我可以在一个项目中使用2个清单吗？

Question

我可以在一个项目中制作第二个清单文件，但没有android:icon和android:label ，因此用户只能看到一个应用程序吗？

Answer 1

An app module will have one manifest file; you cannot have a second.

Libraries that contribute to the app may have their own manifest files. However, the contents of those manifests get merged with the app's manifest and other data sources (eg, Gradle). In the end, your app still winds up with one manifest, with one <manifest> element and one <application> element.

In the future, you will get better results on Stack Overflow if you explain in your question what the real problem is (in this case, what you think having a second manifest will do for you). For example, if the reason you want two manifests is because you want two <application> elements, because you are trying to use two custom Application subclasses, that is not possible. You would need to arrange to have one Application subclass that provides all the functionality.

Answer 2

the user does not see the app in the launcher, they see the launcher activity. If you have more than one launcher activity they all appear in the launcher.
