[Q] Best SDK for cross platform development? - General Questions and Answers

I have some programming experience (mostly web design) but first plunge in smartphones and its about time.
XDA I searched but honestly couldnt find this topic. If anyone could point me in the right direction, or am wrong for even thinking about an SDK?
Its just a directory type app for people to find parks, some simple menu's. Professional looking with great transitions.
I would appreciate it greatly and hopefully in a year I can help someone out..

Hello 2U,
In this thread I'm referring to several SDK/ DTK. As far as I know there's no SDK for several Operating Systems. Though I could be wrong; leave a link here if you find one
Have fun programming,
Senax

Check corona sdk, gideros and moai sdk with lua programming.
---------- Post added at 05:24 PM ---------- Previous post was at 05:18 PM ----------
corona and gideros is easier, but moai is open source and free.

Gideros SDK
I use Gideros SDK came at him from Corona SDK, because in the past few functions supported in Corona. Now Corona is more common and with the same function, but back i have not become.
For example, my first game made ​​by Gideros: "Slug" on google play

Would be helpful if you also included the types of programs you were interested in working on.
Good idea
Its a good idea if we all freshers hook up together. wht you say? and after that we will get some experienced developer to lead us

For android always java is best(according to the arcticles i read) so obviously JAVA
I know an app I would pay for is one that could control the video functions of a PS3 with my phone. I would think it is possible since the the PS3 remote uses bluetooth, but I'm not a developer so it might not be possible.
I don't know if you've done this already but google provides all the sdk material on their android developers site. They also give instructions on how to get started using the sdk. Pretty much everything seems to be built on java. Have fun!
Google provides almost all the tutorials and instructions you could ever need to begin developing.

yea you should start at http://developer.android.com/index.html if you know java you should be good to go after reading and doing the tutorials
Thanks
I already read those things. Anyway thanks for your support and encouragment. and im now done with
->installed eclipse
->installed android sdk
->connected both eclipse and android sdk
-> now reading a book on how to develop android apps(in chapter 3 now)
All i need
-> some good friends(those who like to develop android apps,its okay if you are noobs)
->One experienced developer to guide me [this is optional ;-)]

HAHA...pretty much me too. Been debating about getting started for just over a year now. (Fireworks, Dreamweaver, Flash, Actionscript3, HTML, javascript, ~coldfusion, ~php, learning C#, can read VB, etc.)
Coming at this from a designing for training view. Been 15 yrs in technical training and looking to learn more. I got a few project ideas already and two things I really want...(which is what I am using for motivation)
As for the google tutorials...hello worlds really don't get you very far and I have looked out on web for other tuts. They all seem to have issues though...
Would appreciate feedback on the following....
-- This site/tut seems to 'assume' a whole lot and the program doesn't even work:
=== http://androidcore.com/android-programming-tutorials/182-fancy-listviews-part-one.html
(this one seems to not be showing any errors in SDK [it was first time, but not after restart] but it force closes in my emulator every time)
--This site/tut looked a bit more promising but is also has stuff that doesn't seem to work:
=== http://androidwizard.net/2010/05/create-a-context-menu-on-top-of-a-listview/
(no such thing as a OnPopulateContextMenuListener according to SDK and google site, switch(aItem.getId()) is not a supported method according to SDK, .getItem(menuInfo.position) cannot be resolved...all things a newb is at a loss to fix)
So...I am actually looking either for better tuts that get more in depth than hello world or someone from those sites that I can correspond with (as a trainer my OCD is really bothered by missing info in what look like the right kind of tut.)
Anyway...jenod...if you get some newbs together to work on stuff...I'd be interested.
Thanks for your feedback.. wil surely PM u if i get some(i mean developers)..
(why) does Android
Know what would be totally awesome? If someone like (why the lucky stiff) wrote something poigniant, beautiful and easy-to-follow to lead someone into Android app development! Something that reads almost like his Poigniant Guide to Ruby or like Chris Pine's Learn to Program.
Ya I have just started in android development. I have had many years of experience in all sorts of languages java, perl, python, c++, c#, and c. I also have a start on one project that would be great to have a group of people to work together with. I am very interested with this. Hope this works out, shoot me a PM if you want.
Hey guys!
awesome idea, i study informatics in second year now and iam just done with my JAVA lessons. Maybe i could help u, cuz i want to learn programming apps for andoid in my holiday too.
I also have an Idea for an app.
So PM me if u still need some help.
mfg X
Please PM if you would like to make a team, I too am interested and have multiple ideas for apps that can be made and released quickly
Thanks
I have to really thank you ppl for your piceless support.
Interested ppl you can PM me your Personal info(ur name,age,interests and wht u know).

