I have a simple application that plays microphone - the code is taken from :
http://my.safaribooksonline.com/book/programming/android/9781449308001/exploring-the-apis/microphone#X2ludGVybmFsX0ZsYXNoUmVhZGVyP3htbGlkPTk3ODE0NDkzMDgwMDEvNDY=
This sample works fine on Ipad 2 but not on Ipad 1 (inconsistent behavior, sometimes plays a few seconds and breaks).
was anyone able to use the microphone on Ipad 1 (developed with flex 4.5.1), I need a very simple thing - record voice and play it
Thanks
Try increasing your buffer size for playback. This is located in the playSound function and in the example it is set to 8192 which should be more than enough. Try 16384 and see if that fixes it. Please note that this may make your playback seem to be delayed.
Are you compiling this application in Debug or Release mode to test? Sound playback is usually choppy in Debug mode and performs significantly better in Release.

On an actual apple watch you can change the system font size, just like you can on the iPhone itself.
In doing so it's hi lighted a bug with what I was doing trying to get a timer interface object displaying at a smaller than standard size. I'm trying to test this on the simulator though and unfortunately you cannot seem to access the system text size on there. The apple watch app on the iPhone in the simulator doesn't show anything, and the apple watch simulator itself obviously just shows a black screen when not showing your app.
Is this just something that you cannot test on the simulator at the moment?
Cheers
There are many things that don't work in the simulator (yet). For example speech input, correct synchronization of NSUserDefaults, etc. You may file a bug report for your problem.
I have a web audio player that uses Soundmanager2. Right now play/pause work on the lock screen and prev/next do not work. I worked on iOS 7 but I couldn't figure out why.
I see lots of talk about setting the track image and player controls in a native app, but not in an audio web app. That said I'd like to know why it quit working in iOS8 and what I can do to add a track image?
Update: Controls do not work in iOS 8, only on iOS7.
I found this on http://www.schillmania.com/projects/soundmanager2/doc/download/:
Side note: The prior release's pre-emptive fix for iOS 8 ended up being a non-issue, as the official iOS 8 release did not use "OS 10" in the user-agent string. Nonetheless, SoundManager2 will now correctly identify iOS 10+ vs. incorrectly flagging it as "iOS 1".
Since this question was asked Mar 21 '14 at 20:20, and the heading above it was
"version = "V2.97a.20150601"" (6/1/15), which means the update came after this question, and the edit, so
it should be able to work now.
How can you simulate a retina display (HiDPI mode) in Mac OS X 10.8 Mountain Lion on a non-retina display?
Search for, download, and install Apple's free Additional Tools for Xcode 8 (for previous Xcode releases search for Graphics Tools for Xcode according to your version).
Note: free Apple Developer account required.
Launch Quartz Debug application.
Go to menu: Window ---> UI Resolution.
Check Enable HiDPI display modes.
Quit Quartz Debug.
Open System Preferences.
Select Displays icon.
If using multiple display, select the configuration window on the display you wish to simulate HiDPI mode on.
Under Resolution:, select Scaled radio button.
Find a desired resolution postfixed with (HiDPI) and select it.
Your display is now running in HiDPI mode, simulating a retina display.
Source: High Resolution Guidelines for OS X
I found the following instructions. It seems to work, and it is much easier than the Quartz Debug approach.
"Enable HiDPI mode in Mountain Lion w/o Quartz Debug"
https://gist.github.com/3191869
In brief, run the following commands, log out, log on, and the HiDPI resolutions are available in the display preferences:
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES
sudo defaults delete /Library/Preferences/com.apple.windowserver DisplayResolutionDisabled
(In my case the first command was enough; the second command just prints an error message.)

For users trying to do this on El Capitan, please read the FAQ on SwitchRes's website. Also, if something's still not working after you did all the steps in the FAQ, consider uninstalling and reinstalling SwitchResX. That solved the issue I was having on one of my laptops.
Original:
After reading through several forums, websites, blogs.
I am here to present a solution for users with 15" MacBook Pro with Retina display connected to a Thunderbolt Display.
