Will a Blackberry smartphone application written in the Java api work on the Playbook without modification?
According to RIM, once the JDE player is released, they will have to be re-packaged which may require re-compiling, to run on the PlayBook. The same applies to Android applications. In either case you will not be able to download native JDE or Android apps and run them on the PlayBook.
The only application SDK path that allows for BlackBerry Smartphone applications to run both on BBOS, Playbook and BlackBerry 10 is the HTML5 WebWorks SDK

You may also be interested in cloning bbUI.js, a free ui framework that works across BlackBerry devices going back to OS5. bbUI.js targets platform specific native features, like access to hardware apis, while providing a consistent feel.

Best of luck to you.
Yes, RIM has announced that they will release a virtual machine which will play your existing blackberry app. I'm not sure if developers have to re-submit their blackberry apps though.
Playbook will also support Android apps, but developers will have to recompile their apps and submit those to App World.

I want to know whether google is planning to support any other platforms other than iOS and Android for Cross platform development using Flutter.
Like React native windows for React native does flutter have framework that would support windows phone development?
Nobody can answer this question except Google, however it seems very unlikely that anyone would put effort into Windows Phone when even Microsoft are not:
Of course we'll continue to support the platform.. bug fixes, security updates, etc. But building new features/hw aren't the focus. 😟

As for:
support any other platforms other than iOS and Android for Cross platform development using Flutter
This is not officially supported, but lots of people in the community are interested in running Flutter on desktop and have been playing around with it. Maybe in future it'll cover more platforms even if they're not official or from Google.

A job we are doing right now has windows phone compatibility as a requirement.
My suggestion is to look into exporting Flutter to Web and then making a windows app which is just a full screen webview and loading the flutter web app in the app's internal webview.
I developed one application in Blackberry OS 6.I deployed that app in to Blackberry world successfully.But it is not working in Blackberry OS 10.I am getting following error:
Unsupported for this device
Please help me how to run application in OS 10.
Thanks in Advance.
OS10 is a completely different system. It no longer supports the BB6/7 Java environment. You will need to port your app to one of the new supported platforms:
http://developer.blackberry.com/develop/platform_choice/index.html
Cascades (c++ & qml)
Webworks
Android
Adobe Air
With WebWorks it is possible to run your application in both BlackBerry 6 and BlackBerry 10, you may need to make some changes to your code, but it is certainly possible and there are plenty of resources available.
You can start from here.
Specifically BlackBerry states:
Your BlackBerry WebWorks app can be targeted to run on a variety of
BlackBerry device models or ported to a different OS, such as iOS or
Android.
Developing your app with BlackBerry WebWorks gives you the flexibility
to target users of the latest BlackBerry devices and those who are
using older models. Depending on the OS you want to target, versions
of the BlackBerry WebWorks SDK available for:
BlackBerry 10
BlackBerry PlayBook
BlackBerry 7 and earlier
See here for a tutorial on creating an application which is able to work on old and new BB devices (Simple Hello World application).
A good article to look at can be found here, which explains some of the fundamentals and differences with webworks.
We have a couple of Blackberry apps and are now trying to prepare them for BB 10. These apps are made in Java via Eclipse and/or RIM IDE tool. However, when I went to https://developer.blackberry.com/platforms/bb10, I saw that there is no even a mention of Java SDK. Take a look at image below.
So how am I supposed to update Blackberry app to BB 10? Any ideas?
You have to decide what to do with your applications. If you have an Android version, one option is to repackage the APK to a BAR using the provided tool set so that it will run under the Android player. There are many good Android applications that provide an acceptable or even good user experience this way. Another option is to port your BlackBerry Java application to Android (if there is no existing Android version) then package the Android version for the player. This would also allow you to market the application to Android users. The final option is to port the BlackBerry Java applications to the Native SDK, Cascades, HTML5 or Adobe Air.
The best way forward depends on how tightly integrated into the BB10 system you want to be. While there are facilities provided in BB10 that are the equivalents to those is BlackBerry OS, there have been significant changes required to enable the improvements everyone wants to see on the new platform. If you see BB10 as a significant part of your future business then porting to Cascades would be very worth while.
I have to develop a BlackBerry application which runs on all the devices running blackberry OS 7.0 and earlier, and can run on BlackBerry 10 devices, too. How can I do that?
Is a WebWorks application able to support all the above platforms? If yes, there's no IDE for WebWorks development .. how shall I code for that?
WebWorks supports BlackBerry OS 5.0+, BlackBerry PlayBook OS, and BlackBerry 10.
Regarding HTML5 featuers, this is dependent on the OS version. For instance, BlackBerry OS 5.0 is a proprietary browser implementation and does not support Ajax requests. BlackBerry OS 6.0 is WebKit-based, but is an older version of the engine when compared to something like a BlackBerry 10 device. So you'll need to be mindful of which HTML(5) features and functionality are supported on the various platforms.
That being said, if you have a shared HTML5 "base", that can be (re)packaged with the WebWorks SDK for Smartphones (BBOS), Tablet OS SDK (PlayBook), and BB10 SDK. Each will create an application that runs in the respective environment: Java, AIR, Native.
If you start looking at WebWorks APIs (i.e. JavaScript APIs that tie down to the native layer for functionality beyond HTML5; BBM integration for one), then you will need to leverage the API docs to see which APIs can be used with which SDK. There may be differences in implementation, or even availability, of various APIs depending on your platform.
HTML5 provides the most common "base" for re-use, but you will still need to be mindful of each platform's limitations and differences.
There is no WebWorks IDE, you can use whichever IDE you like to create your HTML, JavaScript, and CSS resources. The SDK is then leveraged to "package" those resources into a BlackBerry application for the corresponding platforms.
The HTML5 BlackBerry Developer page should have all the information that you need to start creating WebWorks applications. As that page mentions, you can choose to target all of BB10, BB7, and the Playbook OS with WebWorks.
Webworks can target OS 7.0, Playbook and BB10. You just have to download the SDK for the version you want to deploy to. Be mindful that each platform has platform specific APIs that need to be managed if you use them (like using NFC in BB10, etc). This is actually the reason why there are multiple versions of the SDKs. Each SDK exposes native features of the given platform to HTML5.
As for Development. The easiest way to get started is to use Phonegap. Their documentation is pretty thorough and they have scripts that deploy things for you and manage your directory structure, Manage your pins, and keys, developer tokens, etc.
I need to decide whether to use phonegap to create a blackberry application. The lure of the app being deployable to various platforms is enticing however I need to know if it will be able to support Blackberry versions 6.0+. So far the website claims support for 5.0, and 6.0. There is a link at: PhoneGap Supported Versions that is meant to explain which ones are supported however one link doesn't work and another takes you to a dated stackoverflow thread. I get the same results from other searches.
My question is can phonegap support higher blackberry operating systems such as 7.0 and later developments by RIM? Also if stability in terms of not having to continuously modify the application for oncoming OSs was important, would it be better to use RIM's WebWorks SDK rather than PhoneGap?
If you are only going to target RIM phones then the WebWorks SDK is probably the best way to go. If you want to target other devices that run iOS and Android then you should look at PhoneGap.
We get really good involvement from RIM on PhoneGap. They did all the code to add Playbook support to PhoneGap and are currently involved in the unified JS project as well.
