Hi all,
we're looking for an Android app developer, to create at least two apps. One is pretty simple, the other a bit more complicated. Both apps are already created for iPhone, so basically we need them to be available for Android.
All the details will be provided by email.
Contact me if you have time and experience, and affordable pricing
Cheers,
R.
I dont know about iphone development, but you can organize develop entirely in java to gain platform independent solution
android does not run the standard java byte code.
If you think you can go multiplatform by writing once, the answer is no.

Hello there, I've already posted this into another forum but I've been told that this is the place to put this question so here we go
Okay, so I'm starting to develop apps for my XDA2 and having come from a standard PC development background I was always told that software should uphold the basic principles of software quality IE reliability, reusability, maintenance and so on
I thought it would be an idea to here from people that develop for the mobile platform weather they feel it is possible to develop apps with these software engineering fundamentals.
Do we have to abandon object orientated programming, and go back to the procedures in order to develop?
Sorry if this is a, a silly debate, or b, been talked about before
lets have ya
And here is an excert from a reply from on off the board members
Rudegar:
Some people use gcc some people use win stk
where you have to make oo from the buttom if you want being that both are c++ it's by far impossible
and some program mfc and .net where oo is very much a part of the way things are don of cause using these tech's you can still program without following the guidelines of oo

Why would you abandon OOP?
In my opinion, OO makes the development of any application easier, not to mention the inevitable maintenance/bug fixing/etc. It allows for reusable code, which is a good thing.
I believe one should develop applications in a way independent of the target platform. The main difference is the GUI design, but I believe the GUI is not to be designed by the person who wrote the code.
I.e., the programmer designs and develops the code and functionality, and someone with good understanding of (G)UI/man-machine-interfacing should design the UI (which the programmer subsequently translates into the application)
I want to focus on developing GUIs but I'm not sure where to start. I just read through a few pages of http://source.android.com/ to get more information and it was helpful but I'm still not sure what my skill set should be. I also went through Google's new App inventor and finished all the tutorials but it still seems like a toy.
I can: design interfaces, code javascript, implement XML (weak on C and Java but I get it), create anything using photoshop or any graphic application, color-coordinate, test and implement and write--I can write technical instructions fairly well.
So... that said, what's a typical Android designer's skill-set?
Thanks.
Patience, mellowness and a strong constitution!
The Android development platforms so far available are pretty poor if you're used to something like Visual Studio. The best option seems to be Eclipse running the Android ADT plugin. There is plenty of documentation about how to get it all up and running and it is quite easy to install and configure. The app inventor is a toy for non-developers to create simple applications and it works well for what it is but as soon as you want more complex UIs or more complex code, especially when it comes to using external libraries, you will need to get into Eclipse.
You have the right skills, in fact I would say UI and graphics design is the weakest area for many developers. It is for me. I can write beautiful functional code that does amazing things but my UIs suck unless they are simple. I always need to find someone who can help me with that. In my experience, and I have a lot of commercial code development experience, good UI design is a widely missing skill. It therefore pays well and is highly sought after. You might consider specialising in it?
Be careful going from C to Java. Java is still a pig of a language, do a little googling for "problems with Java" and be especially careful of the fact that Java passes everything by reference unless you use cloning. If you don't always write very loosely coupled methods and are good with encapsulation, this will bite you and often in very difficult to understand ways. I recommend running through each method with only this in mind before you consider the first version of the method complete.
My advice to you is to get Visual Studio Express (they're free), either VB or C#, it really doesn't matter, and become proficient with object oriented programming, proper error handling and scope of objects and variables. Do these things, and assuming that you have the right mindset to create good code, and you'll protect yourself from all the usual bugs that amateur developers introduce.
Then move back to Java. Java is a lot easier to be proficient in when moving from something like VB or C# because whilst frustrating, due to the things you'll miss, you will at least know rather than "not know what you don't know", if that makes sense.
If you are serious about doing this for a living, buy some books by Steve MacGuire.
"Writing Solid Code"
"Debugging the development process"
If every develope could do what these books teach, we would have a much more capable software world.
Good luck!
I have the same question? What do you think will be future programming? Developing web apps like Facebook or Android apps?
How is with work today?
I did banchelors from computer science, and want to try masters now, but I need to choose developing Androids apps or Webapps. I am pretty good at C#, JavaScript, XML.
