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.

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:
http://mobile.tutsplus.com/series/learn-java-android-development/
Your thoughts?

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.)

You're stuck getting Hello Android to work or whate to do after hello android? Do you know any development languages such as Java or C#? (you'll be writing android apps in java, but C# is really MS version of java with a few syntax differences) If not, are you familiar with object orientation? If not, it's gonna be tough dude but if you're smart and pick stuff up quickly you can learn by reading.
Pick up some books and look at youtube videos.

There's a few free Eclipse and Java books out there that a beginner will understand especially if you already understand the concepts of object-oriented programming. Eclipse IDE itself will need a book as it's full of plugins and tools you need to understand to compile your project effectively.
It's going to be a very very long and slow road.
This may help, a series of YouTube videos for beginners.

I've been thinking the same thing, learning to develop for Android. Since I have near zero experience programming (save for a VB class in college) I decided I would be better off hiring someone to write what I want.
Just keep in mind though, Hello World is just where people start.
You may want to check out the android Appinventor. It's made by Google, and is in beta testing now, but it's a graphical way of programming for android. Though there isn't any code involved and won't be good/used outside of Android, it does a good job imparting the logic of programming.
I'll give you some tips that I've learned over the years as a developer.
First if you haven't done any development before I highly advise obtaining a book. True there are tons of web tutorials out there but personally I find a good author can do wonders in learning how to develop software. Anytime I want to learn a new platform I pick up a book on that platform. Of course you can find a ton of books used but another great source is a library. If you're in college with a computer science program chances are your library will have a couple of books on Android development. Your public library probably has some books on the subject as well. If all else fails see if you have a friend who will loan you a book.
Reading about development is only part one, part two is hands on. You can read an entire book on developing software and walk away with no knowledge. You can mindlessly follow the examples in the book but I find it best to use the examples in books as a guideline. In other words take the idea in the book and morph it so you're working on something original. Trust me here, you'll learn a lot more doing this instead of just mindlessly following the examples.
Next thing you'll need is a problem. Why? Because you need something to write. I find myself most motivated to write software when I either have a problem or something else has one and a checkbook. What do you want your phone to do? Are there applications out there that solve your problem but you think you can do better? Think small and easy since you're still new. Realistically you're not going to be able to make a web browser from scratch as your first project but you can certainly make a database of movies you own.
One thing that is debatable is whether you should learn to write something quickly or well. Frankly I'm in the school or writing something quickly and ignoring "correctness" when you're new. People new to programming spend too much time worrying about doing things "correctly" (very important when you're developing actual software) instead of learning how to do things in the first place.
Your code may not be readable, may not be optimized, and may crash every time an invalid input is entered into a field but you'll learn from those things. I think most people who end up hating programming do so because they spent too much time on worry about the little things and thus seeing no results for their work. Once you have the basics down you can concentrate of the details of optimizing code, validating inputs, and making your code readable.
Honestly not matter what you write you'll look back at it in embarrassment ten years from now anyways.
Ok thanks will look for a book

Buy a Java book that also covers Object Orientation basics and principals. (you'll also need to understand some XML to do android programming) If you want to make kernels/ROMS, definitely look into Linux and shell scripting. (you can find most of this info online though)
By the way, I heard the "Java in 24 hours" book is pretty good.

