首先，这不是重复的。

我已将模拟器版本和 android SDK 版本更新为 Android S (Android 12) 但更新后。我无法运行该项目。我无法运行 hello world 项目（空项目）。但是我可以构建成绩，但不能运行该项目。我总是收到错误：

***Manifest merger failed: Apps targeting Android 12 and higher are required to specify an explicit value for `android: exported` when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.***

请任何人都可以帮助我吗？

这是一个截图...

升级到 android 12 后，应用程序未编译。表明

“清单合并因多个错误而失败，请参阅日志”

合并清单中显示的错误：

合并错误：错误：android:exported 需要为 明确指定。面向 Android 12 及更高版本的应用需要为android:exported相应组件定义了意图过滤器时指定显式值。有关详细信息，请参阅 https://developer.android.com/guide/topics/manifest/activity-element#exported。主清单（此文件）

我已将所有活动设置为android:exported="false". 但它仍然显示这个问题。
