I need to develop an HTML5 mobile business application using PhoneGap. After finishing my application I want to make it a native app.
Can anyone tell me What is the best way to do it
Develop an application using HTML5 and Javascript, call web services from Javascript and embed it in a native app using PhoneGap
Develop an application using HTML5, Javascript and PHP. (server side). use PHP to call web services. use PhoneGap to call server urls.
1st one seems more native and fast. 2nd one seems more flexible and secure, but I need an additional server for that.
so what is the best solution?
Although I agree this is too wide a question, I would go with #1 because certainly in the case of Apple and iOS I am pretty sure you would not be able to get an app past Apple's gatekeepers if it loaded remote code (Javascript, etc).
Calling out to a web service for remote data via AJAX, etc is fine however.

I have a Node.Js app running on a publicly accessible server.
I want to make it possible for users to access it as a native iOS app.
Is there a simple way of simply making an iOS app and having it show my Node.Js app running from the server? Or it's more complicated than that?
I looked into PhoneGap but maybe some other recommendations also?
Thanks!
PS I know the question is broad but that's why I'm asking – to focus my question and to know what to do next.
Node.js - this is a server side application. So you need to build client application which can communicate with your node.js server by Rest api or so...
As you mentioned you can build hybrid html5/js app with PhoneGap, Cordova, Ionic "wrappers/libraries" which will pack it into native iOS/Android/... application and that app can talk to your node.js server and transfer data you need.
Also, as Daniel Larsson mentioned for some specific pages you can use webview to display page straight from the web, but webview can be a part of your application but not an entire application, because Apple will reject it during review process.
If you want to port your existing web-app over to being a native app on the app store, I can positively recommend PhoneGap having developed multiple apps with it after completing the same research you are doing now.
As NYS said, you'll need to package all your web-app design (HTML/CSS+images/JS) inside the PhoneGap app, any other way simply wouldn't be responsive enough.
As for what to do next, I would dive straight into creating a PhoneGap application and see how your app runs inside the Cordova wrapper out of the box. The issues I faced were with scrolling on divs holding content, and non-responsive click events, both were easily solved with javascript libraries.
Cheers Chris!
You may use Socket.io for native option.

I'm developing a web app using HTML5,CSS3 and JavaScript.
Then I want to use the Apache ordova platform to generate a native android app from my web app but I still don't understand what do I need for this,specially do I need a server-side development with php for example??
First off i suggest you read this
Pretty much your app will be able to accomplish a little bit more than what you would be able to do in a browser if all you had available was the ability to write html/js*.
*by this i mean that you have access to device-specific hardware which is not available in a browser and a few more things but pretty much that's it.
You will need to install node.js (or io.js), then install cordova through npm, and make sure you have the Android SDK installed. Once you create your project, your html/css/js will be wrapped into a native webview component, you do not need any server to render it, effectively your app is a native app that can be installed from google play.
You will need a server, typically a RESTful API, if your app needs to query data remotely or persist to some third party. If you are thinking through a classic MVC mindset (render a page through some php code) then you probably need to read about cordova and how it works. A cordova app is a client-side only app, no server-side processing is possible unless through a network communication to a server you have access to on the internet. You can do persistence locally (to the android device) and even use a local database, but remember that this db exists on the device, so you won't be able to share information between users unless you somehow coordinate that through your app (and most likely a server-side app / rest api).
It is unlikely that your existing web app can be wrapped into a cordova app straight away, cordova apps are single page apps mostly.
I want to be able to create an offline program that can use the browser as GUI. I'm not particularly good at GUI programming in general, and overall it seems that using HTML and CSS to structure a GUI would be the easiest.
Cross browser method is preferred, but I will most likely use Google Chrome
I need to be able to open an external program, possibly with command line arguments
Javascript seems like the best language for this, however as far as I know it isn't possible to launch programs with it.
This is on Windows 7.
That's a good idea and is done by a several popular softwares.
The best way is to make your offline program run a web server that the browser will be able to access.
ie: Your program starts a web server on localhost:5555 and then you'll be able to request http://localhost:5555/users in Javascript, from your browser.
Another approach could be using a UI framework like AngularJS + local storage. I'm working on an app right now that will be used online (connected to the web), online locally (connected to a local server that is not connected to the web), and offline.
You could build a single-page web app and let Angular manage all the "urls".
I have created simple chat application which is fully based on html, JavaScript and JQuery on the UI side and Spring REST in back-end (DB). here i'm using phone gap to convert my web app into native Android application. lets assume the scenario that, there are the two users in one conversation, the first user sending message to the second user. here i want to update the second user screen using atmosphere asynchronous communication.
but the Android WebView isn't supporting websockets to perform asynchronous communication between the server and the client. how can use atmosphere plugin on the android WebView.
is there any possible ways to do it? please share your answers if you know.
Thanks.
I am wanting to develop an application for mobile devices, which shows in real time where a user (with this software installed on your mobile device) is. The idea would be that one (or more) users could follow the map the displacement of another user via GPS. I want to use PhoneGap with HTML5 and CSS and Javascript.
My question is: Is it possible to do that with these technologies? If yes, where can I get information of how to handle the GPS that way? If you can not, which language would give me this possibility and where can I get information? At first, I intend to develop this Application for Android and IOS.
Yes it’s very much possible with PhoneGap technology. You have to write a web service to keep the GPS coordinates as user updates (or auto updates) in server. You can let other users to connect to Web service and get the info they wanted (i.e. the data they wanted to see the current location of the user). You developed using PhoneGap means, it’ll work for iPhone too.
You can easily develop a web service either using PHP, Java or C# though C# web services are easy to write and maintain but PHP web servers are cheap compare to windows hosting (which you will need to host C# web service).
The question you asked is very broad so can write a 1000 words article and beyond. If you ask specific question I can answer that.
