Qualcomm's augmented reality project, from the same site, has license information available here: https://ar.qualcomm.at/legal/license/ I'd guess FastCV will have a similar license.
That license for Android seems to suggest it includes at least the GPL. That means commercial apps built with this library must make the source available, right?
Where do you get that from? The only reference to the GPL that I noticed was in section 2.2, which expressly forbids you from doing anything which could make the code become subject to the GPL.
