This in form of a gist, is the raw checkstyle checks for android coding conventions I am starting with. Obviously, its for checkstyle 5.6.0 and it has not been tweaked yet as far as android coding conventions. But, its close and I will update with changes.
The big change, from other of my checkstyle for android files that you may have used is that no suppressions.xml file is used but instead we use comment delimiters to turn on and off checkstyle checks within the source code. Makes code maintenance a whole lot easier.
