I have made an iOS and Andoid app with native and webview taps.
So i placed the sencha touch app on my server and load it inside webview.
In iOS it is very fast and works very well but, inside the Android app, the sencha touch app loads but the scrolling is slow and the navigation does just push the first view and then it does notwork any more.
What version of Android are you using? I'm guessing there's a good chance you're using Honeycomb/v3, in which case, give up! Because it has a horrible HTML5 implementation and it's really out of Sencha's hands to get Touch apps working in that environment.
Thank you matfin for your help.
Android had really bad performance with HTML5 in all cases.
The other problem is, that the naviagtion view does not work.
So I have a naviagtion View with the root view, a xlist, and now i tab an item and pushes a 2nd view on the navigation view.
After this action, all buttons and lists does not work any more.
This bug is as well as the performance problem just on android.