There's a lot of milage in mobile apps, will be good for many years but there is no doubt that the future is web apps.
Excellent! What a great response. Source.android has a lot of information on what a developer should know but I still can't find information on Android GUI design--specifically. Any advice on this?
Thanks.
I think everyone should learn some c/c++ or other native language. Most will say im crazy for saying this but to appreciate what comes with the languages u mentioned above(which are all managed code) I think you should learn power and use behind native code.
c#, java, .net are all good places to start, i would not go with vb. If you choose to start with c/c++ you will be able to do any of the above easily. Tho others think its harder to learn...I say others bc i have always preferred c/c++ to the above.
Simonta... You rock!
Many Thanks.
Hey Devs,
After years of being into mobiles I want to start developing my own Apps.
I want to specifically program Apps for Android because I really like how Android is set up. the way it handles "closed application" and ofcoursebecause more and more people are getting an Android.
Now I'm not sure what the best way to start is.
How did you guys start developing for android?
Which books did you used?
I hear a lot of people telling me I have to start with Java, now I get Java at school but how much Java is enough to start in android? do I have to go as far as BufferedReaders and Swing or just the basics of Java?
I found this book: http://www.pragprog.com/titles/eband3/hello-android
That seems really interesting because it covers Android 2.1, does anyone have any experience with this book?
Or any other book?
All help is welcome!
I really want to make a good start in the world of Android programming
and what to get it at such a level I can actually develop programs in a company.
Thanks in Advance,
//Sterallure
Can nobody help me out with this?
As long as you know most of the fundametals of java programming learning android api and libraries should'nt be all that hard. I'd start by going to the developer.android.com learn how to install the android SDK and Eclipese, also read through the dev guide. Hello, Android latest Edition is a pretty good book for beginners, beginning android 2. as you get better move to pro android 2, or what ever you think will fit your needs. There is enough information online such as developer.android.com, forums, and tutorials that can help you learn android without having to buy a book.
I have to agree. I am no crack programmer, but there have been tutorials or sample code around the internet for almost everything I wanted to do. Especially forums and blogs. Google is my friend.
Thanks alot for the information I will also look into Beginning Android 2. I've read a couple of dev guides but I always really like reading books.
I just want a really good basic knowledge of Android programming itself and I think the API will come later, if I just know how to program somenthing then the API is helpful for creating new things
Programming for Android is basically using the Android API's
I suggest www.commonsware.com books. Its a $40 subscription and you get 4 books(Android Programming, Advanced Android Programming, Android Programming Tutorials, and Android Beyond Java) that are updated periodically. Its really a great deal. I have it and I've learned so much and also the author is very active on stackoverflow and also writes many articles on android.
Has anyone used Xamarin to build their android apps? I have been programming using C# for sometime now but have never used it to build anything for android.
They have tons of free libraries, but as for licensing, I am skeptical in purchasing. Anyone like or dislike Xamarin? If you do or do not, can you explain why? Thanks a bundle!
Haven't used it but you have to think whether it's worth the price. The advantage is you can write in C# and share code between Android/iOS. However the UI is still platform-specific, so it has to be implemented twice. A free alternative is to use C++ for shared code (Android: via NDK, iOS: compiles directly), but that definitely needs more initial setup effort than buying Xamarin's product.
Here is an informed opinion
There is a gaming studio that used Xamarin to port their WP stuff to Android and iOS, and they're quite happy with how it turned out.
Do a search for "FourBros Studios, Cross-Platform Game Development with Xamarin and MonoGame". I can't post a direct link because of forum rules here.
Of course games are entirely different beasts than regular apps (for example, UI-wise), so not everything may apply to your situation.
I've plaid with Xamarin... and its a good system.. but Is it worth $300 to not learn java?
Cross platform development tools have their place, but IMHO unless you have a large project and NEED a cross platform development tool you are hurting yourself by not going native.
Just my .000002c
Java is so similar to C# I would think you'd be fine just going native - in terms of syntax they're virtually identical. I do kind of miss the var keyword though lol
I agree with LostByte - there's no real point to going cross platform unless you really need it. Don't stay with C# just because it's what you know! Use what's most appropriate for the app
Hi,
New here and generally new to the mobile application development scene. I just begun my thesis for my last year and one of its components is to develop a mobile version of the "program" that we're working on. Since I have no idea where to start and what platform/tools/method to use I'm asking here for advice. The teacher gave me some papers to study on and I must say I'm quite confused.
