thanks for noticing. As I said there is no problem in other devices even other androids which use same "openvpn connect".
So there is no problem with Server/client config.
I used "netstat" command in my android 5.0.1 and I get some amazing results:

As you can see, some connections doesn't go through vpn!!
Do you have any solutions?
