How do i create a simple app - Java for Android App Development

I'm totally new to programming & i wanna know what software do i need to create my 1st app .Also,i would like to know what would you suggest as a good start.

Maybe you start with reading some android book. They have some simple examples that you can play with.

I highly recommend you to read a book called Head First Java. Once all your concepts are clear, then start reading Head First Android to know the basics about Android app development. Good luck

You should start with googling Hello world application for android. Next you need Eclipse with ADT plug-in (mostly used IMO) plus Android SDK as dev tools.

That's the book I also recommend to everyone who hasn't got very much expirience with programming. It is easy to understand and fun to read. So get that book and learn Java first. However, you can skip the parts about designing the user interface (UI) as that is completely different for Android.
Afterwards get a book about Android programming. You need a good understanding of Java for that though.
Software which you will need is Eclipse and the Android SDK.

Basics
You need to learn the concepts of Java, (reading the books as suggested) and try experimenting and changing what you've learn through Eclipse

I have personally read Head First Java and agree its a good place for you to start. I had been learning for about a year on and off when I finally picked up the book. It was like a light switch turned on and finally started wrapping my ahead around the things I had been failing to comprehend.
I want to point out to those some things to those that think they are just going to jump in and start developing world class apps. First thats not going to happen. Learning Java and other parts of Android are like learning whole new languages in their own. You have to learn to walk before you can run. But for those that really want to do it, don't give up and you will eventually get there. :cyclops:

You can also find many beginner's java tutorials(they may not be as good as the books). But once you have the concept you should be on your way to app development.

I think the best and complete way is studing the java tutorials provided by oracle and the android tutorials by google.
You can start with the basics of object programming and the fundamentals of java and android.
After, use the advanced tutorials for specific concepts.

In my opinion there are better tutorials than Google's ones for beginners. Too complicated for newbies in my view.

Hi !
I answered your question here. Of course you need to know Java before you start with Android programming.

Is Developing Apps For Android Easy

hi all is developing for android easy. i know prior experience would be great but as a first language would it be easy to pickup.
Do you mean to develop apps for android? If yes, then it is fairly easy, because apps can be written with the Java programming language.
Of course, if you never did any programming before, it will be hard at first. But I think Java is one of the best languages for a beginner to learn.
http://appinventor.googlelabs.com/about/
No need to learn a programming language. Although it helps.

It's possible to use it for Android?
Basicaly , I think that making an app is not hard , but making a good up and keep developing and update it in order to make it even better, is very tiring, and difficult.
And after a point, code is realy complex for unexpiriened programmers.
Thanx for replies. I've picked up Java and android application development for dummies book.always wanted to program its difficult to start because of choosing a language.
I think Java is a good start as u come across Java in PC's and phones.
Is xhtml a big part of android programs. Is that another language to learn.
and last question about the android sdk is there a tutorial on installing it on 64 bit windows seven.I remember coming across compatibility problems with eclipse

Learn or do it the easy way??

Ok guys, im currently learning Java and I'm still learning the basics. I'll say I know about 80% of the basics things in Java. I am really desperate to create my own app and then I stumbled upon the 'MIT App Inventor' (MIT AI). Its basically a simiplified way on creating a android app. Just drag and drop things etc. I reckon I can build my app using the MIT AI since a guy controlled his robot using the MIT AI so I see no reason why I wont be able to build my app using the MIT AI.
But if I use the MIT AI, I feel as if I'm going to to the cowards way. Like I'm not going to build my app using Java but just by dragging and dropping things into place. So what do you guys think?
I'll still be learning Java but as of right now, I leaning towards using MIT AI for now but i'll probably have a guilty feeling about it
Yeah, I recommend learning Java. You cannot do everything with the App Inventor. Basic things can be done with the App Inventor, but very complex things cannot.

I guess for the time being I'll use MIT AI since the app I want to create is not that advanced. But there is a feature that I would like to put in my app later on when I learn Java since that feature is WAY TO COMPLICATED for me to put into my app for now...
How long did it take you to learn Java?
EDIT = Damn, just realized that I won't be able to implement the feature to my app later on since I wont be getting the source code for my app...

