错误：当前项目不支持运行配置应用程序。无法获取应用ID答案

【问题标题】：Error: Run configuration app is not supported in the current project. Cannot obtain the application ID错误：当前项目不支持运行配置应用程序。无法获取应用ID

【问题描述】：

每次我在 Android Studio 中打开我的项目时，都会出现这个错误：

Error: Run configuration app is not supported in the current project. Cannot obtain the application ID.

当我点击Sync project with Gradle Files，在同步过程之后，这个错误消失了。然而当我重新打开项目或重新启动 Android Studio 时，再次出现此错误。

我知道Sync project with Gradle Files 可以做到这一点，但我不想每次打开我的项目时都这样做，我试图降级 Android Studio，但它似乎不起作用。

我的环境：

Android Studio 海豚 | 2021.3.1
Gradle 7.5.1
Android Gradle 插件 7.3.0

有趣的是，每次我启动 Android Studio 时，都会弹出一个 IDE 错误：

我依赖于我自己编写的另一个私有模块设置.gradle

includeBuild('external/xxxx-xxxx') {
    name "xxxx-xxxx"
    dependencySubstitution {
        substitute module('com.xxxx.xxxx:xxxx:1.0.0') using project(':xxxx-xxxx')
    }
}

也许是我的子模块的问题或 Android Studio/Gradle 中的错误？其他项目没有这个问题。

【解决方案1】：

就我而言，Manifest 文件中缺少包名称（很奇怪，因为我刚刚创建了项目，并且默认情况下它应该存在）但我添加了它，现在它可以工作了。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"package="com.example.name">
