I'm a newbie in programming and is very much interested in knowing how to create my own Android Live Wallpaper. I know that a lot of resources are out there but they were pertaining to some advance level of knowledge.
Can anyone provide a "step by step" sprite animation to be implemented in Live Wallpaper? This by the way helped:
http://www.codeproject.com/Articles/140223/Create-a-live-aquarium-wallpaper-in-Android
but still when I try modifying it, adding random movements, different sprite size, the template was not that "friendly". Please I want to know it.
First download this live wallpaper template:
https://github.com/MasDennis/RajawaliWallpaperTemplate
Then go here to learn how to do the sprite animations in the renderer class:

Hope this helps you.

Anyone have idea how to create Meter like Measurement UI like this
When an activity creates, animation should occur in the meter and percentage/digit
will show..
Let me know if you know article or tutorial which explains how to do this. It will be much appreciated.
There are a number of projects that achieve this on GitHub.
Here is one I've found https://github.com/Todd-Davies/ProgressWheel
You should be able to do this with Path.addArc(). You just have to define the bounds of the enclosing rectangle, the start angle, and how many degrees to sweep.
Battery circle like Battery Widget Reborn

I need to the price range seekbar or slider like I have mentioned in the below image. Any help or sample code will be much appreciated.
Thanks in advance.
Android has no such a view. But you can create custom components based on your need. For your particular case, this one should be fine. For more complex scenario, you can refer this one on github.
You can find a nice simple android seek bar example in the below links. Ofcourse, you can modify the same to cater to your custom needs later.

I would like to implement an App for iOS, Android and Windows Phone where the user can control action with "face gestures":
When he smiles an image should be taken. When he is blinking an option screen should be shown. When he turns his head to the left, the left option should be chosen.
Is this possible for all three platforms? For iOS I think it should be possible with CIDetectorEyeBlink and CIDetectorSmile. But I still don't know if it is possible to detect head movements.
And I haven't any clue regarding the other platforms. Do you know any resources that could help me? It would be great if there are SDKs to solve my tasks for all three platforms.
I would suggest OpenCV library for such things.

I don't know how this is called but I guess you know what I mean by looking at the screenshot (there sometimes also is a finger pointing at the bright part of the screen).
Since this looks exactly like the little tutorial-like hint you get when you first install a new Android rom / start up a brand new Android phone: is there a standardized way or library or whatever for this?
Yes, this is library. Check it out: Showcase View library

I have been looking around for a good Android AR toolkit to play with. I have found a few references but I am not really sure which ones to try. It seems to be a lot of work just to get any demo's working.
My requirement is that I want to be able to detect AR Markers/Tags. I would then look to add a 3D model based on the orientation of the marker/tag. A nice basic cube would be a great start :D
So do any of you have any recommendations?
I have just tried http://code.google.com/p/andar/ and it is not too bad. I would really like one that has some better project examples and well documented source code.
Oh, and as this is currently only for playing with I don't want to be paying any money for it.
You can try looking at NyARToolkit
