However, some capabilities of Adobe AIR are not listed as properties in the Capabilities class. They are properties of other classes:
Property | Description |
---|---|
NativeApplication.supportsDockIcon
| Whether the operating system supports application doc icons. |
NativeApplication.supportsMenu
| Whether the operating system supports a global application menu bar. |
NativeApplication.supportsSystemTrayIcon
| Whether the operating system supports system tray icons. |
NativeWindow.supportsMenu
| Whether the operating system supports window menus. |
NativeWindow.supportsTransparency
| Whether the operating system supports transparent windows. |
Do not use Capabilities.os
or Capabilities.manufacturer
to
determine a capability based on the operating system. Basing a capability on the operating system
is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing.
You can send capabilities information, which is stored in the
Capabilities.serverString
property as a URL-encoded string, using the
GET
or POST
HTTP method. The following example shows a server
string for a computer that has MP3 support and 1600 x 1200 pixel resolution, that is
running Windows XP with an input method editor (IME) installed, and does not have
support for multichannel audio:
A=t&SA=t&SV=t&EV=t&MP3=t&AE=t&VE=t&ACC=f&PR=t&SP=t& SB=f&DEB=t&V=WIN%209%2C0%2C0%2C0&M=Adobe%20Windows& R=1600x1200&DP=72&COL=color&AR=1.0&OS=Windows%20XP& L=en&PT=External&AVD=f&LFD=f&WD=f&IME=t&DD=f& DDP=f&DTS=f&DTE=f&DTH=f&DTM=f

There is also a WD
server string that specifies whether windowless mode is disabled. Windowless mode
can be disabled in Flash Player due to incompatibility with the web browser or to a user setting in the mms.cfg file.
There is no corresponding Capabilities property.
All properties of the Capabilities class are read-only.

language | property |
language:String
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0, Flash Lite 4 |
Specifies the language code of the system on which the content is running. The language is
specified as a lowercase two-letter language code from ISO 639-1. For Chinese, an additional
uppercase two-letter country code from ISO 3166 distinguishes between Simplified and
Traditional Chinese. The languages codes are based on the English names of the language: for example,
hu
specifies Hungarian.
On English systems, this property returns only the language code (en
), not
the country code. On Microsoft Windows systems, this property returns the user interface (UI)
language, which refers to the language used for all menus, dialog boxes, error messages, and help
files. The following table lists the possible values:
Language | Value |
---|---|
Czech | cs |

Note: The value of Capabilities.language
property is limited
to the possible values on this list. Because of this limitation, Adobe AIR applications
should use the first element in the Capabilities.languages

Example ( How to use this example )
The Capabilities.language
property returns the ISO 639-1 language code
(for example, "en" for English). The switch
statement checks for the language code and sets
the content of the myTextField
text field to a greeting specific to the
language. If the language code is not supported by the example, the default error string
is returned.
package { import flash.display.Sprite; import flash.text.TextField; import flash.text.TextFieldAutoSize; import flash.system.Capabilities; public class Capabilities_languageExample extends Sprite { public function Capabilities_languageExample() { var myTextField:TextField = new TextField(); myTextField.x = 10; myTextField.y = 10; myTextField.background = true; myTextField.autoSize = TextFieldAutoSize.LEFT; var greetingEnglish:String = "Hello World"; var greetingGerman:String = "Hallo Welt"; var greetingFrench:String = "Bonjour Monde"; var greetingSpanish:String = "Hola Mundo"; var lang:String = Capabilities.language; switch (lang) { case "en": myTextField.text = greetingEnglish; break; case "de": myTextField.text = greetingGerman; break; case "fr": myTextField.text = greetingFrench; break; case "es": myTextField.text = greetingSpanish; break; default: myTextField.text = "Sorry your system's language is not supported at this time."; } this.addChild(myTextField); } } }
languages | property |
languages:Array
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.1 |
An array of strings that contain information about the user's preferred user interface languages, as set
through the operating system. The strings will contain language tags (and script and region information,
where applicable) defined by RFC4646
(http://www.ietf.org/rfc/rfc4646.txt)
and will use dashes as a delimiter (for example, "en-US"
or "ja-JP"
).
Languages are listed in the array in the order of preference, as determined by the operating system
settings.
Operating systems differ in region information returned in locale strings. One operating system
may return "en-us"
, whereas another may return "en"
.
The first entry in the returned array generally has the same primary language ID
as the Capabilities.language
property. For example, if Capabilities.languages[0]
is set to "en-US"
, then the language
property is set to "en"
.
However, if the Capabilities.language
property is set to "xu"
(specifying
an unknown language), the first element in this array will be different. For this reason,
Capabilities.languages[0]
can be more accurate than Capabilities.language
.
The server string is LS
.

