I'm trying to figure out a way to create a real-time chatting app with Xamarin and some kind of backend technology. How can I do it?
I have a better solution. The above-mentioned technologies(buddy SDK & SignalR) will require you to integrate and handle everything by your self. Instead, you can go for CometChat SDK, which has real-time chat along with Audio/Video chat functionalities. Also, you can use its ready-made UI inside your application. It is the easiest & quickest way for you to make a real-time chatting system. For more information on CometChat you can refer to the following link:
https://developer.cometchat.com/docs/xamarin-forms-quick-start
As mentioned by ChristiaanV, SignalR is the way to go.
The Performance is great with Xamarin, we delivered more than 150k messages within 2 hours without any problems regarding the connection.
With Azure Mobile App and ServiceBus, you can easily scale out your backend, as described here http://www.asp.net/signalr/overview/performance/scaleout-with-windows-azure-service-bus
Have a look at SignalR, it's a good and easy to use framework to do realtime 'things'. They also have a Xamarin Component which is free to use.

Please note that I personally don't have experience with using it on mobile devices, so I can't tell you anything about how it's performing battery / performance wise.

I apologise in advance for my fairly broad question, but I am just looking for some general guidance on how to approach the issue below.
I am developing my first app for android/iOS with Xamarin Forms. I need to do reminders(notifications) for medical use. As this is scheduled in advance I would just use local notifications.
I have been browsing through the Xamarin documentation but I find it very confusing and lacking proper examples.
I think I have to use dependency services as there is no xamarin.forms implementations as far as I can tell. What is the best way to go about this and does good examples exist for local notifications?
Also for the moment my application stores all data online, will it be possible to store/schedule these notifications with something like an event id for reference? I would also like to be able to perform actions on the notifications(from the lock screen), but this can wait.
I'm currently working at a project to develop an App for firefox os similar to: http://www.zoobe.com/.
So it's basicly a hosted app, where you can choose a 3D-character. Then you have to make a picture for the background and record your voice on the phone. A Video will be rendered then and the 3d-character will speak the recorded message for you!
So my generell question is: Does anybody know, if its possible to develop such complex app for firefox os at this stage?
I've read, that all the APIs required for the project, like camera API and so on are already working.
I would implement the data-flow between server and client with node.js.
I would be greatful for any evaluations, tips and help.
There is no sound recording API yet, so I fear you will have to wait for it to be implemented for this kind of app to be possible. You can track the work on this API at https://bugzilla.mozilla.org/show_bug.cgi?id=803414
All,
I'm writing an extensive iPad application with a Core Data based data model. Because the app requires a lot of user input / typing, I would also want to make the functionality available as a web page, so that users can use standard PCs to key in some of the data.
I'm not particularly worried about the UI for that web app, but I do want to re-use the application logic and Core Data model that I'm using for the iOS app, so my preferred approach would be to expose the functionality as web services on a Mac (using the built-in Apache web server, most likely), using XCode for MacOS.
(1) Are there any existing XCode-based frameworks that simplify the generation of web services?
(2) Am I missing something obvious i.e. is there a better approach to tackle the problem "exposing iOS functionality through a web environment"? Obviously, I could've immediately focused on writing the app in HTML5, but I did want to leverage all the goodies that come with iOS/Cocoa.
(3) Alternatively, I could write a native Mac OS app. That facilitates the re-use of Core Data, etc., but I heard it takes a lot of work to port iOS apps to Mac OS. The question then is what's more work - exposing the functionality as web services or porting it to Mac OS... in both cases, I would need to rewrite the UI.
thanks everyone,
Fabian
If you want iPhone/iPad users to be able to access the App through the PC web browser to send data/files to the App then take a look # this one:

I did some more research and came across the WebAppKit framework. It allows you to easily set up a web server capability and handle requests and responses. It's lightweight, easy to understand - exactly what I wanted.
I'm thinking of developing a Windows Phone 7 application using PhoneGap and have a few questions around functionality available. I haven't developed a WP7 application before nor used PhoneGap so forgive me if some of the answers to these questions are obvious.
Does PhoneGap support the capability to update HTML/JS/CSS/Images hosted by the WP7 app? I imagine it's possible to easily download new content, but whether one can update or extend the existing files PhoneGap is using for the application is not clear. Given that the application functionality will be primarily driven by HTML/JS, I assume it's possible to download updated HTML/JS asynchronously and update the content on the device. In effect, this would be tantamount to updating the application without downloading a new version of the application through the MarketPlace. Assuming this is possible, what are the chances that an application which does this will pass the application verification process?
Are there any specific restrictions/guidelines that one should pay more attention to when developing an application using PhoneGap? I doubt there are but it would be helpful if anyone has any specific advice in this area.
Any help would be appreciated.
1) The short answer is yes.
The long answer is that you will need to do some native (in this case C#) dev to make that happen. I don't know the specifics of PhoneGap, but I know you can call C# methods from the JS. So you would call a method to download the data and store it in the IsolatedStorage, and then maybe have a callback to the JS to let it know it's done. Otherwise, there may be a way to download the image in JS and pass it to the code behind, but unless the PhoneGap guys have specifically catered for this scenario then I highly highly doubt it.
1.2) Yes, this will pass cert just fine. It is not up to MS to determine how/why/when/where you get your content. They don't make any money out of you updating an app, so they won't care whether you work out your own content delivery system.
2) Maybe not exactly the answer you are looking for - but if you make an app in PhoneGap, or any other non-native way, the app-gods will strike you down. To put it simpler, PhoneGap and everything like it is crap. Not the actual framework (I'm sure they put a lot of work into it), but the results. Seriously, the moment you run a non-native app you can tell how terrible it is. I don't know how to stress this enough. It's really worth developing it natively to every platform.
I have some knowledge of basic PHP developing however right now I am thinking about developing a phone app. I do however have a bit of a conundrum in that I love WP7 and I have so many ideas for features which can't be done on iOS and Android, however at the same time I am completely aware that my target users (filmmakers) generally have iOS or android phones.
Is there a way I can develop the app, which I will get a developer to do rather than myself, with WP7 as the lead platform and then make a relatively simple conversion to the other platforms or do apps generally have to be completely reworked for each platform?
Also, just to though it out there, any idea of where to go to find a freelance app developer?
Thanks
James
I think you have a few options, but the first question I would have is: where comes the data from. Are you the owner of the data, and do you already have a datasource from where you can get the data from? If not I would suggest take some time to write a decent 'backend' from which the different platforms easily can get the data from.
Also all different platforms have their own pro/cons which you cannot share that easily. If you build a WP7 app in silverlight/xna, you cannot directly port it to a ios/android variant, also functionality will probably look/react different. You will need different solutions foreach platform with this approach.
Another option would be to use an platform like phonegap which can create a solution that will work on multiple platforms. (It uses HTML5 to get it work on the different platforms)
Build your app on iOS and android first, and when you have an app to base WP7 development then contact a developer that has made similar apps to yours.
