InheritanceFileChooser Inheritance flash.events.EventDispatcher

FileChooser is a very easy to work extension to let you choose a file from your sdcard to be able to use it inside your Air project. you can use the choose method and pass the type of file you need by passing its mimetype. */* for example means any file in any extension! but image/* means any image file while image/png means any png image file.

Also remember to add the following activity to your air .xml manifest: 

<activity android:name="com.doitflash.fileBrowser.Chooser" android:theme="@style/Theme.Transparent" />

Make sure to take care of the permissions manually if you are targeting AIR SDK 24+: https://github.com/myflashlab/fileChooser-ANE/#permissions

public function choose($type:String, $title:String, $imageResizeOptions:Object = null):void

use this method to start an activity to let you pic a file type you specify.

$type:String — mimetype for the file you want to select
 
$title:String — title of the file picker dialog shown on some Android versions only
 
$imageResizeOptions:Object (default = null) — image resize object must look like this: {width:500, height:500, quality:50}


Example
This example shows how to select an image and also resize it. 
         import com.myflashlab.air.extensions.fileChooser.FileChooser
         import com.myflashlab.air.extensions.fileChooser.FileChooserEvent;
         
         var _ex:FileChooser = new FileChooser();
         _ex.addEventListener(FileChooserEvent.RESULT, onResult);
         _ex.addEventListener(FileChooserEvent.ERROR, onError);
         
         _ex.choose("image/*", "pick an image!", {width:500, height:500, quality:50});
         
         function onResult(e:FileChooserEvent):void
         {
             var originalFile:File = e.param.original;
             
             trace("original file.name = " + originalFile.name);
             trace("original file.extension = " + originalFile.extension);
             trace("original file.size = " + FileSizeConvertor.size(originalFile.size));
             trace("");
             
             // e.param.resized is only available if you are picking an image and have specified the resize object for it.
             var resizedFile:File = e.param.resized;
             if (resizedFile) 
             {
