I need to implement an pdf viewer in javascript/dojo mobile, which have all controls and opting for pspdfkit.
Does pspdfkit supports for native js / dojo. Founf it only for native iOS, android and cordova plugins.
Please suggest on this.
Head of PSPDFKit here.
We do offer SDKs for PDF viewing, editing, form filling, digital signatures and indexed full-text search currently for both iOS and Android. We offer iOS since 2011 and in early 2015 released our first version of Android - now both SDKs are mature and a whole team is working on them.
For Cordova we have wrappers for both platforms:

I am developing a cross browser plugin for document viewing (.pdf, .doc, .xls, .mht, .tiff, .dwg). It needs to be a plugin and not the extension. Whatever i try to search takes me to the links for extensions and not for plugins. I found NPAPI as cross platform plugin architecture but soon found out that major browsers have planned to depreciate and stop the development support, Chrome is one of them. I have been searching from last 3 days and finding myself in no man's land.
I intend to develop the tool as a business requirement and not use some already developed software tools like quickview. Please provide some good links to the cross browser plugin development. A little help will mean a lot. Thank you
The only truly cross-browser technology, supported by all the major browsers, are standardized or standards-track web technologies. If you want something that works in all browsers, you'll need to develop using the technologies that browsers are designed and intended to support.
The reason you aren't finding any resources for doing what you describe is that there's no way to do it.
I intend to start an iphone/android project with the titanium SDK for mobile. Do you know what are the main feature-wise pitfalls to avoid ? what sort of features will be very hard or impossible to achieve ?
I understand that there is a plugin system to circumvent these limitations. Do you have information on that ?
Thank you for your help,

I have yet to find a particular piece of Android functionality that is missing from Titanium. Not sure if widgets are in the current 1.5.1 mobile release or are coming in 1.6. In any case, the coverage is pretty decent, as you will see if you try out the "kitchen sink" app.
But here are some things I find lacking:
Titanium's Android support is still much buggier than iPhone support. For instance, I can't get global events to work properly--that's pretty important functionality.
documentation isn't complete; the API docs are skimpy
you're on your own; Appcelerator employees don't bother to answer questions online (even when they concern obvious bugs on their end), unless you subscribe to a support plan
That said, I've found developing Android apps with Titanium to be much more enjoyable than dealing with the Android SDK!
I agree with most of what #Drew stated above.
The API documentation is for the "most part" pretty complete, yes there are a few missing pieces, but hey the framework is free, they push releases pretty frequently and all the source code is available for you to go through yourself. You also have full access to the Continuous Integration Builds
I believe the 1.6.0 release has addressed additional issues with Andorid support, there is also a bug tracking system for you to investigate and report issues.
You are not on your own any more than with any other similar framework... Occasionally employees will review specific issues that show up in the Q&A Forum but the forum is very active and there is tons of community support. I would be surprised if you could write most of an application from just cutting and pasting from the Q&A questions and you will find the rest in the Kitchen Sink Example or Tweetanium Example Projects.
You asked about a plugin system. Titanium offers the ability to develop your own custom native modules.
The Titanium's Module Developers Guide (PDF) isn't the best, but it will get you started.
As Drew said, many of the Titanium's Android support is buggier compared to iPhone.
Titanium is meant for people who never wanted to learn the native iphone and Android programming. If you know to develop applications using objective C and you wanted to develop applications for iPhone then don’t even think of Titanium, the same case applies to Android too. Only if you are lazy to learn a language, you can opt for Titanium.
1.The size of the Application is a big concern here.
2. Some of the features in Android which was shown to be working in developer reference were not working. Even after being filed as bugs, they were not updated in developer’s reference that it works only in iPhone. For example, “focus” events of the window is handled only in iPhone and never in Android.
To get to know in details, the problems Titanium can bring you read the following post:

