Sencha vs SprouteCore - mobile

I need to develop web based mobile apps, and considering mobile frameworks.
What's easier to learn? what support more devices? please give me directions

Trends
JQuery mobile strives for the widest range of support ( which for me is the clincher )
As to whats easier?
That depends on what you know ( for example, I was able to pickup sencha touch quite easily because I already did quite a bit with extjs and the syntax is very similar, I would imagine this is true for Jquery mobile and jquery aswell )

OnsenUI vs Ionic Framework

I want to start developing a mobile hybrid app using angularjs, css3 and html5. Was searching for a framework and found these two. Both are looking very nice however I was not able to get a good comparison between both of them. Can anyone please list down pros and cons for both.
A comparison between them in terms of scalable, out of the box components, speed and compatibility with Angular and devices targeted will be very helpful
One year has passed since both frameworks were released. Onsen UI is currently in stable 1.2 version while Ionic is in the last release candidate state.
I have worked with both of them so let me give you a short overview, I also wrote a much larger blog article, you'll find it at the end of this answer.
I won't go into much details about the core framework; if you have a previous AngularJS knowledge you will easily transition to Ionic or Onsen UI.
Both frameworks are built around AngularJS and they heavily depend on directives, you can also easily build your custom directives. Onsen UI also features a jQuery support (unnecessary if you ask me).
Both frameworks support Android 4+, iOS 6+ (some features are available on Android 2.3), Onsen UI also officially supports Firefox OS and desktop browsers. Ionic don't have an official desktop support, but it will still work (it will not be pretty, imagine ).
Ionic currently don't support Windows Mobile platform (it will have it in the future); Onsen UI support is currently in development (since November 2014).
Both frameworks support some kind of splitview feature so they can be used for table development.
Both frameworks have a distinctive beautiful looking flat UI. I prefer Ionic over Onsen UI look and feel, but this is a matter of personal taste. Both default themes look iOS 7 like.
Onsen UI supports native looking themes for Android and iOS. Ionic framework uses the same theme for all platforms, but some features will depend on the platform (for example tab look and feel)
Both frameworks have a working theme builder.
Ionic supports SASS while Onsen UI is built around Topcoat CSS library.
Both frameworks have a large widget support (directives)
Onsen UI has a better documentation. It is separated at two different locations. First one is “Components” where you can see different directives and each one has a working example you can use and replicate. Second part is a “Guide” where you are guided through the application creation process.
Ionic has a disorganized documentation (heavily fragmented). It lacks a real “getting started” tutorial, even if you have previous AngularJS experience. It shows you pieces, but not how to connect them correctly.
On the other hand Ionic has much larger community so you will easily find problem solutions.
Ionic framework has a great official forum + large StackOverflow community. At the same time, Onsen UI uses only StackOverflow as a help center (I would call this a fail).
Onsen UI has an HTML5 IDE called MONACA IDE (great tool), Ionic IDE is currently in production; you can participate in beta test.
Ionic has a growing 3rd party plugin community (for example date picker); I couldn't find any 3rd party Onsen UI plugin
I wrote a much larger article covering Ionic / Onsen UI changes, find it here.
Since both frameworks are pretty new and not very popular (yet!), I don't think anybody has taken the time to do an extensive comparison between the two. I don't even think the final set of out of the box components is determined by the developers themselves yet, active development is still going on.
As for compatibility, hybrid apps run in the native browsers of the devices where they are installed on. Both frameworks need CSS3, so old phones will never be supported by either of the frameworks.
The OnsenUI-tag here on StackOverflow is the only support OnsenUI offers (currently), and at the moment of writing there are 0 questions/answers. Ionic has a very active forum on their website + some questions/answers here on SO.
I think having an active community backing up a framework will eventually lead to a better framework. Therefore I'd go for Ionic. Personally, I find Ionic's standard-design more appealing as well, but you should judge that for yourself.
Ionic
more lean to Angular style like routes,controllers and template and it's structure is kind of complicated in first hand.
command like "ionic start myApp tabs" still don't available in onsenUI
Material Design like "Cardboard" are available
OnsenUI
simpler structure, easy to start
couple with Monaca IDE, some of features are only available only if you use Monaca. otherwise you have to create things by yourself.
supported ios8 design recently
Ionic has a more mature feature and CSS component set and out of the box. Injectable delegate services, representing the UI elements (directives) gives you more control over UI/UX interactions. The development community is (currently) very active and it's gaining traction.
I cannot properly speak to speed/performance between the two but know both are optimized for mobile.
As I develop more, I will report back with comparisons. Good luck.
Just started using ionic after some time native development. Must seriously say it has some great cli features! For example you can start your project from a gist in my opinion this is nice to have for poc's
Havent been able to test everything but what i've seen really impresses me!
It's well documented in there own way, active community and it keeps getting better.
Just wanted to share my thoughts for what it's worth
Im working in Ionic Framework during 1 year with a real project, i have created a game with Ionic, its very special because hybrid app is not best choice if you want create game. When you develop a game you need performance !
However if you develop simple game with few animation, its good.
Here is my game in playstore, its a memory game "Memory Party" :
https://play.google.com/store/apps/details?id=fr.jhaccoun
Why Ionic is a good choice :
very very very good documentation (tutorial, forum, article,...)
stable (ionic 1), you can find many apps in store
Easy to develop (ionic come with many tools to help the developer, you can develop and test in live in your phone without deploy thanks live reload
Many cordova modules are available
you don't need mobile skills, just angularjs, html, css...
Ionic provide beautiful components and you can custom the components if you like
I found Ionic the best for some reasons, like their community support and the documentation. I am still evaluating the onsen from a long time but still havent found the one unique thing that will drift me towards it compared to Ionic

Mobile frameworks for desktop

Came across a great list of current mobile frameworks. With such a huge variety I find it difficult in making a decision as to which to use for a web application to be used on both desktop and mobile.
http://en.wikipedia.org/wiki/Multiple_phone_web_based_application_framework
Has anyone used any of these?
Can any be extended and-or repurposed for use on the desktop?
I would say phonegap is your best bet. As you can use javascript, CSS and HTML to build it, you can definitely reuse that for desktop.