You've pretty much answered your own question Through my few years in programming, I've come to realize this: the easiest solution is not always the best.
The drag-and-drop programming environments look good on the surface, however as soon as you start implementing and experimenting with complex ideas, they becoming limiting. These type of environments are ideal for those just beginning and with little desire to advance their skills. You, on the other hand, already seem to know a bit about Java and have expressed a desire to learn more - a simple environment will just limit you.
My recommendation? Stick with Java. Start out with a small project like a calculator, and follow some tutorials. After you've grasped the basics, try jumping into a complex project, where you're forced to learn. I can vouch for this, because it's exactly what I did. I started with a few simple Android app and then worked on a bigger project. I googled, used StackOverflow and followed tutorials and learned a lot along the way.
Hope this helped, please feel free to ask anything else!
Yeah, im just self teaching myself Java. I know a basic C++. I dont really want to study computer science in college/university since the fee of the course is so overpriced for the course and to be honest, I see no point in studying it since you can learn off from the internet. Thats just my opinion. I dont really have a problem with people going to university to learn CS but I personally wouldn't.
I'm really just self teaching myself computer science. I know decent knowledge about hardwares in computers. I built my own computer back in '09 and still is running like a pro
The thing that is putting me off from learning any type of computer language is the time it takes to learn... I guess I just gotta be patient and keep learning.
So have you published any apps on the play store?

No, I have got no apps out there, but I want to release one soon.
I learned Java by reading (without testing) the book Head First Java. However, I had some Delphi and Python programming knowledge.
This book is really great. And it is fun to read it.
Learn, that's what it is all about , and it's going to be great fun too

yep, im just currently following the bucky tutorials (thenewboston.org) right now. Ive actually got that book and read a few chapters. Its a good book but I didn't understand some parts of it. Thats why im going through all the bucky Java tutorials and then going to read the book so I have a full understanding of Java.

Sounds like a good plan.
Happy coding!
hey there. Im currently having difficulty learning about event handlers. I know what they do but im just confused on how to use them.
This is the framework of a typical '.addItemListener(){}' method:
.addItemListener(
new ItemListener(){
public void itemStateChanged(ItemEvent event){
}
}
);
I dont know what those keywords mean or when to use them. Could someone shine some light on this?

When you programm for computers, you need ItemListeners to get informed when the selected item of a JComboBox changed.
That means that the itemStateChanged method is invoked when the user selects an item.
However, you do not need them when you learn Java for Android. You do not need Swing and AWT at all!
Skip everything related to the UI as it is different for Android.
Ive been spending most of my time recently learning about GUI in Java... I feel wasted.
Thanks for the help though. Much appreciated.
I'll probably still finish the bucky vids and then move onto the head first Java book. Does that book contain everything I need to know in order to build a successful app?
I also came across this website. Seems much better and more easier to understand than the book I have:

The head first book explains Java. It explains object-oriented programming very well and tells you everything you will need to get started with Android programming.
As soon as you have got Java knowledge, you can start with Android programming. You need Java for Android programming, that is what the book (and your link) explains, but it does not explain Android programming. I recommend this site for Android Tutorials: http://www.vogella.com/android.html It is great.
In a short form: Java knowledge are the basics, Android related things require Java knowledge and are related to the special conditions on the device. Therefore they have another API for the UI, background services and other things.
Btw, I needed to learn the Java UI things later when I wrote a desktop application. You did not waste your time. Your knowledge will be helpful later.

Ok, the vogella tutorials might not be the right tutorials for you.
However, I do not like the official training sites. They are too difficult for beginners in my opinion. I would not start with these.
Some like the new boston videos: http://thenewboston.org/list.php?cat=6
(They are many. I do not want to intimidate you, but I thought that I should mention them as you like video tutorials. Don't worry, you will not need to watch even the half of them. I would recommend to watch the first ones and then watch the other ones if you need their content. SQL or WebView operations are unimportant for a beginner. )

Yeah, I gotta admit, when I looked at the android sections I felt as if I wont even have the chance to build an android app since theres over 200 vids and theres too much to learn but then you said I wouldnt even have to watch nearly more than half of them so that lifted up my spirit
But im just wondering, how long does it actually take for a person to learn 'enough' Java to start making a android app?

