Flutter：资源和资产合并：可以确定标签的类型'路径=;＆quot＆quot＆quort;＆gt;＆＃x27;

Question

我正在使用Flutter 3.0中的InappWebView软件包开发一个应用程序。在此软件包中，我们无法在Android设备中的WebView中访问文件。这就是为什么我在androidmanifest.xml文件中添加了提供商，然后在res＆gt; value文件夹中添加新文件provider_paths.xml。 时，我将面临错误

Launching lib/main.dart on M2010J19SI in debug mode...

androidmanifest.xml文件

</manifest>

但是现在，当我像这样运行我的 强>

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="." />
    <external-files-path name="external_files" path="." />
    <!-- FOR SD CARD-->
    <root-path name="sdcard1" path="." />
</paths>

我该如何解决这个问题？

Answer 1

1-从res＆gt;删除provider_paths.xml值

2-添加新的 xml 在res（res＆gt; xml）中的文件夹

3-在 xml （新创建的）文件夹中，添加新provider_paths.xml并粘贴此代码

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path
        name="external_files"
        path="." />
</paths> 

4-在 androidmanifest.xml

    <provider android:name="androidx.core.content.FileProvider"
        android:authorities="com.example.insurance.fileprovider"                                             
        android:exported="false"
        android:grantUriPermissions="true">

          <meta-data android:name="android.support.FILE_PROVIDER_PATHS"
              android:resource="@xml/provider_paths"/>

    </provider>

享受！
