If I understood you correctly, you're wondering if having both v4 and v7 support libraries is normal. 如果我对您的理解正确，那么您想知道同时具有v4和v7支持库是否正常。 It is perfectly normal as they have different purposes. 这是完全正常的，因为它们有不同的用途。 Basically they provide you with widgets and APIs to be used respectively in API levels 4 and 7 and beyond. 基本上，它们为您提供了分别在4级和7级以及更高级别的API中使用的小部件和API。 They also provide different interfaces. 它们还提供不同的接口。
