部署成功，但应用程序未在模拟器上运行

Question

我正在使用 VS 2019 和 Android SDK API 30。

Android 应用程序的部署成功消息显示在输出窗口中，但在模拟器上看不到该应用程序。

输出日志如下： 输出日志：

Answer 1

我在运行应用程序时没有收到任何错误，APK 已成功构建，没有错误，但它没有部署到设备或模拟器。当我通过scrcpy（屏幕镜像工具）手动安装APK时，出现错误：INSTALL_PARSE_FAILED_NO_CERTIFICATES。

基本上，在我的 Android 构建设置中，我错误地将程序集名称从 ProjectName.Android 更改为 ProjectName。

在 Android Build 设置中，在 Application 选项卡下将 Assembly Name 设置为 ProjectName.Android。
