I want to deploy my GWT app into Google Play (and maybe App Store in the future). I don't need to use native functions in my app. Just user, password, and I will show one report.
I found mgwt project(http://code.google.com/p/mgwt/). Is mgwt + gwt phonegap the best approach?
Google blog: http://googlewebtoolkit.blogspot.com.es/2012/07/gwt-support-for-mobile-app-development.html
I actually build mgwt and gwt-phonegap and so its kinda hard for me to say that it is the best way, because I am somewhat biased.
But what I can say is that I know many many developers who have built their applications with mgwt and gwt-phonegap and have put it into the play store and the app store as well. The framework works very nicely. Since I am on the GWT Steering Committee I sure hope that I know how to build GWT frameworks, so mgwt should be doing most of the things just right.
If you are looking for other mgwt developers take a look at our mailing list: https://groups.google.com/group/mgwt and feel free to take a look around at http://www.m-gwt.com

I've recently heard about nextInterfaces..
I need to know if any one had an experience with this framework?
What is it provide? (I notice it don't provide mobile-specific features like other frameworks like PhoneGap)
I feel it is simulate some APIs for iPhone? I am not sure...
I just need to know if any one played with it before .. Thanks
Seems to be Java GWT library optimized for Mobile. I am considering using it as it have nice UI, yet still waiting for the GWT UiBinder to be implemented. Otherwise looks very promising.
We have recently developed an iPhone, iPad, Android application with the Rhodes framework and have found it to be painful to say the least. As we are approaching the finishing stages and now testing the app in mobile devices we find more bugs than were apparent in iPhone simulator and would like to change the development direction as it seems most of the Apps even showcased on the Rhodes site are super buggy and not as smooth as they should be.
Can anyone lend any insight on how we may take already developed front-end files with prepped JSON data to apply it to another framework to produce the application. We have learned how the jQTouch framework operates and feel comfortable developing but need to package this into an application.
Rapid development is a key concern as we are approaching a deadline on this project. Note our proficiencies are Ruby, ROR3, JQuery, Modern front-end (HTML5/CSS3)
I'm not familiar with Rhodes, but it seems like Phonegap might be a good solution for you. I'm not sure what your app needs to do, but your skills (HTML/CSS and jQuery in particular) would translate well.
Phonegap lets you create an app for both iPhone/Android, while using the same code. There's some tweaking when setting up your files... but the overall intent is that you're working with the same code (as opposed to having to create two separate apps).
For both iPhone/Android apps developed with Phonegap, you're basically working with files within a folder (much like you would work with files inside a folder on a server). It's a basic group of file types - image, javascript, css, etc. You build like you would for a browser.
jQTouch provides more of a look and feel, in terms of the buttons, UI and animation/transition between sections. Phonegap more or less wraps up all the code, and lets you bundle it as an app for iPhone/Android.
Additionally, if you need to access device-specific functionality like GPS, camera, etc... Phonegap has a nice library you can tap into. Again - same code for both iPhone/Android.
A quick reference to review (to see if Phonegap + jQTouch is a good fit for you) is Jonathan Stark's book: Building iPhone Apps with HTML, CSS, and JavaScript. You may also want to refer to the example files referenced in his chapters, here.
Final note: jQtouch is meant for smaller handhelds. Not sure how well it translates over to iPad, but just an FYI. I know less about Sencha Touch, but it's made by the same folks and might be another approach for larger screens.
I'm about to develop an app for iPhone, Android, and for web too. I think there must be some "standard" way for doing this, in order to reuse as much code as possible.
Which is the best way for doing that? Webservices? (only if the app uses internet) Maybe an API? Another way?
Just for the record, the web application will probably be developed in Ruby On Rails 3.
Thanks!
There are a few cross platform development tools out there that let you write once and compile for multiple platforms. I know I've seen questions on both tool here on SO, so others might have some good advice on these specific products.
PhoneGap

