Crosswalk without the file custom_rule.xml

I’ve created project in Ionic and added it on android platform. Next I used the rules from “custom_rules.xml” where I changed the name as in Override automaticlly generated app_name for android

Unfortunetly, when I add broswer Crosswalk, the file “custom_rules.xml” disappears.

How can I use rules from “custom_rules.xml” if this file doesn’t exist anymore?
