Problem with AndroidManifest.xml file in flutter-CodePudding

I'm new to Android development, and I am trying to get familiar with it with some tutorials. Currently, I am stuck with this so could you please guide me through this? I have an issue with my AndroidManifest.xml file when I try to run it in debug. I added the trace of the error below along with the xml file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.ebook"
    android:versionCode="1000"
          android:versionName="1.0.0">
   

   <application
        android:name="${applicationName}"
        android:name="android.support.multidex.MultiDexApplication"
        android:icon="@mipmap/ic_launcher">

        <activity
        
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that, this theme continues
                 to determine the Window background behind the Flutter UI. -->

            </intent-filter>
        </activity>

            android:value="2" />
    </application>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    

    
</manifest>

CodePudding user response：

You have the same attribute two times:

   <application
        android:name="${applicationName}"
        android:name="android.support.multidex.MultiDexApplication"

I suppose you want to create multidex application (to overcome 64K methods limit), so you should remove android:name="${applicationName}". See https://developer.android.com/studio/build/multidex.

CodePudding user response：

Mistake is you added duplication line

        android:name="${applicationName}" (A)
        android:name="android.support.multidex.MultiDexApplication"(B)

if you want your app support multidex - Keep A, let yourApplication class extend MultiDexApplication - then remove (B)
