Methods should take/return List, Map, etc. instead of ArrayList, HashMap, etc. about omnidroid HOT 3 CLOSED

Hi Kai,

According to the following link, it is advisable to do just this for 
performance 
reason unless we are working on public API.

ual

I don't know if you think above would be considered a public API but just 
wanted to 
point out why original developers might have selected the given route.

Ah, well that pretty much settles it. Thanks for pointing that out. We should
probably link to any Android-specific best practices we expect code to follow 
for use
in code reviews.

If no one has any objections, I'll close out this issue as "won't fix."
