Is there any how I can test whether a mobile browser supports flash using web technology?
I know most mobile browsers don't support javascript,
how can I chec开发者_高级运维k this?
Don't hold it against me if it isn't helpful ;) But this seems relevant: http://kb2.adobe.com/cps/140/tn_14086.html
From the site (edited and abridged):
This approach to Flash Player detection relies on two key elements; a Flash plug-in "sniffer" that uses the GetURL action which only the Flash 4 Player will respond to, and an HTML page with a META refresh tag.The index page of the site will use a Flash movie to detect for version 4 of the Flash Player and direct those browsers to the Flash 4 content. If the user hits the index page either without the Flash Player or with version 2 or 3 of the player, the META refresh tag will automatically send them to a non-Flash page which will prompt them to download version 4 of the Flash Player. This scheme works without using any JavaScript, making it both simpler and more browser-compatible.
Creating a Flash 4 "sniffer":
Create a new Flash movie ...
In Modify > Movie set the movie's dimensions to 18px wide and 18px high. This is the smallest a Flash movie can be created ...
Insert keyframes on frame 1 and 2. Select frame 2 and choose Modify > Frame. In the Frame Properties dialog box attach a Get URL action. In the URL field put the URL to the HTML page that will make up the real Flash site. Most importantly: put the URL in quotes and set the Get URL field to expression. This assures that only the Flash 4 player will execute this action.
Add another action to this list - Stop. Select OK.
Using the Flash 4 Publish feature, create an HTML file using the Flash 4 only (default) template. This will be the index.html page for this Flash site.
Creating a META refresh tag in a HTML document:
- Open the index.html document in an editor such as Macromedia's Dreamweaver.
- In the
<HEAD>tag of the HTML document create a META refresh tag ...<META HTTP-EQUIV="Refresh" CONTENT="10; URL=alternative.html">... The file name "alternative.html" should be substituted with the name of your page that contains the alternate content, in the case that the user does not have the Flash 4 Player installed.- [Create the alternative page - alternative.html - or whatever you've named it]
- [Add appropriate content and links to the relevant flash download pages]
Use the navigator properties mimeTypes and plugins Adobe provides documentation on how to check this.
if(navigator.mimeTypes && navigator.mimeTypes["application/x-shockwave-flash"]) {
// hasSupport
}
Most browsers (including mobile ones) sent a Accept header as part of the http request which will tell you what content-types it can accept so you might find application/x-shockwave-flash there.
I'm not sure if this is reliable anymore on mobile browsers though as have been out of the mobile industry for a couple of years
Another option is to query sources like WURFL or UA-Prof to try determine if the phone supports what you require - but this will not always work - especially if an alternate browser is being used on the phone
