What do i need to know

if i want to programm an app for Android.
Is it Java or C++ ? I read that with the new SDK you can use C++ is that right? Or can u only use it for some special parts?
Sry for this noob question:_/

I suggest you invest in this book,
http://www.amazon.com/Android-Application-Development-Dummies-Computer/dp/047077018X
The Kindle version's probably a little cheaper.

android development is done in java unless you want to use the ndk

You don't need a book, just go to developer.android.com.

Hi,
thanks for your replies.
Do i need to learn Java seperately or can i start with the dummie book?
Why i dont need java for the NDK?
ok i saw that i can find there (developer.android.com.) some Tutorials and sample codes. But if i know nothing about Java - is this the right start? Or was i just in the wrong section (i was in resources)

If you're good with c++ then learning Java should be pretty easy. In fact extremely easy since you don't have to worry about memory management and the whole pointers/references/etc thing is straightforward in java.

So your response according to the question i throw in is, that i need to learn Java first, right ?
I'm not good in C++ I just started once, but didn't read more than the first 100 pages in the book xDD
If there's nobody you can talk to, about programming - it's kind of boring and isolating D

Yes definitely learn java first Don't worry about c++. There are many good, free online java "books" that are great for learning. Once you are comfortable with Java then you can go through the tutorials on developer.android.com
Good luck!

While I admire anyone wanting to learn how to write code, it's a little more complicated than that.
I'm a professional programmer...I know how to code in about 6 languages and picked-up Android about 3 months ago. While any programming is hard, developing for a smartphone is even harder in my opinion. I consider myself a complete beginner in Android irregardless of my background.
Programming is so much more than reading a book or some online tutorials. If that was the case, I would pick-up some books and become a plumber or electrician etc.
My advanced COBOL class started with 25 students; there were 10 left at the end
(and I would say that about 5 of the 10 were "pure" programmers)
That being said, it can be done...be prepared for a LOT of hard work, time and dedication. If you make it, it can be one of the most exciting things you do...creating something out of nothing!

Well sure, there's more to it than that, but where else is there to start? I started coding about 10 years ago, first with BASIC on my TI 83. I then picked up a few books on Java, C, Python and C++ and worked my way up from there. I haven't developed for Android yet, mostly out of lack of time, but I'm sure you're right in that it is probably more difficult. However, to say coding isn't more than reading a few tutorials is, to me, not correct. Unless you have the means to pursue CS classes, there's no other way to do it than to pick up a few books, read a few tutorials, watch a lecture here and there and just dive in.
It's easier now than every to learn how to code and you shouldn't try to discourage someone who is interested from diving in and seeing what they can write. Who's to say that you can't read a few books and become a decent plumber or electrician? I built up my car from books and wired houses from reading a few books and talking to electricians as well as learning how to design, build and solder circuit boards entirely from online resources.
I do agree with you though, in that learning how to code is a long and difficult journey that requires a lot of patience and hard work. You're going to have to invest a lot of free time if you want to learn properly, but trust me, it is completely worth it!

I really tired to make my point that it's not impossible and to not discourage anyone. It's "easy" to create a smartphone app as they are fairly short...get into some 20k, 40k, 100,000 lines of code programs and you will soon learn about complexity
To be more helpful:
1. Start out with the basic "Hello World" app
2. Create a program that takes some user input and writes it back out to the screen
3. Keep expanding your coding experience with new topics and Android features
For books, I really like 'Professional Android 2 Application Development" by Reto Meier For JAVA and C++, I don't think you can beat the Deitel and Dietel books.
Look for them on Amazon and then check "Prices New and Used". I got a brand spanking new "Objective C for JAVA developers for $1.99 + S&H!...like $5.00 total

I've heard head first java is a good book and was going to pick it up. Any thoughts? Has anyone else bought this book?

LOL I started as kid with BASIC and TI83 applications, too.
IMO It's not learning the languages that's so difficult, it's learning how to apply what algorithms, data structures, etc to solve a problem. Then there's the really involved details such as how compilers, OS managed memory and synchronization, etc work.

YANPAT (Yet Another Noob Programming for Android Thread)

Good afternoon,
I want to start learning programming for Android, as I am sure many before me have said. And as the title very well expresses, I am completely virginal in relation to programming. OK, some years ago I punched some Delphi lines, but what I learned about it can be amounted to zero
In order to commence the task, I count with a netbook, running Ubuntu 11.04, an Android phone (Xperia Play) and an Android tablet (Advent Vega), two "starting in Android" books, HTTrack in order to save websites for offline reading, a vacant summer, and the enthusiasm to learn something new. I don't have a specific goal in mind (is that a problem? Should I aim for something concrete to do as well?) but I think that, if I win certain knowledge, I will be able to create a useful app to share here.
The reason why I've opened this thread is because it should serve as a log of what I am doing concerning this endeavor, and maybe spark some support, some naysaying, some interesting discussions and some natter. At any rate, I hope to be able to contribute something good!

