我正在尝试在本机Android中实现文件系统访问，但是当我尝试在XML中添加文件路径时，它会显示错误＆＃34;错误：不支持的类型＆＃39; files-path＆＃39;＆ ＃34 ;.我正在使用本地反应进行开发。如果代码中存在问题，请与我们联系。

/**
* 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.

* // 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}'
* // 'bundleIn${buildType}'
* // bundleInFreeDebug: true,
* // bundleInPaidRelease: true,
* // bundleInBeta: true,
*
* // whether to disable dev mode in custom build variants (by default only disabled in release)
* // for example: to disable dev mode in the staging build type (if configured)
* devDisabledInStaging: true,
* // The configuration property can be in the following formats
* // 'devDisabledIn${productFlavor}${buildType}'
* // 'devDisabledIn${buildType}'

* root: "../../",

* // that we don't look at files in android/ or ios/ to determine whether the tasks are up to

你的代码看起来很好，除非封闭标签资源;
主/ RES / XML / filepath.xml
<resources>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="img" path="images/"/>
</paths>
</resources>
您的文件夹树应如下图所示
