Can we create android applications using HTML5?
You can write complete apps for almost any smartphone platform (Android, iOS,...) using Phonegap. (http://www.phonegap.com)
It is an open source framework that exposes native capabilities to a web view, so that you can do anything a native app can do.
This is very suitable for cross platform development if you're not building something that has to be pixel perfect in every way, or is very hardware intensive.
If you are looking for UI Frameworks that can be used to build such apps, there is a wide range of different libraries. (Like Sencha, jQuery mobile, ...)
And to be a little biased, there is something I built as well: http://www.m-gwt.com
Try Sencha Touch. It is a HTML5 compliant framework to build application for touch devices.
Here is a starting point for developing Android apps with HTML5. The HTML code will be stored in the "assets/www" folder in your Android project.
https://github.com/jakewp11/HTML5_Android_Template.git
When people talk about HTML5 applications they're most likely talking about writing just a simple web page or embedding a web page into their app (which will essentially provide the user interface). For the later there are different frameworks available, e.g. PhoneGap. These are used to provide more than the default browser features (e.g. multi touch) as well as allowing the app to run seamingly "standalone" and without the browser's navigation bars etc.
You can use WebView and create a app that put your site inside.
https://developers.google.com/chrome/mobile/docs/webview/gettingstarted
you can use webview in android that will use chrome browser Or you can try Phonegap or sencha Touch
The WebIntoApp.com V.2 allows you to convert HTML5 / JS / CSS into a mobile app for Android APK (free) and iOS.

Want to create an app which can run on both ios and android without modifications.
Cider (http://engineering.columbia.edu/sync-columbia-engineering-team-first-run-ios-apps-android-platform)
seems to be promising. But couldn't find any examples.
Are there any other means of getting this to work? We don't want to maintain 2 codebases for the same app for ios and android.
I am used the following steps to convert
http://www.apportable.com/ please refer this link.Using this sdk we can
directly convert Xcode project into Android project.
I tested this sdk.It is give amazing output.
It is only need four steps for converting.
this is for your reference , in before i never used ,bz i don't knw JAVA.if u need this convert Android to iOS use this link
http://www.androidcentral.com/google-develops-tool-translate-java-ios-friendly-objective-c-code
ok try to develop app in phonegap(cordova) by using html,css and JavaScript programming language
Have a look at Apache Cordova. Supports almost any platform you like and is open source.
http://cordova.apache.org/
Other option would be Xamarin. Has a commercial license for both platforms.
http://xamarin.com/
You can use PhoneGap, you will have one app for platforms other than Android and iOS also.
PhoneGap is a mobile development framework produced by Nitobi, purchased by Adobe Systems in 2011.[3][4] It enables software programmers to build applications for mobile devices using JavaScript, HTML5, and CSS3, instead of device-specific languages such as Objective-C.[5] It enables wrapping up of HTML, CSS and Javascript code depending upon the platform of the device. It extends the features of HTML and Javascript to work with the device. The resulting applications are hybrid, meaning that they are neither truly Mobile native application native (because all layout rendering is done via web views instead of the platform's native UI framework) nor purely web-based (because they are not just web apps, but are packaged as apps for distribution and have access to native device APIs). From version 1.9 onward it is even possible to freely mix native and hybrid code snippets.
The link u provided is an on going research,it will take more than 3-4 yrs before it can come in market,However u can use the existing technologies like
phonegap
titanium .... to do what u want

I am newbie, and i don't know how to create HTML5 based android application.
1.) Could anyone give me some workaround on how to create HTML5 based application for android platform.
2.) What tools/libraries should i use in creating application ?
if possible, then please share the links.
Android SDK enables you to create a web browser app. Just like Google chrome. You can then deploy the App to Google play store so people can download it and Install it on Android phones and tablets.
Jquery mobile is a popular framework that makes it easy to create a mobile web App that can be viewed in a browser.
Put the two together and you have a mobile APP that can be started on the phone just like any other app and it looks and feels just like a native APP.
Once you create your Android SDK webview App you can move the JQM folder in the resources folder and tell webview to load the index page of your web app when the app starts. When you create your first app and get the hang of it you will see its very easy.
Here is a Tutorial.
https://www.youtube.com/watch?v=QRa4yMjoI7c
But JQM still lacks a few things from what native written apps can do but its getting there. The latest version 1.4 is quite good but future versions will be even better and have more abilities.
The good thing about JQM Apps is that they can be viewed on any browser so it can reach more people and more platforms.
If you want to access some of the mobile phones inbuilt devices such as the camera or SD card with JQM then you need an addition to the Android SDk called Phonegap.

