I recently found in news that KaiOS has been used in 4G Volte Enabled feature mobile phones. I was wondering how to create apps for KaiOS. Any help on creating apps for KaiOS has been greatly appreciated.
You can find the kickstart here https://developer.mozilla.org/en-US/docs/Archive/B2G_OS/Firefox_OS_apps/Building_apps_for_Firefox_OS but as KaiOS is B2G forked i would still suggest you to go to kaiOS official website to check the proper flow for the application development.
Below are the series of steps you need to go through if you don't want to get stuck in between of development:
First you should understand how applications actually work in kaiOS environment and for that you need to first understand the architecture for that. You can give a read to https://developer.kaiostech.com/introduction/architecture for more understanding.
Then comes setup for your application which you will find here at https://developer.kaiostech.com/environment-setup . Mozzila firefox shift+F8 will open the webIDE where you can see your devices connected but for that you should have proper drivers installed for your phone. You can use firefox emulator 2.2 (stable) as well for initial start.
Now its time to have your first application onboard to kaiOS . You can make your application in any of the client specific JS like angular , react or even plain javascript but the important part is to have manifest.webapp in root folder for compatibility.You can give a read to https://developer.kaiostech.com/first-app.
You are able to see your first application on your phone !! Now the real pain arrives when it comes to navigate through the application by keypad but thanks to naviboard library which will do this work for you to align your navigable items and navigate through it by simple API’s. You can find the library at https://github.com/amanboss9/naviboard.
When you are done with navigation part of feature phone, you can go through and develop as much as you can as if it is a web application and can develop a lot of things.
Check the sample project at https://github.com/amanboss9/kaios-angular-app. This Boilerplate can save lot of time when it comes to setting up everything from scratch.It included Angular1.6, naviboardJS(For auto handling navigation part of your application) and Gulp.
KaiOS is based on Mozilla's open source B2G OS. The apps are built purely with HTML/JS/CSS stack and any web application/website that is mobile friendly can be an app with just minor modifications. You can use the inbuilt webIDE to build apps for Mozilla OS, see more here.
https://developer.mozilla.org/en-US/docs/Archive/B2G_OS/Firefox_OS_apps/Building_apps_for_Firefox_OS/Firefox_OS_app_beginners_tutorial
I used to build apps for Firefox OS before it was dead lets hope to see whether it's reincarnation succeeds.
I will try making apps when I get my hands on the Jio Phone and will update here.
Update:
KaiOS has released a newly updated their website with a new IDE called Kaiosrt which is much better and actually works.
KaiOS is a B2G OS forked from Firefox OS.
You can use Angular/React/Jquery or any JS lib/framework to develop apps on Kaios
Packaged app should have all js/image/html/css file packed locally, External link reference in index.html will not work. Blocked by default- CSP policy.
Mobiles (JioPhone/Nokia Banana phone) with keyboard needs to handle its own key events, Refer Kaios Sample app
This is in the FAQs of KaiOS offical website:
Can I develop apps for KaiOS?
KaiOS is a curated platform for apps and we are working closely with
app developers to provide the best experience for our users. At the
moment we are not accepting submissions into the Store, but will do so
in the future.
(https://www.kaiostech.com/faq/#question-12)
Guess you could leave your contact email there and will get updates in the near future.
KaiOS have officially launched the KaiOS Developer Portal.
It's got everything developers need to start building and distributing KaiOS apps.
Furthermore, build your first app with JavaScript (Vanilla), React,
Vue.js and Angular with code examples herein. Then, testing your
apps with WebIDE or Simulator.
Tools and resources include:
A guide to building your first app, with sample code, reference guides, and software development kits (SDKs).
Instructions for ENV setup to configure your development environment.
A simulator running Gaia and web apps in a Gecko-based environment.

Let say were starting a website from the ground up and want to also create apps.
Could you just create the website with a REST API's and have it work on browser and PhoneGap? Would there be a conflict with Cordova plugins you may use?
So the design is responsive and its all HTML, CSS and Javascript and connects to a REST API (log in, reg, messages, db calls, etc) for the browser website and apps.
This way you can use the same code for everything and can still use some of the great Cordova plugins for the app to make it more flexible.
Would this work?
I posted this answer else where but I think it is relevant here.
