I want to develop a web app using html5, js. One of the feature is to launch device Camera and record video, take a picture and access photo album. Is it possible to access via web app if i develop? I saw in the forums that, it is saying not possible in some places and it is possible in some places. I would like to know, is it really possible to access directly camera and album etc. ?
Please suggest!
Thank you!
It's not possible to access phone camera using Web app, as the "Web APP" typically runs in the browser of device.
Though there are some frameworks (like Phonegap) allows you to embedd your web app into native container. With this approach and added libraries from such framework you can access some of those native API's and Device Hardware.
One Possible solution is,
Create one app and distribute it using app store
using your webapp, you can connect to above app using url-scheme

go to above link, where you can find complete code for it.

I'm creating a website which I would like to be supported on the iphone as well. The site allows users to upload images and manipulate them. On a desktop the user will simply click the upload button to select the file from their computer and upload it to the site. But this will fail on an iphone.
Is there any way for a pure web app which is using php/mysql/js and runs inside the browser to get images from a user's camera roll? Does Apple offer any APIs to make this possible?
No, it's not possible currently - but apparently iOS 6 is going to support image and video uploads from MobileSafari.
(Apart from that, you can ask your users if their device is jailbroken and id so, suggest them downloading Safari Upload Enabler from Cydia).
I'm building a simple web app for iOS that will not be published to the AppStore.
For infrastructure limits (and my boss!) , I can't use xCode anyway to build the app in a native way.
The only NATIVE functionality required by the web app should be a simple "Add to contacts".
I've tried to implement it with phonegap , but it works only compiled under xCode.
Is there any way to "add to contacts" without building an app (using only a web-app )?
Thanks in advance

I don't think there's a way for you to add a contact directly, using only a web app.
PhoneGap was made for this sort of thing, allowing you to access a device's features (like Contacts, Camera, GPS, etc). But if your company's project specifications don't allow for an app... I don't know that there's a way to do this directly, via the web.
If you're building a web app... while you may be targeting iPhones, you're still making it available to anyone with a browser. I'm not 100% on this, but having some way for a web page to directly manipulate a (Mac) user's contacts seems like a security issue.
As a test, I tried placing a vCard on a page, and accessing it via my iPhone. Changing the extension from .vcf to .vcard didn't yield anything (and for some weird reason it prompted me to open the file via Dropbox).
What did work was emailing myself the vcard as an attachment. I was able to view the attachment, which then gave me the option to add the info as a new contact.
I am building a hosted mobile application so I can write once and deploy to many mobile platforms. My plan is to write a native application with a single screen that is a browser that navigates to my hosted application. Of course this is so our application is in the App Store, Android Market, etc.
Is it possible to use the PhoneGap JavaScript so my hosted applications can use local APIs? For example, I would like to be able to upload pictures taken from the camera.
Short answer: no.
More information: PhoneGap: It's possible to use only the phonegap.js and it's functions only in a Website (doesn't want an App only a Webpage)?
Short answer
No. You need to add pctures upload logic in each framework
In addition to what has been answer it will also depend on your application store offering. If you're intending to offer the app in the iPhone App Store, these kind of apps aren't permitted. In the guidelines it states that apps that basically launch a browser or UIWebView will be rejected.
Additionally, you could always create the app as a "home screen" app, that runs without the chrome, etc on the iPhone. Hope this helps.
I have read some post about apps programming for Iphone and Android, but I have one question. Is it posible when there is a mobile website optimized for mobile phones, that I can create apps for Iphone, Android, Win 7 and Blackberry, that only statrts the browser as instance and display the mobile website? What do you think, is this ok? Do you have any ideas or examples for that kind of apps? I mean this is not an app, that should be has access to the hardware of the phone, only web app.
Thanks

This would work.
You could create an app that consists merely of a webview into which you load your content. The content could be loaded over the mobile network or be stored locally.
However most users (including yours truly) strongly dislike apps that merely present a single website to the user, because of the long delays if the content is loaded over the mobile network every time and because the UI is, in many cases, very different to what the he or she is used to from native apps.
Most users fail to see the need for a specialized app just to visit a website which they could as well keep as a favorite in their mobile browser. On the iPhone, you may even add favorite websites as icons on your homescreen, so there is no need for apps presenting a single website at all.
It's not only possible, such things are already done. One example I know of is cookd, a restaurant guide for Vienna. But there are some constraints; for example, cookd requires GPS data for the "Nearby" option; on my Android phone (HTC Legend), this is possible when I open the web page directly in the browser (the browser asks if I want to allow cookd.com to get this info); but the same webpage, running in an application that does nothing more than display the browser component, cannot do that. To fix that, they would have to build GPS reception into the app and forward this info to the browser component.
O'reilly has a fantastic article about this:

This is a little bit directed to iPhone only, but will give you a good overview about the topic and possibilities.
I have a query regarding launching a native application from a link of website on iPhone.
I will explain.
Generally a web based application is used to work online without using any feature of iPhone device (such as GPS, Camera, Accelerometer etc.)
I have a iPhone specific website which performs many tasks online.
Now while keeping all the functionality same, I want to add a feature of taking a picture from iPhone in-built camera.
i.e. when user clicks a button on website "Take Picture", my native application should be launched, which will take a picture and do specific tasks..
How to capture a event of button click which is performed on website?
Should I use UIWebView or Safari?
I know that using URL Scheme we can launch Safari from native application.
But how to achieve the opposite as explained above?
All other functionality works great on website, so I don't want to convert the whole website into native application.
(Otherwise I will have to deal with web services). Only this functionality needs to be added.
Register a URL Handler, then have a link on your site to myapphandle://some.parameters.here/
