Hi friends i want to know about how to make apps for different OS.For eg: ANDROID,BLACKBERRY,iPhone,Windows Phone and Nokia phone.Which programming language is required for there different OS.Can any same programming language can be use for all this different OS.
To make apps (mobile apps, I think you mean) for different OS's(I think you mean the different OS's on each phone),(assumption: that you're coding it from scratch) you learn a programming language first, then proceed to learn how to make apps for a particular OS. Typically, you purchase a book (look online for good recommendations) and start from there. You can also find tons of online resource about coding basics, and mobile app development.
I am sure you can use most popular languages; Java, Python, C++/C#/C, etc...
Generally, people make either Android Apps, or iOS apps. They code in Java for Android (and it's derivatives), and Objective-C in iOS but Swift is quite new and I heard it has many cool features, and is the better choice to use for iOS in comparison to Objective-C.
Yes, you can use the same language across the platforms you listed in your question, but generally stick with the common languages most people use, as the difficulty increases when you choose more elegant languages, like Prolog or Haskell etc. :)
#SiddhantSingh you should go for java scripting(i.e.,phone gap)
Android and iOS are completely different. You are asking how to begin creating apps for all phones, iOS is specifically referring to apple products. For apple, go to their website and download the development kit, Xcode (It is in objective-c and/or their own language called Swift). For android, it is primarily in java, and some starter development kits are offered for android as well! To make it really simple these are usually used to develop- Xcode for iOS, you can get it from apple; and some of the most common for Android are gradle and app inventor, which you can get from gradle.com or MIT's website respectively.
If you have a good idea which is support to receive good reviews from all platform App users. I suggest you consider about Web App and Hybrid Framework Development. I hope you get a little knowledge about those two things.
The common point between Web App and Hybrid Framework is saving your time, which means a couple of mobile OS can run your App with one-time development. Multi-OS development and different Program languages are absolutely unnecessary for you. I think this new way of development can bring you the concentration on App's essential thing.

I'm trying to create an app for Andriod and IOS, but i have no clue how to do the front-end and have a hard time deciding to use HTML5, CSS & JS or Objective objective C/Java.
I'ts going to be use network options, checkout-features, joined checkout-features. Maps api, facebook api.
I've got expierence in HTML5, CSS3, SASS, PHP and JS.
I've tried looking online, but i've still got no clue how to do the front-end for app.
To answer your question, you will use framework like phonegrap, Titanium Appcelarator and I guess you can use NativeScript, Ionic, Framework7 as well. For Titanium, you have to use different environment for different app (OSX for iOS products and OsX, Windows or Linux distros to run android app) and have it's own syntax and everything. Language is one of Javascript versions (I am guessing, I have used it once 2 years ago). And Phonegap and other Frameworks use a varient of JS, so basically you will have to use HTML and CSS to work with UI. However, you will face some hardware constraint like unable to access hardware buttons (from my experience with one project some months ago) and memory management and other functionalities will mostly depend on your JS coding skill.
[My opinion] I believe, the best way to develop an app is to develop in its native language/framework. I believe it. Unless you're bound to use Html, JS to build app (you can!), don't use those. Java is there to help you with Android Development, since I am an developer, I can tell you that starting might seem a bit difficult than iOS development. But in the end, communities like stackOverFlow and thousands of thousands blogs will help you. Same case for iOS app development. You can find lots of different tutorials. New Bostons tutorial helped with android however, it's contents are bit old (android 2.3) and mostly everything has changed since. However, you can check his iOS app development with Swift. Learning a new language is mostly like learning how to ride bicycle. If you can know how to ride, keep learning the advance parts after basic mechanics, you can become a pro one day. However, for that you have to pass a whole cartoon of hurdles (unknown bugs, sleepless nights to name a few) like the falls you did when learning how to ride.
I would really suggest you to focus on building a real stack.
Happy coding!
For android:
I would recommend using Android Studio.
It is a powerful tool for creating an android app - the front end can be implemented by dragging and dropping items or by using xml.
It is easy to use and there a lot of tutorials online.
I'm an iOS developer on the native side. If you want to do native development, I would recommend Stanford course CS193P by Paul Hegarty. You can find this course on iTunes U, Coursera and other MOOC platforms. For advanced features, follow a GitHub repo called "awesome-ios" where you'll learn some production level stuff for iOS apps. If you want to do hybrid apps, have a look at PhoneGap, Ionic, React.
In either case, you would be able to implement features you've described in your question.
Tools needed for Native Development: a machine which runs macOS and Xcode(free download from app store).
I started developing native apps years ago. The last 2 years I've been using only hybrid possibilities. Designing and developing an app in HTML / CSS / JS is much easier and more efficiently.
I recommend taking a look at Phonegap, Ionic, Framework7. These are open source and there are already some templates.

