩溃）。

Answer 1

所以我在社区支持的 WebView github 页面上做了更多的挖掘，结果发现 androidHardwareAccelerationDisabled 是 boolean。我尝试将其设置为 true，它似乎解决了问题！

<Webview
    androidHardwareAccelerationDisabled
    ... 
/>

Answer 2

我加了

android:hardwareAccelerated="false"

在 android 清单文件中，它解决了问题。