That really depends on his experience. I had some experience and I read the head first book and started. Of course, I learned afterwards, too. And of course, I am still learning. You do not need the UI things and stuff like this. You should understand Collections, inner classes and interfaces, though.
In case of doubt, start with the Android part and if you do not know something related to Java, search what it is. Learning by doing.
However, I cannot understand the order of some of the videos. I think that ToggleButtons (23) are not as important as RelativeLayouts (44).
Just finished watching the beginner section of Java from his vids. Probably going to watch the 'intermediate' vids tomorrow or probably forget about watching the vids and just read the book...

I must say, stick it out the hard way. Automated-app builders will not teach you anything.
I say this because I myself have been developing Android apps for ~2 years. I had NO prior experience or knowledge in how any programming language was used or written. Now, through determination, I have 3 (still learning, so still basic) apps on the market.
I have self-taught myself Android(java) with the help of a few YouTube videos. I also learned some SQLite which will be used for all android databases, XML, and HTML. All which I have implemented into my apps.
So what I guess I'm trying to say is, if I can learn all of this in ~2 years by myself (albeit you'll run into many educational mistakes) then nothing is impossible. I didn't even make it through high school shamefully.
Regardless, knowledge is power. An auto-app will not do any justice IMO. Android is not the best starting point, but if you already understand programming logic, you should be alright.

Learn my friend! That's what XDA is about.
I'd say definetly get familiar with the general activity lifecycle, learn some basic things like intents and such, then think about something simple you want to try, and find out how other people are doing it. (Look for guides, or study open source apps etc.)
i've been teaching myself over most of the last year and am super impressed by what I;ve managed to figure out how to do. I still got years to go before I'd call myself a "good" developer, but just keep pluggin away.
It all depends on how you like to learn too. I read tons, and tried watchign videos, but I do much better by just jumping in and fixing errors as I go. then before you know it, you'll be able to do a lot of things. For me I found it became a lot easier when I started breaking stuff up into single parts. like If I want some app with a listview that goes to a webview, I'd make a simple Main Activiy with a list view, then make a new project with just the webview, then worry about linking a couple things together.
Every body learns different though.
Good luck!
(plus I think MIT, even though it's a neat idea, just helps to clog the playstore with junky apps.)

Which is the best book for Android beginners ?

Hey guys, I want to find work as either a freelance android developer or even make money by developing my own apps. I started from zero only a month ago. I now have an acceptable knowledge of Java - I am familiar with most concepts. Now, I am starting Android ....now which book do you think I should start with ?
1. Busy Coder's guide to Android development by Mark Murphy
2. Beginner's Android 4 Applications by Wei-Meing Lee
3. Professional Android 4 Applications by Roto Meir.
I have bought all 3 books. But I wonder which I should start with before I move on to the next. Mind you, I am not a skilled java programmer shifting to android like many of you here. And how long do you think does it take for an average novice programmer to gain acceptable command of Android and develop apps ?

Learning programming is nothing you can do casually. It can take quite a while.
However, it depends on what you define as good knowledge. You will get really good coding skills after decades of programming. But don't worry. You won't need skills as good as a professional developer's skills at the beginning. (And I don't claim to be as good as one of those old folks I described.)
It also depends on what you want to do. Some things like server communication are more complex while other things are easier.
I hope that this didn't discourage you. If you start with small apps, I am sure that you will be able to learn that. Coding is nothing magicial.
I'd start with book #2. I think that you can skip a lot of chapters of book #3 afterwards. I wasn't able to look into the first book on Amazon, but I think that I'd take that one as the last one.
However, make sure that you understand Java first. Without Java, the base for Android programming is missing.
I am sure that you can manage that. Enjoy it.
I'd also recommend book 2. It's very good for basic stuff.
I don't know any of these books, but i would also recommend you Googles Android Developer Site:
http://developer.android.com/training/index.html
There are great tutorials and all concepts of Android Applications are described in detail and quite easy to understand for beginners.
Thanks guys, as you suggest, I will start with book 2...

