I'm 17 years old. I'm a student at high-school.
I want to learn to program on Android and start making useful apps - I have some ideas I could implement, they're basic, but ingenious. The thing is I don't know where to start.
I know that to be able to program on Android, you have to understand Java. My only interaction with Java was about a year ago, when I had to make a bridge between 2 programs. I did it by imitating other's codes. So basically, I'm a newbie regarding Java.
This is my know-how:
C++ is my main language in which I program: I program around 4 hours a day. I make extensive use of OOP concepts, which is a very significant trait of C++. I've started programming C++ around 4-5 years ago.
I did a couple of projects, which involved micro-controllers.
I don't know if it helps, but I'm very good at building technical things in reality.
The question is: can somebody help me find a good way to learn to program in Android environment? Maybe someone who was in the same situation as mine. I'd prefer using only resources found on internet.
PS: The thing is, there's a contest in March about mobile applications, and I'd like to go there to learn something. First of all, I must have a project finished, so I can go there. Without this, I can't.

Start reading and following
http://developer.android.com/training/index.html?utm_content=bufferf56e9&utm_source=buffer&utm_medium=google&utm_campaign=Buffer
Secondly you can download and study some good books on Android Development after going through some basic apps.
Professional Android 4 Application Development: Edition 3 by Reto Meier is a very good book.
Finally start active participation in Android forums, Webinars and specially don't forget to test your apps on different Android devices.

What is the best reference to starting with Android?
Start in Android Developer website and get to know the basic API. You can also search in Youtube is a good source of hundreds if not thousands of tutorials relate to Android SDK.
What is the best IDE to developing Android and testing the Android
softwares?
You can use either Eclipse, a great IDE for java/android SDK, or the new Android Studio provided by google which I think is promising.
Beside the slow emulator provided by the SDK there is a good alternative and is GenyMotion.
Get Started Today -> SDK & First Video
Wish you the best of luck!

If you are new to Java, you should start with The Java Tutorials
After that, you are ready for the Android Tutorial.
Android also provides an IDE for developing apps, just in case the question will arise.
Good luck!

I'm an Android Developer with more than 7 years in the software industry. Right now I'm at a point where my knowledge is outdated and I'm looking for a way to get updated with all the recent changes and trends.
In addition to #NikosHidalgo comment, all I want to add is,
Just surround yourself with Android.
Not just in working hours but even out of it.
Subscribe to Android NewsLetters(Android Weekly).
Subscribe to Medium Android Community.
Subscribe to Android youtube channels( So that, as soon as you open Youtube you see Android feeds).
Follow Android Development pages on Instagram, Facebook, so that you are aware of what's new in Android, even in your free time.
Follow some of the top Android Developers/Consultants/Advocates on Twitter.
When you are doing non-coding tasks(Walking, Cleaning) hear out Android Podcasts.
Attend Android Meetups, great for building a network and learning
new stuff.
Join the Android group on Reddit.
Just make your whole environment include Android in it.
You have several options:
Answer other people's questions on stack overflow. Most of the time they are questions you will never ask yourself.
Try out the new android apis, and look for quirks... Android compatibility issues are a ... (no good word for it)
Look through google play at apps you did not develop, and try to figure out how they work (code wise)
Try writing automated tests for apps you did not write, to see how that works.

I read that they both are based in OpenGL ES 2 and both have Box2D physics.
I'm pretty new into Android game development, but somewhat experienced with game development (C++ and C#/XNA). I also have experience with Unity and Construct2.
So, I'm trying to find a great game engine to use to develop 2D games.
Do you guys have any recommendations or anything? I'm willing to purchase books and whatnot.
The difference is that LibGDX is a cross-platform framework.
You can basically write code just once and then deploy it with nearly no changes to desktop, Android, iOS, and even the browser via GWT/HTML 5. This is really convenient and will make debugging and developing in total a lot faster.
For more discussions like this see the following questions (make sure to read all answers and comments, since this is mostly an opinion based topic here).

Switching from AndEngine to libgdx - what to know?
https://gamedev.stackexchange.com/questions/43332/difference-between-libgdx-and-andengine
I am quite experienced with LibGDX and can definetely say it is a great framework with a really helpful and active community.
This question is not what SO is made for. Just to let you know, i think it will soon be closed.
Anyways: This 2 are 2 different engines. I am using Libgdx and have never used AndEngine. But i have read some discussions, so i list some of the differences:
AndEngine lets you start faster, Libgdx needs some setup and experience (IMHO)
Libgdx supports crossplatforming, meaning you can develop 99% on desktop and when you finished you can add a few codelines and it runs on Android to.
Libgdx is a bit more flexible and powerful, which is positiv and negativ (to flexible is overkill)
Libgdx has most times a better performance as much as i know.
Both have a 2D scenegraph and other possibilities to (low level ways)
Source: AndEngine vs Libgdx, the developer talk both about their engine.
Well AndEngineis a native library for Android platform.But LibGDX is a cross platform gaming library which can support all platforms.If you want to support your game to many platforms than use lidgdx.If you are targeting only for android then AndEngine is good Solutions.Both have to code in Java only.
If you are good at C++, i recommend you to go for Cocos2dX which is also a Cross platform gaming library supporting all platforms.check this link for cocos2dX

