I am new to developing mobile apps. But I have plenty of ideas and coding experience in php, javascript, html5 and other web technologies. Currently I am planning an application which requires to use lots of hardware features which include microphone, camera, usb/otg, wifi/network, proximity sensors etc. AFAIK there are two kinds of app that exist in the market today:
One that do not use hardware sensors at all and only use display methods and network communications to work as applications.
Others make use of one or more hardware sensors.
Now I want to know which rad frameworks are available which could provide best of both worlds an individual comparison for both types will be good. Also if the same framework can co exist on other platforms (maybe iOS or windows) that will be awesome.
I went through multiple app frameworks that can get me to develop apps in no time like jquerymobile, enyo, appium, etc. But I could not find upto what level of hardware sensor api can they provide to the app built over them.
Check out this interesting Mobile Framework Comparison Chart. It compares the OS's, the supported languages and the supported hardware features.
For your specific needs, I think indeed Rhodes or Phonegap are good choices. There are other discussions about which framework is the best, I suggest you read them and make a choice.
You may check out PhoneGap.
This framework uses HTML, CSS and Javascript.
I've never tried it, but it seems to fulfill your needs.
It supports:
Android
Blackberry
iOS
Windows Phone 7/8
Windows 8 and others.
Regarding sensors, it offers APIs for:
accelerometer
camera
capture
compass
geolocation
storage.

When you have to implement system which needs:
Backend, Frontend (Angular for instance), Android, IOS
You are considering implementing a mobile version of frontend and use webview instead of native Android or IOS app?
Of course, it depends on the project, but let assume:
We don't have to use Android / IOS features like notifications, sensors (Bluetooth, nfc, ...)
Our project is a page for instance "StackOverflow", where the user may authorize herself
Nowadays, we are also implementing the mobile version of the frontend as a good habit
Usually, native apps would always be better, but maybe it's faster and enough to use webview instead of implementing two native apps?
There is no correct answer to this. One could use a PWA, a hybrid app (many ways of doing that). As always, it depends. I don't even know if native apps are always better. They are more expensive in many cases, but if that is 'better'? Wouldn't a web app work too? It almost certainly is faster and cheaper to develop one (web-)app for multiple platforms, but what way to go is the best in your case is entirely up to you to decide.

I'm relatively new in mobile development, but I'm really familiar with HTML5. I have a project, wich will be used in pubs, where the customer orders the bar through his cell phone. Some informations:
The bar will have a local server to receive the requests (it will work in local network)
The clients application will have live a chat, so the customers can meet new people in the same bar :). However, the chat server will be online (the customer will need internet to access this functionality)
The application will likely use push notifications and maybe perform some simple background processing.
The application should be Cross Platform.
So what would be the ideal technology to use? Cordova? PhoneGap? Intel XDK? Xamarin? Embarcadero? Should I also use WebSockets?
Thanks!
So phonegap/XDK is really the same a cordova and they're all fantastic. Phonegap and XDK are just... implementations of Cordova. Phone gap can do everything you want it to. I've used phonegap to link multiple phones to a server(and each other) for a grocery deals app.
I would hold off on websockets(though they technically can do what you want). They're not the most maintainable or easiest to set up.
I've explored Xamarin a year ago and it looked like it would work for my(and your) applications. However, it seemed to be completely tied to the .NET framework. So if you don't mind being led by the nose for all you're profits...
I have no direct experience with Embarcadero, but I've now signed up for a trial due to this post.

I don't have much idea about all the technologies you asked but I have worked with cordova and accomplished all the requirements for your app. It can be a good option. I'm not very familiar with other tech

I need to write a client side application which communicates to a WCF service.
The app is actually targeted for multiple platforms.
Internet Browser.
Android.
iOS
Windows Phone.
The client side is rich on UI.. should contain animations and "fireworks"..
In the past, Flash used to be the generic 'Glue' to hold all that.
But These days, I keep seeing and reading about HTML5 hype..
I also heard and read a bit about Xamarin but will not dive into it before I get some confirmation that it can deliver what it promises.
So, My questions are as follows:
What would be the technology to use in order to develop client side?
Html5 or Xamarin - or should I just stick to flash?
do note - this is not a request for opinions - or in other words:
I'm looking for answers of experienced developers who already done something like that and can tell me of a sure path to success.
Xamarin and visual studio - is it correct that this will allow me to develop everything on VS.2012/2013 IDE and will be able to output packages per OS?
Keep in mind I'm MS oriented dev.
Thank you.
You mention candy crush.
The realistic answer in business today is simply develop the iOS, Android, and anything else natively. It's the only thing that really works.
Trying to save a few dollars on 'cross-platform' is useless.
For 2D or 2D games specifically, you should use Unity3D, which is the overwhelming market dominator, currently, for games production.
In general there are any number of better-or-worse "cross-platform" things like xamarin, appcelerator, etc etc.
But the overwhelming factor in your project will be, you need to forget about a server side and change to parse.com. That time-saving will utterly overwhelm any "minor" decisions about what to program the different platforms with.
FYI Unity3D works with c#. Android is Java. iOS is objective-C.

I have a relatively simple tkinter program that just uses Event, Button and Label objects. I would like to translate this to be usable on an android platform.
1) What python for android should I use? QPython, py4a?
2) And on that platform, what GUI module should I use?
I'd like a little bit of detail for why you think a specific module or app would be best, as I'm just getting into the android scene and want to make an intelligent jump.
Even for native purposes, most developers would advise you keep away from Tkinter. It's a dated and unintuitive library that often makes GUI creation and maintenance harder than it needs to be.
The main advantage of developing apps using a Python library and embedding in Android is cross-platform support.
These libraries will often allow you to port your app with ease to many different operating systems.
I will not answer which is "best" since this is an opinion-based question outside the scope of StackOverflow, however I will say it is (generally) easier to port from Kivy to android than it is in some other libraries (such as Qt). But take this with a grain of salt.
Most libraries nowadays offer advanced GUI capabilities built-in, and your choice will likely not limit you in that regard.
Either way, there is no direct/simple way to translate your Tkinter project to any of these, and you will likely have to rewrite it with the library you end up choosing.
I will add that if your intent is developing only for android, most would advise developing in a native Android language, such as Java or Kotlin, or using a development tool which makes use of such languages. This would result in smaller APK sizes and likely faster running times for your app.

I'm an iOS coder and have been asked to write some cross platform code with Phonegap or Titanium. There's plenty of information out there about setting up development environments, etc... except I'm missing one crucial piece of information.
What mobile hardware should I buy? Now that's a pretty lousy stackoverflow question, so let's rephrase it to be useful.
What criteria needs to be examined in choosing an Android tablet for iOS/Android cross platform development with PhoneGap or Titanium?
The corollary question is also useful, what criteria needs to be examined in choosing iOS hardware for cross platform development with PhoneGap or Titanium?
A good general approach is to pick high volume devices with an eye toward diversifying hardware- so for example if samsung has a really high res phone, don't buy another really high res phone from LG or if all the available Android phones are high res, try to sprinkle one in that has a slide out keyboard. Don't worry about trying to test everything on every device, test things that should work the same across a small number of devices and then test the things that could be very different on a larger number of devices. Depending on your app there are probably a few things that you know could behave differently on different devices- focus on this. For example, we test the camera on all devices but we would only test something like an alert message on one device.
If you are looking to build for iOS and Android I would also recommend checking out Brightcove App Cloud - http://appcloud.brightcove.com. There are good testing/debugging tools and plugins are well-documented and fully supported.
