[Q] Developing Apps for Android - General Questions and Answers

Hello Guys,
I've been willing for a while to start developing for android .. I heard from many people that I need to know Java, that is OK since I'm a developer and Java was one of the courses I learned during college. But now, for android, I don't know from where to start, what tools to have
Are there any online tutorials to teach at least from where to start?
How can I create the APK file?
Finally, How to submit to the play store?
Thanks.

Google has a whole entire web-site devoted to this very topic that covers everything you're asking.

I tried, but failed to find good tutorials!!

Hmm, I think these all are nice tutorials:

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.

[Q] How to make an Android app?

Hello people
I've wanted to make a Android app for a while now but I don't know where to start.
Can someone give me some pointers on where to start.
If it involves coding then be warmed I'm a complete novice at that.
No coding method: search Google for Android app inventor.
Coding and better method: Android apps use JAVA. Take some basic online courses, then learn the Android sdk. (functions that are specific to android)
Option b is better, and if you have a little patience it won't be too hard.

If you want to get somewhere forget the app inventor and invest some time.
Start by using google on terms like "android tutorial" "android hello world".
Download eclipse and the android sdk (google has all the info and tutorial on how to do that).
The sdk has ALOT of very good example apps. From 3D drawing to system infos and interface layouts.
AAAAAAAAAAAAAAAHHHHHHHHHHHHHHHH Google app inventor is doing my head in.
if anyone is reading this on a scale from 1 to 10 how hard/complicated is making a app using coding?
Depends entirely on what you want the app to do unfortunately. If you can give some basic ideas of what you want it to do it will be easier to say how hard it will be.
well all id like my first app to do is when it starts up to show a picture with text then link you to a web page.
Nothing hard
Thats not too difficult, you could patch work something out of existing tutorials/example.
But its always relative saying how difficult something is.
It depends on the person...
Well sorry that's not helping much. I'm still at a loss on what to do.
Basically all you need to do is copy and paste the code from some tutorial examples, or you could even use the app inventor as you need barely any code to do this, for example:
http://developer.android.com/guide/topics/graphics/index.html
http://developer.android.com/guide/webapps/webview.html
Putting it all together and making it into an application shouldn't take you more than half an hour once you have gone through the starter tutorials to understand how and what it is you are using.
Ok I'll try that.

omg
i really wanna learn, so i went to purchase course and
DescriptionsAmount
Diploma in Java Programming.Diploma in Java Programming.
$1,695.00Item price: $1,695.00
$1,695
are you serious??
Well if you are really determined to learn it, you can manage doing it on your own too, with the help of free online resources. Search for a tutorial series on youtube. Here's one I had found useful when I was learning:
http://www.youtube.com/watch?v=Hl-zzrqQoSE
You should also buy a good book on Java programming and read it. That would help a lot too.
read android developers guide
You can check android developers official site it has lot of tutorials and resources.
You can go to next university library and borrow any Android book. It will not include the latest version of OS, but it will have lot of fundamental information in one place, written by one person. Tutorails often show you how to solve single problem only.
Thank you
Also great video
You're Welcome! Yes it is a great video. That guy really does explain it nicely.
Is App Inventor still working?
Look also at cornboyz tutorial on youtube. Same guy, slightly different tuts

Starting to develop

Hello, xdaDevelopers (Is it like that? Or XDADevelopers, or XdaDevelopers, well, doesn't matter, you can leave your opinion about that here, too.)!
I can see this is kinda a common thing around here, but, I really need the basics for programming, with a final goal of being able to make code for Android (from APKs to ROMs and such).
I just need people to point out good sources of learning, with a learning curve, please, that would be a great bonus in understanding what the heck I'm learning, from the basic of basic, to the goal here intended.
Maybe this is a bit too ambitious, but I pretend to be a professional programmer in the future, but I still have a kinda long way to college (3 years), and I wish I could start sooner that, it could even make my college life even simpler.
Well, I hope you leave your enlightenment in this thread. Thank you very much for any opinion given here.
*bump* Sorry. It was already in the second page. I just didn't want it to fall into oblivion.
Well your going to have to stsrt learnibg java if you want to make apps. Read some books. Also take a look at thenewboston channel on youtube.
Im learning myself. You just need to start and don't give up

I'm also posting (lazy way of subscribing to this post). I knew java, although it was long ago. I'd need a refresh on everything. And then, knowing java is not the only thing you need, as you also need to know how to develop for android itself. Up to date, which book would you guys consider the most easy to follow to learn easily to program?
Thank you!
Yes. I'm asking for links or books (preferably e-books) that could have all that information. I just hope I can become a great XDA developer.