First let me give you a fast explanation of what I'm trying to achieve. What I'm making is an application for online voting on the decisions the student council takes. What this means is that instead of having to meet up every other week the members of the council will be able to post their ideas and proposals online, people will be able to ask questions and then they will be able to vote for whomever they want. This will be accessible from both a PC and a mobile device. One of the most important factors here is the security of the application/program since it is paramount that no votes are lost, counterfeited, deleted, changed or w/e. After that we're also gonna need database support since everyone will have their personal account and other than that it's gonna be somewhat like a small forum.
So the idea at first was to develop this in applet form (not sure if my terminology is correct on some stuff please correct me if i'm wrong) and embed it into a web site, accessible by everyone. However the professor that's overviewing the project also asked to make it so that people can use this from their mobile devices, so here we are. I've read on the different implementation methods (like native and web based) etc. and I also read up on cross platform development tools like phonegap and titanium and that's where the confusion starts.
First of all we want this to be accessible by almost everyone regardless if they're using iOS, Android, Symbian etc. If that's impossible at least iOS and Android is mandatory. Starting from there, native development tools are probably a no go since they require different versions of the program for each OS and possible device type. On the other hand the cross platform approach apparently doesn't offer good security (not exactly sure where that weakness comes from) and that is something we're trying to avoid. However I'm not sure if I've understood this correctly and I might be misinterpreting. Anyway, concluding it seemed to me that developing this as a web-application seems to be the best decision. If I go that route what exactly am I looking to do? Where do I start? Do i just make stuff in java and make a webpage via HTML 5 and add stuff in? I'll look online for tutorials on this but I'm not exactly sure where to start so I'm asking here.
Thanks in advance!
Unless there's a specific reason for wanting mobile apps then I'd recommend doing this as a website, making it responsive so that it's mobile friendly. That way it will play with all the mobile platforms, and all PC based OSs, with just 1 code base. Then the only choice you have to make is the server side code, which is what would handle all the database access and security etc.. The most obvious choices for that are PHP or C#/VB.Net. Both the platform and your own preference are what should make that decision.
Either way, whether you make a mobile app or a responsive website, you'll still need a server to do the data access and security for you. There's tons of good resources and I couldn't recommend Stack Overflow any higher than I do. Just make sure, if you ask any questions on there, that you know how to ask a good question, or you'll get downvoted and the question closed!
I hope this helps - good luck
If you want security in your mobile app as the most prominent feature, you'd have to rely on Native codes(Java/Objective-C). Cross-platform tools are no good when security does matters. Also it normally takes much less time to create some app in Native code than to create it in cross-platform tools, since most of the UI are at your disposal. Acc. to my personal experience cross-platform thing is good if you already have a previous source code available and are trying to port it on mobile.(Such as having a HTML website and trying to port it on phonegap will make sense)
That's just my opinion, other people may disagree with this.
Making a mobile friendly website is another choice as explained in previous post.

Might elaborating a bit on why use C#? Is it better when it comes to coding server side stuff? We were discussing what language to use with my professor and since he teaches OOP via Java he favors it a lot. However if it has drawbacks compared to the .NET stuff I'd like to know so that I can discuss it with him.
Also this project is part of a thesis and I'm pretty sure the professor wants to add the mobile application part just for the research and development process. It seemed to me that it was redundant too but I'm gonna guess he won't take no as an answer... Gonna have to discuss it more
Thanks for the replies so far!

I did think it may be a case of him wanting you to do some mobile work, as well as web work. It does make sense if it's meant to be for the purpose of learning and experience.
I mentioned C# purely as an example of a server-side language, like PHP. You should really look at using whatever you're most comfortable and/or familiar with. I do use C# on a daily basis as a server-side language and it's very simple to write methods that take post data and return whatever is required (usually a JSON response), whether it be a web service with exposed public functions, or a generic handler. There's tons and tons of ways of doing it so you need to really decide what suits you and the environment you'll be working in.
I'm not familiar with using Java as a server language so I can't comment on that.
