How to make a sencha touch app offline usable with the html5 cache manifest!

Nils Dehl — Sun, 20 Jun 2010 12:46:59 +0000

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

phone_startup.png

see all options you can use in the .manifest file here.

2. Add your manifest to your application .html file header

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.

iPhone 3GS + Mails per IMAP-IDLE

Nils Dehl — Sun, 28 Jun 2009 20:59:13 +0000

Auf meinem iPhone 3GS greife ich auf IMAP Mailkonten auf meinem Server zu. Dank IMAP-IDLE sind dabei neue Mails auch direkt immer auf meinem iPhone verfügbar. Anders als bei Push-Diensten wie Microsofts Direct Exchange, wird bei IMAP-IDLE [1] die Verbindung zum Server durch das Handy offen gehalten. Es sendet hierfür in regelmäßigen Abständen (bspw. alle 15min) “IDLE” Commands an den Mailserver.