PM'd, any suggestions for apps to make as our starting point?
Hey idk if you all have seen this yet, but it is worth checking out. Google has a free software developing tool in beta at the site http:// appinventor .googlelabs .com
The beta requires an invite much like google voice but it looks to have some potential.
(type the url into the internet, I had to add spaces because I cannot post urls yet)

It will not be as powerful as straight coding. It is meant to allow people to make little apps for themselves. One review I read even indicated that inventor apps will not be allowed in market.
(This is all early speculation, but hey it is what I read today as I went ahead and submitted my info for an invite...LOL)
Coming from Macromedia/Adobe...this would be kind of like Captivate is to Flash is to Actionscript. This would be Captivate...simple but simple.
Hey this sounds like a great idea, hope everything works out. We need take over apples app market!

Where to start?

I have experience with a lot of embedded devices and software and am interested in getting involved with Android modding. I'm just looking for some good documentation (if it exists) on the basics or even more advanced details. Are there any good resources that go over the architecture of Android and what have you?
I apologize if this is a repost or a common question, but I tried searching but couldn't find anything similar.

Too short. Huh. Well, me too.
Well looks like I'm just going to have to dive head first into the source code lol.
I've only just begun looking at android app development myself, but I can recommend looking at the android notepad tutorial (should be among the first hits on google). Ti's a very basic tutorial but at least it introduces you to some android concepts.
Other than that, there are a few books around that you could take a look at, and ofc the all-mighty internet has virtually endless resources.
Happy coding!
It's best to have a good working knowledge of the Linux operating system / command line as well as a good understanding of Java.
Start with http://developer.android.com or www.helloandroid.com to familiarize yourself with Android's structure.
From there, check out http://source.android.com to get more into the source code and Android framework.
Google gives you pretty much everything you need.

Hello fellow Newbie! (this is my first ever post on xda!)
If you go to hackaday website there is a four-part tutorial. Sorry I could not post links:
"To prevent spam to the forums, new users are not permitted to post outside links in their messages. All new user accounts will be verified by moderators before this restriction is removed."
Hope you enjoy these (if you find them), and find them useful! Also, keep an eye out for part 5!

I am a software/web developer and I have the Android SDK, Eclipse, Visual Studio 2008 and a number of other tools on my dev box. I love coding in C# but I can do Java and some other stuff too. I just got Eclipse (Helios) setup with the ADT plugin and I am messing around with the emulator. So this is basically what it used for testing/debugging etc. or is there something better? I have my first little app up and running in the VAD emulator. I found out that you need Eclipse 3.5 (not 3.6) and the JRE 1.6 for everything to be happy. Now where to go from here....

You can either use the Emulator or a physical device for debugging (granted the device has usb debugging enabled). I would just look over samples and try to make more complicated application from here, it seems like you have all the prep work done.
Ok here's a good one...when I use the keyboard in the emulator I get Japanese characters instead of English even though I have all the settings I can think of set to US English. Anyone know how to change that?

How to make an app?