I can say it's a long time I've been searching for the more correct way of using my C++ skills for making real world apps. To me, most of the real world apps are graphical ones — those that have graphical environment and GUIs, like any ordinary app used on MS Windows. Of course there are many other (and probably vital) real world apps that are used for embedded systems that may don't have GUI.
Apart from MS Windows, there are quite a bit programs for other OSes like Linux.
On smartphones we also use iOS apps for devices made by Apple and Android ones as well.
My purpose is being able to create apps for the following platforms, in order of priority:
1- MS Windows platform
2- iOS and Android platform
3- Maybe in future, Linux platform or embedded systems
These are my needs generally.
Saying these matters, one idea comes into view: A good IDE that we can use our C++ experience in it to make cross-platform apps that can also supports those 3 needs perfectly, yes, Qt.
But there seem to be some difficulties on using Qt. I read some of discussions said in the link below, but since I'm not familiar with it yet, I couldn't understand high-level subjects.
https://softwareengineering.stackexchange.com/questions/88685/why-arent-more-desktop-apps-written-with-qt
I know that each choice may have its own advantages and weaknesses. But finally I have to choose.
My intention is to start learning Qt in near future and now to be sure that my chosen way for that near future (one or two months later) is not wrong!
Now I want you expert guys that please help this novice to make a correct decision.
My question on making the issue clear for me is that:
Is Qt the best choice for my needs please? (Those three needs)
Thanks in advance.
You can use Qt Qml from Qt5
Qml allows to develop desktop and mobile applications. What you will need is to compile your application for new platform.
Qml is language for developing UI, but qml is javascript-based language and you can do logic in qml files. To provide your C++ classes you can just register they in C++ code.
P.S Qt for mobile platforms is good idea for fast-developed solutions for all mobile platform. If you want to get all available features and functionality from AndroidSDK, for example, you must use AndroidSDK or AndroidSDK wrappers.
P.S.S Qt is the best solution for crossplatform gui applications, and qt is easy to learn framework

I've just started diving into the Android world. I have a lot of experience programming apps in Python, so I've searching for a good combination "Android + Python", and I think I've found it: Kivy.
I need to make applications that are able to download and upload content from the internet, maybe some connection with the map component included in Android and more stuff to make a nice Android app.
But I really don't want to waste my time on something that maybe won't work. So, does anyone has some experience developing Android apps using Kivy? Is it really useful, simple, possible? Or is there a better option you have in mind?
I've been using and contributing to kivy for some time, and using it for a big application intended for market. Although still not as complete as native developpment (not sure if using the map Android API is possible at all, but there are alternatives), it works very well, with good performance. The kv language for rapid prototyping is really cool.
And as bonus points, your apps work on windows/linux/mac/ios too… (we still have to try getting on apple store, but technically it works). edit: to this day at least one kivy app has been accepted on apple market, look for "deflectouch" if you are interrested.
As opposed to SL4A, you get a real apk to distribute, with kivy as well as a very nice and slick GUI api, fitted for multitouch apps.
I believe KivyMaps is pretty similar to what you are trying to do.
If you avoid non-Android platform specific code then your application, should run on Android without any problems.
I suggest looking at Python for Android also, it's a sister project of Kivy aiming to help you create your own Python distribution including the modules you want, and create an apk including python, libs, and your application. Specifically look at its native API wrappers for Android. The project is new so only a few native API's are supported but it might give you an idea on as to how to go about creating a wrapper for Android location service API's if you need that.
As for the Google maps external library, I agree with tshirtman. I'm not sure how it could be used but as the KiviMaps link above highlights there are alternative approaches available.
I have very little experience with it. But I do know that
SL4A (Scripting Layer For Android) does support writing Android applications with Python as well. Might be worth looking into that a bit before you make your decision of what to use.
Kivy is Cross-platform Python Framework for NUI Development.
It is Good for some prototyping android app. You can use Kivy Launcher for more fast test.
You can use python library so fast development for feature.
You can use pyjnius for accessing java classes for java based feature.
I suggest you to reading Kivy Interactive Applications in Python book for newbie.
But in some deeper depth, you should know how to use basic widget carefully.
Because some confusing concept is there. For canvas, it's different concept in html5. Kivy language's class rule and class is some confusing for newbie.
And for android app, there is some difficult to use not basic supported library like Beautiful Soup(famous html and xml parser library).