it might be good, but it wont teach him how to actually code. Most of those books are made for people that know other languages like javascript/php/c/etc.. and are wanting to move to java and learn the new syntax.
I have no idea as to what you know. So ftw.
Write what ever you decide in a pseudo code, first.
Two things will fall out of that, a design, and java methods of implementing the pseudo language ( as you decide what java syntax does your psuedo code) which invariably returns you to (1) the design. I think it's called iterational refinement, or some such other bs.
So don't get bogged down, now that you know hello, make it start "right"...
You all do realize that eclipse was a machine.. a sunny>dg joke.
I have been a member of XDA for a while and now I want to contribute. I have a basic understanding of computers and want to learn more. Obviously our greatest devs were not born devs they had to learn everything from somewhere. I'm looking for suggestions on where to start on the road to become the best dev I can be. Keep in mind I'm flat broke so I cannot hit up the local bookstore or download any paid software, but with the way the internet is today there must a free legitimate source for everything somewhere. So anyone willing to help a noob If I posted in the wrong section please kindly redirect me rather than flame me. Thanks in advance.
It all depends on what you want to contribute. I'm a beginner myself (only developing since august). It is easy to learn Java, for the most part. I would suggest heading over to http://developer.android.com/index.html for starters. There are many examples and if you want to know something specific, try using the search bar at the top right (it comes in handy). I have already published an app, a simple one, but still an application none the less. I am working on two other projects simultaneously (a live wallpaper and a home-replacement app). You can come to my website http://futurinnovations.blogspot.com/ to see what I'm working on. I am still in the process of learning, and being in college slows things down a bit. Just make sure not to give up. If your stuck, ask someone (or everyone) on forums like this.

porting and building is something far different from app development...you have to know much more if you want to work with kernel,drivers,basically you have to know everything from hardware level to user level (if you want to be top of the class)...good luck

Well we all gotta start somewhere. Now is probably a good time for me as I'm only 18 and a senior in high school. Since I don't have a job at the moment I have plenty of free time after school and on weekends.
I'm only 18 myself. I started straight with downloading Eclipse and all of the appropriate software for developing and just dove in. I would recommend watching these tutorials: http://www.xtensivearts.com/topics/tutorials/. They helped me A LOT. I am taking a programming in C class in the spring semster, which I am looking forward to. Programming in Java for Android is different than regular programming. It's the same concepts, just different APIs and tools. I like using Eclipse because it is easy to learn and get used to. There are a lot of fancy features like a type of autocorrect (not like on the phone, but smarter). Like you said, just start from the basics, like "Hello World" (Hello Android) and practice creating different layouts using the tutorials given on the Developer site. Explore the site and look through everything because eventually you may need to know where its located for quick access. Just don't set too high of goals for yourself, other wise you might be more prone to give up (like I almost did). Good luck

Hi, I'm 24. And I learn how to 'program' since 14-15.
It's easy to write apps for Android. But it's hard to write good apps.
You should take Software Engineering course (NOT Computer Science course).
If you take CS (Computer Science) course, than you will learn mainly about algorithm.
But if you enter SE (Software Engineering) course, you will learn about SDLC, software QA/testing, and planning to write programs for living
:-D
I personally don't like eclipse, it's just bloated IDE :-(
I use SciTE, apache ant, MinGW/MSYS (GCC 4.5.0), Java SDK, ActivePerl, Dev-C++ IDE. That's should be enough for development :-D
I will see if there are any software engineer classes at the college I am attending. If so, then I will sign up for it. Thanks for pointing me in the right direction. Is taking the programming class still beneficial?

I'd really recommend a class if it's a viable option. It will help you understand object oriented programming, where just working through examples won't actually teach you how to understand what you're doing. Things like classes, inheritance and polymorphism are pretty difficult principles to grasp unless you've got someone to explain them to you. Then it's pretty easy.
How does one begin developing apps? Can anyone point me toward the right direction/programs/info? If I purchase the Nexus S, I would like to start learning how to.
Appreciate any help/advice to get me started.
Even I am gonna start it soon. But I guess this should be good starting point

Learn Java or some type of programming language to help you understand programming and etc. Then once you start reading the Android SDK again, everything won't seem like a foreign language. Well, shouldn't anyways.

