Flutter应用在Galaxy设备安装时出现双图标问题求助

我通过Android Studio在Galaxy设备上运行Flutter创建的应用时，安装后会生成两个应用图标。我怀疑是AndroidManifest.xml或build.gradle文件存在错误，但无法定位问题所在。有人说intent-filter代码位置异常可能导致该问题，但我检查后排除了这种情况，同时也排查了debug版本的AndroidManifest文件，未发现问题。以下是我的AndroidManifest.xml和build.gradle文件内容：

AndroidManifest.xml #

1. 检查合并后的Manifest文件 #

主Manifest可能没问题，但Flutter插件会自动合并配置，可能新增带LAUNCHER过滤的Activity：

• 切换到Android Studio的Project视图
• 导航到app/build/intermediates/merged_manifests/，找到对应build类型（debug/release）的AndroidManifest.xml
• 搜索intent.category.LAUNCHER，确认是否存在多个Activity包含该规则

2. 排查图标资源重复 #

• 检查res/mipmap-*目录，确认没有多个图标资源被配置为启动图标
• 确保所有组件的android:icon指向同一资源，没有其他组件用不同图标同时标记为LAUNCHER

3. 清理缓存并重建项目 #

• 执行Build > Clean Project清理缓存
• 执行Build > Rebuild Project重新编译
• 卸载设备上的旧应用后重新安装

4. 排查第三方插件影响 #

暂时移除所有第三方Flutter插件，重新运行应用。如果双图标消失，逐个添加插件排查是哪个插件导致的异常配置。

5. 检查Product Flavor配置 #

如果项目使用了多渠道打包，确认不同flavor的配置没有重复生成启动图标或Activity配置
