Hi u was wondering, how much java coding experience would an average person need, in order to make an android app? For example., 1years experience?
Sent from my XT910 using xda premium
I'm afraid that's not a question that is possible to answer in a general case. It would really depend on what that one year's experience contains.
Having said that, I think it would make it much easier for someone to get started having that experience with the Java language already.
So ya I was reading that java is number 1 and xml basics is also important, but I was wondering how much schooling time is needed to sorta be successful at making an android app. Also is there any other knowledge I will need to know besides java and xml basics.
Sent from my XT910 using xda premium
There are far too many variables to answer this.
Previous coding experience (non related language)
Previous experience with Java/C#/Similar language(s)
Complexity of the application
How optimized you wish your code to be
I have done it learning by doing. I had NO experience with Java when I started programming Android apps (ok. Some knowledge of Delphi). And I managed to learn it.
Just learn everything by doing. :good:
Ok so I have an opportunity to get schooling in coding and then after take a test and get certified "I believe" what should I study? Java?

Yes, Android apps are programmed in Java.
Anything else?

Do that first. You will learn the Android xml syntax by doing.
Just one thing to learn: Where the Thanks button is.

the schooling will probably throw a textbook in front of you and have you learn by doing it. The advantage of the schooling hopefully would be having a teacher to help find errors in your code. With that said the online community is pretty good at doing this.
I took a class on C++ when I was in 10th grade and hadn't programmed (aside from some TI-83 plus programs to help on Math exams) since then until this year when I graduated College. Most languages are similar and if you understand the underlying logic it wont matter which language you learn you will pick whichever one you happen to work with quickly.
Every school experience is different and if you may learn a lot from it or you may have to teach yourself a lot afterwards.
Just start doing it, you'll learn it on the way. For example, study "TheNewBoston" series.
Unless you want to make it your living because if you are an autodidact, like me, it is likely your code doesn't meet commercial standards...

If you haven't done anything with Java before follow a tutorial then try build from it with other codes that you can fine on the internet, helped me a lot
so guys i am fairly new to this have a few ideas popping in my head and i would like to do some app development but i need a push into the right direction such as a great starter book that would help me understand the coding and app building for "dummies" or something that would get me on the right track anyone who has some great ideas please let me know asap before i buy something i regret, the input of new android developers would probably be the most helpful cause i would like to know what they used to get them going in the right direction.
Study Java first, I suggest head first Java. it's really a good book for beginners, I just bought it at Amazon and it's on sale.

i do realize there is a lot of work involved but this has always been a dream of mine at least since i have started android, doing rooting flashing roms etc... i figured i would jump on the band wagon and do some developing myself i realize that is some time consuming steps involved but i think it will be worth it in the end, if i find a great idea that someone likes and build on that hell i could make myself rich so to speak anyway thanks guys more ideas would be very helpful i am guessing that c++ is the language itself i need a bit more input before i jump the gun and buy something that i don't need yet more or less like buying a chager for i phone that i don't have yet thanks for the input.

Why recommend c++ when android apps are written in Java? If he is going to be learning from scratch anyways there is less than no reason to learn c++
Learning c++ would not help you with learning java unless you already knew c++ and since you don't just learn java.
There are some great intros to object oriented programming that use java as a base. Don't have any links at the moment. Just dont learn c++ if you want to do Android dev
From something awesome
thanks guys i decided that i am going to read up on some java, and the book i was looking as has two editions the first one made in 2005 which is way old and probably outdated and the second one i am not sure when it was made however it looked way fun to read btw i hate reading but i would do it to learn something else. i was looking at head first java but there is two editions which one should i get i see better review on 2nd edition than i do on the firlst however if i skip the first am i going to skip some knowledge that i would have been nice to know on my near road for success.
As I've already said earlier that there's not such a hard and fast rule that you have to learn c++ before Java but the better way is to go step by step, have a strong base, it'll help you in firm footing in your job. Then you'll be able to work on different platforms unless you will limit yourself and waste the talent and aptitude you have. I've also told you to go to an experienced person for better advice, if you really wanna do something.....

