We are currently evaluating Ext JS 4 for building the UIs of our enterprise application.
We want to ensure that the application is seamlessly accessible over desktop web browsers as well as mobile devices(at least the Android-based phones,iPhone).
I referred to some threads in various Sencha forums e.g :
(This thread talks about 'soft link to extjs lib' (???) )
We need to know whether :
1. UI created using plain Ext JS 4.x renders directly & properly on various mobile devices
2. If yes,the ways in which the rendering can be made efficient in terms of data transfer(ex. js files) and response time
3. If no, what approach needs to be taken to run the same application over mobile devices
Any guidance is highly appreciated.
