I am trying to profile my AIR app in Flex Builder.
The app is starting but not the profiler.
Is it actually possible to profile AIR apps in FlexBuilder?
Yes.
You may need to switch to the profiler view via the link in the top right of Builder.

Some cross-platform tools (like Xamarin native and RubyMotion) allow the development of two separate views for Android and iOS, while keeping the business logic shared for both of them. Others (like Apache Cordova or Xamarin.Forms) share both UI and business layer, with the option to use platform-specific overrides when necessary.
What is the state of the interpreted JavaScript frameworks (NativeScript, React Native or Appcelerator)? Are they all focused on creating single UI with platform overrides, or do they allow creating two separate views for each platform? For example, is it possible to create a view using Fragments in Android, but a different view on iOS (since Fragments do not exist there)?
Cordova uses WebView, that mean GUI level will be the same for both Android and iOS but different per Device version. In case of Android each client has own Chronium version and it can break UI behaviour. So developers use Crosswalk to set fixed Chronium version. (extra 20M to your application).
BTW Ionic that uses Cordova architecture uses native behaviour per platform. For example for Android Tabs located at the top, on iOS - at the bottom
On other hand Xamarin (C#), React-Native(JS) and NativeScript(JS) call native APIs. They don't use WebView but generate Native code.
For example if you create button - it will look different: on Android - material theme, on iOS - iPhone theme
Anyways, the bottom line is: everything depends on resources and time. If you want to build application fast, with the same view - I would go on Ionic2+ Angular2 + Cordova.
If you you have more time - go on React-Native or NativeScript (Still has poor documentation) or Xamarin (C#).
React-native's slogan is Learn once, write everywhere. So, you can choose what suits your needs, you can:
Share UI between platforms.
Share Only business logic.
So, the answer for react-native is yes. You can create separate UIs or you can share it.
Since you are writing components, one way of separating this logic is to write component.android.js and component.ios.js and the platform loads the appropriate one for you. Note that you can also do that programmatically.
You can see that in action in the official f8 app made by facebook using react-native
I want to create dynamic text changing icon like the calendar app in iOS 7 is there any way to do so?
You can not do this, there is no API allowing this.
Your apps icon is in your application bundle which is readonly and therefor can not be modified.
Sorry brother ... !! There is no API for your requirement. Apple does this only for their apps. Your app icon must be bundled with your application bundle.
I want to use the touch-enabled controls described in http://docs.oracle.com/javase/8/javafx/user-interface-tutorial/embed.htm. I'm building my application on a Windows 8 tablet, but the ScrollPanes are desktop-style, i.e. with scrollbars and no reaction to finger-dragging. How do I tell JavaFX that I'm on a mobile platform?
Edit: I just realized that the standard, desktop-style ScrollPane does react to finger-dragging, but it doesn't look like the example one in the link above.
Solution: the features can be enabled by setting -Dcom.sun.javafx.isEmbedded=true and -Dcom.sun.javafx.touch=true
There should not be a need to enable these capabilities, but JavaFX decides by itself if they are supported. You can query the capabilities programmatically, e.g. by PlatformImpl.isSupported(ConditionalFeature.INPUT_TOUCH).
I couldn't find this parameter in APNS options. Please add this functionality to admin console. For reference, description from your competitor:
content-available: (iOS only) If you are a writing a Newsstand app, or an app using the >Remote Notification Background Mode introduced in iOS7 (a.k.a. "Background Push"), set this >value to 1 to trigger a background download.
Thank in advance, although that option is missing, your servise is awesome.
This feature is under development, as I know it will be released in 1-2 weeks.
So, stay tuned with quickblox blog http://quickblox.com/blog/
It will available in Admin panel and through API as well
UPDATE
QuickBlox rolled out this update, check this feature in https://admin.quickblox.com
I'm building in FlashDevlop as pure AS3.
I'm looking at building a kiosk that uses two screens. Its used to administer tests. So one screen has the test, second the controls for admin the test. I have played with wide app but its not very elegant and I really would like both screens to run full screen on each screen. Is it possible to have one air app spawn two native air windows? A secondary question is it possible to detect multiple screens and target a screen to full screen to? Even something as simple as checking the window size to detect would work, im just not sure I can move and if the low level api will fullscreen on that screen. I could not find any examples of this in the docs.
What docs did you look into? I found it right away.
You'll need the Screen class if you want information on the screens that are connected to the PC. And here's some documentation on using it.
To create new windows, just instantiate a new NativeWindow class and call activate() on it when you're done configuring.
There's a lot of other useful stuff for you in the flash.display package. All the AIR stuff is marked with a little AIR icon. I have to admit that it would have been easier to find if they had put these classes in a separate AIR package.
