We are building GWT Web Application mainly focused on iOS + Safari platform. I need to debug and profile the application directly on the device. We are working only on Windows computers.
As mentioned e.g. here, one cannot use iOS Web Inspector built in in Safari, since the newest version of Safari is not available for Windows.
So we started to use alternative tool Telerik AppBuilder to do it, as suggested e.g. here. I am quite happy with it and it is getting more and more powerful.
However I would like to see comparison of those two tools by someone, who has experience with both of them. I am considering, whenever to invest into Mac computer to be able to use Web Inspector. Are there any features or advantages in Web Inspector, which Telerik does not have?
Based on my further experience, Telerik is good enough to do all debugging we need. And since it is based on same API as debugger in Safari, it has about same features. It is not as good as Safari debugger, but close enough. Investment into Mac computer just for debugging features is not worth the advantages.
I am new to mobile programming, and I want to build a mobile app to fill few forms, offline, and then sync them later, when internet access is available, with a database on an online server through a VPN connection.
At first, I thought about learning Windows8 Phone App development, but then I heard/read about Phonegap and Jquery Mobile! and I am a bit confused which one would be better to use, considering two things:
1- Which one you think would be good for my app's functionality
2- Which tool would be more beneficial on the long run (in the mobile programming world).
Any advice would be very much appreciated.
With these functionality I don't thing you don't need many mobile dependent features rather you need more web features. For your first question, answer could be that technology in which you are more comfortable. But it also depends how you want to sync your data. In background or when the app is open. If you want to sync data in background that means app is closed, you have some data to send in server, and internet access is there, then you'll need some native windows phone code. In that case if you use phonegap ultimately you will need some native code to deal with it, may be you'll need to write a plugin to communicate between phonegap and native code. And if you don't need background process, if you want to send data to server only when your app is opened,phonegap can work like a charm. It'll be easy to communicate between 2 web technology.
For your second question, ofcourse phonegap is great technology to learn to deal with cross platform. If you need to make apps not only for WP rather for all platforms then phonegap is great. Having said that it's necessary to mention phonegap has it's quirks too. Native code always has it's benefit. Phonegap can't completely overcome native code. But if you are willing to compromise a bit, then it's easy to learn phonegap,a familiar tech than all those platform dependent techs like objective-c, android etc.
(N.B. I'm not an expert, it's just my experience so far)
I have made my first app in the Android platform. However this is not the only platform and I want to get my apps published on at least Android and iOS platforms.
I would like to have one developing platform for both platforms. What is the options?
I have now tried Flex, Air with Flash Builder. It seems quite promising but the future seems to be a bit uncertain and are also more expansive.
It would be interesting to have some suggestions about what developing tools to focus on if I would like to develop apps on both Android and iOS.
It depends what kind of apps you want to build (i.e. Games, Content Aggregators, etc.) because each 3rd party "App-Generator" that deploys to multiple platforms has their strengths and weaknesses.
Here's a (brief) list:
Appcelerator's Titanium SDK - leverages mobile-browser-based features, mostly for content-aggregators, simple or core feature list on platforms
Corona - leverages LUA-scripting language for 2d / more simple games and applications; has a growing user-base and community; possible to leverage for core-experience as well
Unity - 3d experience, games, usually for more high-end, premium experiences
If you're going to develop on the platform, I always recommend build to that platform's language since you'll never have to worry about what happens when the language is upgraded and your "app-generator" hasn't upgraded yet.
It will also help you to learn the language on that platform (Java, C#, Objective-C, etc.)
I know it's old topic but for those who are still looking for rapid mobile development there is also Kinetise that is code-less tool and offers also backend system/CMS.
You can use Sybase Unwired Platform. It has Device App Designer which can create applications for Blackberry ,Android and iOS.
If you are aiming for high quality, I don't think there is any other way than going native for each platform. Also keep in mind that different platforms have different UI guidelines and principles, and doing a multiplatform project is not a good enough reason to abandon those guidelines.
I recommend phonegap: http://www.phonegap.com
This is kind of a dumb question but I've aware of classic style JDE development for Blackberry but I've never tried using WebWorks. BB website says that it's possible to build applications for both smartphones (OS 6.0+) and tablets - sounds fantastic, but what's the price?
Is here anyone using WebWorks on a daily basis and capable of describing pros and cons?
Thanks in advance
I would suggest using it if you build webOS applications before hand. It make porting to the blackberry a breeze.
Use WebWorks if you know html5, Css3 and javascript over Java and C++.