I am new to Java and I want to create a Java app for mobiles. When I approached software companies they asked for "Android / Blackberry / Symbian" etc...
Being a newb, I am really surprised by these questions. Can you please tell me whether there are any other mobile platforms in Java?
Are Blackberry apps and Java mobile apps different? And what is the target phone for j2ME applications?
Java ME is waning.
iPhone is Objective-C; there's no Java on iPhone.
Android is its own platform, different from Java ME.
BlackBerry used to be based on Java ME, but they're moving in an HTML/CSS/JavaScript direction, away from Java ME.
j2me is a technology that was used a couple of years ago for creating those apps on the cheap phones (think pre-smartphones). blackberry and symbian have a bit of an extended java libraries but it is still similar to j2me (painful to create apps that don't look good plus in later global events symbian os is becoming more and more unpopular which means less and less developers are needed).
But basically the major part of the mobile apps are written in java, one way of another. there is also IOS which uses xCode. maybe even some embedded development platforms that are using c++ or something but i can't really say for those.
EDIT:
Oh and yes there is windows mobile now that is becoming quite popular. getting into windows 7 mobile development is actually a good idea in my opinion. Although currently its pretty poor in terms of available resources community etc.. it can possibly grow in the next year or two. Plus the app competitions is quite small, there isn't a market so its easier to push through a successful app (which isn't the case with iphone and also the android market becomes filled really fast).
J2ME only supports on Symbian and Blackberry platform. LWUIT is J2ME framework. You can develop symbian, blackberry and android application by using this framework. If you are using LWUIT framework means no need to write the coding for different platform. You can use same coding for all platform(Symbian, Balckberry and Android). But you have change some small changes for each platform.
Basically iPhone supports objective-C. But you can develop the iPhone application by using C# with MonoTouch framework. If you know java means C# with MonoTouch framework better for iPhone development. But it will be cost.
As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.

I have started to build my own apps on iPhone and iPad using the iPhone SDK. The next question that is always asked by the client is, "Can we have it on Android?"
So my question to you, 'the internet', is: what are my options?
I don't have the time to learn another language (learning iOS has been enough!), so are there companies who specialize in this, or are there any online services that do a conversion?
Any help on this welcome, just need to know which way to turn...
No, there is no way to convert an existing iOS app to an Android app.
However, there are cross-platform frameworks that allow you to code once and deploy your app in more than one platform. The most popular are based on HTML/CSS/JavaScript and one of them is PhoneGap.
You can also develop for iOS and Android with Adobe technologies such as Adobe AIR (this was forbidden by Apple until recently).
And there are online services (such as Mobile Roadie) that allow you to generate cross-platform apps using a content management system.
That said, I strongly recommend to:
Learn Android and Java development if you want to specialize in mobile development.
Take advantage of the strengths of each platform when working on an iOS/Android project, instead of creating something that uses only what's common to both.
Converting a native application from one mobile platform to the other is not a straight-forward process unless the initial application was built with a framework with cross-platform capabilities from the start.
Your options at this point are learn the other platform and develop it yourself, or contract with another development company which specializes in the platform you need to target.
Due to the massive differences between the 2 platforms, you are looking at a complete rewrite of your application. You either do it yourself or pay someone else to do it. I don't see any shortcuts you can take.
You may be interested in reading my book, HTML5 for iOS and Android, which enables you to take web apps created in HTML, JavaScript & CSS, and turn them into standalone apps that you can upload to the app stores (for free or to sell). See http://html5formobile.com - the wrappers to do this for the iOS and Android SDKs are freely available on the website, and you don't need any knowledge of either programming language if you follow the instructions in the book.
You can try the following https://bitbucket.org/zabirauf/icona.
Its open source iOS to Android Application Conversion Tool.
Even if there was a way to easily port an Objective-C application to Java, I wouldn't highly encourage it. iPhone users and Android users are two different families of users. The typical iPhone interface just wouldn't sit well with Android users who aren't familiar with how the iPhone works. Yes, I understand that the UIs of both iPhone and Android seem pretty trivial to learn to most people, but when you break a novice's comfort zone, it puts your applications (or websites) on a higher learning curve.
You should take the time to learn Android's language and UI and develop your application in a fashion that is consistent with how applications on Android work. As said in other answers, if your taught yourself Objective-C, you should find that Java will come pretty easily to you. In addition, in never hurts to know more than one programming language.
You can't just convert iOS apps into Android. iOS is Objective-C and Android is Java.
I highly doubt there are 'converters' on the internet, even if there are that's not the way you should program an app because every SDK has his own special capabilities and you should use them for maximum user-experience.
I'm sure there are some companies who specialize in porting apps from iOS to Android. Look it up on Google I'd say..
If you want an easy place to look for android development you can try appMaker which I hear is a GUI based Android development tool or I believe Google has released its own GUI based android application development tool. If you are not a java programmer than you might be better off with the gui. Otherwise I would say android is not too different from traditional java. As a java programmer who went from Android to iOS, I will tell you Android is a walk in the park compared to learning iOS. Two completely different beasts in my opinion.
Selecting a mobile development environment which will enable you write once and deploy/distribute it on many devices would be a better solution in the future. If your application is HTML-based, go with HTML5/CSS alternative (ex: PhoneGap, ). If you prefer native, then chances are you may want to learn Lua, a scripting language (ex: Gideros Studio) or C++ (ex: Mosync).
Other than that, the application you created on iOS with Objective-C is very, very hard to port to Android and other devices.