Technology to write iPhone, BlackBerry and Android phone at the same time?
Edit - guys, we need one more vote to close this. This question is a dup (read the comments)
I've heard that Apple banned such tools. Ok, so Apple lifted their ban in September. Still, the question holds - is there a sane way to develop apps to these two platforms without writing nearly everything twice?
Is there something I'm missing, or is the current state of affairs really that every company that develops a cross-platform legally has to maintain two code bases?
Apple reversed their ban in early September after receiving some pressure from the FTC and EU. However, unless you plan on using a third-party tool such as Adobe Flash Pro CS5 (I believe you can create AIR apps that will run on Android this way, as well as the much publicized iOS functionality), you'll have to maintain two codebases anyway, as Android apps are written in Java and iOS apps in Objective-C, two vastly differently languages with vastly different APIs.
You can always use standard HTML5 technologies to make a pure web app. Apple has two tracks for apps: native apps through the App Store written in Objective-C, or web apps that have only the restrictions of the underlying HTML5 technologies.
If you don't like pure web apps you can even merge the two and make a custom app that displays heavily customized web-like content in an embedded browser view (UIWebKit on iOS). Android and iOS web browsers frameworks are from WebKit and very close in features/appearance/conformance.
Instead of starting from a viewpoint of "I can't do X on Apple's closed iOS" start with "Can I do this in any supported application technology, even if its web-based or a web app hybrid, available across all platforms?"
I've done some research on this recently and have found a few companies that can to do this for you.
Appcelerator Titanium Mobile. They make a product that allows you to write your code in Javascript. I've found that the business logic, like networking, files, etc are write once, but the UI has quite a bit of if(android) else \iphone logic to get right. Apps will look native.
FeedHenry. They are more of a HTML based solution, but have a broader support of devices. More than just iphone and android. The sdk is still pretty early, and work can only be done in their special ide that is web based.
Phonegap. A javascript/css/html based framework that targets the iPhone, Android, and the Blackberry.
There are plusses and minuses to all of the solutions. Depending on your app's complexity, it may be a good decision to pick a platform like those to develop on. Coding an app could be much faster if the features they support are right for your app. Right now, it seems that they are all in early release phases and don't support a full toolkit that a developer would be used to, like a debugger, full IDE support, etc. Also, many of them build to a lowest common feature set, so you may not get all of the new release features as they come out, you would have to wait for a particular version of the platform to be released in order to have them.
XMLVM: Android to iPhone
XMLVM can translate your Android code to Objective-C for iPhone. But as what I know you still need a Mac to compile the iPhone application.
Android has the NDK (native dev kit) to allow C and C++ code to be included in APKGs and called from Java via the JNI. Apple's toolchain will also deal with both; the code that will be different will be the platform interface code, mostly in Java on Android and ObjC on iOS.
This is only useful when the bulk of your application is in C or C++.
An alternate would be to go with MonoTouch and the upcoming MonoDroid, if everything works out you could basically code C# on all platforms including of course Win7 Mob.
It looks promising but haven't tried it myself yet.
In September, Apple lifted some of the restrictions in the iOS license that had made it difficult to do cross-platform development. See this press release. I'm not familiar with the details of the current license, but you can get a copy through their developer program.
Another possibility that would be the Rhodes framework, if you like MVC, ORM, and Ruby.
take a look at the System.getProperty() values with android the vendor shows as The Android Project. I haven't looked at the iPhone or the IPad since I don't have one but hopefully they have something changed for their's too. But this will only work with java that I know of.
As i am going to develop mobile web app for all devices. My question is, if the browser is not support html5 kind of stuff, Whether Sencha will support HTML4?
Thanks in advance,
srini
[sencha person] #Sri. Sencha Touch works on Android 2.1 and Apple iOS ONLY for release 1.0, and will be supporting RIM, Nokia etc. devices as they add modern browsers to their phones that can support javascript and CSS at reasonable performance and correctness.
[Update: We've tested the new RIM Blackberry Torch, and will be adding it to our support list - probably in release 1.1]
A majority of existing phones (Nokia featurephones etc.) are not capable of running a web application because they lack javascript performance, CSS support and even full HTML capabilities. In our (opinionated) view, the only phones (today) that can support a proper web app experience are Android 2.1+ and Apple iOS.
Well, I cannot give a definitive answer, but given that ExtJS (the name until recently) still supports Internet Explorer 6, I'd guess so. They are double-licensed as GPL + proprietary license, so cannot just drop support for something outdated since that would piss some/many paying customers.
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, visit the help center for guidance.

