Which UI to use for Cordova Android/iPhone app development [closed]
Why not try Ionic Framework
I have used ionic, angularJS, phonegap/cordova together for Android/iPhone development and its quite nice. Not that hard to learn and quite fun to work with.
Choosing Mobile frameworks is based on the requirement of the app. There are various frameworks available, most popular and widely used are jQuery Mobile, Sencha Touch and others..
This article has introduction to Cordova/Phonegap and comparison to some of the Mobile Frameworks, you can choose it based on the requirement. For best practices in Cordova, it is always better to use SPAs - SinglePageApplications for that jQuery Mobile and Angular/Backbone can be combined.
For your other question on older phones like Android 2.3 phone: These frameworks are built for/using many features like HTML 5, CSS 3, localStorage, local database as well and others.. so HTML 5 support is not completely supported in older phones/Android versions, also local storage, sqlite and many others..
You can check the support for HTML 5 here, also for others you can check in the same website or Mozilla Developer Network for JavaScript.
First and foremost - your Cordova applications should adopt the SPA (Single Page Application) design. Loosely defined, a SPA is a client-side application that is run from one request of a web page. The user loads an initial set of resources (HTML, CSS, and JavaScript) and further updates (showing a new view, loading data) is done via AJAX. SPAs are commonly used for more complex client-side applications. GMail is a great example of this. After you load GMail, mail views, editing, and organization are all done by updating the DOM instead of actually leaving the current page to load a completely new one. More.....
Examples of SPA libraries(UI) you can use in your Cordova applications are:
1) AngularJS
3) Kendo UI
4) Sencha Touch
5) Backbone