I am interested also. I was going to program for the iOS but can't bring myself to buy a MAC.
I have a lot of VB 6, VB.NET and Java - JSP development experience. My 10 year old daughter is a big gamer and wants to make games when she is older. I want to get her to help me make a small game so she can see what is involved in programming.
I still need to search for resources but if anyone has any good starter tutorials that would be great.
Sorry not trying to hijack your thread Logseman. Just don’t want to make more threads on the same topic.
Thanks

It's cool, in fact it'd be great if other people "out themselves" as potential programmers. It'd be a bit like a blog then, with the whole commenters sharing experiences . From what I've read your Java experience should make programming in Android quite easy, as the OS itself seems to be. I'm going to fire up my netbook and start the whole deployment. It can take the whole night easily...

After a whole night of downloads, I have deployed the SDK and eclipse on my netbook. They should make it more amenable, IMO, not only in this case but in installations in general. Installations are boring, as are videogame loading screens, but many of the latter feature something to make it worth your while.

I recently started android developing too (im 14 ) but since i was teaching myself it was hard to find a good book, but hello android by ed burnette easily teaches you how to make anything from 2D graphics to web views and 3D games. Tell me if you need a link, hope this helps

is that possible learn android programing without know any programing language before ?

Sure you can. At the end of the day you have to start somewhere. Why not Android ?

I have an EEPC netbook with Ubuntu Linux also. I think I will pull it out and see what I can do with it.
Does anyone think it would be good for this or should I use my HP windows laptop?
I hope we can get some feedback from some experienced Android Devs.

Well, I am happy to see people sparked by the same idea! I hope we all get to do something worthwhile!
Ncaissie, I'd recommend the Linux netbook. It's more portable, which is particularly important for your assistant if she wants to handle part of the process and I have to say, after instaling many Linux distros, I find Ubuntu 11.04 a perfectly stable, quick and efficient OS, much more than Windows or other Linux distros. I am in fact pleasantly surprised as I was unconvinced by Unity in 10.10. Aside of that, since you're programming in Android, which is a mixture of Java and Linux, it reduces the confusion if you work with a Linux host as well, in my opinion.
About the learning process, I've been reading a bit about Activities and Services and Android building blocks. I've decided on my first milestone: a "Hello XDA" app. If time allows, I will have it done before this weekend. If I can't post it after this weekend, I'll stall the project as it would be clear I am not focused enough.

have read good reviews for this book but I decided that I would learn Java before android since I'm planning on taking computer science anyway.

I was set to buy a cheapo Android phone as a development device. Turns out I made the worst choice: the Huawei U8110 Selina I chose seems to have issues about being recognised by ADB. Had I known this, I'd have taken some other one...

Fate conspires to keep me away from development Now my Xperia Play is not mounting the SDCards I feed it. I need to reflash it with FlashTool, but since I only had Linux installed on my computer and Flashtool requires Windows, I'm having to set up a dual boot environment, which implies wiping Linux, installing Windows and setting up two partitions, and then installing Linux again. Seriously, it's crap.

I really like this post,good luck with it.
Only one thing- I think it's important that you'd come with an idea for an app,rather than learning Android in general.
It will keep you motivated to move on and progress.

I've recently started developing for android too. While they get mildly bashed sometimes I've found that the apress books are pretty good. "Learn java for android development" by jeff friesen is long and very technical, and also requires that you be paying attention, but gets a pretty decent amount of java floating around inside your head before you even have to open up eclipse.
Honestly though I found it easier to work on a project and when I needed something that I didnt know to search around and find code snippets or dig through my books until I find the right answer and then move on to the next problem.
Good Luck

I do have an idea in mind, and it is related with the security pattern grid. Is that part of Android opensourced?

I wasn't able to pick up the pace this weekend But my goal is clear for now. I'm up for a Hello XDA app.

Well, here comes my very first apk... plus source (complying with XDA's rules ) I managed to screw some things because I typed the code incorrectly. Eclipse moaned in two lines until I discovered two syntax mistakes. Just therefore, because I saw them, I think I did the proper thing in typing this example code even if I had it in front of me. I will try not to copy-paste code if I can avoid it.
I've installed HelloXDA in my XPlay and it works as intended, and per the source you can see there's no malware in the app. And I know that I'm making a bit of a fuss about a stupid HelloWorld app, but hey, it's MY HelloWorld app, I coded it

I like this thread. I'm also going into android programmins as a noob still in highschool. I've got a question: I am looking into creating a home screen replacement app, so what do you reccomend me to do: Learn java first or just read through the sections of the android books I've purchased that talk about homescreens?

