我今天开始用AndroidStudio编程，一个朋友给我发了一个小的示例应用程序，但我无法运行任何代码，因为这个错误不断出现。我已经尝试解决它约3个小时，现在与不同的论坛，但我不能让它工作，我会非常感谢您的帮助，因为我只是不知道该怎么做....
控制台：

android:exported needs to be explicitly specified for element <activity#com.dbestech.food_delivery.MainActivity>. 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.