Have any well-documented or open source projects targeted iPhone, Blackberry, and Android ? Are there other platforms which are better-suited to such an endeavor ?
Note that I am particularly asking about client-side software, not web apps, though any information about the difficulties of using web apps across multiple mobile platforms is also interesting.
The HTML5 standard has support for releasing stand-alone HTML5 apps. Essentially a HTML5 app is a bundle of HTML5, JavaScript and CSS files that will run stand-alone in the browser of the desktop or device. You can distribute them like any other program, including selling them on the iStore for the iPhone.
The support for this is patchy at the moment but is likely to improve tremendously in the next year or two.
Google for HTML5 apps for information and resources. A good introduction to HTML5 is the online book "Dive Into HTML5" by Mark Pilgrim. This is a work in progress, but sufficiently complete to be useful.
There are 2 [newish] solutions to exactly this issue:
rhomobile
and
phonegap
I think there best chance for cross-platform mobile success is the Web. Just write a very simple Web application for what you want to achieve. It should work on the Nokia S60browser, Iphone and Android.
That's already a lot of mobile devices...
Appcelerator, PhoneGap (acquired by Adobe, plus it's now standardized as Apache Cordova), Intel XDK (formerly called appMobi) and Rhodes (acquired by Motorola Solutions) are all open source and create hybrid apps (natively packed with html ui, with the possibility to add some of your native controls).
If it's a game, your only professional choice for a free engine that can be used for commercial development is Unity3D. For 2D games, cocos2d-x is also available. Additionally, Vuforia can be used for AR and LiquidFun for physics.
XMLVM (via Coke and Code) and EdgeLib currently seem to be the most mature options. EdgeLib is aimed primarily at game developers, and according to Coke and Code, the XMLVM developers are difficult to contact.
The iPhone uses Objective C, the Blackberry Java SE with RIM functionality and Android another custom version of Java. I could possibly see how you could combine the latter two but there is no functionality (without jailbreaking) of running Java applications on an iPhone.
The best bet I've seen so far is something like Qt that will run on Windows CE, almost certainly shortly Symbian, some Java platforms and the three major desktop OSs.
redfivelabs have implemented the .Net compact framework for the S60 platform
Titanium Mobile from Appcelerator looks interesting. You develop your app in HTML & Javascript and upload to their server where it is compiled into a native application of the target platform (currently iPhone & Android)
For the iPhone there's currently no such notion as Open Source as the Apple iPhone SDK NDA forbids publishing code. They also forbid posting code on any non-Apple site or even non-Apple discussion forums on iPhone development. As soon as the NDA expires (will it ever?) we'll start having Open Source iPhone apps.
Suprised MoSync hasn't been mentioned here already.
Update (2014 January - present): the project is abandoned.
I started to use a really cool cross-platform SDK called EdgeLib. It allows you to use a simple API and you can compile your projects to a variety of platforms: Windows Mobile Pocket PC, Windows Mobile Smartphone, Symbian Series 60, Series 80, Series 90, Symbian UIQ, Gamepark Holdings GP2X, Gizmondo and Windows desktop.
I know iPhone, Blackberry, and Android are not on that list but the developers mentioned that these platforms are on their roadmap.
EdgeLib looks promising and has an iPhone beta announced but not open yet.

Well BlackBerrys don't really have Java SE, they have Java ME, with a lot of additional librarys provided by RIM. Same goes for Android. The only cross-platform apps you'll ever see on mobile devices are probably written in strict Java ME, which runs on most devices. However, just like JavaScript between different browser, Java ME has is quirks across different devices, so source code changes may be necessary.