localFileReadDisable | property |
localFileReadDisable:Boolean
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0, Flash Lite 4 |
Specifies whether read access to the user's hard disk has been
administratively prohibited (true
) or allowed
(false
). For content in Adobe AIR, this property
applies only to content in security sandboxes other
than the application security sandbox. (Content in the application
security sandbox can always read from the file system.)
If this property is true
,
Flash Player cannot read files (including the first file that
Flash Player launches with) from the user's hard disk.
If this property is true
, AIR content outside of the
application security sandbox cannot read files from the user's
hard disk. For example, attempts to read a file on the user's
hard disk using load methods will fail if this property
is set to true
.
Reading runtime shared libraries is also blocked
if this property is set to true
, but reading local shared objects
is allowed without regard to the value of this property.
The server string is LFD

version | property |
version:String
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 9, AIR 1.0, Flash Lite 4 |
Specifies the Flash Player or Adobe® AIR®
platform and version information. The format of the version number is:
platform majorVersion,minorVersion,buildNumber,internalBuildNumber.
Possible values for platform are "WIN"
, `
"MAC"
, "LNX"
, and "AND"
. Here are some
examples of version information:
WIN 9,0,0,0 // Flash Player 9 for Windows MAC 7,0,25,0 // Flash Player 7 for Macintosh LNX 9,0,115,0 // Flash Player 9 for Linux AND 10,2,150,0 // Flash Player 10 for Android
Do not use Capabilities.version
to determine a capability based on
the operating system if a more specific capability property exists. Basing a capability on the operating
system is a bad idea, since it can lead to problems if an application does not consider all potential
target operating systems. Instead, use the property corresponding to the capability for which you
are testing. For more information, see the Capabilities class description.
The server string is V
.
Implementation
public static function get version():String

hasMultiChannelAudio | () | method |
public static function hasMultiChannelAudio(type:String):Boolean
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 11, AIR 3 |
Specifies whether the system supports multichannel audio of a specific type. The class flash.media.AudioDecoder enumerates the possible types.
AIR profile support: Multichannel audio is supported
only on AIR for TV devices. On all other devices, this method always returns false
.
See
AIR Profile Support for more information regarding API support across multiple profiles.
Note: When using one of the DTS audio codecs, scenarios exist in which
hasMultiChannelAudio()
returns true
but the DTS audio is not played.
For example, consider a Blu-ray player with an S/PDIF output, connected to an old amplifier.
The old amplifier does not support DTS, but S/PDIF has no protocol to notify the Blu-ray player.
If the Blu-ray player sends the DTS stream to the old amplifier, the user hears nothing.
Therefore, as a best practice when using DTS, provide a user interface so that the user can
indicate if no sound is playing. Then, your application can revert to a different codec.
The following table shows the server string for each multichannel audio type:
Multichannel audio type | Server string |
---|---|
AudioDecoder.DOLBY_DIGITAL | DD |
AudioDecoder.DOLBY_DIGITAL_PLUS | DDP |
AudioDecoder.DTS | DTS |
AudioDecoder.DTS_EXPRESS | DTE |
AudioDecoder.DTS_HD_HIGH_RESOLUTION_AUDIO | DTH |
AudioDecoder.DTS_HD_MASTER_AUDIO | DTM |
Parameters
type:String — A String value representing a multichannel audio type.
The valid values are the constants defined in flash.media.AudioDecoder.
|
Boolean — The Boolean value true if the system
supports the multichannel audio type passed in the type parameter.
Otherwise, the return value is false .
