Why should we do this instead of just installing each apk in active_splits?

[agrieve, 2015/05/13 15:47:46]

I'm guessing you're question is about using "adb install-multiple" vs "adb
install" for each split?
The answer is that you can't. Splits are not normal .apks, and they can only be
installed via "adb install-multiple"

[jbudorick, 2015/05/13 15:49:14]

Yeah, that was the question. Sorry, should've phrased it better.

In that case, this should not go through DeviceUtils.Install.
