FLEX AIR Read and write Android local files

1. Target: Save the byte stream image on the Android local path, such as "/data/mypppd/",

        File = File.documentsDirectory.resolvePath ("/data/mypppd/" +countpoint+ ". jpg");         New FileStream ();        Filestream.open (file, filemode.write);        Filestream.writebytes (Bytes[countpoint]);        Filestream.close ();

2. Target: Read the picture file display from the Android local directory (for example, to display the ad image)

If you read the picture from "/data/mypppd/", do not know in advance that there are several files in the directory, provide a solution to initialize an array, where the length is set to 7, the display of the loop in turn, encountered a non-existent direct jump to the next loop, so that you can display 0-7 pictures in turn any of the case.

A. Read the picture file locally (saved in urlreq and can be accessed via load)

　　

  New Array ();   New Array ();    for (Var j:int = 0; J < 7; J + +)  {      = "/data/mypppd/" + (j+1) + ". jpg";               = File.documentsDirectory.resolvePath (path);       New urlrequest (File[j].url);  }

　　

B. Display pictures

protectedfunction Myload ():void{IMG1=NewImage; Load=NewLoader; //Error event when a listener file does not existLoad.contentLoaderInfo.addEventListener (Ioerrorevent.io_error, Loaderrorhandler); //if (urlreq[index]! = null)//loading pictures into loadload.load (Urlreq[index]); //global variable index, control picture sequence number, initialize to 0index++; if(Index >= 7) Index= 0; //Picture Mount completion eventLoad.contentLoaderInfo.addEventListener (Event.complete, imgloaded);} //continue calling Myload () when the picture file does not exist, looking for the next onePrivatefunction Loaderrorhandler (event:ioerrorevent):void{trace (event.tostring ()); if(Index >= 7) Index= 0;            Myload ();} //calling a function after loading endsPrivatefunction imgloaded (e:event):void{    //Displays the loaded picture in an image control named pic.Pic.source=load.content; //VisibleImage.visible =true; }
