I've been asked to create a Samsung Smart TV offline App but I really don't know what it means to Offline Application.
The client said me
The app has no GUI. It's not like a regular app. The TV will be
pointed to a URL. That URL has specific Samsung TV instructions to
download the files and when the TV has it, it will open the zip and
display the content as required.
I've setup the development environment and have studied about Samsung AppsFramework and learned how to start an application but really confusing about the offline Application.
Could anybody please make me understand that what the client does exactly want?
Thanks
What the client wants in my opinion is an app that can work on the smart TV without having to connect to the internet.
It would obviously need to connect to obtain the download files, but once the app is installed it will have offline functionality and not need to connect to the internet to run.
Have a look at http://electron.atom.io/ to build cross platform applications like this.
It is really difficult to say what they mean by offline as we dont have a brief. But offline generally refers to an app that has everything in the initial download. Example, a dictionary app will have all of the words and definitions in the download so they are always available even if the device is not connected.
Hope this helps
Samsung API provides interface for reading and writing files so you can download and store something for later offline use.
Alternatively you can use localStorage API.
The app has no GUI
This part is strange. Launched app occupy whole screen. You need some use-case description from client. Find out what problem is your client want to solve with this app.

I am trying to write a program in Java that can connect to an iPhone that is attached to a computer via apple USB cable and view its files. I have not found anything like this online and have been wondering if this is even possible. Any suggestions?
iOS is problematic because of DRM. Android is also moving in that direction making standard file system browsing difficult so I doubt it would be possible to view arbitrary files on the device.
Codename One allows you to build a Java app that will run on the iPhone itself which might allow you to access some data. However, apps running in the device also have restrictions and can't access the full file system only their own.
I've spent the day googling all the leads on developing iphone apps on Windows and apart from buying a mac the most suitable route seems to be Phonegap. I cannot find out whether Phonegap gives access to all the native functionality. For example I want to access and manipulate the address book contents. I also want to be able to send text messages programatically and intercept and examine incoming text messages. It would be helpful if someone could confirm whether this can be done with Phonegap.
My understanding is that Phonegap is based on webapps but I am assuming that an app developed with it can run offline for operations that dont require internet access.
Even using Phonegap you will still need access to a mac to actually build your iOS application. This is a restriction that Apple has in place, and to my knowledge there is no way around it.
Phonegap uses a UIWebView to display your application built using HTML, CSS, Javascript etc, but this does not mean that an Internet connection is required for the app to run (so offline apps are definitely possible).
With regards to Phonegap's functionality, details of the Phonegap API can be found on their website. Specific to your needs, I believe phonegap provides access to the device's address book through the contacts API:
http://docs.phonegap.com/en/2.3.0/cordova_contacts_contacts.md.html#Contacts
I don't think Phonegap provides the ability to send SMS messages itself, but many people have developed extensions to add extra functionality to their applications through plugins. The majority of Phonegap iOS plugins can found at the following GitHub repo. The plugin I think you require is the SMSComposer:
https://github.com/phonegap/phonegap-plugins/tree/master/iOS/SMSComposer
I have tried looking for some answers but could not get anything concrete from the other questions in here.
I am looking for an answer to these two questions:
Using PhoneGap, if I create an iPhone web app, can I use it as
plain web app (i.e. without using iTunes to deploy it)? Just via a
web url?
Using PhoneGap, can an iPhone web app check for wifi
connectivity? i.e. If wifi/3g is available, if wifi is available,
can it scan for ssids.
Thanks for any help in advance.
You can create host the web app on your own server (or local). Then it is accessible via web url. If you want to use it as a normal app (there are differences - phonegap uses few native plugins for better experience), then you must have a developer license from apple and then deploy it to your device. Otherwise you can only use the simulator. You can also use Safari + USB to debug your app using the browser.
It is possible but limited. Only certain functionalities are available. Check out the following plugin for cordova (phonegap):
cordova-plugin-wifi
Good luck!
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
Nik
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:
http://building-iphone-apps.labs.oreilly.com/
This is a little bit directed to iPhone only, but will give you a good overview about the topic and possibilities.
I was wondering if I could access the iPhones Core Location framework over a website?
My goal is to build a webapp/website that the iPhone would browse to, then upload its current GPS location. This would be a simple site primary for friends/family so we could locate each other. I can have them manually enter lng/lat but its not the easiest thing to find. If the iPhone could display or upload this automatically it would be great.
I don't own a Mac yet (waiting for the new Mac Book Pro) but would like something a little more automatic right now. Once I have the mac I could download the SDK and build a better version later. For now a webapp version would be great if possible. Thanks.
Why not simply use W3C GeoLocation API available in mobile Safari? This will work on ipod touch as well (suburb precision).
It's literally 10 lines of code and the javascript will work without change on Firefox 3.5. Far easier than scrape some third party website.

iPhone App store
While this may not directly answer your question, there are quite a few iPhone apps that already do this kind of thing with GPS. Instamapper is the first one I pulled up from the app store, but I'm sure you could find something to fit your needs.
I'm pretty sure you can't do what you want directly.
The best idea I can come up with is to "reuse" an iPhone app that records location and makes it accessible on the web. Take Twitter for example. If I'm not mistaken, Tapulous' app Twinkle will grab your location and post it to your Twitter.com user profile. Here's an example of what that looks like:
From your webapp, you could then scrape the user page for each person whose location you're interested in. It's a pain in the butt, but like I said, this is the best I could come up with.
Again, if you don't want to mess with Twitter, there may be other apps out there that do this as well, but I don't personally know of any. Good luck.
We built a really thin iphone client app that simply calls a predefined .js file on our site. Works like a charm.
