错误：覆盖清单：AndroidManifest.xml:2:5-34 中声明的包属性。扑

Question

简单的问题，\n很难解决（我认为），

\n

当我启动 main.dart 时出现此错误：

\n

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

\n

这是我的 build.gradle：

\n

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

\n

这是我的 AndroidManifest.xml：

\n

package="com.example.Scanner">\n

\n

我希望有人可以帮助我，否则我就不能再在这个应用程序中\xc2\xb4t编程了:(

\n

移除后package="com.example.Scanner"我收到此错误：

\n

Answer 1

我遇到了同样的问题，我在 5 个位置更改了包名称。

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

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

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

4. 构建gradle文件defaultConfig { applicationId ""}

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

修改上述文件后，Flutter App运行没有任何问题。

Answer 2

我也遇到了同样的问题，但经过以下步骤后我明白了我的意思；

您的包名称“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.MainActivity.java关于“包裹”或MainActivity.kotlin

就我而言，我的包名称是 com.example.blog_daily。因此，我在所有点上重写了所有同名的包并解决了我的问题。