I'm putting my theming project aside for now and get onto creating an app that I've always wanted to create that I do not see ANYWHERE in the market, forums, android websites, etc.
I've been reading and reading and reading different threads, instructions, etc. But no clue where to start. I've been reading on App Inventor but realized that it is very limited and I have my high doubts that App Inventor will not be able to achieve what I have in mind to make.
I've got the latest SDK and AVD Manager, JDK, Java, and have been using my emulator to test edited APKs. I'm pretty sure I'll be using my emulator to see how my app progress is coming along and see possible FCs and other issues and correct them as well as adding more to the app to make it even better.
But right now I'm stuck at where to begin here. Right when I was about to create this thread, I was making the name of the Title of this thread and was given threads relating to my title name and saw one thread that was sort of mentioning what I'm asking here.
I read the link provided in that thread ( http://developer.android.com/guide/topics/fundamentals.html ) and got some clues but just not enough to get me started here. I just need that push to get me going and eventually push it out to the market and make some money as a side project and learn from that and possibly make more useful apps. I cannot disclose my ideas here because then someone else (who has experience making apps) could take those ideas from me and go make it.
Is anyone willing to work with me here to get me started? I've helped countless people so it would be nice for a change for someone to help me out here.
There are so much Android development books on the market that I suggest to start with one of them. It's the best way to get some knowledge of the design principles used by the Android development framework.
Another method is to start with some examples found on the web. Just search for Android examples or something like that and you get tons of links
Another method is just to create something, get stuck and try to search for a solution (the most pragmatic method )
Yeah I know. That's why I'm constantly researching. I'm seeing some similarities between Java coding and building scripts in IRC (which I used to do, nothing big, just really small stuff). But my main problem is knowing what exactly are the main tools I need. I've had Eclipse for awhile but never used it. It has a lot of stuff in it and I get lost after a couple executions.
I'm just anxious to get started somewhere and get the momentum rolling for starters.
Could someone point me to a good book/ebook ? There are many out there but I'm sure that are some better than others...
If any french-speaker knows one in Voltaire's language, I'm in too. But English is fine...

Yeah, a good book (english) would be great. Can anyone recommend one?
You don't have to buy books but they do contain a lot more info in one book and would be better to have than trying to scour the internet and pull a bunch of infos together and try to put it together to understand step by step on how to get started and everything else.
Here's a link to a lot of android development books:
http://www.amazon.com/s/ref=nb_sb_s...pment&sprefix=android+application+development
Here's a link to some more info to getting started that is also useful:
http://developer.android.com/guide/basics/what-is-android.html
You may also need to get a Java coding book to help you put codes together properly and understand what each coding does, and tweaking them to work better.
Here's the link to Java coding for Android stuff for beginners:
http://www.amazon.com/s/ref=nb_sb_s...x=java+for+dummies&rh=n:283155,k:android+java
I just bought 2 books for Android application development and looking around for a good Java coding for beginners.

I think any java book will do, as long as it covers the principles of object oriented design and the data structures used by Java. You don't need any info about GUI programming in Java because that's all covered by the Android application framework.
The best Java books are the ones written by James Gosling et al, the designers of Java. But that may also be over the top for Android application development. Just some basic Java will do to get you started. The algorithms needed for basic apps aren't that complex.
App Inventor is a great tool to develop your android app. It simplifies the development and the editor is very intuitive.
Check out my blog on App Inventor and AppToMarket and a Workshop

[Q] !!! What's the Best Book to learn Android Development for beginners!!!

The subject says most of it really. I'm looking for a book that will teach me to develop for the Android market. A book for beginners. The kind of book with lessons, tasks, examples etc..
I'm a complete novice when it comes to Android Development, I've no understanding of the Java programming language at all and only minimal xml knowledge. However I am very good with computers and learn quick, I've got the time the patience and the motivation + (a Samsung Nexus S & a HTC Desire S).
I know it takes time and practise but its something I really want to learn and have plenty of time on my hands at the moment.
I've done webdesign so understand html, css, online shopping carts etc.. not that that's going to help me a lot.
Maybe I'll need a couple of books one for Java and another for Android please provide your thoughts on this.
Any suggestions maybe with links (if allowed) would be greatly appreciated.
Many thanks in advance.

