ARCore SDK for Android v1.17.0

Upcoming breaking change affecting previously published 32-bit-only apps

In August 2020, Google Play Services for AR (ARCore) will remove support
for 32-bit-only ARCore-enabled apps running on 64-bit devices. Support for
32-bit apps running on 32-bit devices is unaffected.

If you have published a 32-bit-only (armeabi-v7a) version of your
ARCore-enabled app without publishing a corresponding 64-bit (arm64-v8a)
version, you must update your app to include 64-bit native libraries before
August 2020. 32-bit-only ARCore-enabled apps that are not updated by this time
may crash when attempting to start an augmented reality (AR) session.

To learn more about this breaking change, and for instructions on how to update
your app, see https://developers.google.com/ar/64bit.