Start with something smaller than a homescreen. Mess around with some tutorials.

Thinking of getting into the Mobile Phone programming scene?

Hello All,
I am thinking of diving into the coding world for mobile phones and would greatly appreciate your thoughts.
As per experience I had a few programming classes in college and had no problems acing them.
Having said that I have had no further experience with programming. I am fairly comfortable with Visual Basic and C++.
With that which platform would you suggest is the easiest to get your foot at the door. From research I believe is Objective C for Apple, Java for Android, Silverlight for Windows 7 and Javascript for WebOS.
If it helps I did create my first "Hello World" app in WP7 following the eBook by Charles. ....I know nothing to brag about...hehe but atleast lets you guage my aptitude.
Fire away!

Anyone? Some wise words?

[Q] Coding Android Game - Where to Start?

Hello,
I would like to get into Android game development, mainly as a hobby, but given how obsessed I can get about hobbies I will not rule anything out! I have limited programming background (a bit of C, VBA, JavaScript...just the basics: variables, If/Else, For/While Loops, Arrays, functions, sub-routines etc..) but I tend to pick these things up fairly quickly....however I expect this to be a real long term project for me.
I have attempted to determine a sensible starting location and direction for a beginner to get started, but with so much information it really is a little overwhelming and I can't figure out what would be the most productive way to spend my time right now.
I gather that Android development requires Java knowledge, right? If yes, can anyone recommend any good websites/books with tutorials and code samples that can be used by someone who doesn't have an coding background already? To what sort level should I try to attain in Java before it's worth considering the Android specific side of development (I'm aware 'level' might be very hard to define!), or should I be thinking about these things in tandem from fairly early on?
If anyone has gone through a similar process, can you share your experiences? Pitfalls to avoid? Things not to overlook?
I have a couple of hours a night to dedicate to this for the foreseeable future, so any help filling that time efficiently would be much appreciated!
p.s. If there is a forum that is more suited to my question that I'm not aware of then please let me know!
Thanks!
Jess

I once wanted to become a droid developer too bro! I didn't get far though as I needed to focus on my day job more.
Anyway, what I did was learn about SDKs first. Just google it up, there are actually a lot of tutorials on the web. You'll need to be prepared to spend some money though for the SDKs.

you might get an idea here

Thanks for the advice, I noticed that google has it's own SDK, is it still worth investing in one of the other options?

Thanks for that. I've watched the first three so far, and have Eclipse & the SDK manager set up now. It was interesting to see that Android code is actually compiled twice, and given that the second stage doesn't have to be Java, it means that you can write the apps/games in something else, e.g. C.
Do you have any advice regarding which language would be the most sensible to code with? Apparently C is much faster for some things, so maybe it would make sense to dedicate myself to learning that rather than Java?

I don't know which would be best. All I can say is that I am learning java at the moment and hope to move on to android soon!!
Interesting to note Oracle are in court with Google at the moment in regards to copyright infringement. Android really is not a programming language , it's a mix of other languages....

I recommend this book...
http://goo.gl/APX0w
You can obviously get it at other places, and cheaper than that too, but it's a great book. It covers setting up Eclipse and the Android SDK and gets you going with lots of the major elements of both Java and Android together.
I rate it, but I rate Sams books in general. They've always been good.

[Q] about knowledge and jobs

Ok so I'm really interested in android development and I'm gonna get some books to read about them. Books that I'm gonna get are C and Java for general OS knowledge and to develop apps. So I'm wondering what jobs can I get in future??Apart from these:
-Working in Google[i made this an exception at the moment since its not easy to be the top]
-Making apps and sitting at home
-Making mobile apps for companies
Hope to get some good replies, cause I don't wanna choose the wrong path and have my life ruined/jobless in future
PS: Is android OS/kernel 100% on C only?? no C++ or C#? also are the apps 100% Java??thanks!

Learning Java and C++ isn't going to ruin your life even if it turns out to not be what you wanted. It takes like, a semester to get the basics down - this isn't four years of your life. You can even teach yourself.
Writing code is like writing English - most people can learn to do it. It's the creativity and ability to problem solve that makes a difference.
Just learn C++ or Java (flip a coin) and see if you like it and if it's a kind of thinking and problem solving you're good at or even like. It's not going to take ages. It's like taking a cooking class to see if you like it - you're not going to be a master chef or even a good one at first - but you won't know unless you try. And even spending a year and not wanting to go on isn't the end of the world.

Yes, Android Kernel is actually a modified Linux Kernel which is 100% written in C. No C++ or C# is involved. Android OS is written in C, C++, Java.
And yes, all the android apps are written in Java and there are places where XML editing is performed.

Jobs will be mainly based on your education and experience. Just do stuffs that proves your experience, add it to your Resume, and if employers are convinced you'll get the job. There are countless opportunities for Android development.