Appcelerator

Barring that, if you are looking at doing native development on each platform, the web services APIs are a good way to go. I've built an App that is heavily data driven, and I built out RESTful services over JSON that do the heavy lifting for the iPhone, Android and Web versions.
There still is quite a bit of work that goes into implementing a feature on each platform, but once I architect code on one platform the hard, creative work is done and it's just porting it to the next platform (Same applies, mostly, to the graphics as well). Since I am coding for each platform individually I do try to take advantage of both code and UI conventions for that platform to give the user a native experience (say building menus for the menu button on Android, something not supported on iPhone). To me that's a benefit of developing for each platform individually, however, it also greatly increases time to market for each version.
Since you're looking at Objective-C, Java and Ruby, 3 completely different languages, there's not an easy way to develop a shared library without using a intermediary layer like those linked above.
Well, all three are different languages, so anything you write for one won't work for the other. An API on a server may be able to get you the same data to all, but its highly unlikely that you'll get any reusable code. I'm doing the same thing, and realize that, so I am just sharing common things such as UI and code-design between them.

What is your strategy for building a desktop-like webapp that needs to be deployed to desktop web browsers and on mobile devices(Android, IPhone, etc)?
A course of action could be to firstly select the best framework for building the part that runs on computers(i.e. not mobile devices). Being a desktop-like app, a good candidate framework is GWT+ExtGWT since it provides:
Java-based development which is much scalable/solid than developing in Javascript via ExtJS for example
Good debugging
Good testability
Next, you'd want to deploy this app on mobile devices too. So how do you go from here? Write a separate implementation(separate from GWT) for Android, another one for iOS(in objective-c), another one for Windows Mobile, and so on?

Related to above, I saw the presentation of PhoneGap which claims you develop in Javascript+HTML and it generates code for all mobile platforms: Android, iOS, etc.
However, PhoneGap is not an option since I don't think it integrates well with GWT and more important, it doesn't generate a native app which can take advantage of features like backgrounding, services, etc(see http://www.youtube.com/watch?v=xHXn3Kg2IQE for why native Android apps are much better than browser-based ones). There may be other frameworks like PhoneGap out there that I'm not aware of though but at this point I only see:
one implementation with GWT
one implementation for Android
one implementation for IPhone
and so on ...
If you are already planning on developing for multiple platforms, it is a good idea to at least consider cross platform frameworks like PhoneGap or Appcelerator. Beyond the fact that you are developing for multiple platforms there are a couple of other important questions to consider.
Do you want a web version as well?
Do you need intensive graphics support?
Do you have loads of money to target multiple platforms?
Do you have loads of time to target multiple platforms?
You also point out two more great questions to consider in debugging and testability. In terms of unit testing, any native platform is very difficult to unit test. Debugging is pretty easy for most native platforms.
Regarding PhoneGap, it is important to know a few things about it.
You can write PhoneGap plugins. A plugin is essentially native code for any given platform that can do pretty much anything you would want to do in native code -- background services, opengl, etc -- and make it accessible to JavaScript in the web view.
There are several open source projects that you might be very interested in such as GWT-PhoneGap, QUnit for JavaScript unit testing, and Weinre for Firebug like debugging.
Hope that helps!
Can someone recommend a good Mobile UI Javascript/jQuery framework that works well with both the iPhone and Blackberry? I'm developing the core app from ASP.NET.
Thank you in advance.
I don't have any personal experience with any of these, but I thought I'd mention a few that I've heard of. It will probably depend more on the features you require for your specific application, to determine which framework suits you best. Also, this is by no means an exhaustive list - the "cross-platform" mobile frameworks seem to be popping up all over the place recently!

PhoneGap
ramp
appcelerator
As it is today, the BlackBerry browser is not very friendly to these libraries. But the upcoming version will support HTML 5, which will allow you to use most popular js frameworks. From personal experience I can recommend Sencha and jQuery.
I would recommend Sencha Touch or Sproutcore.
Sencha Touch is very similar to EXTJS, which a lot of front end developers really like. Check out
http://www.sencha.com/products/touch/
It is probably more mature than SC, and you will have a larger developer base on which to draw. You are gonna wanna try out the demos on that link, on a phone or ipad if you have one.
However, I personally like the strong MVC pattern that Sproutcore enforces. The mobile framework exists, but I don't know of any major clients adopting it, yet. The founder of SC, Charles Jolley, recently left Apple to push his framework; its gonna be big.
BlackBerry has very basic browser.
But for iPhone, you can try jQTouch. Its lightweight and amazing.
