1、? Air如何判斷android、ios 平臺網絡連接狀態？

Android，使用as3原生api：

?

[javascript]?view plaincopy

if(NetworkInfo.isSupported)//只有android支持??

??

????????????????NetworkInfo.networkInfo.addEventListener(Event.NETWORK_CHANGE,onNetWorkChanged);??????????

????????????????onNetWorkChanged();??

???????}??

rivate?function?onNetWorkChanged(e:Event?=?null):void??

???????{????????????????????????????

????????????????var?isActived:Boolean?=false;??

?????????????????

????????????????varinterfaces:Vector.<NetworkInterface>?=NetworkInfo.networkInfo.findInterfaces();??

?????????????????

????????????????varnetInterface:NetworkInterface;??

????????????????for?(?var?i:int?=?0,?len:int=?interfaces.length;?i?<?len;?i++)??

????????????????{??

?????????????????????????netInterface?=interfaces[i];??

?????????????????????????if(netInterface.name.toLowerCase()==?"wifi"?&&?netInterface.active)?{??

???????????????????????????????????isActived=?true;??

???????????????????????????????????break;??

?????????????????????????}?elseif(netInterface.name.toLowerCase()?==?"mobile"?&&netInterface.active)?{??

???????????????????????????????????isActived=?true;??

???????????????????????????????????break;??

?????????????????????????}??

????????????????}??

????????????????PhoneConfig.isOpenNet?=isActived;??

?????????????????

????????????????if(isActived?==?false)??

????????????????{??

?????????????????????????MsgManager.show("當前網絡不可用，請檢查你的網絡設置。");??

????????????????}??

???????}??

? ? ? ? ? ?Ios平臺，需要引入獨立開發的ane擴展和類庫，判斷核心代碼：

?

?

[javascript]?view plaincopy

if(netInterface.name.toLowerCase()==?"en0"?&&?netInterface.active)?{//wifi??

????????????????isActived=?true;??

????????????????break;??

????????????}else?if(netInterface.name.toLowerCase()==?"pdp_ip0"?&&?netInterface.active)?{//gprs??

????????????????isActived=?true;??

????????????????break;??

?????????}??

2、? iphone 5讀不到正確尺寸問題

ios平臺讀取stageWidth和stageHeight方法和普通的air方法一致，但iphone5出現讀取不正確的情況。

解決方法：需要根目錄放一張名為Default-568h@2x.png尺寸為640*1136的圖片，并且打包進去。

詳情見http://zengrong.net/post/1752.htm#more-1752

?

3、? ios平臺運行 release版本中途卡住問題

同一個文件 加載到當前域 加載第二次時 就會卡住（ipa調試版正常，release版就有問題；androidapk不論是調試版還是release都正常）

?

4、? 打包ipa失敗，提示無效的文件：

打包ipa時，如果文件里面有一個不正確格式的swf，打包必定失敗；如果把swf換成其他不常用文件名，即可解決。

?

5、? android、ios平臺最小化、關閉電源時app的檢測和處理方式

手機測試結果：

1）android中 按home鍵或電源鍵都是使程序后臺運行，socket不斷。

2）ios中按home鍵是使程序后臺運行，socket不斷，按電源鍵程序后臺運行，但socket斷。

通過事件ACTIVATE、DEACTIVATE來進行代碼邏輯控制

NativeApplication.nativeApplication.addEventListener(Event.ACTIVATE,onActivate);

NativeApplication.nativeApplication.addEventListener(Event.DEACTIVATE,onDeactivate);

?

6、? android、ios上文件存儲方法

核心代碼：

?

[javascript]?view plaincopy

????this.saveSDCardFile(File.applicationStorageDirectory.url+?"/aa.swf",?btye);??

(this.getSDCardFile(File.applicationStorageDirectory.url?+?"/aa.swf");??

/**?

?????????*?讀取sd卡文件?

?????????*/??

????????private?functiongetSDCardFile(url:String):ByteArray??

????????{??

????????????var?file:File?=File.applicationStorageDirectory.resolvePath(url);??

????????????if(file.exists?==?false)??

????????????????return?null;??

?????????????

????????????var?stream:FileStream?=?new?FileStream();??

????????????stream.open(file,FileMode.READ);??

????????????var?bytes:ByteArray?=?new?ByteArray;??

????????????stream.readBytes(bytes,0,?stream.bytesAvailable);??

????????????stream.close();??

????????????return?bytes;??

????????}??

????????/**?

?????????*?往sd卡上存儲文件?

?????????*/??

????????private?functionsaveSDCardFile(url:String,?bytes:ByteArray):void??

????????{??

????????????var?file:File?=File.applicationStorageDirectory.resolvePath(url);??

????????????var?stream:FileStream?=?new?FileStream();??

????????????stream.open(file,FileMode.WRITE);??

????????????stream.writeBytes(bytes);??

?????????????

????????????stream.close();??

?????}??