Though I've no links to books which you could buy..
Android applications are written in Java (J2SE, not a pared-down Java Mobile/Micro (Java ME) as found on many low-end phones) using an open-source J2SE implementation based on Apache Harmony along with tons of Android-specific libraries for things like UI and handy third-party libraries for things like HTTP requests and JSON parsing. That Java code is compiled and then transformed into Android-specific files in a format called .dex, and runs on the phone in a highly optimized VM runtime called Dalvik. Luckily, you’ll almost never have to think about any of those pieces in between writing your code and running it on the phone, since the tools take care of them for you.
You’ll want a recent version (3.4 or 3.5) of the Eclipse IDE (Integrated Development Environment) for J2SE, the Android SDK, and the Eclipse ADT plugin to interface with those tools and provide project templates. Be sure to check out Google’s complete installation instructions for details.
Here are some other links to get you started;

I just started out and the android developer site is really awesome. I come here for regular roaming looking for answers.
They have a bunch of "real" tutorials that is a step by step building apps like a picture that you touch and it makes a noise, to this pic call app and etc.
I just started my first CS class and we are using "Java: How To Program" 8th. But I have researched these forums looking for the same question.
The most up to date forums that had recommended books:
Beginning Android, Head First and The Dummies Android Book. Although most of the stuff i read said the android site has pretty much everything you need to know and that books will help with getting to know the basics!
What about roms?
im going through a similar phase in my life with wanting to learn about Android and im downloading the ebooks to my rooted nook color now.. What would be the first few steps in just building a rom... im not interested as much in building programs... but i am a flashaholic.
The best book to learn about android development hasnt been published yet. I geuss thats just because you cant publish XDA Forums xD
Hopefully you're a pro by now, but if not, I picked up "Hello Android" today from Amazon, and it has received a lot of positive reviews.

From my perspective I knew nothing about Java/Android, but I had a couple other programming languages under my belt. Just jumping into tutorials really helped me more than any reading material. Also there are a ton of helpful stackoverflow posts related to android, so if you get stuck a quick google search will usually help you out
Tutorials are best
Books help, but i like tutorials because they are direct information with real cases

That's the way i took .
I knew C, SystemC, some bash and C++.
Started with the hello world tutorial and then i just dove in with an idea.
API documentation, StackOverflow and Google eventually got me where i wanted to be.
Then just repeat this process often enough with other ideas and will get comfortable with writing android apps.
But the android sdk is vast and i still find something cool and new everyday.
Also try #android-dev on freenode irc.
I took a couple of courses on C++, Java, and one in C. However, I really get lost when I look at how Android apps are developed. Also has anyone tried mobile development tools?

Devs: Point me in the right direction please?

I want to learn how to develop apps for Android/Linux
3D interface apps are what I am most interested in building.
I know it will be hard work but I need to know where to start.
If possible I would like to buy good video courses to take like TrainSignals or CBT Nuggets.
There's also this awesome open sourced 3D UI I would like to port to Android.

Lol I can't tell if you're trolling... but
start with 2 things:
* lightly hacking your android phone to get the hang of the little things like .apk's and the filesystem (it seems like you prolly already know this biz)
* and start playing with the Android SDK
You need the Android SDK before you can do pretty much anything... and try to stick to the Java language (otherwise you also need the NDK)
Eclipse sucks majorly as an IDE (you program with these), but at least google now has a premade sdk+eclipse kit that mostly works
you can start from scratch with programming courses but obviously as a network admin you will have a strong sense of programming without even realising it.
do some intro stuff like MyBringBack where they teach you XML and overlays etc and then go straight to advanced Java (hint: object-oriented) and then OpenGL (the 3D side of things).
edit: please hit thanks if this post was AT ALL helpful, as for some reason I can't really do anything useful in any other thread than here so it is very much appreciated
EDIT EDIT: waiting yet again for annoying 5-minute rule... and that's me done in this place for another while me thinks!

I don't concider it flame bate....but yet I use both
as for how to learn.
1) start reading code.....all you can.
2) Learn to use a debugger properly.....I CAN NOT STRESS THIS ENOUGH
3) Discover new and intristing ways to think.....I find that I an other devs that I know do not allways stop to look at the larger picture
4) prepare for some long time at the keyboard....and get some time away to.
wec
ps.....I have been doing this for to long
