我最近正在构建一个Flutter项目。我可以在iOS模拟器上运行它，但不能在Android模拟器上运行。当我试图在Android上运行它时，出现了以下错误：
失败：生成失败，出现异常.

• 问题：执行任务“：app：processDebugManifest”失败。

合并失败异常：发生异常;行号：9;列号：2;文档中根元素后面的标记必须格式正确。
AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.Meucci">
    <!-- 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"/>
</manifest>

<application tools:node="replace">

</application>

Build.gradle

def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

}

flutter {

gradle.properties

有谁能帮忙吗？非常感谢。
