nit: why not construct it in one line?

[Pete Williamson, 2016/11/09 23:53:55]

Done.  I didn't do it in the first place because I thought it made the code
easier to read and use in a debugger.  I realize others have different
preferences for what makes code easy to read.  We don't normally use a symbolic
debugger for our android code, so that is likely not an issue here.
