I'm not sure how well this combines with the apk_path positional arg. A user is
basically forced to pass the base apk as the apk_path, then pass the --splits.

Changed this argument back to use action='append'
Run something like...
adb_install_apk.py base_apk.apk --split base_apk*.apk
or 
adb_install_apk.py base_apk.apk --split base_apk*.apk --split othersplit.apk

Is there any way we can detect which apk of a list of apks is the base APK?
(preferably w/o using the names)

[agrieve, 2015/06/26 23:53:03]

It'll be the only one without a split="foo" attribute on it's root <manifest>
tag.

[mikecase (-- gone --), 2015/06/27 00:21:22]

If you're going to pass in a glob like Chrome*.apk to match the splits like you
suggested, its going to match both things like
Chrome.apk, ChromeShell.apk, and ChromePublic.apk. There really isn't a way to
know which apk you actually want
to install without passing the base_apk in separately.

[jbudorick, 2015/06/29 15:49:01]

Hmm, right.
