Currently there is a flutter app and it needs to be protect from screenshot or recording
but when I search about this, there is no way to implement this in a official way
but it seems there are some tricks (like 60fps? I know the concept but I don`t know how to implement this)
you can see the black screen when record the video on Netflix also (they prevent in some ways)
how could I achieve this? thanks
there is a package called window manager which does just the thing that you are asking it restricts external apps from recording as well as does not allow screenshots to be taken
a detailed tutorial is given in this article.

How would I setup an AirPlay video & audio receiver for iOS (and then save the stream as a video file)?
I know that this goes against Apple's guidelines, this is not intended for AppStore distribution. I am fine using private APIs.
Note: I am using Pythonista (with objc_util), so, if possible, answers written in Python will be very helpful, although Swift/Objective-C is still greatly appreciated.
I assume you have this idea after the recent incredible (but short-lived) Vidyo app went on the App Store. I managed to snag a copy before it was taken down, but recreating this effect in Pythonista is certainly desirable.
You could start with the unofficial AirPlay specification, which describes how the AirPlay protocol works. Specifically, you want the section on Screen Mirroring. From this, you may be able to put together an AirPlay interface.
I don't think objc_util will be necessary for this, Python provides some pretty low-level networking modules.
From reading the spec, you'll need to set up a server. Flask probably can't handle it, Flask is likely too high-level. It looks like the AirPlay streaming stuff doesn't even stay within the realm of valid HTTP requests.
I suspect you'll have a lot of trouble with this. The AirPlay spec (especially screen mirroring) is pretty complicated. You'll need to let your server receive a H.264-encoded video livestream (this is the same format Apple uses to livestream its events), and you'll also need to set up a system for synchronizing your video based on data sent through a separate stream. On top of all this, you'll need to provide some endpoints that return data about your server.
I suppose it's entirely possible that Vidyo found some private APIs that make this easier. I don't see any clear reason why iOS would implement an AirPlay server somewhere, but it's not outside the realm of possibility. If this exists, I'm not aware of it. You'll have to do more research.
Good luck ;)
I have started developing a Blackberry App in which it requires to implement sign pad. I googled about this and got a link related to this. From this I am not able to view code through Abode Flash Player nor able to get other resource to implement sign pad.
I don't think you'll find a reliable library for this. If you can't find any, your best bet would be to create your own by listening and drawing on a canvas.
Check out this solution. It's likely not 100% complete, but its a start.
I am trying to capture the on-screen activity of my app as a video (one that I can save/upload to Youtube).
There are many others who want to do this. Although the answers are generally sparse, there's no in-depth explanation of how to do this or why it can't be done.
There's a paid (and possibly sketchy?) option here.
There's this related, but again, not totally clear SO answer about taking lots of screenshots: link.
There's a Smule app called MadPad HD that "records" the user's actions and stitches them together (but it doesn't actually capture the screen, it just stitches actions together). Here's the output of a stitching: link.
My questions are as follows:
Is capturing the video output of the screen and turning it into video actually possible?
If not, is taking lots of screenshots and turning them into video feasible (performance-wise)?
If 1 and 2 are not true, is this impossible because of device constraints or because Apple doesn't want it?
Thanks!
Perhaps you've already found an answer for this, but I thought I'd answer if anyone else is interested: with iOS 9 this will, of course, be possible through the new ReplayKit by Apple. But if you need it sooner (and with backwards compatibility) there are a couple of alternatives that I know of: Kamcord and Everyplay. Both lets your users record video and share through multiple channels, YouTube included. Both should be Sprite-Kit compatible and easily integrated (at least according to their websites!). Hope this helps!
I'm currently looking for a way to track user activity. I'm working on an IOS app using swift and i need stats of apps usage. basically I want to get-make a tracking of the used apps. Data like opened apps, start time and shut down time... I know that for get all stats, maybe is necessary run a backgroud service, but, this is another problem that i think to solve after. for now i want to know if it's posible, if there is some way to get stats for used apps. I know that the UIApplication class call the UIApplicationMain function when an app is launched. Maybe, from my app, there is a way for access this info?... Thanks, i have been a long time reading but really, i can't see some clear option.
If (as David has interpreted your question in the comments) you are trying to track usage of other apps that aren't yours, he's right; you can only track your own app's usage.
If you are needing to track events in your own app, there are a good number of analytic frameworks available to do exactly what you are needing to do.
Flurry is one I've used in the past with success, and is one of the more well know solutions. I've also utilized Google's analytics framework. Both are pretty straightforward to integrate into your app and to track the sort of fine grained events you are looking to capture. You can't go wrong with either one of those.
Here is a (slightly old) list of additional tracking/analytics options beyond Flurry and Google's offerings.

i am trying to develop sort of internet radio application,i dont have any ideas of how to approach it.I surfed a lot,but i cant identify information to lead me to the right direction.
While surfing i came to know abt, player that they use to access shoutcast broadcast on their BB?
I came to know abt this link
so guys any ideas,how can it be used for developing the application.So Hoping for some results
Taking a close look at the source code for the application you linked to is a great start in understanding how to do streaming audio on the BlackBerry. They implement a custom SourceStream and DataSource and use those to feed audio data from the network into a Player instance.
The best source for information is the BlackBerry Developer website. There, you can find guides such as the Audio and Video Playback guide, which goes over this in great detail including code samples.