Unfortunately for your app to pass Apple App store approval it will have to provide some basic functions and display correctly without an internet connection. This means at a minimum, if you plan to generate content on a server you will probably need the Cordova plugin for network information:
https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-network-information/
I would make sure you are familiar with the Apple Human Interface Guidelines:
https://developer.apple.com/ios/human-interface-guidelines/overview/design-principles/
You will probably also need to bundle any JavaScript. Apple is very picky about apps that download code (this can include JavaScript).
This is a section from the iOS developer Agreement.
3.3.2 Except as set forth in the next paragraph, an Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exceptions to the foregoing are scripts and code downloaded and run by Apple's built-in WebKit framework or JavascriptCore, provided that such scripts and code do not change the primary purpose of the Application by providing features or functionality that are inconsistent with the intended and advertised purpose of the Application as submitted to the App Store.
Another big concern is performance. How will your app handle a poor 3G or even 2G connection? Do you need to cache the responses from the API and only download them if they have changed on the server?
If a user is browsing your website on a browser they know they need an internet connection, if they are using your app they want it to work when online and offline.
Edit
Apple commonly uses this reason for rejection for website only apps.
We found that the experience your app provides is not sufficiently different from a web browsing experience, as it would be by incorporating native iOS functionality.
While your app content may differ from your web site or other existing sites, the experience it provides does not differ significantly from the general experience of using Safari, as required by the App Store Review Guidelines.

I am Phonegap/Cordova developer, I plan to move to new technology. I am a little bit confuse that which is best for mobile application development and why.
Really, it depends on what your application requirements are. From my experience, if your application requires a lot of hardware resources, don't use cross platform options, not even Xamarin. I would use native approach in that kind scenario. If your application is a lot like a mobile friendly web application and you are pressed by deadline, I would recommend using Hybrid approaches. Within hybrid approaches I would say use ionic for the following reasons.
Welcome to the Ionic World!
Free, Open Source, Constantly growing and Great documentations
Its on top of cordova. So you will have access to hundred of cordova plugins to achieve native functionality, i.e. access to native APIs.
The power on AngularJS comes built in with the framework.
Touch Optimized UI, removes normal 300 ms delay from webview on touch!
MV* Pattern
Built in CSS components and Ionicons
~ 100% code share
Cloud app reports
No special SDK required
Available from NPM
Great with testing
Scalable
Check Ionic Showcase for the top apps built on Ionic.
Check Ionic vs other contenders.
PS, I haven't spent time on Sencha and its mainly commercial. I could not find its source code on Github. Sorry Sencha!🙁
Both Ionic and Sencha run on Cordova but seriously, Ionic has done terrific job and I would recomment it anyday.
UPDATE
Check out NativeScript and React Native. Both of them deliver native UI rendering (unlike Ionic and Sencha) and look promising. They are also backed by Telerik and Facebook with React being one of the most starred repo on Github. Check this article by Nic Raboy.
I don't have an Apple computer, I just have an iPhone and some knowledge about language development. I want to create my own app for my own use, just for fun! I don't want to pay Apple for a developer account. I just want to develop my app and put it on my iPhone. I can either develop on Linux or Windows. How can I do that?
If you want to develop on an actual iPhone, you'll need a developer licence. To developer apps natively you will need a Mac running XCode.
There's lots of HTML5 libraries for making apps using javascript though. Maybe try out Phonegap or GameSalad
At the minimum you'll need to have OSX (Mac Operating system) to run Xcode/iphone emulator, you wont be able to do this without OSX.
EDIT:
You may be able to develop it using phone gap: http://phonegap.com/
You'll have to do testing on an adriod emulator, but I believe phonegap builds the app in the cloud. Good luck.
You can develop an app using adobe AIR or adobe Flash. Check out FlashDevelop for a free solution for making flash and air apps for everything from windows to android to iOS.
For a somewhat detailed tutorial on how to actually export an AIR project from FlashDevelop so you can install it on an iOS device, see:
http://www.codeandvisual.com/2011/exporting-for-iphone-using-air-27-and-flashdevelop-part-one-installation/
and FYI, this is not JUST for jailbroken iOS devices! :D
Native iOS applications can only be built in Xcode (which can only run on a Mac), and you need a developer membership to deploy those on an actual device (which costs about $100 a year). So, that’s the caveat: You can’t make native apps.
However, native apps aren’t the only option! There are two other approaches.
