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 ;)

We have a team that will create AE animations (including parallax, sound effects etc.) and I need to play those animations on Android as exactly they are, triggering them by swipe. For Android and AE first thing comes into mind is Lottie, that I've tried for small stuff. But what we need is more advanced and complex.
Only thing that I need to do is taking the AE animation and play them on Android.
Maybe it's possible with Unity, but as I've never worked with Unity, it's out of my knowledge how to do it.
Any kind of help is appreciated.
There is no way you can do complex animation on android using After Effects still you can go to Unity Documentation and search Android Animation to know more. Unity Documentation Android Animation
I'm asked to do an app with a 3D object mapped on a tag on the camera preview. The user should be able to rotate the 3D object on swipes, and to click on different area of the 3D object.
I'm investigating the different way to do it.
So far the best option I've found seems to be https://developer.vuforia.com/resources/sdk/unity, but I can't find whether it's possible to interact with the 3d model (rotate on swipe, define clickable areas).
Has anyone any experience with that?
I guess I can do it with some OpenGL, but I have no experience with it and it seems quite complex to start off with.
Is there any other library I should consider?
I would use OpenGL and start by the training tutorials on http://developer.android.com/training/graphics/opengl/index.html. Hope this helps! If you follow these tutorials you will be able to do what you want. ive tried unity and it is a really good engine too. and of course you can make an object clickable with unity! maybe using unity would be easier but the documentation on opengl is huge and is not that difficult to implement at least with first steps. hope this helps
The Metaio SDK can do all of that but I am not sure if it automatically provides the area of the model tapped, but you could ask here.
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.

I'm trying to find a good 2D graphics engine for a game... Something for a game like a top-down (slight angle so it looks 3D...) allowing the user to move around.. that sort of game...
Any help would be great, Thanks!
If I understand you it sounds like you want to make an "isometric" style 2D game. There's another question on stackoverflow that has a good answer as well.
As others have noted, AndEngine might be the way to go. Apparently it can load tile maps in Tiled Map Editor format (TMX), which offers support for isometric maps.
I recommend AndEngine.
They have an app demonstrating its ability on the market called AndEngineExamples.
http://www.andengine.org/
examples are available and you check out performance etc.. I know there are even some youtube videos specific to andengine
Andengine is great but it's resolutely 2D and you sound like you'd really like to do 3D.
An obvious alternative would be Unity - as it supports Android amongst it's many deployment platforms (and it's free!!)
I have search a lot for page flip effect in android. I found some links. An example for flip without using OpenGL.
But I want to implement a 3D real page flip effect for android. same as This Or the effect you have seen in IReader for android.
According to my search OpenGL must be use for this. I also search some framework that provide the alternative of OpenGL. But at the end I found nothing.
So I am just want to start OpenGL for this. But I have never ever use OpenGL.
Can any one help me for page flip? some useful link, tutorials, Starting up for OpenGL in android etc...
I am using this code. Its really really perfect for any one to understand and use. Thanks a lot to Harism
