When I run "./run_benchmark --browser=android-jb-system-chrome blink_perf.svg" on Nexus5(it's a rooted device with user binary) on Linux, I get an error message "No URLs matched: gs://chromium-telemetry/binary_dependencies/forwarder_host_b3dda9fbdd4a3fb933b64111c11070aa809c7ed4". Chrome on Android will open an "about:blank" page.
