hmm. Looks like there are two kinds of StrictMode violation.
The other is disk read violation which due to GVR moved API initialization in Gvr ctor.

The stack looks something like this:

Comment 3 by bshe@chromium.org, Dec 12 2016

Status: Fixed (was: Started)
So strict mode violation mentioned in #0 is because of VrCore. Somehow VrCore's version of ContentProviderVrParamsProvider is invoked. Update VrCore to a new version fixed the Strict mode violation. So mark this as fixed.
