This one is fairly quick, but I am hopeful someone might be able to point me in the right direction.
I recently purchased an LG Wing and am trying to find some good resources that explain how exactly to develop an extended application that uses both screens at the same time.
So far I havent been able to find any decent resources, and honestly think I may be using all the wrong terminology.
If anyone has had a similar experience and could possibly share the content that they found helpful to get into this kind of mobile development it would be much appreciated!
Thank you!

I just decided today that I wanted to make a gallery app for my phone, pretty much just combine several features I like from different apps I've tried into one, perfect app, for me. The problem however is that although I know some java, took Programming 1 & 2 and currently taking AP Computer Science in high school, I have no idea where to begin. I roughly know and even less so understand the layout of Android Studio, but I can get by. I need help finding useful resources online to help me learn or even someone who is able to answer the probably many questions I have. I've watched some youtube videos and tried reading some tutorials but I haven't found anything that clears things up for me. I will ask a few questions now:
1.) I have no idea where to start or what to use to get the app to show images from device storage and micro sd card in a grid view. I have read things about using the RecyclerView to not use as much resources, and also something about Glide for better performance(I think thats what both those do, if I understand correctly) but I have no idea what to do with either or even how to use either.
2.) In the xml design portion I'm not good at navigating everything and understanding what I should use for what. I can make a good design in photoshop or other programs but I'm not sure how to actually take that vision and translate it into working pieces.
3.) Pretty much I just need help and will probably think of more questions as someone tries to answer those.
Thanks!
There are lots of good, free tutorials on the net. For example on the official Android Developer site: https://developer.android.com/training/index.html
- where you can find a lot of useful example code snippets, but there are other sites also - https://www.tutorialspoint.com/android/index.htm . It starts with the very basics and has lots of examples too.
Other non-free tutorials can be found at
udacity.com - Android Developer Nanodegree by Google
udemy.com
To reach data from your device storage or from your micro SD card you have to understand the principle working of content providers.
I do not recommend Recycle View, when you are a beginner, because it is a more complex thing than a List View (or Grid View). Start with these and then upgrade.
Glide is cool thing, because it saves you from a lot of useless coding and easy to use. On their GitHub page you find detailed instructions how to import it to your project - I recommend Gradle - and how to use it.
In my point of view, start reading one of the free sites patiently and than you are going to get answer for your questions, but it is very important to understand the basics.
I hope I helped! Sorry for my bad English, I used it a long time ago.
I'm trying to develop my own application, I'm not too bad with code (Java, Objectif C...) nor design (Photoshop, illustrator... ).
But I always have the same problem, I never know how to go from my app Sketch and Storyboard to defining my objects and classes in code. It just makes a huge mess in my head.
I tried looking around but all the sites I can find describe the processus as Having an idea, creating a design, a storyboard, coding your app, publishing and marketing. But none explain how to go from the said storybord to the code or architectures of your code, thus not solving my problem.
As time passes it gets more annoying, I feel stuck :/.
Can you help me with any leads ?
Pretty please with the sugar on top :)
Much insight and understanding can be gained from Apple Worldwide Developers Conference (WWDC) videos.

I want to achieve a nice 3D page curl animation in Android. I read some articles and found that nice effect can be achieved by OpenGL-ES so I started to learn OpenGL-ES (I did some of tutorials of OpenGL-ES and am still continuing) but I found it too complex for me to achieve this functionality. Also I got some examples which are available on StackOverflow and on the net, they work but I am not able to understand it, can someone guide me to achieve this functionality?
Based on the question comments I have an answer to this question.
YES, you can do that with OpenGL, BUT you need a deep understanding of math and graphics. This is a lot to learn, this will cost you at least a couple of weeks and it's definitely a hard path to go if you do it only because of this single animation (all of this applies if you don't take code which you probably won't understand and another human being put his whole effort into).
Nevertheless there might a ready to use implementation but unfortunately I can't present you one because I don't know if there's any out there.
Update
You callenged me, so I was eger to know whether there is something out there (because I saw that before and couldn't believe that there isn't a project out there which already does that for you).
And actually I found this question which seems to address the very same issue. And yes, there's someone who published his results here. And I have to admit: I looks awesome. It's also a pure java implementation.
But still: Having some background knowledge about OpenGL would enhance your whole attitude as developer. I'm not saying it's a must because not every one will succeed in OpenGL programming because it's quite hard to learn and implies a lot of math. But I think it's worth it because you will gain some deep understanding of current and all future graphical interfaces.
I apologise if this is the wrong place to ask this question, I did my best to make sure it has not been asked before and thorougly searched the web for any similar answer.
So here goes: I am having a very hard time finding any sort of reference, or better yet a tutorial on how to create a wallpaper pack for android.
To elaborate, I do not mean a live wallpaper of any kind. Just a pack of selected wallpapers packaged into an applications for distribution through the market. Ideally wih its own selection interface.
There are precedents on the market but for the life of me I cannot find any information.
Any ideas, opinions or suggestions? Maybe I'm going about this the wrong way?
Many thanks for the help!
Here is the GitHub repository for the wallpaper pack that CyanogenMod has. It should be pretty simple to base yours off of this.

Recently I was asked if I could help someone to get quick-started to android programming.
What would you suggest to tell this person?
Would you explain everything by hand or just refer to external links?
Which ressources would you recommend?
This whole issue should not take too much time...assuming 2-3 hours
Once my access to this issue was "Professional android application development".
Java basics are already preconditioned, so there's no need to explain ANYTHING.
For avoiding any misconceptions: This shall be just a quick start, no reference or something like this, so I just need some keywords and a hint how deeply go through it.
In my opinion, everything you really need is here: http://developer.android.com/index.html
All the downloads are easily accessible, the API reference is there, and the Dev guide is pretty well done.
This page has a getting started "Hello World" type tutorial that should work for your quick start: http://developer.android.com/guide/tutorials/hello-world.html
As far as your 2-3 hours goes. I would walk them through the hello world tutorial first as it gives a quick and dirty overview of the most important basics such as getting a project created and a virtual device up and running to test with. It will also start getting into installing and debugging.
That shouldn't take up all of your time so you may want to go into some basics of building a UI and concepts like Activities and Intents. Pointing out the API reference would be great at this point as well. I suspect that most of that 2-3 hours would be up if you get into any sort of detail on these.
Well you already mentioned a book in your question, so I would like to throw out http://commonsware.com/Android/ .
I've been working on an Android project for school, and I still have A LOT to learn, I dont think you can cover much in 2-3 hours. But anyway, with the above book, you can find an example that is similar to what your trying to accomplish(or go over), then look through the source code and what-not.
Aside from the Android Dev. website, the $40 collection of ebooks is the single best resource I have found to date other than Google searched or examples specific to my project.
Sorry if this doesnt really help your cause, but I figured it was worth pointing out.
