I have a bunch of 40 images loaded from my DB in my ST2 app when I am online, trying to transform them into dataUrls in order to store them in my local storage. I am following this tuto for that: http://www.sencha.com/learn/taking-sencha-touch-apps-offline/
After around 10 files or 1600Mo of data, the service return with a 404 Not Found on all my service requests. Because you are caching all the images previously encoded, my theory is that you have a limitation in the size of this cache ? But I am not sure, any help here ?
Any alternative solution would be great, I really need to store those images offline.
