How do I get the Open Dialog on Android ICS 4.0?
Jul 2, 2012 6:46 PM
Hi,
I am using Flash CS6, Android setup, 3.0 AS
I have a Galaxy Tab, ICS 4.0 for a device
I can read & write a text file perfectly fine on my PC.
But, when I upload to my Galaxy Tab 2 (7")....
1) I get a generic dialog that displays my path (/mnt/sdcard/) ... And it also displays "Audio, Image, Video" options. It says "Download" as a diaglog title.
I can save the file perfectly fine.
2) When I try to open, it only displays the "Audio, Image, Video" options BUT DOES NOT allow me to open the file I saved.
SO, HOW DO I GET A DIALOG THAT ALLOWS ME TO BROWSE TO THE FILE I SAVED??
Here is my code...

//import flash.net.FileFilter;
public class TextEditorFlash extends Sprite
{
//Fwhilton added
//var fileToOpen:File = new File();
//var txtFilter:FileFilter = new FileFilter("Text *.txt", "*.txt");
// The currentFile opened (and saved) by the application
private var currentFile:File;
// The FileStream object used for reading and writing the currentFile
private var stream:FileStream = new FileStream();
// The default directory
private var defaultDirectory:File;
// Whether the text data has changed (and should be saved)
public var dataChanged:Boolean = false;

{
trace("TextEditor()");
defaultDirectory = File.documentsDirectory;
//Fwhilton added
//defaultDirectory = File.documentsDirectory.resolvePath("testapps/");
