no file-saving after AIR Update

Question

I updated my air app from air32 to latest harman´s air50.

After the update, files can no longer be saved on Android.

var myFile: File = File.documentsDirectory.resolvePath("/mnt/sdcard/Tfzf Helfer/activation.tfzfhelfer");
    var fs: FileStream = new FileStream();
    fs.open(myFile, FileMode.WRITE);
    fs.writeUTFBytes(dateiname);
    fs.close()

permission in the xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"/>

You can update the code in below :

var myFile: File.documentsDirectory.resolvePath("Documents").resolvePath("Tfzf Helfer/activation.tfzfhelfer");
var fs: FileStream = new FileStream();
fs.open(myFile, FileMode.WRITE);
fs.writeUTFBytes(dateiname);
fs.close()