First of all,
Terminal command of modifying plist
Quartz Debug
Holding option and select "Scaled" in System Preferences
ResolutionTab (Mac App Store)
These methods DO NOT work for MBPr with Thunderbolt Display, for whatever reasons.
You will not see the HiDPI options to be selected.
The only tool I found that actually gives us the options is SwitchResX.
However another problem exists here.
Most users with this setup, I believe, are trying to use 1280x720 HiDPI because it's half the native resolution of the TBD.
According SwitchResX's FAQ, in some cases it is not possible to set to this resolution because of a bug within OS X itself.
Here's a screenshot for your reference:
After contacting the developer, he presented a workaround - adding one more pixel - which worked for me.
Install SwitchResX and open it from System Preferences.
Go to Thunderbolt Display tab, and add a Custom Resolutions with Scaled Resolution at 2562 x 1440
Here's a screenshot
Save using command + s. (or simply close the window and use the prompt up)
Restart the laptop.
Go to SwitchResX and select the new custom resolution in the Current Resolution tab. (Sometimes it doesn't show up right away, play around with it and it should.)
Here you go.
I hope this answer gets to users with this setup because it is really frustrating to use 16:10 resolution on a 16:9 display.
For those unable to enable HIDPI on rMBP or new MBA, I experienced the same on my rMBP 15" with Air Display. I solved the problem by installing SwitchResX. With the boolean setting enabled as shown in the referenced gist, the HIDPI setting shows up.
Dragging seems a little laggy in Air Display, but otherwise works great.
Try this
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool YES
[from here]
If your monitor supports it, it may also be worth setting the DisplayPort version to 1.1 instead of 1.2.
I have a late 2010 Mac Air with a Samsung S27D850 display and had all sorts of intermittent resolution switching issues until I made that change.
As for me its pretty good app that give you opportunity for changing resolution any that you want.
SwitchResX for Mac and MacBook.
This app resolved all my problems with resolution.
I would like to know if there is the possibility to set screen resolution when debugging web application.
For instance, I usually work with a 1600x900 screen size, but the customer requirement is fixed on 1024x768 resolution.
My desire is to start debugging in the browser setted to this resoluton, for the time of the debug.
Is it possibile ? Or there is some tool that allow this kind of behaviour ?
Thanks
You can try a browser plugin like https://addons.mozilla.org/en-US/firefox/addon/web-developer/ that will allow you to quickly change the resolution of the the browser your are debugging in. There's one for Chrome too (https://chrome.google.com/webstore/detail/idhfcdbheobinplaamokffboaccidbal) and I'm sure other browsers allow you to do this too.
This may not work automatically, but you can quickly switch back an forth between resolutions.
You can leverage the Windows API to try to set screen resolution from your program, if the DEBUG constant has been defined: http://dotnet.mvps.org/dotnet/faqs/?id=setscreenresolution&lang=en. However, if you have to terminate the debugger, your screen will remain set to the debug resolution. You also shouldn't release the "debug" configuration of your app without first commenting out the resolution change.
Usually, changing the screen res is something a desktop app should never do. However, it makes a certain amount of sense here, so just make sure the released builds don't do this.
Firefox offers a plug-in to test a website in different resolutions, but this is just testing it with one particular browser. http://www.makeuseof.com/tag/3-firefox-plugins-test-website-resolutions/
I have made a application that plays videos that are stored in a assets folder of the air application but when ever I run it on an hp slate the videos are really choppy. Is there a way to preload the video or does it have to do with the processing power? the videos are 1.72mb or smaller. They are flv format and they auto play when that application is started. I am using flash builder.
Thanks if advance for you help,
Justin
Since you are using Air, you also have the possibility of not using the fullscreen-mode. You can set the windowChrome attribute of the app.xml to none and the showStatusBar attribute of the WindowedApplication false. Then you just have scale the whole app manually to the screen resolution.
It's kinda ugly, but depending on your needs (e.g. kiosk-application) that'll be just fine.
