Hi,

First, thank you very much for your time to read my questions. My steps are
as below:
1) I git cloned the latest web-platform-tests to my
workstation(Ubuntu16.04).
2) Downloaded the chromium source code for android(71.0.3546.0) and built
out a "ChromePublic.apk".
3) Followed the instructions in "docs/_running-tests/chrome_android.md".

Then I plugged in the usb cable to an android phone(already rooted and its
/etc/hosts has been modified like suggested), adb install the
ChromePublic.apk, then run:
"./wpt run chrome_android wake-lock" (choose wake-lock just because it
contains fewer test cases)

It failed with logs:

I see something went wrong from logs:

*"WARNING Failed to start protocol connection" and *

*"WebDriverException: Message: unknown error:
com.google.android.apps.chrome is not installed on device 00447583"*
I also downloaded a Chrome apk(version 68) from some app store and tried
again, but some error happened.
Could some experts give some hints on this? thanks very much!
