I have a little problem here.. The code itself dosen´t get any errors, but it will not write to the .txt file... Hope someone can help me with this problem.
Here is my code:
test_btn.addEventListener(MouseEvent.CLICK, leggtil);
function leggtil(e:MouseEvent) {
var file:File = File.documentsDirectory.resolvePath("test.txt");
var fileStream = new FileStream();
fileStream.open(file, FileMode.WRITE);
var outputString:String = "test";
fileStream.writeUTFBytes(outputString);
fileStream.close();
}
I tested the code and it worked on my machine.
I believe that the code is working for you, but you're not aware of where the file has been written. Check your documents folder. In Windows, this would be C:\Users\[your user name]\Documents\. If you browse to that folder, you should see a file there named test.txt.

In AIR there is the File.createTempFile() method docs.
Is there a way to change the extension?
Code so far:
var webpage:File = File.createTempFile();
webpage.extension = "html"; // Property is read-only
The simple answer is: no.
You're even not able to set the filename by yourself. As soon as you call File.createTempFile(); it will create a file like fla8121.tmp which is composed of the prefix 'fla' a random 4-digit hex number and finally the '.tmp' file extension.
On windows this file will be created in C:\Users\[Username]\AppData\Local\Temp\
If you want to create a temporary file on your own, you need to do it like this:
var file:File = File.cacheDirectory.resolvePath("test.html");
var stream:FileStream = new FileStream();
stream.open(file, FileMode.WRITE);
stream.writeUTFBytes("<html>This is a test</html>");
stream.close();
This will create test.html in the same directory as createTempFile()
Im building a Test Maker App. I need some help on loading files in Android mobile. The type i want is the type where the user can look for his file from a file browser. This is the code i have so far but it wont work. My mobile always says "No files were found".
var file = File.applicationStorageDirectory.resolvePath("saved projects");//This is a folder
file.browseForOpen("Open Your File", [new FileFilter("Text Files", "*.txt")]);
file.addEventListener(Event.SELECT, onFileSelected);
public function onFileSelected(e:Event):void {
var stream:FileStream = new FileStream();
stream.open(e.target as File, FileMode.READ);
loadTxt.text = stream.readUTF();
}
Plus additional question: Where is the best location to save files in the ANdroid mobile?
You can write your file manager, it should not be difficult. Scan a directory with method "getDirectoryListing":
var file:File = File.applicationDirectory.resolvePath('myDirectory/');
var filesList:Array = file.getDirectoryListing();
and show a list of files.
I'm listing files in the "applicationDirectory" and getting the names with the extension,
For example "myVid.mp4".
I would like to get only the filename without the extension(mp4)
Here is my code so far
var subjDir:File = File.applicationDirectory.resolvePath("videos");
var files:Array = subjDir.getDirectoryListing();
var filesName:Array = new Array();
for (var i:uint=0; i<files.length;i++)
{
trace(files[i].name);
trace(files[i].nativePath);
filesName.push({label:files[i].name,fpath:files[i].nativePath});
}
Thank's in advance!
trace (files[i].name.substr(0, files[i].name.lastIndexOf('.')));
This will remove the file extension:
trace(files[i].name.replace(/\.[^\.]*$/,""));
How to create a REALY NEW text file (.txt) using AS3 adobe AIR. Most articles are writing to EXISTING text file (text file already exist).

How to create new File txt by using Adobe Air
Thank you.
//create a reference to the file in the applicationStorage Directory
//(for more directories, look at http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/filesystem/File.html
var fileToCreate:File = File.applicationStorageDirectory;
fileToCreate = fileToCreate.resolvePath("myfile.txt");
//create a filestream to write to the file
//the write and/or creating the file is done with the FileMode in the open() function
//look at the table that describes what FileMode does what here: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/filesystem/FileMode.html
var fileStream:FileStream = new FileStream();
fileStream.open(fileToCreate, FileMode.WRITE);
//write some string to the file
fileStream.writeUTF('this is a string to write to the file');
//finally, close the filestream
fileStream.close();
EDIT: changed filemode from READ to WRITE. READ does not create the file ofcourse :)
I try to launch a programm with NativeProcess on Mac.
pathEV="/Applications/MyFolder/MyAppOSX.app"
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var fileEV:File = new File();
fileEV=fileEV.resolvePath(pathEV);
nativeProcessStartupInfo.executable = fileEV;
var process:NativeProcess = new NativeProcess();
process.start(nativeProcessStartupInfo);
But this error appear:
Error #3214: NativeProcessStartupInfo.executable does not specify a valid executable file
Can you help me to solve that?
Thanks
Haven't tested it yet, but I assume you'd need to run open with the path to your application as a parameter, like this:
pathEV:String="/Applications/MyFolder/MyAppOSX.app"
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var fileEV:File = new File();
fileEV=fileEV.resolvePath( '/usr/bin/open' );
nativeProcessStartupInfo.arguments = Vector.<String>([pathEV]);
nativeProcessStartupInfo.executable = fileEV;
var process:NativeProcess = new NativeProcess();
process.start(nativeProcessStartupInfo);
And yes, this definitely needs extendedDesktop rights
FYI: The Vector shizzle is correct, I use it to convert the array to Vector, not as a constructor function
Here's an explanation how to launch .app files from the terminal
Could it be that you need to add <supportedProfiles>extendedDesktop</supportedProfiles> to your manifest file?
Also, I believe.app is not an executable. Its actually just an application bundle within which exists the actual executable. Try pointing to /bin/ls first to make sure all else is OK and then dig inside the .app folder to find your executable.
Why do you need a nativeProcess? Why not just use fileEV.openWithDefaultApplication() ?
