Google Map Not Show Correctly

I have an Google Map apikey, i use it in googlemap sample project. It is working if the project run in browser, but when i install apk (via phonegap build) in my mobile, the map wont show “google map is not able to show correctly”

What is wrong ?

Thanks

My first guess is it’s with your content security policy.

Connect the Chrome Remote Debugger while your apk is running. There should be an error message which tells you the problem. (CSP is a good possibility!)

it is worked after I set CSP to ‘none’

Thanks