Android is an open source and Linux-based operating system for mobile devices such as smartphones and tablet computers.
For writing apps for Android is more than just learning code syntax. If you've never learned to code, you can check out plenty of resources online.
There are plenty of eBooks that are available which provides clear depth tutorial for creating Android apps from scratch.
I would like to recommend you one such eBook where I am sure you would get benefit out from it.
Here is the eBook link @ learnsauce.com
The best programming language for beginners is Basic4Android (similar to Visual Basic).
Check out for my ebook on Amazon:
https://www.amazon.com/Game-development-Android-example-creating-ebook/dp/B0777PSGJZ
and start coding

Best Way To Learn Java?

So I'm just beginning to try getting into development and saw from several users on here that the first step would be to learn Java, so my obvious question is what's the best way to do that? I have little programming experience. I believe I correctly installed JDK and also have Eclipse and AndroidSDK. A brief but clear explanation pointing me in the right direction would be appreciated. Thank you for anyone who can help.

The first thing you should do is ignore the AndroidSDK for a while !
It's not worth touching a phone before you can at the very least write a few simple Java programs.
Start with a single class that prints some stuff out to the screen and go from there.
Once you are comfortable with the syntax, I'd say you'd need to be able to write a standalone Java program that has, say, 10 classes in it as a first step.

Thanks for the advice! I'd definitely agree that I should be able to read and write at least basic code before putting anything to use, however where should I learn how to write the classes? I downloaded the Headfirst Java textbook because I saw people talking about it and seemed pretty legit. Do you know anything about it or how to go about using it? I can't seem to open the .class or .java files even though I believe I correctly installed JDK. Is there a better place to learn? Thanks for any help you give, clearly I'm new to this, however very interested.

So I'm just beginning to try getting into development and saw from several users on here that the first step would be to learn Java, so my obvious question is what's the best way to do that? I have little programming experience. I believe I correctly installed JDK and also have Eclipse and AndroidSDK. A brief but clear explanation pointing me in the right direction would be appreciated. Thank you for anyone who can help.

If you want to learn java for android application development then i would refer you to thenewboston
They have 200 videos for Android Application Development starting from the basics.

Hit Thanks :good:
Thanks both of you. I've been looking at the official tutorials on Oracle but some videos would definitely help too. I have a little programming experience so it's making sense to me, just trying to get all the terms right. Videos will help me out with the explanations. Thanks again!

Yeah, if you want a book, I can recommend the Head First Java book. That's how I learned it.
You can also have a look at the Vogella tutorials, especially for Android specific things.
One tip: If you learn Java just to be able to develop for Android, skip the UI parts. They are completely different on Android.

Sounds good, I have already downloaded the Head First Java book, however I haven't been able to utilize it as of yet. Am I supposed to compile the lessons first? Run them with Eclipse?

In my opinion that depends on how much knowledge of other programming languages you have.
If you already know how to use for/while/do-while-loops and if/switch-conditions, you might want to skip those examples. Do it just if you're sure you don't need them.
I didn't run any of the codes. (Wanted to start with Android as soon as possible. :laugh I learn very well just by reading on programming languages because they are basically all the same. So it's not difficult to learn another language if you already know another one.
However, I ran the examples in the books I used to learn my very first languages (Delphi and Python). I just skipped them for Java.
Decide whether it will be helpful for you. If you're in doubt, run them.
The textbook for JAVA in our college is 'Starting out with JAVA' by Tony Gaddis and its really very good for beginners. Just give it a try.
Just read the tutorials, create a new project and start tinkering around. If you have questions, ask them in appropriate java forums.

Now there is a TheNewBoston Android app as well https://play.google.com/store/apps/details?id=com.Thenewboston

Can I learn by my self?

Hi, I dont know java but I know a little about Eclipse and make apps.
But I nedd know if is possible learn by my self.
And How??
Thanks

Well you really need to know Java basics, and then just start learning off the getting started guides on the official site

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.

YES YOU CAN
The best place to start would be to download and import the source codes of very simple open source android apps, read them thoroughly and then start making little modifications to it to learn what code affects what part of the app's functionality, try adding new functions and features. This way you will learn and build up your confidence.

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.
Android Developer official Israel very difficult for me.
But thanks

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 .

Wow, thanks for your words, inspired to me.
A friend teach me a little and gime me a source code of a theme pack and I know change the image and customize this, but I need learn more.
Thank youvery much
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.
