Is there any cheat sheet available for Android programming. Most commonly used classes with package description, just like a reference sheet would be nice.
For a concise list of Android recipes check out Damon Kohler's blog. He covers Intents, Wifi, Notifications, Alerts, Location, SMS, and Sensors in less than four pages.
I think this could be useful.
It's a brief summary, but could be interesting.
Here is a list of common tasks on the android platform, each has an explanation and typically an example.
I made this one based on my notes from getting started:

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.

By in-app tutorial I mean this
Do those in-app tutorials have special technical term to use, so it's possible to filter all those unrelated results?
How to implement them? Tried looking it up in Google, but obviously got keyword collision leading to unrelated results.
You can get some useful results with the search terms "android app onboarding".
Btw. extensive in-app tutorials are probably not a good idea, especially when they are mandatory.

I'm quite new to the Android world, and, due to work needs, I'm trying to get in.
Whilst I'm not particularly afraid of the "thinking" code (i.e. Java), I'm a bit confused when developing the user interface.
Since I found that the simplest yet most effective way to learn something is copying from those who are the best, I'm wondering if there's some resource or something, out there, well done.
I mean: do you know some open source app, from which I can build my own knowledge about Android layouts? I wasn't able to do it on my own, even though I wondered quite a lot!
1) A good summary on everything UI design in Android can be found here.
2) The best place to get started is directly from the official website.
And here are relevant examples that are considered as good design in Android.

Ok, i tried to give it a small go on my own, but just ran into too many problems.
Can someone help me implement this? Or point me somewhere. The bad news is I am looking for a complete instruction guide to this :/
I am implementing it into the google tabview tutorial, although i don't think it matters.
Thanks for help. This should be a good reference for people in the future.
I've used this tutorial here to setup shared preferences in my apps.

To actually view how the settings are created, check the tutorial but download the source and review I remember there are bits missing from the tutorial about how to get it running.

Does anyone have any dialogs that will allow a user to pick a number within a certain range? It seems like this would be a fairly common need, but I can't find a common dialog for it and I'd rather not have to spend the time creating my own.
Any help?
I know that more than two years passed but answer is still actual and I find some nice Number Pickers. Here is one of them
https://github.com/SimonVT/android-numberpicker
It's available in SDK since API 11 - http://developer.android.com/reference/android/widget/NumberPicker.html
I've just released some code that does just what you want. Check out my custom control, NumberPicker, which can be seen here: http://www.technologichron.net/?p=42
A bit late but for any that are interested, http://code.google.com/p/android-wheel/ is a good implementation.
Maybe useful:
