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 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

Use this Spinner Wheel library. It's based on Wheel Widget, but this is more in Holo style.

When I use accelerometer in my Android app, sometimes I have to low pass filter it; when I use compass, I have to do some calculations to find the azimuth; etcetera, etcetera. Does anyone know a good android library that would make it easy to use sensors, without coding such calculations by myself?
There is library a guy mentioned in DroidCon. Its called SensorFusion.
Haven't been able to locate the exact library , but here is a nice article briefing on what needs to be done to improve the readings recieved from various sensors.

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.