I haven't ran into any issues with the webWorks, ported two applications without running into any issues. Its your standard html5, css3 and javascript you love with blackberry APIs
WebWorks is a good development choice, particularly as it allows easy migration from earlier BB OSes to BB10. It's mostly standard web technologies (HTML5, CSS3, etc.) and the team seems focused on making it perform well (e.g. hardware accelerated WebGL graphics) while at the same time providing BlackBerry-specific APIs to make WebWork apps capable and with good UX (e.g. you can make it look like a native app).
For native apps, you should look into Cascades. This is a modern development environment with good tooling, accelerated graphics, and APIs for building snazzy apps. It's the one that will most be a "BlackBerry app".
AIR remains an option, but I would recommend WebWorks over AIR, as even Adobe is migrating from Flash to web technologies. Likewise, you can develop Android apps on BB10, but unless you are keen on Java programming, you will get more cross-platform support from WebWorks (or even AIR) so there's no particular reason to go the Android route.
WebWorks API is limited, for example it does not have socket, so you cannot port a VNC (UltaVNC, tightVNC ..) to it but you can do it with JDE.
For UI, WebWorks allowed me to write UI of acceptable quality quickly and easily, a thing that I have never succeeded with JDE.
Still on the UI side, I can make use of multi-touch (PlayBook), I don't think this one is possible with JDE.
So depending on your needs you should go either WebWorks or Native, having heard that Java may not be supported in BB10, and Air may not be future proof (Adobe favors HTML5 instead of Flash). Android appli has some lag on start up when it is run on PlayBook, some customers are sensitive to the initial even just one time slow response time.
I'm a huge proponent of Webworks. Ever since I've started using it, it quickly became the default option for my apps going forward. Especially for someone like me who is just writing a few apps on the side, I don't have the time to do it in c++.
The apps I'm writing revolve around home automation. They are client/server based from the get go.
Here's why I like it:
First and foremost, native API support. I can very easily create my own active frames, import invocation from other apps (think camera, stuff like that). I can export portions of my webworks app as an invocation card! Which means I can write say 3 unique apps (in this case home automation, lights, thermostat, security cameras). And I can very easily pull features from each app into the other. Maybe I want to turn my lights on in the living room, I can also import the camera card from my IPcam app and view the results, without having to add that code into my lights app and maintain two separate code lines.
Rapid design. Since I've been dabbling in html since I was a kid, it's now very easy for me to whip up an appealing UI in little time. Because web engines these days offer good performance in terms of graphics capability, I also can make apps that behave very fluid.
Considering the time to make something beautiful, it's hard for me to leave webworks and go for something in c++. Also the big plus is often these apps I'm making are intended for multiple devices, namely an app on my phone and being hosted on my personal website. By maintaining two slightly different css files, most of the time I need no code changes, just load a different css depending on if it's a phone or a pc. (Exactly what you'd do if you were developing a regular old website).
For that matter, I actually don't put my code on the device, I host all of my html and javascript, images etc on my server. The webworks app is just the config.xml pointing it's source to my server, and an icon. A glorified website bookmark on the homescreen, only difference is I can use native API and there's no browser bar in the app.
Also, this way I can still continue to edit the same single codeline on my server, and instantly apply changes to the in-browser app and the on-device app.
This is especially cool if you're designing an app where all of it's data is out in the "cloud", say you work for a publication and you want to write a magazine app which pulls content from your servers on the net.

Improve this question
I wonder if I were to develop a mobile Web app (now, in two weeks, or in a month), which one should I go for? Which one would you mobile Web developers go for?
If jQM 1.0 were officially released today, I would most likely embrace it (as long as it actually delivers what it promises). Now that it is in alpha, I wonder whether it is worth to jump into it yet for a commercial grade project? Would Sencha Touch be a better alternative?
Sencha Touch is an application framework (you create your interface programmatically through Javascript) while jQuery Mobile is more of a mobile enhancement library (you write regular HTML for your content, then add jQuery mobile for transitions/animations). jQuery Mobile has an easier learning curve, but Sencha Touch can better simulate "native" apps.
The first question you need to ask yourself is what is the purpose of the application. If you want to release an application for sales on one of the retail outlets (iTunes, Andoid App store), or you need access to device specific functions that are not accessible via local APIs yet (accelerometer, camera, contacts, etc) then you should be thinking Native or one of the hybrid solutions (Appcelerator, PhoneGap, etc.).
