Flash Lite ActionScriptコード

コード

stop();
var talktime:Number;
 
var standbytime:Number;
device_name_txt = "N95";
 
//Get Instant Battery Check
batteryFunc();
// Monitor Battery level after certain time elapse to 
// call the function to show batter status on the screen.
// Set Interval in miliseconds
setInterval(batteryFunc, 5000); //5 Seconds        
 
//Battery func fetches the battery level and displays it on the screen
function batteryFunc(){
 
batMax = fscommand2("GetMaxBatteryLevel");
batLevel = fscommand2("GetBatteryLevel");
batSource = fscommand2("GetPowerSource");
 
//Change the battery_lvl_mc height depending on the Battery Level
_root.battery_mc.battery_lvl_mc._height = Math.ceil(batLevel*100/batMax);

バッテリー持ち時間とスタンバイ時間を決定する

バッテリー持ち時間とスタンバイ時間は、ターゲットとなる端末の仕様を取得するだけで、知ることができます。よって、簡単な数式を使って、その結果をすぐに得ることができます。

//Show Battery text
//N95 - standard talk time is 6.5 Hours and Standby time is 220 Hours
battery_Txt = "Battery Level: " add Math.ceil(batLevel*100/batMax) add "%";
Talk_time_Txt = Math.round(batLevel*390/batMax) add " mins" ; //N95 6.5 Hours
stand_by_time_Txt = Math.ceil(batLevel*220/batMax) add " hr"; //N95 220 Hours
 
//Change Display status based on battery source
if (batSource == 0) {  //On Battery
	_root.battery_mc.gotoAndStop(2);
}
//Change Display status
else if (batSource == 1) { //On Charger
	_root.battery_mc.gotoAndStop(3);
}
else { //Unknown
	_root.battery_mc.gotoAndStop(1);
}
 
}

いくつかのNokia端末における、通話時間、スタンバイ時間に関する仕様：

//Determine Device talk time and standby time based on the Phone Specifications taken from Nokia Website
statusdevice = fscommand2("GetDevice", "devicename");
switch(devicename) {
    case "Nokia N95":
        device_name_txt = "N95";
		talktime =  390; //6.5 hours    
		standbytime = 220; //220 Hours
        break;  
	case "Nokia 5300":
		device_name_txt = "5300";
		talktime =  192; //3.2 hours    
		standbytime = 223; //220 Hours
        break;  
	case "Nokia 6290":
		device_name_txt = "6290";
		talktime =  210; //3.5 hours    
		standbytime = 260; //260 Hours
        break; 
	case "Nokia 6300":
		device_name_txt = "6300";
		talktime =  210; //3.5 hours    
		standbytime = 348; //348 Hours
        break; 
	case "Nokia 7390":
		device_name_txt = "7390";
		talktime =  190; //3 hours    
		standbytime = 220; //220 Hours
        break; 	
	case "Nokia 3250":
		device_name_txt = "3250";
		talktime =  210; //3.5 hours    
		standbytime = 245; //245 Hours
        break; 		
}
