One of the last minute requirements for submission to ADC2 was that the Java package name be different from the name used in the Android Market. My package originally was com.mysticlake.galacticguardian.
As you know I'm not a Java guru so I wondered what I could do that would be easy. I finally changed the 'com' to 'adc2'. Eclipse readily made the change and all was good.
Except for version control. I use Subversion. The repository lives on my laptop computer. (Then I always have everything with me.) Subversion did not care for changing the top directory name. For all my years of development experience I've not worked with version control systems except in the most rudimentary fashion. Guess I need to figure out branching and merging.