But I am also in the same boat, starting out learning to program in Java. I have dabbled in a bit of HTML (self taught, don't know much), so that's about the extent of my knowledge. But if I did learn Java to write apps, how useful is it in say creating ROMs? Like if you were to fiddle around with the Android source, what language would most of it be?
Sorry if that has been answered before, I did search Promise, but nothing seemed to come up

I co-sign head first Java. Once you have a decent understanding of the java language you should pick up Reto Meier's book, Professional Android 2 Application Development. And read the developer.android website extensively. I can assure you, you wont be developing apps tomorrow. It will take quite some time. Be patient, read thoroughly, and re-read things you don't quite understand.
Also, if you don't learn well from books, take a few java classes at a community college (or a University if you happen to already be there).
Hello XDA,
I have just finished my first year of high school, and have spent 2 years around Windows Mobile and Android.
I want to start developing in different parts of Android, Applications being the top priority.
I have found and got many guides such as Sam's Teach Yourself for helping me build applications.
I know I can't start off building advanced apps. But the place I need help is where should I start, and what things I should learn such as Java, Adobe Air being a few.
If you guys can please maybe make a list I should follow or something...This would be greatly appreciated,
Thanks A lot
If you have an idea about java, the next step is to "google" for "Android Developers"...
I think it's the perfect place for beginners in Android Development...♫ ♪
Yep, you'll definitely need to learn Java. Knowing some Object Oriented concepts will help too.
The recommended IDE (Integrated Developer Environment) for Android is Eclipse (it's free!). I personally use IntelliJ (community edition is free - less features, but it's got all you need for Android dev).
Looking at tutorials etc is really good - imo the best way to learn is hands-on learning. A good starting place is the developer docs: http://developer.android.com/resources/browser.html?tag=tutorial
Once you've followed a couple of those, you'll probably be exploring new/random classes, so looking at the reference will help too: http://developer.android.com/reference/packages.html
Of course the best way is to just try something out to get started - even if it is something simple, or verbatim from the tutorials.
As for what app to start with... a simple one is always good. But what is important is make something that you feel like you need/want to use yourself. That way you will be more motivated to follow through with the idea, and you'll be your own user, thus be able to make good improvements
Thank you so much
Thanks a lot. I would have no idea where to start, despite many guides available out there.
Both you have made it a lot simpler.
Thanks once again.

No problems
Oh, forgot to mention in my original post... the only reason I'm using IntelliJ is because I use it at work (so used to the shortcuts etc).
imo, both IDEs are comparable - just what you are used to.
If you haven't used either, probably go with Eclipse since there are a lot more tutorials/guides out there related to dev with Eclipse/Android.
I started developing about 8 months ago. I am going to be a Junior in High School, so we are in the same boat here.lol
Anyways, I spent a lot of time looking at many books and resources. Alos another thing that helps is to teach your self how stuff works by studying source codes. But dont only do this. Look at tut's and other resources as well. Remember, start small then work your way up! Dont go out and try to make a super amazing awesome app. You will just frustrate your self. So start simple. I was making small apps that only had text when i first started. Now where am i you may ask? I am the developer of the Android Markets only Honeycomb Launcher and a couple other larger apps!
Just remember it takes time, alittle money, patiences and PRACTICE! Make an app or at least work on an app EVERYDAY if possible.
If you get stuck use the resources on the Android site that Android gave to us.
http://developer.android.com/guide/topics/fundamentals/activities.html
Check out the DEV guides, resources and sample code.
Also, do you have eclipse and Android SDK already set up?

I finished my 2nd year of high school, got an HTC Sensation 4G recently and am looking to make roms for other phones (currently looking at the Nexus S). I am getting bored so I would think it would be awesome if we could team up of something and create some roms for phones or something. I'm young like you, looking to make use of my general coding skills(had iPhone for 2 years, so i have some experience with jailbreaking and modding, etc.)
Would be very glad if we could team up or something and who knows, maybe become the next Cyanogen! Looking for a hobby, not profit.
Have a good day!

Creating a ROM right off the back??? You are going to end up throwing your computer out the window! I know a few ROM developers and they say it is VERY challenging and frustrating at times.
I recommend you two join together or with others and create some apps first. Start small then work your way up...

i concur... The Android operating system, including the Linux kernel, consists of roughly 12 million lines of code including 3 million lines of XML, 2.8 million lines of C, 2.1 million lines of Java, and 1.75 million lines of C++.
wrap your head around that... =)
depending on how complicated you want to go, you can try using phonegap or html5 to create apps, if not, you would need to learn java
PS: you want to make a rom from scratch? what?
Thanks to everybody above i really really appreciate it, i learnt a lot of nice advice.

