问题
I recently found out that Google introduced a new runtime in May 2016 to run Android apps on Chromebooks.
I'm already using the original ARC which was introduced a couple years ago. Unfortunately, the only way to access storage outside of the private runtime is by enabling { "enableExternalDirectory": true }, which prompts the end-user to mount a directory at startup, and then they can manually re-mount + restart as needed. This is not user-friendly.
The new Android Runtime is only supported on a limited set of devices, and requires a setting to be enabled. If I had one of those devices I would be able to test myself, but I'm hoping someone out here will already know the answer...
Can anyone confirm whether apps using the new runtime includes API access to external storage devices? For example, USB Thumb Drives? If so, this would solve the problems I've been having.
