How to make a sencha touch app offline usable with the html5 cache manifest!
i made my test sencha touch app “remember the card” a memory like browser game offline usable and want to share the steps how to do this in this little “How to”.
If you need general information about the cache manifest take a look on the html5 working draft.
Do the following steps to make your app offline working.
1. create your cache manifest file
create a file yourappname.manifest in your application root. In the file enter all files you have to cache to make your app working offline.
in my case my rememberthecard.manifest file looks like this:
CACHE MANIFEST #rev5 index.html sencha-touch-beta-0.90/resources/css/ext-touch.css css/memory.css sencha-touch-beta-0.90/ext-touch-debug.js js/memory.all.js images/card-01.jpg images/card-02.jpg images/card-03.jpg images/card-04.jpg images/card-05.jpg images/card-06.jpg images/card-07.jpg images/card-08.jpg images/cover-leaf.jpg tablet_startup.png phone_startup.png
see all options you can use in the .manifest file here.
2. Add your manifest to your application .html file header
<!doctype html> <html manifest="yourappname.manifest">
3. Add type manifest to your apache config
Add following entry to your apache config (for example apache.conf or vhost.conf )
AddType text/cache-manifest .manifest
4. Add .htaccess with expire configuration for your *.manifest file to your app root
ExpiresActive On ExpiresDefault "access"
5. Thats it 
Now try if everything work, open you app on your mobile device.
Save the link to you homescreen.
Now turn off all your networkconnections and open your app from your homescreen.
It should now work offline.
Hope this helps

I played with Sencha Touch and wrote a touch based memory like game.
For me as Ext JS developer it was pretty easy to write that application.
This cause Sencha Touch has the same syntax like Ext JS.
My first application a memory like browser game run on iPhone, iPad and Android.
It use the “tap” event and flip the cards after the tap with one of the nice animations.

ExtJS debug events fired by a component
with following code snipped you can easily observe all events fired by component.
Ext.util.Observable.capture(
Ext.getCmp('CmpId'),
function(e){
console.log(e);
}
);
On firebug console you can now see the names of the fired events .
