com.android.manifmerger.ManifestMerger2$MergeFailureException

Question

I am recently building a Flutter Project. I can run it on iOS simulator but not in Android emulator. When I tried to run it on Android, here is the error:

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:processDebugManifest'.

com.android.manifmerger.ManifestMerger2$MergeFailureException: org.xml.sax.SAXParseException; lineNumber: 9; columnNumber: 2; The markup in the document following the root element must be well-formed.

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 localProperties = new Properties()
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'
}

Anyone can help? Thx so much.
