*react-native*: Not Found我无法在ANDROID API级别29中制作PDF。它在API级别28下工作得很好。所以我根据这个问题https://github.com/christopherdro/react-native-html-to-pdf/issues/189将RN版本从0.63.2从0.62.2和Gradle 3.5.3降级为3.5.2
也遵循https://github.com/christopherdro/react-native-html-to-pdf/issues/149的这一点。它显示权限错误，所以在componentDidMount()中我添加了下面这行
PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE)但还是不走运。我得到了下面的错误。

我从this link那里找到了解决方案
如果您发现您的应用程序无法创建任何文件或文件夹，则应添加
android:requestLegacyExternalStorage="true" in your `<application>` in `AndroidManifest.xml`有关更多详细信息，请访问Official Link和Other StackOverflow Question Answsers
请记住:我使用的是React Native，仅在Android API 29和更高版本中，我遇到了这个问题。

我也面临着这个问题，经过一些研究，我解决了这个问题，“目录名称必须与你设备中的目录(文件夹)相同，如果你想自定义目录，那么由于文件结构或一些本地权限，它可能在你的设备上工作，也可能不工作。如果自定义目录名称不起作用，那么你必须在目录选项中指定‘文档’或‘下载’。”
注意：
示例：
async createPDF() {
let options = {
html: '<h1>Export PDF</h1>',
fileName: 'MyPdf',
directory: 'Documents', //or Download
};
let file = await RNHTMLtoPDF.convert(options)
alert(file.filePath);