Hello guys I know there are obviously tutorials out there for learning java, but I was wondering is there any existing tutorials that are aimed at teaching you how to develop bukkit plugins via teaching you java in the same adventure!
This can be in form of a eBook, video or whatever.
You need to learn java before you try to make bukkit plugins. I tried making plugins before I learned java, and it was much harder than I expected. Read this, and get a basic understanding of java before you start. Also java books are a great resource. Once you learn java, Pogostick29Dev and SGTCaze (Youtube channels) are a perfect place to start making Bukkit plugins.
Here is how I learned to code Bukkit plugins (It would be very helpful if you had a basic understanding of things like loops and if statements in other languages)
To learn java, theres a nice YouTube tutorial by TheNewBoston. It is for beginners, I watched only the first 20 episodes.
Then, you could take a look at Bukkit's official plugin tutorial.
After that, you should just Google what you don't know, and use the Bukkit forums under Plugin Development or the Spigot forums under Plugin Development, as questions on Bukkit get more attention there then they do here. If you have only Java questions, or any other code-related questions, then this is definitely the place to go.
If you have no understanding in coding at ALL, I recommend you take a couple tutorials at CodeAcademy on JavaScript, as it's one of the most simple and easy to learn programing languages (in my opinion), and it's the first language I learned.
Just remember, though, JavaScript is a different thing than Java, so you obviously won't learn Java at CodeAcademy, yet, if you take the JavaScript tutorial, it will give you a basic understanding of things like if statements, for loops, while loops, and switch statements.
All tutorials i've seen for minecraft assume that you have some basic java skills. As most minecraft tutorials will only show you how to use the API, not how to write java code. So i would suggest to start with a basic java tutorial, and try to implement that into a minecraft plugin.
Once you get basic Java down, http://www.youtube.com/user/PogoStick29Dev has some pretty sweet tutorials.
You should take a look at bukkit's plugin tutorial at:
http://wiki.bukkit.org/Plugin_Tutorial
Almost everything you need is there!
Have you tried this?

It worked quite well for me!

I've been write window programs with C# + WPF for a while now. It is very good, has alot of rich elements as of .NET 4.5 but I dont really buy the idea of porting window based programs to other operating system like OS X using mono and others.
I started working on Java and Python, I haven't written any desktop based program with anyone of them yet as there are war of GUI framework/toolkit out there and everyone is just getting religious about things.
I need some clarification hence the following Questions, mind you these questions might be answered before but like I said, Clarifications:
What is the different between GUI toolkit and GUI framework
For Java programming, I see swing is integrated with Netbeans, from my research, people are speaking of qt's Jambi and GTK for java and python, I have no idea about any of these and I want to know, (1) Which do you use and why? (for Java and python), (2) Visual studio do all the magic for WPF and C#, which IDE can do these magic in java and python.
Lastly, I want you all to know that my asking these question is just to know which rich, powerful GUI and cross platform toolkit/framework (Whichever the right term is) is best for java and python with easy learning curve.
Constructive criticism are welcome BUT, I will be glad if there are answers.
JavaFX seems like a poor imitation of WPF.
Still, I have not seen any examples of how much (if at all) support does JavaFX provide for MVVM, which is what makes WPF the best UI Framework in the history of mankind.
from what I've seen, swing is more similar to winforms than anything else, if you come from WPF that will feel like going back to the stone age.
Side Note: java IDEs don't hold a candle compared to Visual Studio.
I know QT is for Java (and Python of course). It is well documented and is used by a lot of people around the world.

I am about to start new Android app considering that Java development is not my strongest side I'd like some advice on where to start. The question is not that much about Android API it's more about the right tools and code organisation.
Should I use template app like Android Bootstrap and are there any other better than that.
How should I organize my code so it makes sense while the app grow.
Any other libraries that might help?
The app would be for downloading music and it'd be free one. There would be a server API that will deliver the content.
In my opinion you should start with a blank project and try to learn Java and understand how the classes in Android work. Using a template is not the best way to learn programming because you can easily get confused and not understand what the code does.
You implement the classic 3-Tier architecture with packages for the Domain, Repository, Controller and User Interface. This way you can stay organized and easily improve on your app.
Read Android forums, documentation and see what libraries do you need to use.
Firstly get stronger on Java development, go through the Java SE tutorial. Then you can take a look at the Android Development Getting Started page.
I'd also recommend you to invest on some good programming book
