Good starting points for blackberry widget development - blackberry

Which good resources for starting widget development for blackberry do you have?
Are there any tutorials that go further then a hello world? Advices on how to structure your app how to integrate second party java-script libraries something like this?
Sadly the rim documentation is nearly non existent.

This is an excellent blog with advanced concepts and tutorials:

And this site has a wonderful tutorial on creating a blackberry game that describes and exemplifies complex layout issues.

Add map with list to Form for mobile app?

This is a very basic question, but I have no idea how to be begin, so please bear with me.
I'm a C# software developer, so I'm very familiar with the VS IDE and with Windows and Web development. But I have never developed a mobile application.
With that said, I came up with an idea which is essentially a screen with a map and a bunch of pins, and a list that represents each pin. It will run in an iphone and android phone. It will look something like below.
I decided to develop it in Xamarin because 1) I've worked with VS for many years so I understand how it works, 2) I can develop one app in Xamarin that can run both in ios and android.
I understand that it may be a very basic question, but I have no idea where to start. I also have experience with development, so I don't want to go thru the Hello World example. Finally, I also have a full-time job, so my limited free time would be used to completing this particular app.
So my question is: where do I start?
First thing first. You should get yourself familiar with Mobile Development(app life cycle, patterns etc.) by creating few sample applications (since you stated you were developing in Visual Studio using c# before it should be quick procedure for you). You can find documentation and sample codes on official Xamarin site:
Xamarin Website
Next get yourself familiar with MVVM pattern and MVVM frameworks to write applications using modern patterns and modern practises. I personally recommend MVVMCross or MVVMFresh.
Data Binding from Official site
FreshMVVM with Samples
Then get yourself familiar with Xamarin.Forms maps. It's a nice library that allows you to use one code and share them across 2 platforms. Google Maps official apis are also good but they are platform specific.

Enjoy and welcome to the Dark Side ;)

How can I learn iOS Test

I use Xcode 7.2 to develop an app. Now I want to study to test iOS. I read the test introduction from https://developer.apple.com/library/prerelease/watchos/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/01-introduction.html#//apple_ref/doc/uid/TP40014132.
How can I learn more about XCTestCase?
You can find many tutorials over the internet.The following few tutorials may help you better understanding.

raywenderlich and cocoacontrols are the most usefull website to learn anything about iOS.

Beginning in Lua for Corona SDK

I have started working on Corona SDK.As you all know it uses Lua as the programming language,i wanted to know some good links or ebooks which i can refer to begin development.I am an iPhone developer and working on objective C since last 1 year.
Any suggestions,help would be appreciated.
Thanks
Aditya
I've been using this: Programming in Lua, first edition (FREE online edition of the book)
The Corona SDK forums are also good for specific issues related to the SDk itself. It seems it is having a few database problems just right now, but you might want to check it later.
Edit: just for completeness, here is the link to the Lua Bookstore # amazon (not an affiliate link).
You can also check out http://learningcorona.com/ which has a huge listing of tutorials for Corona.
Here's a great resource for learning Lua, it's aimed towards beginner programmers (doesn't sound like you), but it does a great job at introducing Lua and most of the basic concepts:
Lua for Beginners:
http://lua.gts-stolberg.de/en/index.php?uml=1
That, as well as the "Learning Corona" section of the Ansca docs should be plenty enough to get you up to speed in a very short amount of time:
http://developer.anscamobile.com/resources/docs/
TIP: Start working on a project, or converting an existing app using Corona and you'll learn it blazing fast! That's what I did, and I learned it quickly enough to have one of my games fully converted in about 8 days.
For understanding basics of CORONA SDK I will prefer "Corona.SDK.Mobile.Game.Development.Beginners.Guide"
book from Packtpub publication.
and You can also check out http://www.learningcorona.com/ for tutorial both video and audio.
The Lua Reference Manual is also an excellent read: Concise and complete.
Lua Gems is also worth looking at (at least the freely available snippets).
I found the Beginning Lua Programming book to be pretty good as a complete reference for Lua with good example code.
My very personal advice is just take a look at great books (Programming in LUA is covering everything) and switch as soon as possibles to samples / tutorials in order to learn all the API functions.
There are several Corona sdk video tutorials on YouTube. One demonstrates how to create a simple balloon game in a few minutes. You can have Your Lua editor in one window and YouTube in another, and click on the video to start/stop and switch to the editor and type in the code. Some tutorials provide links to download the code.
hello you can use their website they have good documentation you will find it here

BlackBerry Widgets in the wild?

I've been writing BlackBerry applications in Java and I'm interesting in developing widgets as well, but I'd like to have a look at a real world BlackBerry application implemented using the Widget API first. I find a lot of tutorials, code snippets and forum threads / stackoverflow questions regarding BlackBerry widgets, however I wasn't able to find a live widget that I can run on my BlackBerry (or maybe I just didn't realize it was a widget).
So, are there any (free) real world BlackBerry widgets I can try to learn the look and feel of BlackBerry widgets?
I finally stumbled over a small list of applications implemented as widgets:

Good tutorials for starting Palm WebOS development?

Recently I've been getting more and more into mobile development. I am currently working with the iPhone and Android based devices.
Palm's new WebOS looks interesting.
Are there any good online tutorials for quickly getting up to speed on developing for the Palm WebOS?
The Palm Developer Network has some basic overviews: http://developer.palm.com/
They also have a section up there: Palm webOS: Developing Applications in JavaScript Using the Palm Mojo Framework. This may be a good start.
Palm webOS: Developing Applications in JavaScript Using the Palm Mojo Framework is a book in the making, available currently through O'Reilly Rough Cuts program).
You can easily read the first chapter.
That's the closest you can get currently from official sources. Unless you apply to their SDK early access program (sdkapplication.palm.com/sdkapplication) and they let you in (you can apply for it until the SDK is officially released to the public).
Of course, another thing we can do until the SDK is out is catch up on whatever technologies we individually need that programming for Palm's webOS will require: JavaScript, HTML5, CSS... and there's ton of material about these online. Actually, there are many websites dedicated to Palm Pre and webOS that sprung up recently. The one that is more programming oriented that I know of is webOShelp.net: take a look at their Getting started with webOS guide (www.weboshelp.net/getting-started-with-webos).
P.S. sorry about not clickable links, had to play the system somehow ;) - it won't allow me to post more than one link since I'm new here.
Now that the device is out, people are actively playing with the device. Best site I have found so far is (no affiliation) http://predev.wikidot.com
Also, if you root the device, you can look at the source for the shipped apps in /usr/palm/applications
I have additional notes at http://friendfeed.com/
The site www.weboshelp.net has quite a few good tutorials.
This blog has a good tutorials:
