How to enforce webkit to use system APN proxy in Android?

I'm trying to force Webkit to use proxy definde in APN.

My pr开发者_如何学Gooxy configuration:

APN: wap
PROXY: 192.168.6.102
PORT: 8080
USER: wap
PASSWORD: wap`

Currently all connections made by Webkit are blocked on firewall. Is there way to use proxy from phone profile?

Seems there are bugs in Android preventing this
