I was wondering how Android Live 3D wallpapers are created? what software is used? and how Developers make it interact with touch, swipe, etc... I hope someone help me how I can start ... Thanks
3d wallpapers are created in opengles. You can use libraries too . i am using Rajawali Library https://github.com/MasDennis/Rajawali . May be it will help u
Check out the Question/Answer live wallpaper with images
& for more about go to TheNewBostonAndroid for the Android video tutorials. Its very simple & easy to learn Android.

I have searched alot about creating a live wallpaper using opengl.In that I can only able to find the drawing shapes and rendering it.But I want to assign the objects (images) for rendering?Can anyone help me or guide me?
Where I can find the sample code?
Thanks in prior!!!
Maybe using a framework is a better way to create your wallpaper.
I know that libGdx allows to make live wallpaper. Drawing shapes and images is supported.
Here a tutorial for wallpapers creation:

And here the website of libGdx:

You will need this implementation of WallpaperService to create OpenGL ES live wallpapers: https://github.com/markfguerra/GLWallpaperService
I want to develop a Camera 2 kind of application. So i just wanted to know how to apply live effects to android Camera .Is there any android library for that? plz help me to solve the issue.
thanks in advance....
What have you tried? I assume by live effects you mean shown on the preview.
You can try what the answer here suggested, but any sort of complicated filter implemented in java is going to slow things down. For good performance you'll probably have to write some native code to process the previews. The good news is, if you're writing NDK code you can make use of libraries like OpenCV to do the filtering for you.
I have done apps which uses only pictures and sound clips. What I want to do is to build an Android app which involves animation. I have seen many of the "Water effect" apps in play store, which has quite good animation effect. One of my them is "Koi Pond". I would like to do the similar kind of app for sand. The detailing of the animation should look good as we see and touch the real sand.
I'm new to animation stuff and have no idea about it. Can anyone please help me out with how to use the detailed animation for Android? I know that it is not possible only with java. Please refer me to any blogs/docs available on this stuff.
Thanx
For such effects (as used in Koi Pond) you will need several pixel shaders. To use it you will need to us OpenGL ES 2.0. I would recommend using a game engine like AndEngine for the basic setup and the shader usage. If you have no experience with shaders it won't be that easy!
I'm not sure if AndEngine is the best choice for that, but it is possible with it.
Check it out http://www.andengine.org/
There are also a couple of shader tutorials in the forum
At first for translate or some other simple animation you can use android native animation method , but for great things you can use , this , I think it's all you want ;)

I am looking to create a 3D scene for Android devices.
I do not know where to begin, so help would be appreciated.
I, basically, need to create the 3d scene (what to use?) allow objects to be added or removed from the scene, and have an SDK to load and display the scene on an Android device.
I know all this would be ideal in a single resource, but I know I will have to adapt function calls to JNI/Android OpenGL.
Any help for how to get started or where to begin research would be appreciated.
PS. I will use a viewport to look into the scene from different perspectives.
Maybe you are looking for something more advanced but processing.org is a great place to start if you just want to use Java.
There is a Processing.org IDE for Android and you can use a plugin for eclipse.
There are a lot of great 3D modelling libraries that are easy and fun to use but also really good.
Here are a few links that may help if you think it's worth looking at.
One of many cool videos showing what you can do with processing.org
A less cool but interesting demo
Some libraries
