android - 即使targeSdkVersoin的版本与24相同，Gradle appcompat-v7也会出现错误？

Question

该应用在我构建时就可以运行，并且运行良好。但是我想解决这个问题，因为将来可能会引起问题。图片显示了当我将鼠标悬停在上面时的错误。有关如何解决此问题的任何建议？

我对为什么找到两个版本24.2.1和24.0.0感到困惑，这是为什么呢？哪个版本合适？

谢谢

我在终端上运行gradlew app:dependencies并发现了这一点，
如果您查看该botton，并找到以下com.android.support:appcompat-v7:24.0.0(在底部):

如果我遵循它的根目录并找到了com.android.support:mediarouter-v7:24.0.0，那么我将其添加到依赖项中并将其更改为compile com.android.support:mediarouter-v7:24.2.1，错误现在消失了。这是正确的做法吗？顺便说一句，我运行我的应用程序，并且没有错误(即使gradle中有错误，该应用程序仍在运行)。

谢谢

Answer 1

And I'm confused as to why it found two version 24.2.1 and 24.0.0,

您必须使用gradlew app:dependencies。

这样，您将发现哪些库具有24.2.1和24.0.0的依赖关系