That is A LOT of code!!! You guys should probably start with the "Hello, Android" tutorial. That can be a challenge if you dont know how to work eclipse. But luckily, Android provides a nice little "Hello, Android" tutorial.
P.S. You or anyone will never past Cyanogenmod for awhile. I think they know what they are doing.lol
But it is always good to dream big! Like i want to be a Trillionare.lol (I dont even know how to spell it) "But dreams do come try"
Hey guys, I'm a senior now. I have done the hello Android tutorial, and I have the Android dev for dummies, but I know nothing about java and xml programming.
Thanks for the advice. If anyone else has any other tutorials, let me know. Thanks.

I am in the exact same position as you. I have just got the "Head First Java" book, but I dont think it looks like it will help that much.

See i was in that boat like you guys were, and it SUCKS! All of the tutorials are very simple textviews and buttons, but nothing that really teaches you all that much java.
Heres what i suggest. Play with the source of apps. Download some source codes and create new android projects in eclipse from THAT source. (LET ME KNOW IF YOU NEED HELP WITH THAT)
And with in those projects, view all of the sources and xml files. Learn how stuff works. such as imports and buttons and permissions. I first started messing with layouts, xml files, strings, and buttons. This is good, BUT you will get to a point were you will see force closes. Thats because the java must match... That got me into looking at the java files more and more. Now that is almost the first thing i dive into.
Like i said along time ago, i am not anywhere close to being an expert at all! But i am getting a good handle on Android in the following ways...
- Visit XDA daily and other sites. Stay up to date and learn what is going on now. not what was being developed a month ago. Stuff is aways changing!
- Surround yourself with a group of developers! They can and will be your BEST friends! As many of you had said before, many of you want a hobby not a profit. Trust me, thats what everyone says.lol. There is some good money to be made out there!!! Some of your best developers can make every developer on a team some money. They also have your back if you get lost or stuck on something.
- Try finding people in your same boat or position. Kind of like the other kid on the site... You two can work something out. Exchange emails. share names and interest. This doesn't mean y'all need to hold hands but just create some chit chat once in awhile. If you learned something, tell him about it!
- USE YOUR F'IN RESOURCES!!! Android/Google made this AMZING site called Android.com. On that site they have developer guides, resources, tut's, and even sample code! Another amazing resource is Stackoverflow.com. Here you can find a lot of answers to any problem. I must have visited that site 1000 times.lol
and dont forget about GOOGLE.COM. ask questions in your search, but be SPECIFIC. Be sure to include "Android" in your search so you can get android support not some iPhone or Windows support...
Anyways, just get out there! try to be the best you can! Absorb as much as you can. LIVE ANDROID! but also have a life.lol

very true. i had been a java programmer for 4 years prior to learning android dev and what really got me going was coming up with an idea for an app and moving to make that a reality. if you just go through and do tutorials you wont get as much out of it as actually trying to make something you can use, be it a small and simple something.
also, i had always done command line java programs and had ignored the java swing ui like the plague, but android has a great layout and ui system. if you are learning java for use in android dont be disheartened by javax.swing package
You should definitely learn an object oriented programming language first before delving into android. I would recommend Java as it is what you will use for a lot of development. A lot of these guides and tutorials including that dummies book expect you to know what a public vs private class is or what inheritance is.
Also another big part of android is XML. At least learn the basics of XML.
I recommend the Java for dummies book as it provides a good introduction to many of the Java concepts that you will need. Java and eclipse can be quite a lot of fun once you get to know it.

If your a starter, I recommend to go for web based right way, I'm confident that in the near future most mobile device applications will be mainly web based just like desktops.
Thanks a lot, I will get that book asap.

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.

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.
