当我从 Maven 向项目添加 lib 时。 如何找出我可以使用的课程？

Question

Documentation of said library says to import a specific class, and different one for older versions.

I tried both and none are recognized by android studio as exisiting.

How do I find out if an mavenCentral() library has been downloaded and included to my android project??

How do I find out if an mavenCentral() library has been downloaded and included to my android project?

If you added the appropriate line to your module's Gradle build script (eg, implementation ... ), it should be there, or you would have gotten a build error complaining about not being able to download the artifact.

You can see what libraries are available to your overall project in Android Studio by first switching the project tree from the Android view to the Project view via the drop-down above the tree:

If you scroll down in the tree, you will find a "External Libraries" branch of the tree that you can expand:

This lists all of the libraries available to the whole project, including those from tests, transitive dependencies, etc.