Since nobody else directly answered this question...
When a book comes out in a second, third, fourth ... hundred and ninety-six thousand and forty-third... edition, they're all pretty much the same book -- usually. The differences in editions are usually just updated information.
Especially when dealing with programming, new user interfaces will come out, or updates to the underlying core will be made, or whatever. Point is, the subject matter of the book changes, and the book is then revised to match. Since rewriting the whole book would be very time consuming (not to mention unnecessary) they just update pertinent parts. Usually, the book is 90% to 95% unchanged. However, don't expect an older book (say, e.g., from 2005) to have information related to the latest version of the software it covers.
If you're intelligent enough, you can probably read the older book to get the understanding, and then figure out the updates on your own if the later edition is too expensive or not available in your area or whatever (after all, you won't buy the revised edition of the book every time the software is updated), but it's best to start with the latest edition if you can.
Good luck on programming, especially if you've never done it. I wanted to get into it, and was even taking classes in college, but my junior year saw price and scheduling changes I couldn't handle with my then-new job. Very time-consuming. I understood the concepts -- we started with C and then C++ in junior college and at university we got into COBOL (why?) and Java, but between work and a fiancée that needed attention, when I was home I just didn't have time enough to devote to it to meet deadlines. However, were I single and only part-time employed, I probably could have handled it.
Completely agree with cj.... ;-) he is 100% right...

im sorry but this is crazy... while c++ may be a step, its on the wrong set of stairs! the base is just programming paradigms that are language agnostic. and if you want to teach those why not start at C? why skip that part of the 'base'? of course if you want to learn Java and dont know those basic programming paradigms you CAN learn them in Java (as you can in C++). a single Class program with a main() acts nearly identical to a single file C program. so the only reason to study other languages would be to learn their intricacies and the way they handle inheritance, abstraction, threads, etc... and if thats the goal then why start on a language other than the one you want to learn? if i wanted to learn how to make and use a MySQL database would you recommend me starting on another completely different data base structure?

thank you

also i dont think this is the OPs 'job' he is just trying to learn some Android programming....
C++ teaches coding principles that apply to most languages, and the detail needed.. Skipping may take time out of the process, but to be an effective and effecient coder, you need the skills taught by learning C/C++..
Skipping the basis for most modern programming is just half-assing it, and will most surely lead to this guy not becoming "rich".
And really, what sense does it make to argue, if he is searching for information, it is all different means to the same end. What's it going to hurt to learn a language that will definitely benefit him.
You just want to be right and seem to be the "expert".

thats wrong. they arent skills taught by c or c++ and c/c++ arent needed to learn them. they are universal paradigms that can be applied to any language.
logic is language agnostic.
and what would hurt him learning C++ when he wants Java is being trapped into the ways C++ does things that Java does another way.
---
i dont want to be an 'expert' im just trying to prevent this person from going down the path of learning C++ which can be used in sooo many different ways when he wants to learn Java which does things its own ways. its like if i asked what i should do to learn Android programming and someone said that i should learn to code for iOS first. durh
and yes this really bothers me. i have nothing against C++, its a powerful language for the things that use it. but to suggest it to a person interested in Android dev is shilling for a programming language that has nothing to do with what wants to be done.
Bro, don't waste your time on some stupid,silly, idiotic person with worthless attitude.... he seems to be very despirate to guide any guy according to him as if he influence the learner's life.. .. in simple words, leave it...!!!!

I'm not aware of any great game building templates for android, so this post only has to do with making your own software from scratch.
I would go to the android developer site, and download the Android Development Tools: http://developer .android.com/sdk/index.html (remove the space)
Then I would read up on Java and try to make increasingly difficult projects. Don't even start with android, get a java book (Java Illuminated and Big Java are good ones) and learn the basics of Java. If you know another language already, that won't be too hard. Then, start looking through the android development website, which has a lot of good tutorials.
Once you have an idea for the game, write it out, figure out what you need each piece to do, and then you'll have a much easier time writing your game, because you'll have specific questions that can be answered by the tutorials or your fellow developers here at xda :fingers-crossed:
Have fun and good luck!

You can try the GameMaker, but you will need to know at least the basics of any programming language (variables, conditionals, loops,...)
Consider learning Unity 3D. Its an amazing tool for both 3d and now 2d games.
You can use and learn Unity in easy way, internet is full of Unity tutorials.

It's possible to learn on your own, but it can be good to have others to either learn from or run your ideas by also. It's difficult to notice you're stuck in a box sometimes!
It's also a good idea to play with the SDK sample apps when you're learning not only Java but Android APIs.

