Trouble with tun2socks (BADVPN) on android (Device Error)

i'm trying to redirect http/https traffic to a proxy server using Android Built-in VPN API and tun2socks executable file on android which compiled with NDK .
here is my code for establishing the tun0 device .

 Builder mVPNBuilder = new Builder();
            mVPNBuilder.setMtu(1500);
            mVPNBuilder.addRoute("0.0.0.0",0);
            mVPNBuilder.addAddress("25.25.25.1",32);
            mVPNBuilder.addDnsServer("8.8.8.8");
            mVPNDescriptor = mVPNBuilder.setSession("TUN2SOCKS").setConfigureIntent(pendingIntent).establish();

and this is the command which i use to run tun2socks

 cmd +=  "--netif-ipaddr 25.25.25.2 " +
                    "--netif-netmask 255.255.255.0 " +
                    "--socks-server-addr 192.168.1.200:808 " +
                    "--tunfd " + String.valueOf(mVPNDescriptor.getFd()) + " " +
                    "--tunmtu 1500 " +
                    "--logger stdout " +
                    "--loglevel 5 " +
                    "--pid /data/data/" + getPackageName() + "/tun2socks.pid";

and here is the output of the logcat
