Steps to reproduce the problem:
1. Chromedriver built from latest chromium source.
2. Example
 https://sites.google.com/a/chromium.org/chromedriver/getting-started/getting-started---android
3. After then Chrome mobile browser get all data reset.

What is the expected behavior?
I think chromedriver would keep browser app data just like chrome desktop. Maybe could we service as kind of instance by keeping browser data safe? 

What went wrong?
It always resets browser data.
