Javascript Android文件提供程序错误（错误：不支持的类型和文件路径）

我试图在react native Android中实现文件系统访问，但当我尝试在XML中添加文件路径时，它显示了一个错误“错误：不支持的类型‘files path’”。我正在使用react native进行开发。如果代码中有问题，请告诉我

如果你们需要更多关于我的项目的信息，请告诉我。

你们的代码似乎很好，除非附带标签资源

main/res/xml/filepath.xml

您的文件夹树应如下图所示

/**
 * The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
 * and bundleReleaseJsAndAssets).
 * These basically call `react-native bundle` with the correct arguments during the Android build
 * cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
 * bundle directly from the development server. Below you can see all the possible configurations
 * and their defaults. If you decide to add a configuration block, make sure to add it before the
 * `apply from: "../../node_modules/react-native/react.gradle"` line.
 *
 * project.ext.react = [
 *   // the name of the generated asset file containing your JS bundle
 *   bundleAssetName: "index.android.bundle",

 *   // the entry file for bundle generation
 *   entryFile: "index.android.js",

 *   bundleInDebug: false,
 *
 *   // whether to bundle JS and assets in release mode
 *   bundleInRelease: true,
 *
 *   // whether to bundle JS and assets in another build variant (if configured).
 *   // See http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Variants
 *   // The configuration property can be in the following formats
 *   //         'bundleIn${productFlavor}${buildType}'

 *   // bundleInFreeDebug: true,
 *   // bundleInPaidRelease: true,

 *   // for example: to disable dev mode in the staging build type (if configured)
 *   devDisabledInStaging: true,

 *   //         'devDisabledIn${productFlavor}${buildType}'