+1 to this. i would also like to get into learning how to develop for android.
google has a lot of info on their developers page, it's probably one of the better places to start.
i don't know many other good websites or books though. anyone have suggestions?
If you want to develop Application on Android. You will need...
1.JDK (Java Development Kit), which includes the JRE. ( I use Java SE 7 )
2.Eclipse with the Android Development ( I use Eclipse Classic 3.7.1 )
3.Android Development tools ADT Plugin for Eclipse
( I use android-sdk_r13-windows.zip )
more detail http://androidcontrol.blogspot.com/2011/10/android-development.html
java for the user interface "pretty" part of the apps, but the real heavy-lifting guts of the app (where the real magic happens) will normally be written in c

I'm watching these. These are great. Starting with Java Development.

Share your experience about Android Development

If you are an Android Developer can you share your experience about android development? How do you start in Android? What is the first application you had done... thanks!
Greetings onebluemidnight,
You should learn how to program in java, their is great tutorials on the web and maybe on xda,
Then start off with the android hello world tutorial.
Good luck
This is mainly for games, but I highly recommend the framework Cocos2d-x. Made my first game for Android using it
Can't post any links but name is "Boomlings" on Google Play.
Edit: Granted the power of linking!

I don't have problem with java because i used java during my college which is 2 years ago and i am a PHP programmer now
I am using Eclipse with ADT plugin and the great moment for me is that it is like a cakephp (PHP MVC Framework) structure whereas it has a Model->View->Controller
and i am done also with hello world tutorial

Hi there,
I am not a big android developer, just wrote 2 simple apps so far. I started learning Java then read an android development book. It took me about 1-2 months for the whole thing. I basically make a simple java number guessing game (the system generates a number and the user tries to match it, higher or lower) and wanted to port it to Android. It turned out to be a little more complicated than I expected since Android was much more object driven than my previous experience taught me.
You can look up my app on the market here :
https://play.google.com/store/apps/details?id=com.danielsarfati.NumberGuessing
I found the "Hello World" app was much to basic to teach me anything, other than getting the whole SDK and dev environment up and running.

I am in no way a android developer yet im just learning stuff at the moment ... I referred newbostons tutorial its the best as said the hello world app doesn't teach your anything ..I think the best way to learn in go through and understand the source of code of the open source apps

What are the requirements to become a modder?

I am beginner and want to learn that how I can become android modder. So, I can mod android OS and apks?
It's just like being an interior designer. There isn't any requirements.
Just get your business cards printed and go for it!
So.. you're here just to advertise that site of yours?
Lame...

EDIT: Ok, now I see what type of modding you were talking about. XDA is not the place to request such knowledge, as it's basically the same as a warez request. The website you have in your signature, idk if you're part of this scam or not, but seriously, GTA 5 apk mod... this website is sooo sketchy. Please read the rules before posting.
Don't get me wrong, I'm disapproving the website, if you're not part of it, and just asked if you could learn how to mod an apk it's fine, it's just not at xda you should ask. But if you're part of this website advertising those fake apks that maybe used to hack someone's device, I think that's truly despicable.
I left my original answer down here:
Spoiler: ...
XDA is the place !
I personally don't know much java, and was unable to understand a word of english, so all of the tech documentation was a mystery for me. I just heard about one reverse engineering tool called apktool. So I set it up and started cracking open apks to understand how they really works from the inside by reading files and stuff. Then I came here (with a better knowledge of English and of what's an apk) and found many resources to learn. It depends on the kind of things you want to mod. If the UI is your priority, I'll advice you to start by understanding what's xml and how google uses it inside of every app. Eventually you'll have to learn java for more deeper tweaks, but to begin I think understanding how xml works is easier, and more practical since you'll have to modify that in order to change any UI element.
If you're after modding how the app works itself, then java is the first thing you should learn. (And don't learn any java, Android uses more the Java OOP).
I'll leave you some links for both ways of modding :
Modding UI (theming):
App resources overview | Android Developers
developer.android.com
I also did guide for theme using a simple method that doesn't require any prior knowledge of xml and stuff, and get you to play with the interface (like changing color and stuff):https://forum.xda-developers.com/t/guide-theming-how-to-theme-any-android-app.3777101/
Ticklefish is one good themer here on xda, he made some guides about theming that, even if they're old, can teach you a lot about xml : https://forum.xda-developers.com/general/xda-university/xml-101-xml-modding-easy-t2929816/
For the Java way:
I've seen many many java courses around the internet. Actually I can't tell you which one is the best or which one to avoid because I didn't learn java yet myself. Your on your own for that one, but good luck !
