We imagine a world where every digital interaction whether in the classroom, the office, the living room, the airport, or the car is a powerful, simple, efficient, and engaging experience. Flash Player is widely used to deliver these experiences and has evolved into a sophisticated platform across browsers, operating systems, and devices.
We continued to invest in building a range of technologies and prepared for the day that innovation on the web would ignite again. The days of innovation have now returned in full force, and I am delighted to see rich Internet applications coming into their own with Web 2.0.
The AIR project is actually our third attempt at creating this new environment. The first two attempts were part of an experimental project called Central which was code named Mercury and then Gemini after the United States space program, and with AIR code named Apollo. We learned a lot from those first two projects, and as I like to remind the team, Apollo is the one that actually went to the moon.
With AIR, you can leverage your existing web development skills (Flash, Flex, HTML, JavaScript, Ajax) to build and deploy RIAs to the desktop. Just like web publishing allowed anyone with basic HTML skills to create a web site, AIR will enable anyone with basic web development skills to create a desktop application.
As a developer, you can now create a closer connection to your users. With the browser, you have a fleeting, somewhat tenuous, connection to users. They browse to a page, and then they’re gone. AIR enables you to create an experience that can keep you continuously connected to your customers. Just like a desktop application, AIR applications have an icon on the desktop, in the Windows start menu, or in the OS X dock. Also, when you’re running a web application today, it’s a separate world from your computer. You can’t easily integrate local data with your web application. For example, you can’t just drag and drop your Outlook contacts onto a web-based mapping application to get directions to your friend’s house. Yet with AIR applications you can, as it bridges the chasm between your computer and the Internet.
0 ActionScript is the official programming language of Adobe’s Flash platform. While originally conceived as a simple tool for controlling animation, ActionScript has since evolved into a sophisticated programming language for creating content and applications for the Web, mobile devices, and desktop computers. True to its roots, ActionScript can be used in many different ways by many different kinds of programmers and content producers. For example, an animator might use just a few lines of ActionScript to pause the playback of a web animation. Or, an interface designer might use a few hundred lines of ActionScript to add interactivity to a mobile phone interface. Or, an application developer might use thousands of lines of ActionScript to create an entire email-reading application for web browser and desktop deployment.
ActionScript 3.0 is an object-oriented language for creating applications and scripted multimedia content for playback in Flash client runtimes (such as Flash Player and Adobe AIR). With a syntaxreminiscent of Java and C#, ActionScript’s core language should be familiar to experienced programmers.
To make data from a web server available to SWF files from other domains,you can create a cross-domain policy file on your server. A cross-domain policy file is an XML file that provides a way for the server to indicate that its data and documents are available to SWF files served from certain domains or from all domains. Any SWF file that is served from a domain specified by the server ’s policy file is permitted to access data or assets from that server. Cross-domain policy files affect access to a number of assets,including the following:
Data in bitmaps,sounds,and videos
Loading XML and text files
Access to socket and XML socket connections
Importing SWF files from other security domains into the security domain of the loading
SWF file
Policy file syntax
The following example shows a policy file that permits access to SWF files that originate from *.marciorosa.com ,www.friendOfMarciorosa.com and 192.0.34.166 :
<?xml version="1.0"?> <cross-domain-policy> <allow-access-from domain="*.marciorosa.com"/> <allow-access-from domain="www.friendOfMarcioRosa.com"/> <allow-access-from domain="192.0.34.166"/> </cross-domain-policy>
When a SWF file attempts to access data from another domain,Flash Player automatically ttempts to load a policy file from that domain.If the domain of the SWF file that is attempting to access the ata is included in the policy file,the data is automatically accessible.
By default,policy files must be named crossdomain.xml and must reside in the root directory of the server.However,a SWF file can check for a different name or in a different directory location by calling the Security.loadPolicyFile()method.A cross-domain policy file applies only to the directory from which it is loaded and to its child directories.Soa policy file in the root directory applies to the whole server,but a policy file loaded from an arbitrary subdirectory applies only to that directory and its subdirectories.
A policy file affects access only to the particular server on which it resides.For example,a policy file located at https://www.adobe.com:8080/crossdomain.xml will apply only to data-loading calls made to www.adobe.com over HTTPS at port 8080.
A cross-domain policy file contains a single
If you specify an IP address,access is granted only to SWF files loaded from that IP address using IP syntax (for example,http://65.57.83.12/flashmovie.swf ),not those loaded using domain-name syntax.Flash Player does not perform DNS resolution.
You can permit access to documents originating from any domain,as shown in the following example:
<?xml version="1.0"?> <!--http://www.marciorosa.com/crossdomain.xml --> <cross-domain-policy> <allow-access-from domain="*"/> </cross-domain-policy>
Each
If data to be loaded is on a HTTPS server,but the SWF file loading it is on an HTTP server, Adobe recommends that you move the loading SWF file to an HTTPS server so that you can keep all copies of your secure data under the protection of HTTPS.However,if you decide that you must keep the loading SWF file on an HTTP server,add the secure=”false” attribute to the allow-access-from>tag,as shown in the following code:
<allow-access-from domain="www.marciorosa.com"secure="false"/>A policy file that contains no
O Open Screen Project levará as rich Internet experiences across televisions, personal computers, mobile devices, e consumer electronics, o Open Screen Project suportará technologias líderes, incluindo Adobe, ARM, Chunghwa Telecom, Cisco, Intel, LG Electronics Inc., Marvell, Motorola, Nokia, NTT DoCoMo, Qualcomm, Samsung Electronics Co., Sony Ericsson, Toshiba and Verizon Wireless, e provedores de conteúdo como BBC, MTV Networks, e NBC Universal, levando toda rich Web e video experiences, a toda variedade de dispositivos.
O Open Screen Project remove qualquer barreira de uso do Adobe® Flash® Player e no futuro, Adobe AIR™, fazendo com que qualquer empresa posssa inserir ambos em seus produtos sem custos de direitos de software. Isso é um grande passo para a área de desenvolvimento, e uma boa resposta a abertura do SDK para iPhone para desenvolvimento de aplicações.
Veja algumas barreiras que cairam com este projeto:
Remoção das restrições na utilização das especificações SWF e FLV/F4V e
publicação das APIs de portabilidade do Flash Player para dispositivos
Publicação dos protocolos Adobe Flash Cast e AMF
Não só foram publicadas as especificações SWF e FLV/F4V, como as especificações dos formatos de comunicação de dados usados pelo Flash Player.
Remoção dos custos de licenciamento do Flash Player e Adobe Air
Passa a tornar-se gratuíto distribuir o Flash Player e o Adobe Air.