There are hundreds of sites now which allow you to create apps for iOS & Android on the fly. Am completely lost on how they are able to achieve this online. Are there any services which help compile the code?
Can anyone help in giving an outline of the full process? They primarily look like mobile webapps placed in a virtual browser.
Any thoughts on the flow will be helpful.
Sample sites:
http://www.theappbuilder.com,
http://www.shoutem.com,
http://www.appypie.com,
http://www.appsbar.com,
http://mobiappbuilder.com
All of them support native apps. How do they do this?
UPDATE
Thank you for your answers. But am not looking at creating apps. Am looking at creating a service which creates apps. A service which allows creating mobile webapps is no issue at all. But how do the above companies allow creation of Android & iOS native apps on the fly? How do they do it i.e. what is the technology/flow for that?
They are HTML5+javascript based like crossplatform frameworks like PhoneGap for instance.
You are exactly right.
The trick is in the word native. A native application in this context doesn't mean an application written in Obj-C or Java. They have a small native core, mostly only to display a web view and they dynamically generate HTML pages for it. They can run their own web server on the device or use HTML prepared beforehand or load it from some internet source but most of the functionality is done by HTML(5).
Depending on how advanced the framework is, the native core is bigger and can provide some of the native features, e.g. access to filesystem or notifications. If a web server is running inside the application, then the server can provide the advanced functionality using some HTTP API.
The UI is usually done in HTML (+ CSS & javascript) but there can be also some native components.
The biggest problem is usually the look & feel which is not native (usually CSS mocks up the native UI), performance and memory problems.
It's good for small applications, it's terrible for bigger applications.
Once you have the framework and the user-generated functionality (UI, images etc), it's trivial to compile it using command line tools (e.g. ant for Android, xcodebuild for iOS).
Edit:
In other words, the native framework contains a web server and a web browser. The application is only a resource that is inserted into the framework. It's exactly the same as when you are creating a normal web application. The only difference is that the server side data is stored on the client, too. Depending on the framework, the server side scripts can be either compiled or interpreted.

I want to develop a local web app using mobile jquery.
what is the way to open the app using icon in iphone and in android?
Thanks,
it really depends on your project depth.depth in sense of complexity.its always suggested to develop separate for each platform.evaluate your needs carefully.
if the application is simple enough then you can go for third party apis
PhoneGap and Sencha Touch are good options.
but still you might find yourself restricted by a third party API if you need to add new functionality in the future.
What i understand from your question is you want to create a iOS and Android app using html, jQuery etc. There are tools such as PhoneGap, Titanium and Sencha touch. Using this tools you can create a mobile applications with help you HTML, jQuery. However, this apps won't have same user experience as it'll have with the native apps. Also, just think about future releases of your application. If Apple or Android adds new features to there OS it'll be definitely take sometime for above third party API to implement them
Also, apple clearly rejects app which acts like a website. So, you'll have to be careful with this. I'd suggest you to go for native app development. It'll provide you flexibility.
As far as I know, you can't get anything onto iOS without an Apple Developer account. As for Android, you can check out PhoneGap. It also has iOS, but it won't build without a valid apple dev account. Does that seem to be what you're looking for?

I would like to know if I can use phonegap to create a simple augmented reality application.
Can I create an augmented reality browser with phonegap to show pois at camera of Android phone?
Anyone know some references or simple examples?
PhoneGap is not just a native wrapper of a web app. Through the PhoneGap javascript APIs, the "web app" has access to the mobile phone functions such as Geolocation, Accelerometer Camera, Contacts, Database, File system, etc. Basically any function that the mobile phone SDK provides can be "bridged" to the javascript world. On the other hand, a normal web app that runs on the mobile web browser does not have access to most of these functions (security being the primary reason). Therefore, a PhoneGap app is more of a mobile app than a web app. You can certainly use PhoneGap to wrap a web app that does not use any PhoneGap APIs at all, but that is not what PhoneGap was created for.
if there is something u want to use in your app that phonegap does not provides then you can create a native plugin and use the functionality in your app.
thus phonegap can be used to create apps that can match 100% with the functionality provided by a native app. you can give it a try to create your app.
You can use the Wikitude AR Phonegap Plugin, you can do almost everything with that using JS, HTML5 and CSS3.
