Summary: The general practice of creating a third-party library in the form of a module is:

(1) Create a module in the form of a library and delete all the files in the src/main directory in the module (including deleting java, res, AndroidManifest.xml)

(2) Copy the AndroidMainfest.xml, res, and src files (folders) of the third-party library to the src/main directory of the library directory

(3) Rename (Shift+F6) the src directory under the src/main directory to java
