// Create a new Service object which has SystemInfo Service data
var sysInfo = new Service("Service.SysInfo", "ISysInfo");
// Define input parameters
var inParams = {Entity:"Battery", Key:"BatteryStrength"};
// Retrieve information about a system attribute with an asynchronous call
sysInfo.GetInfo(inParams,onReceive);
// Define callback function
function onReceive(transactionID:Number, eventID:String, outParam:Object) {
if (outParam.ErrorCode == 0) {
var systemData = outParam.ReturnValue;
var batteryStatus = systemData.Status;
text_txt.text = "Battery status: "+batteryStatus+"%";
} else {
var errorId = outParam.ErrorCode;
text_txt.text = "Error: "+errorId;
}
}