Although it would probably be easier if you were taught it in an educational envrionment (university maybe?) or, like driving lessons, you had an actual android developer sit down next to you when learning/developing I personally think the official android Design and Develop series can take you from novice to intermediate - low end of complicated development. You could use these in conjunction with xda dev or stackoverflow to get any information/code that's missing or you don't understand how to implement.
developer.android.com/design
developer.android.com/develop
developer.android.com/training (especially this one)
Thankyou very much, I will start download source code and test modifys.

Hello, the answer you are looking for is absolutely! You can learn everything you need to by yourself, granted it will take much longer than if you had someone to ask questions.
How do I know? I started programming on Android ~3 years ago, by myself. I had nobody that talked me into it, and I didn't attend any colleges. A motivational spark encouraged me. I had absolutely no programming experience, how it worked, or anything about it. Now, I have 5 apps on Google Play, and am working on my 1st game. All with the knowledge I've accumulated over the years out of pure interest. People laugh when I tell them it's my hobby, I stand serious haha.
For me, youtube (something visual) helped me get started, as you can easily follow along. After you feel you have a grasp on the basics, I started looking online further. Searching this site, and StackOverflow.com are great learning resources. Before you know it, you'll be a master! Good luck!:good:
Firstly, it might help if you describe what is your exact situation. How much experience (not job experience, but coding experience) do you have in programming? How much comfortable you are with any programming language, say C? How familiar you are with OO concepts? Are you uncomfortable just because there's something different with Java, or is it because Java is your first programming language? If you read carefully, the preface of SCJP book says that this book is not to be used to learn Java from the scratch.
Btw, unless you get all building blocks in place (e.g logic constructs - loops, basic data structures, OO concepts etc.) don't go for other stuff like threading, swing, JDBC, xml parsing etc. :good:
You can definitely learn it on your own as long as you have to drive to do so. I taught myself ( I had no computer background). I am no expert but I can get by. And I just released my first multi-player game, Word Cloud Social, on Google Play yesterday. Check it out .

As auric stated, you have to have the motivation and determination to learn by yourself, but it is definitely possible.
Don't rush it, take your time and try to understand it. Analyze everything, and if you have questions search the web, or ask on sites like here right away.
You have to believe in yourself

Of course you can, read a lot of tutorials or watch a lot of video tutorials depending on what you prefer and how you learn best, but most importantly: practice.
I think the best way is to find a simple idea you like for an app, and learn just what you need to create this app along the way, start off with a basic "how to setup an android app project" tutorial and work your up from there.
The android framework is quite wide, you can't learn all at once, I think this method allows you to stay on a defined path and actually achieve something.
And by learning the APIs you need for your app idea, it'll open more doors for you to learn other APIs to improve upon your project, or start a new one being more comfortable with the environment.
If you're more the type of learner which learns best by watching, I recommend you watch the 200 videos series for beginners by TheNewBoston, it's a good start:
https://www.youtube.com/playlist?list=PL2F07DBCDCC01493A
The official training courses and docs can be a bit overwhelming for beginners I think.
If it's something you really want to do, then just practice a lot and stick with it, you'll get there.
Just 3 or 4 years ago I didn't know anything about programming except some very basic HTML, I learned by myself and now I work full-time as a front-end Web & Android engineer at a french startup (IZIPass), on projects for clients such as McDonalds and Subway.
If you're looking for some inspiration, the series about Hacker Schools by former XDA TV producer Jayce Broda is an awesome one.
It shows how Mark Rossetti evolved from a total beginner to being hired by SalesForce in the SF bay area in 12 weeks.
You really get to see his progression as these are weekly interviews, it's great, I know it inspired me a lot. And still inspires me to try and go live in San Francisco, but that's another subject^^
Just make your own "Hacker School" for yourself
You certainly can. I'm still in highschool and I'm self taught. I educational book I've enjoyed reading was Java Notes 6. Its free of charge on his website!

To get interesting app's source codes one could use F-Droid (it's an app store which only hosts open source apps).
And also people with somewhat limited coding knowledge could use APIs to further reduce their efforts.
I found this app very helpful and inspiring in this regard.
I have always been into coding and now i actually want to learn more about it, i made a extremely easy app and i was wondering if anyone can help me get started on what to do with android app dev, i bought a java book and i dont know which sections to read, please help as i do want to pursue this as a career and a hobby.
