错误：覆盖清单：package 在 AndroidManifest.xml:2:5-34 声明的属性。 Flutter

Question

简单的问题，很难解决（我认为），

当我启动 main.dart 时出现此错误：

Error:
    Overlay manifest:package attribute declared at AndroidManifest.xml:2:5-34 value=(com.example.Scanner)
    has a different value=(com.example.Scanner) declared in main manifest at AndroidManifest.xml:1:70-97
    Suggestion: remove the overlay declaration at AndroidManifest.xml   and place it in the build.gradle:
        flavorName {
            applicationId = "com.example.Scanner"
        }

FAILURE: Build failed with an exception.

这是我的 build.gradle：

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId="com.example.Scanner"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

这是我的 AndroidManifest.xml：

package="com.example.Scanner">

我希望有人能帮助我，否则我不能再在这个应用程序上编程了:(

删除package="com.example.Scanner"后出现此错误：

从 androidmanifest 中删除 package 属性并检查

我完成了一个错误。 然后我得到一个新的 java 错误。 我只将 AndroidManifest.xml 从旧项目复制到新项目，并且它有效。 这对我有用：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.Scanner">
    <!-- 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
        android:name="io.flutter.app.FlutterApplication"
        android:label="Scanner"
        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. -->
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <!-- Displays an Android View that continues showing the launch screen
                 Drawable until Flutter paints its first frame, then this splash
                 screen fades out. A splash screen is useful to avoid any visual
                 gap between the end of Android's launch screen and the painting of
                 Flutter's first frame. -->
            <meta-data
              android:name="io.flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
</manifest>

，但我不知道出了什么问题。 我从来没有改变过它。 只需更改package="com.example.YOURNAME">和android:label="YOURNAME"

Answer 2

我也有同样的问题，但在完成以下步骤后我明白了我的意思；

您的 package 名称“com.example.com”（在您的情况下可能不同）在 5 个位置应该相同，例如

1. android/app/src/debug/AndroidManifest.xml

2. android/app/src/main/AndroidManifest.xml

3. android/app/src/profile/AdroidManifest.xml

4. buildgradle文件defaultConfig { applicationId ""}

5.“包”上的MainActivity.java或MainActivity.kotlin

在我的例子中，我的 package 名称是 com.example.blog_daily。 所以我在所有点重写了所有同名的包并解决了我的问题。

Answer 3

首先使所有 package 名称相同//要执行此操作，在终端中显示的搜索栏中搜索您的 package 名称并修复它们//然后运行 Z5ACEBC4CB70DDBB074B0AC76AAB176AEDDBB07ZBAC76CB701DDAE7ZBAC76CB701 现在您可以运行 flutter 运行。 我认为它会解决你的问题。

Answer 4

你好，

我遇到了同样的问题，我在 5 个位置更改了 package 名称。

1.) android/app/src/debug/AndroidManifest.xml

2.) android/app/src/main/AndroidManifest.xml

3.) android/app/src/profile/AdroidManifest.xml

4.) buildgradle 文件 defaultConfig { applicationId ""}

5.) MainActivity.java on "package" OR MainActivity.kotlin

修改上述文件后，Flutter App运行没有任何问题。