注意android和ios上一些目錄路徑不一樣

?

[javascript]?view plaincopy

????trace(?File.applicationDirectory.url);//App:/?（/data/data/app.appId/app/assets）??

????????????????????trace(File.applicationStorageDirectory.url);//|app-storage:/?（/data/data/app.appID/appID/LocalStore）??

????????????????????trace(File.documentsDirectory.url);??

????????????????????trace(File.userDirectory.url);??

????????????????????trace(File.desktopDirectory.url);??

????????????????????trace(File.createTempDirectory().url);//data/data/app.appId/cache??

????????????????????//android：??

//??????????????????app:/??

//??????????????????app-storage:/??

//??????????????????file:///storage/sdcard0??

//??????????????????file:///storage/sdcard0??

//??????????????????file:///storage/sdcard0??

//??????????????????file:///data/data/air.TestLoad.debug/cache/FlashTmp.u15893??

????????????????????//ios：??

//??????????????????app:/??

//??????????????????app-storage:/??

//??????????????????file:///var/mobile/Applications/EBFEE682-C347-4BC1-9264-6E4B65F4D2BA/Documents??

//??????????????????file:///var/mobile/Applications/EBFEE682-C347-4BC1-9264-6E4B65F4D2BA??

//??????????????????file:///var/mobile/Applications/EBFEE682-C347-4BC1-9264-6E4B65F4D2BA/Desktop??

//??????????????????file:///private/var/mobile/Applications/EBFEE682-C347-4BC1-9264-6E4B65F4D2BA/tmp/FlashTmp.bDIE2x??

7、? 游戲過程中的待機處理，比如在激烈pk中不允許手機進入睡眠狀態：

通過設置NativeApplication.nativeApplication.systemIdleMode屬性

?

[javascript]?view plaincopy

/**?

?????????*?是否關閉?休眠模式?

?????????*?@param?value?

?????????*/??

????????public?functionkeepAwake(value:Boolean):void??

????????{??

????????????if(value)??

????????????????NativeApplication.nativeApplication.systemIdleMode=?SystemIdleMode.KEEP_AWAKE;??

????????????else??

????????????????NativeApplication.nativeApplication.systemIdleMode=?SystemIdleMode.NORMAL?;??

????????}??

?

?

8、? 如何讀取air的app配置文件？如何讀取里面的版本號？

?

[javascript]?view plaincopy

//版本號??

public?function?get?version():String??

????????{??

????????????var?appDescriptor:XML?=NativeApplication.nativeApplication.applicationDescriptor;//配置文件??

????????????var?ns:Namespace?=appDescriptor.namespace();??

????????????return?""?+appDescriptor.ns::versionNumber;??

????????}??

?

9、? 統計流量功能（未找到as3原生api支持，可通過第三方ane擴展實現）

?

10、手機加載大文件解壓縮很慢，卡住問題（暫無較好的規避方法）

?

11、 ?檢測鼠標按下菜單鍵、及其他鍵的方法及響應

?

[javascript]?view plaincopy

NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN,this.keyHandler);??

private?function?keyHandler(e:KeyboardEvent):void??

???????????????????{??

????????????????????????????if(e.keyCode==Keyboard.BACK)??

????????????????????????????{??

?????????????????????????????????????e.preventDefault();??//取消返回鍵的退出事件??

??????????????????????????????????????

?????????????????????????????????????ExitPane.instance.show();??

????????????????????????????}??

????????????????????????????elseif(e.keyCode==?Keyboard.MENU)??

????????????????????????????{??

?????????????????????????????????????this.times++;??

?????????????????????????????????????if(times>=?5)??

???????????????????????????????????????????????ClientConfig.webDebug=?true;??

????????????????????????????}??

????????????????????????????elseif(e.keyCode?==?Keyboard.SEARCH)??

????????????????????????????{??

??????????????????????????????????????

????????????????????????????}??

????????????????????????????else??if?(e.keyCode?==?Keyboard.HOME)?{??

?????????????????????????????????????//Handle?Home?button.??

????????????????????????????}??

???????????????????}??

?

12、? 手機調試不方便怎么辦？設置手機代理，把ip指向電腦，這樣所有數據包就會通過電腦發送和接受，用電腦抓包調試。

?

13、? 其他知識點：

運行ios發行版ipa特有問題：

1）uint和int的比較：int類型的-1大于uint類型的0；

2）String(null) 依舊是null值，而不是字符串的"null"

?

NativeApplication 的exit() 方法不會導致調度exiting 事件；

android中任務管理器中結束應用也不會派發exit事件，ios中未知

ios下通過任務管理器關閉app，app本身無法控制退出

??

flash builder 編譯提示錯誤：Erroroccurred while packaging the application: Map failed

解決辦法：一般清理一下項目就ok了

?

stage.displayState =StageDisplayState.FULL_SCREEN

設置全屏后立刻讀取stagewidth和stageheight是不準確的，需要延時到下一幀再讀取