Web application on a mobile platform

First, my question might sound like a duplicate, but I have been going through a lot of questions on this forum and haven't found the answer to what I am looking for.
I have an existing web application built using Java, struts2 and jsps. I want the web site to be mobile - friendly. I am not looking at developing native apps right now. I want the mobile-site to have a native-app like appearance. So if a user goes to the browser on a mobile and accesses my site it should have that native look and feel. So I looked at Sencha touch 2 to begin with. I am new to Mobile development and would appreciate help in understanding how to go about evaluating Sencha touch 2 as a viable option. I see from examples that in ST the UI is mostly built using ExtJs javascript.
My questions are the following
Is there a way to port my existing jsps and html to the mobile view , without building them from scratch?
Since the css for the site is currently built for 'screen' media, this will obviously have to be worked out , but does Sencha Touch
provide any functionality of using an existing css and customising it
for a mobile device?
Appreciate your help,
Unfortunately, the answer to your first question is no.
Java/JSP and Javascript are totally different in essence. No convention could be made to convert between these two.
For the second one, SASS/SCSS might be the things you're looking for: http://sass-lang.com/. It's because Sencha Touch components' CSS properties are build through SCSS files. You can take advantage of these. For further ideas, see: http://www.sencha.com/blog/an-introduction-to-theming-sencha-touch

Rhodes v/s Titanium

Which is the best framework to develop cross platform application. Especially for android and iphone. I have been through the reviews present over the internet, but those seem to be pretty old. I believe both Titanium and Rhodes have developed much over the past couple of years.
One of the basic differences is the nativeness of the two frameworks. Both Rhodes Framework and Titanium claim to be native. Rhodes however is not really native i.e. it uses an embedded Web Browser to display the HTML-coded website. Titanium, however, takes your JavaScript code, and create real native widgets on the respective platforms.
So what's so important about native? Well, it makes the user experience a whole lot better.
Rhodes Framework is best described as a competitor to PhoneGap.
From my knowledge, Rhodes is best for enterprisey apps. I would generally recommended Titanium for most app developers.
Though I have not used Rhodes, I feel Titanium is better based on what I read about Rhodes. The JS syntax in Titaniums is also easy to ramp up on. But, from what I have seen, understanding the working of the native code is useful to understand and explain some of the behavior. There is one more comparison of the frameworks that I found recently here.

Mobile UI frameworks & other UI scripts

I'm looking for the best cross browser compatible swipe script for android, iphone and other touch phones. Has anyone used any of the available frameworks or have you used custom scripts? What is your experience with these?
SenchaTouch
jQTouch
Phone Gap
Unify Project
Any others? I am joining a mobile task force and would like to get more involved in one or more of these communities so I can provide some UI support.
Thanks,
Seth
First of all, let's sort out the apples and oranges.
PhoneGap and Appcelerator Titanium are NOT UI frameworks. They are both Web to Native bridging technologies. They provide JavaScript API's for mobile capabilities like accelerometer, contacts, GPS, telephony, etc. Also, they facilitate the creation of a deployable mobile app (versus a web page)
Sencha Touch, jqTouch, and jQuery Mobile are mobile UI frameworks that provide support for mobile UI concepts, like touch, swipe, transitions, small screen sizes, etc. They can run in a pure web page or be used in conjunction with PhoneGap or Appcelerator Titanium in a mobile app.
I'm not too familiar with the Unify Project, but it seems to be a bundle of PhoneGap plus their own UI framework.
Both Sencha Touch and jQuery Mobile are in early days, but already have some great capabilities and they're moving fast.
SenchaTouch is good, but be aware that it provides no native hardware support, so if you need access to the phone hardware, you will need PhoneGap or equivalent.
I hear good things about jqTouch, but haven't tried is personally.
Another option is Appcelerator. If you need to write an app for mobile devices, it is a really approachable framework. You write javascript code, and their machinery compiles it to the appropriate platform. Note that this is for writing apps that run on a mobile device directly, not for writing apps that run in a browser on a mobile device.
I found jqTouch to be great on top of the PhoneGap technology however you need to understand that all the "good looking" UI kits are built on HTML 5 and so far you'll be disappointed with the HTML 5 support from Android devices. You'd think Google would be on this like ants on syrup but you'd be wrong. The jqTouch works like a dream on almost all iOS based devices and quite poorly on most Android devices.
As for Titanium, it still appears and feels web based and there are no UI styles to my knowledge. This means it "attempts" to look native whereas with PhoneGap and JQT you can get a really nice theme. So if you want "snazy" then go PG and something else. Titanium is far more stable than JQT when you're building for iOS and Android so that is a plus but it would be really nice if they did some kind of theme engine.
note over time this answer will become irrelevant as Android improve their HTML 5 support and those UI frameworks become more stable :)
