How should I obtain the ip address of default gateway ? Rather than read entries from /proc , is there any standalone API useable ? you can use libnl which is a library to communicate with the kernel via NETLINK sockets. a simple example to get the default route would be (please add error checking and the needed headers) void cb_route (struct nl_object *cb, void *arg) { struct rtnl_route *route = (struct rtnl_route*) cb; /* do what you need to do with rtnl_route object * e.g. copy it to arg, etc. */ struct nl_addr *tmp_addr; tmp_addr = rtnl_route_get_gateway(route); len = nl_addr_get_len(tmp

In my android application, I use a listview and some linear layout on wich the user can click. Of course, I had to set the background of my LinearLayout to a xml file where the stated pressed, selected are defined: myView.setBackgroundDrawable( getDrawable(android.R.drawable.list_selector_background)); So no problem I set the drawable to transparent when normal use and orange when clicked. My only problem is that on the galaxy S and some other customized phone (Sense UI) the color of the listview clicked is blue or green! So I need to pick this color to set it to the background of my

Have a source xml document that uses namespace containing prefixes and a default namespace. When I transform it using a XSLT doc, the resulting translated xml document is incorrect, that is, element data from the source xml document is missing. When I remove the "default namespace" from the source xml document, the transformation works as expected. Question: is there a way to resolve problem without the need to edit out the default namespace from the source xml document? That is, add the solution to the XSLT document. XML Document: <MyElement xmlns:xsi="http://www.w3.org/2001/XMLSchema

I use this myButton.setBackground(myColor) to change the JButton background color to my color, how to find it's original default background color so I can change it back? I know I can save its default background color before I change and use that, but I wonder if Java stores it somewhere so that maybe I can call something like: myButton.getClass.getDefaultBackground() to get it back ? btn.setBackground(new JButton().getBackground()); how about this... it will get the default color of button myButton.setBackground(null) changes it back to the default color. This might help: http://java.sun.com
