Source

// Import Platform Service Interface
import com.nokia.lib.Service;

// Heading of the application
heading_txt.text = "Checking Memory card existence";
 
// Create new Service object which has SystemInfo Service data
var sysInfo = new Service("Service.SysInfo", "ISysInfo");
 
// Define input parameters
var inParams = {Entity:"Memory", Key:"MemoryCard"};
 
// Retrieve information about a system attribute with a synchronous call
// Define result value
var outParams = sysInfo.GetInfo(inParams);
if (outParams.ErrorCode == 0) {
	var systemData = outParams.ReturnValue;
	var memoryCard = systemData.Status;
	if(memoryCard == 1) {
		text_txt.text = "Memory Card: Enabled";
	} else {
		text_txt.text = "Memory Card: Disabled";
	}
} else {
	var errorId = outParam.ErrorCode;
	text_txt.text = "Error: "+errorId;
}text_txt.text = "Error: "+errorId;
}