If your audience is going to be more in the "mobile web" space, such as a mobile version of a corporate web desktop site, or intranet web application port, then you should be looking at Sencha Touch and jQuery Mobile. The decision between those two is really going to be based on you development experience and and what you feel more comfortable with. Sencha Touch is a VERY robust platform that has a Desktop (ExtJS) and mobile (Sencha Touch) that mirror each other so knowing one pretty much allows you to get up and running with the other. Also, Sencha has moved to an MVC model on the client which really helps to organize client side code and make it much more congruent with server-side development platforms.
The post above is actually incorrect, using the MVC pattern on the client combined with the historyUrl on your dispatch commands gives you the ability to use the browser back and forward buttons of the browser, so that is not exclusive to jQuery Mobile. Also, the Sencha Team's suite of products includes a Designer application that provides Designer which is a WYSIWYG editor that allows for the drag and drog creation of UIs. This company's roadmap has them in the process of updating the Designer app to allow for the drag and drop design of Touch mobile screens and application that will function with the MVC pattern. They are also getting ready to release a new version of the Sencha Command tool that will automatically generate entire MVC application structures for you in a matter of minutes, which you can then add the necessary custom code to round out your application. Lastly, the new SASS theming capabilities allow designers to use CSS3 and SASS config files along with variables and Mixins to generate cross-browser CSS style sheets for your application.
So, the decision of which way to go for the mobile web development question comes down to how comfortable you are with object oriented javascript. If you are very comfortable with it, then Sencha Touch is the way to go as it very extensible class system built into the core engine that can be customized to your hearts content...but if you have minimal experience with JS and you want the server to deliver your UI and don't mind seeing the Address bar drop down to move between pages (less web 2.0 looking), then jQueryMobile is the way to go.
It's pretty obvious that I am biased to Sencha Touch due to its well thought out class structure, extensibility, very active user community, web/mobile continuity, and constant improvement to the core framework and new tools that simplify development efforts. And not to mention that the Touch platform is more mature as jQM has not reached production mode yet.
I've been using jQuery mobile for a while now. It works well under Blackberry 6, iPhone, and Android.
I wrote an article about it here: jQuery mobile alpha
Though it's alpha, they are showing good progress. I've been looking into their development in github, seems like there's going to be cool stuff by early 2011.
UPDATE 2011-12-01 jQuery Mobile relased version 1.0, finally out of alpha. Read more about it here: http://jquerymobile.com/blog/2011/11/16/announcing-jquery-mobile-1-0/
If you're going to make a mobile version of a website, I am going to use jQuery Mobile. If you're going to make a “native” mobile application, I will be more likely use Sencha Touch.
http://tysonlloydcadenhead.com/blog/jquery-mobile-vs-sencha-touch
Sencha touch has lived longer than jquerymobile but I found that jquerymobile handles device back button much better than SenchaTouch.
I always consider back/history button handling is important in my apps, so I prefer jquerymobile.
I always consider myself a JavaScript programmer, but I like the fact that I rarely need to to type any JavaScript code when I use jquerymobile.
jquerymobile design is brilliant IMHO.
I am also in favor of sencha, JQM is really slow and failed to give an impression of an native app.
Praveen
why limit yourself...
Look into PhoneGap and Titanium Appcelerator
the make the comparison based on what you are trying to accomplish. I know Sencha Touch has a licensing fee and like you said jQM is not officially released yet.
This is a great time to be in the mobile space because there are so many viable options
I think jQuery mobile is easier to learn and seems to be very promising. Version 1.0 is not yet available, but its going to be a good product. I find it very attractive because it is based on jQuery - simplicity is the motto
Don't forget that there is also Dojo Toolkit Mobile. It looks nice, at least at first look and it is built on top of the proven and solid Dojo Toolkit core. http://dojotoolkit.org/features/mobile.
The Dojo Toolkit don't get too much audience recently but it looks like they made a lot of progress from the times it was a bit heavy, I think it is worth looking at it.
I've been trying out the sencha architect and to be honest ithas been a nightmare to get running.
My background is DotNet, html, javascript, VB, java and have been using eclipse etc for a while so am not a huge newbie with figuring out dependencys etc.
Here is what I have struck:
I went to the Sench site, downloaded Architect.
It then got me to download toolkit and sencha touch. I downlaoded exactly what was recommend / instructed by the help files / site.
I have Sencha Architect V2.1.0 Build 584., sencha-touch-2.0.1.1-commercial.zip, SenchaSDKTools-2.0.0-beta3-windows.exe
I also downloaded and installed a new java sdk / run time etc. The install has been done on a dead clean XP box (vmware). Web server is xampp.
Sencha does not recognise the SenchaSDKTools-2.0.0-beta3. You have to hack it using hard to find instructions. Even after hacking it the architect fails to use the proper SDK and gives error messages on deployment.
