如何在IntelliJ项目中添加新的Android API / SDK？

Question

How do I add a new Android API to my IntelliJ project? I'm trying to add 20 and 21 to my Android project. In the Project Structure view, when I select SDKs in the leftmost list view, I see API 7 - 19 along with the JDK. When I use the plus (+) button, it allows me to scroll to the place where the SDK Manager apparently downloaded the latests SDKs, and I can browse and find (under the sources folder) android-20 and android-21 folders right along with all the others. But when I select one of them and then click the "Choose" button, nothing gets added. Inconceivable. Here's what my Project Structure view looks like:

And below is a pic of the contents of my Android SDK folder, although apparently the SDK Manager downloads specific API SDKs into the sources folder. In it I have SDKs 7 - 21 now.

You should not select the subfolders, but rather the top-level SDK folder. Once you do this a dialog will be displayed showing all detected versions in that SDK structure, which you can then select to add.
