Need help programming - General Questions and Answers

Hi I'm using eclipse and the app called Terminal IDE and I need a push towards some android apps source code I can ply with to help learn more complicated code. Please help. Also any good places to go to learn more about java would be nice. I'm not even out of highschool yet and want to get a jump before college starts. I learn very fast if not presented with material to high. Currently I understand how and what stuff does in building the hello world app

[Q] Requirements for basic app developing for a dummy

Hi,
I wanted to know what are the skills and languages you need to know for android app development. Currently I have zerrooo knowledge about app development n all. I havent studied computer languages ever so I have a few Questions
1. What are the skills or languages you need to learn to start with?
2. Can you learn it at home with books or ebooks?
3. How long does it take to learn a language e.g C++ (I know it takes alot of time so i'm ready for it )
Please answer these n help me from where i can start learnin from ultraaa basics
Thanks
It will be a long time, but it's not possible.
You have to learn Java and XML to develop for Android. I think you should practice a lot with writing apps for pc and after that you can move on to Android.
For your second question I have to say I learned everything from books. There are a lot of them on the internet too so you don't have to buy if you don't like.
Learning a programming language takes a long time, there are some books which says you can learn it in 24 hours, it's true, but you won't be able to create your own apps. For this you will have to practice a lot, but it depends on you have much time does it take. (Learning XML isn't as hard as Java, but you should learn Java first)
Thankssss alot for your help...im looking forward to start with java...btw is c and c++ necessary for android dev?

If you want to write android programs you don't need c/c++, however you can use them to make your program run faster, but it is for programs like 3d games.

Soo can anyone guide me dat from where can i start learnin java?? I dun av even da basic knowledge about any language so keep that in mind from where should i start?
Sent from my Nexus One using XDA Premium App
There are some tutorials on the website of java, but I never used them so I don't know how good they are. I can recommend you reading a book, maybe "Teach Yourself Java in 24 Hours" is the best as it starts from the beginning of programming.

Thats great so ure sayin it starts from the basics like even the definitions.of what a code is lol
Sent from my Nexus One using XDA Premium App
Something like that, but almost every programming book is like that. It will tell you how to write, compile, loops, data structures, oop and anything else

Thank you, it would be help.
imho, to be able to write good aplications, you need to be gifted, I was learning PHP for two years, I was doing some Pascal, Delphi, C++ and Visual Basic in high school, and I knew the basics, and I could imagine how it works and how do I need it to work, but somehow, I was never smart enough to get more complicated apps to work, no matter how hard I tried... my brain just probably doesnt work that way... :/
Maybe your, but as I have never had any problem I thought everybody can learn it. However everybody should try and if he isn't "talented" he can stop learning it

Dev help

Hey all, I wanted to start Android app development as a hobby. I am very comfortable with C++, but I know that Java is necessary for Android. What parts of it will be important, and could you please recommend a good tutorial? Thanks.

I have been trying to get into making live wallpapers myself. I have been asking everywhere about what I need to learn to make a live wallpaper. I have no idea where to start or what to learn. I have posted several threads and ask devs in the market to & no one wants to tell you anything about where to start or what to use. I really don't understand why no one wants to help, especially here on a Developers website. Hopefully we can get a Senior member to give us some good tips.

[Q] How to build an Android App ?

Is it possible to build my own android app (even if I am a noob with no real knowledge of programming)?
I know of "App Inventor for Android", but it barely has any options from what I see
):
I basically want to build an Alarm Clock for myself
(and maybe other will like it too)
THANKS

To make an Android app, you should learn java. Then look at the documentation for developers on the official Android website. If you do not know how to code, then you will end up with some premade app, that gives you little customization as to what it is. I do not know how to code but when I have the time, I will learn.

Where does one learn how to code? Is that something people learn in Computer Scenic degrees?
just wondering...
Use this video to learn.! Its much easier and from a reputable source.! Its an hour long though. They explain very well, I thing they also have a rom development vid also.! Subscribe to them.

Thank you!!! the Link is broken though
The code is written in java. Learning java (plenty of books and websites out there to learn the basics) is step one. Downloading the android SDK and Eclipse or Netbeans IDE is step two. That's it. Once you learn the basics of java you'll know what to do with the sdk and the ide, both have detailed instructions in the programs help section to help, as the "hello world" script is their beginners walkthrough example. Also, there are some good video tutorials on you tube that walk you through the entire process from getting the SDK to posting your app on the android market. As is the case with most questions, google is your friend, and you tube is his brother.

Hey (The new Youtube is very convenient, this new link is a link to a bunch of videos) I am currently studying these videos and find them EXTREMELY helpful, this is a more visual approach, because like most, reading words for 3 hours doesnt work, and apologies for the previous link, I sent it from my phone!
Check out these vids by MarakanaTechTV HERE
Thanks so much !
No probs man.!

Do a forum search and you'll get a more detailed answer as its been asked before but basically there are at least two answers.
Java, using an ide such as eclipse as android is java based.
Or basic4android if your used to the basic style programming languages like visual basic on pc or if java seems hard to learn.

Oh and also how should I go about learning, is there a super website or something?

I would say Java for sure with Eclipse. I use thenewboston.com for java android tutorials.
Start here:

Well it would be better if you could give more specific info about what error you get where exactly you are getting stuck while installing it.
Here's a link to a tutorial to set up eclipse.
www.vogella.com/articles/Eclipse/article.html
This is probably the wrong forum for this kind of a question. Not to mention that threads here just get lost really quick. You might want to try the Q&A forum next time.
I am guessing you might not be knowing much about programming either. So instead of trying to make a game at this point focus on learning to program. Search for Java tutorials on youtube and google
The errors gone and i have my first app. So plz help with a game app.

Here is a simple open source game - https://code.google.com/p/newtonscradle/
Really, your approach is just wrong.
Nobody can help you if you don't know any basic of java programming (at least).
First of all you have to read java and android documentation, then open some tutorials in eclipse and play with them, then start with simple apps and progressively make it more difficult. At the end you'll be ready for a great game.
There's no short way unless you want cut and copy stuff and don't care about learning something.

Theres more to a simple game than to a simple app. Start by buying a book on Java if you really want to get serious about it.
If you just open up that open source project linked above or maybe any example game in the SDK you'll see how complex a simple game can really be for someone who is new to programming.
Make a text based Mafia game, I don't think there are any of those yet.
I don't want to upset you but if you jump straight to the android without a basic knowledge of object oriented programming the learning curve can be quite steep.
As said above, the best thing to do would be to get your hands dirty with basic java coding first.
I read this before jumping to the Android world: Introduction to Java Programming by Daniel Liang A much recommended and well-written reading.
I know java basics