One way is to make a web app. These days, web apps can do almost everything that a native app can do (even access the camera). Unless you’re building something specialized (like a video editor, for example, or a game that needs to work with Bluetooth game controllers), you can probably make something as a web app. Years ago, I wasn’t happy with the flashcard apps on the market and wanted something custom but super simple to help me study JLPT vocabulary. At the time, I also didn’t have the money for a developer membership. I made it as a web app, and it worked great!
If you’re making a web app, you’ll need someplace to host it. There are lots of options. For example, the free tier on Firebase is plenty for a personal-use web app. You also might want to consider building the app using client-side scripting (like Javascript) so that you can host it statically, which will allow you to tell iOS to cache it so you can utilize it offline (Google “HTML offline manifest” for details).
The other way, if you have a friend with a developer account, is to build your app using a cross-platform framework like Flutter, where you don’t need a Mac to develop and test it, then ask your friend to make it for you. You’ll need to rebuild periodically (I think once a year) because your provisioning profile will expire.
If you use a framework like Flutter that can build both native AND web apps, that gives you the ability to run natively (if you have access to a Mac) or host it statically on someplace like Firebase Hosting (if you don’t).
I am creating my first native phone application using dreamweaver and phonegap build service, one of the most important features I need is the ability to send push notifications. That being said I am having a hard time finding a tutorial on integrating xtify with an app built in dreamweaver. any suggestions? All the documentation on xtify assumes I am building the program in phonegap. First thing you need to understand is that I am not a programmer, I work for a non profirt organization and this is just part of my job here.
Dreamweaver uses Adobe PhoneGap Build which packages mobile apps in the cloud. They don't support custom phonegap plugins (like Xtify) yet but they are working on it. Details here.
From the website:
Right now, you cannot submit your own plugins to PhoneGap Build and
have them included on our system. We are working on the infrastructure
changes to allow this support.

It started one day while I was using my iPod Touch: wouldn't it be cool to have XXX function (from our internal desktop application) available on the iPhone as an native app.
I had that idea because (A) I think our current bulky desktop internal 6+ years old application suite needs a major face lift, and (B) instead of continuing our waterfall development methodology, which usually resulted in a project canned after tens of people spending months on something that no user cares about. I hope that we can start doing lots of tiny projects with 2 week iteration cycles using Agile methodology.
Oh, I also want to find an excuse to use XCode in the office.
After researching, I found out that pretty much NO COMPANY does iPhone native intranet applications because no company wants their internal development needs to be controlled by Apple who tends to kill cool apps like Google Talk. Since our company is ultra concerned about security and safety, the phrase "using a jailbroken iPhone/iPod Touch" is the same as saying "please fire me".
So I came up with plan B: using ComponentOne iPhone Studio to do a iPhone optimized intranet web application. I spent 2+ weeks and it is about finished. My supervisor seemed very excited about it, so hopefully we can turn it into a long term project.
My question is: have any of you tried writing an iPhone application (either native app or web based app) for your company's internal use, and what are the technical and political challenges?
I've written three internal applications (native) for my company.
We are able to use ad-hoc distribution (less than 100 users ; do not qualify for the 500 person enterprise program).
It's been great. The execs love it, our salespeople are using them like crazy. A few new customers have already been credited to being impressed by our tech and coming on board when they saw our apps.
Win-win-win so far.
We've talked about it some at my office, but that's as far as it's gone. The Enterprise developer license allows you to control the distribution of your app within your organization, not Apple. The AppStore isn't involved at all.
If you write your web applications well it is very easy to add an interface for most mobile devices not just iphone.
We use things like: intranet.domain.com/application/mobile/
We always create our web apps with layers of functionality so that the UI side is easily switchable. My favorite at the moment is MVC style. This way you just have a UI designer work on the mobile interface but all the underlying business logic is the same which ever device you are using.
I would also still love to write native iPhone apps for our systems as they are just much cooler :-) Damn you Apple for not allowing us.
I build all of my iPhone app as we apps using ASP.NET. ComponentOne has Studio for iPhone which lets you build ASP.NET sites that look and behave like native iPhone apps. It's a great solution for Microsoft developers like me who do not have access to Apple machine or Dev Kits.
I used it to build a mobile version of our website that calls the same class library our main website does. This is my favorite part of the concept, using my existing model.
