我的flutter項目升級到最新版本后出現AndroidManifest.xml錯誤

Question

這是在完成此處的步驟之后

按照上述步驟“解析 LocalFile 時出錯：'/home/user/Projects/xylophone-flutter/android/app/src/main/AndroidManifest.xml' 請確保 android 清單是有效的 XML 文檔后，我一直收到此錯誤然后再試一次。”

我使用的是最新的音頻播放器dart package，需要升級。 按照文檔中的步驟操作后，我偶然發現了這個錯誤。 我已經完成並檢查了我的語法，我的 IDE 沒有顯示任何問題區域。 我不確定我錯過了什么。 非常感謝任何幫助或反饋。

這是我的 AndroidManifest.xml 代碼：`

<!-- The INTERNET permission is required for development. Specifically,
     flutter needs it to communicate with the running application
     to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET"/>

<!-- io.flutter.app.FlutterApplication is an android.app.Application that
     calls FlutterMain.startInitialization(this); in its onCreate method.
     In most cases you can leave this as-is, but you if you want to provide
     additional functionality it is fine to subclass or reimplement
     FlutterApplication and put your custom class here. -->
<application>
</application>
    <activity
        android:name="io.flutter.embedding.android.FlutterActivity"

        android:windowSoftInputMode="adjustResize">
        <!-- This keeps the window background of the activity showing
             until Flutter renders its first frame. It can be removed if
             there is no splash screen (such as the default splash screen
             defined in @style/LaunchTheme). -->
        <meta-data
            android:name="flutterEmbedding"/>
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
</application
