[ratheeshrohini]

Hi,
Can any one show me a code to check whether a browser supports my sencha touch app? this is urgent.I f the browser doesnot support html5 I want to show an error message

You can either check the useragent or use Ext.is checks

Hi can u show me the code to check user agent in ext js4?

Currently in my app, on a page request I simply search for the word "WebKit" (case-insensitive ofc) in the UA. If its there, then redirect to the Sencha App. If not then normal web page.

Fyi, this works perfectly fine for Apple, Android, and Kindle devices (This code's in a prod environ, so you can take it for granted that it works )..

But, mitchellsimoens (or anyone else from the Sencha team for that matter), could you guys advise us better - if this is correct or is there something better to search for!?!!

Thanks!
Kris

It really just depends what you want to target. If you want all WebKit browsers then that will be ok. If you want only certain devices then you need to get a little smarter.

Oh.. that's cool then . But hope you understand that the main question here is:
What are, and how to detect all the browsers/devices that "will" support Sencha Touch Apps properly!!
... because ultimately our aim would be to display this cool Sencha App in as many compatible devices as possible!! Hence the question "how".
Anyway, if, as you say, a simple "WebKit" string search does the job right, I'm totally cool with it!! If not, I'm all ears...

Btw, we are (finally) migrating our code from Sencha 1.1 to 2.0 now. [Fingers-crossed]
Are going through all the available bookmarks and docs to do so. But if there's anything else extremely helpful, do let us know.
(Hope we make it in time. Wish us luck!