There have also been numerous errors to figure out along the way and issues where data just wont load even having followed instructions to the letter.
I have spent 11 hours getting to the point where the application will run properly without whinging but it wont deploy. It is bad enough learning a new tool / framework etc without the ide causing grief and the "instructional demos" leading you up the path.
There are lots of people getting the same errors all over.
After 15 hours of effort I am giving it up as a bad job and am returning to IBM XPages / PHP and Blueprint CSS with old fashioned, hand coded html5 / CSS3 and jquery / Ajax / JSon apps.
My reason for doing this: Application Architect keeps pushing you back to the command line. I love the command line, give me a bash shell and vi and I'm good to go. However for complex, multi file deplyoments such as mobile apps a good IDE is worth its weight in gold. Architect is not there yet. I keep needing to lift the hood and hack to get things working.
I originally looked at Sencha for a 12 year old who is interested in mobile apps and is looking for an ide to use. I tried it out - it is not suitable - even getting a hello world type app running is going to be too much for a newbie and the first app in the help files doesnt explain itself but has you copying code for pulling data from a web site you have to sign up for. (ccitybars app).
A big improvement for sencha will be when Architect works out of the box (possibly an installer with sdk, tools , touch and architect all in one) and the fisrt app -walk through is a simple hello world that then builds to entering data, saving data and then displaying data before going multi form.
I was faced with the same choice about half a year ago, then went for jQTouch instead of Sencha Touch, which I found to be extremely Javascript centered. I'm currently working on a port of that same project to jQuery Mobile and I think the transition will be much smoother than it would have been with a Sencha Touch project.
If you know basic PHP I strongly suggest jqmphp.com. Up and running in less than 3 days a whole online mobile based site to order food!
MoSync team has recently done an interesting comparison:
Which Mobile JavaScript framework is the best: jQuery Mobile, Sencha Touch, jQtouch, or Kendo UI?
http://www.codefessions.com/2012/04/mobile-javascript-frameworks-evaluation.html
http://www.codefessions.com/2012/04/which-mobile-javascript-framework-is.html
http://www.codefessions.com/2012/05/which-mobile-javascript-framework-is.html
jQueryMobile wins but huge boost in arm is because of licensing. I prefer jQueryMobile because I don't want someone(thing) else to write my markup, that way hacking becoming difficult (at least for me), however, I do have couple of HTML5 apps under my belt now, one each in jQM and Sencha Touch. Sencha Touch makes it smoother, very hard to learn though while jQM gets you started in a day, there are bug but you usually get around them because of amazing web community around this framework.
I've built a nice production app in a few days using Sencha Touch 2.0 and it's delivering as documented. And, it's FAST. There might be some bugs, but, when I've run into one (which, is rarely), there seemed to be many ways to approach a solution so that it's really not that relevant.
Sencha Touch looks great but it is difficult to use. The Sencha support forums offer minimal support. Sencha Touch 2.x is still in alpha is quite buggy
Sencha touch will be the best option is you are just starting because it is well documented and it has a community support. Also, with phonegap, you spend more time on the development and less on things about other mobile platforms. Phonegap will build the application for you , once you upload it to the builder .
Comparing the two is like comparing apples and grapes...though you want to develop mobile apps with both, the level of comfort with either depends entirely on you.
This chart might be helpful if you want to compare the features : http://www.markus-falk.com/mobile-frameworks-comparison-chart/
Sencha Touch based apps can only work on WebKit based browsers. JQueryMobile based apps can work on all mobile web browsers.
I think you can go ahead with JQueryMobile for next 2 to 3 years. I am expecting in 2-3 years all mobile browsers will be based on WebKit engine. Once all mobile browsers start supporting WebKit, move to the Sench Touch mainly because of very good quality user interface.
I suggest KendoUI
It is unbeatable and fast performance in a training of couple of days. Not to mention the fast update and new features and support for server side wrappers (asp.net, php, jsp). It is unique!
I have used both and they each have conditions where one is better suited then the other.
In my opinion you would use JQueryMobile when
1. You need a quick and light weight mobile implementation of an web application.
2. You have time constraints (definitely faster to learn and implement then Sencha Touch).
3. Native look and feel is not a requirement.
When making an extension to an existing web application where relatively simple functionalities have to be extended to extended to mobile (really fast and easy) I found JQM to be extremely useful and straight forward.
In my opinion you would use sencha when
1. You want a native look and feel
2. You want a higher degree of functionality on the mobile side (possible access to native api's through phone gap)
3. Targeting the latest smartphones (performance is impressive)
