问题
All the source code is included when downloading the support libraries via SDK manager in Android Studio. Now I need to fix a bug in the support v4 code and add it as a *.jar in my application. But I don't understand how I open and build the source code in Android Studio. Do I import it as a new project? Do I open it as an existing project? What directory is the directory to be imported/opened? Can I just rebuild support-v4 code into a jar?
Thanks!
