the application of air cannot detect new extra camera

I made an office air - env. the problem is when I disconnected my usb camera and start the application of air. the application detects the cameras didn't exist with Camera.names.length = 2; and then I pluged an another usb camera and use the Camera.names.length to detect the new camera, but the result is always 2, not the camera 2 existed with the new added that the total is 3. then I close the application of air and start it again, this time, the camera.names.length is 3. Why? the application of air just cannot detect new extra camera? the only way that the air application can detect new extra camera is to restart the application?

Flash player air flow also does not detect camera added during execution. It can detect if you remove the camera while you were capturing images from the camera. You can try to scan for camera has a timer and see if it detects then.

There is also a not so documented flash.media.scanHardware () method, which should force a hardware scan. I have not used yet, so can't vouch for it.

    I see not the logic of the any of those things, but if one of them do things long enough that you are trying to create new accounts that works, you will know how in the future until a proper solution is found.

    (2) this directory has two subdirectories with a single file of each. Go into each directory and apply the following:
    (a) make a right click on the file, open the properties.

    (c) it will issue a message: "to continue, you must be an administrative user with permission to view this object's security properties. Would continue you? ». Click on the button continue.

    Hi Chandra,

    When you create your database, you this place in the application package or you use the applicationStorageDirectory?  I think that should work in the repository, it would be problematic if you're using a location such as your application directory (or any place under Program Files) because this would require elevated privileges.

  • After close app, turn to gray and the application app icon cannot launch again

    Hi, I have a problem with my app

    The problem is:

    After that I closed my app, app icon turn to gray and app does not start again.

    I have to restart device to launch the application again.

    Recently I have updated to the latest software update (version 10.0.9.1103)

    "application does not handle the message 'Quit' and was slayed.

  • The application starts automatically on detection of the tag when using the DetectionListener.

    In my application, I need to read NDEF records and launch the application if it is not open already. Earlier, I was using the NDEFMessageListener for the same and affecting the 'autoStart' true value. This did the job for me.

    Now, we must also get the UID of the tag whose value can only be extracted by using the DetectionListener. Now the problem is, when I join the DetectionListener, there is no property as "autoStart" provided. Even if I managed to get the app open somehow, when the tag is detected, the Blackberry Smart Tags application popup comes, even if my application is running and processing the tag information.

    I want to stop somehow the Blackberry Smart tags opening, when my application is not on the device.

    Currently, I achieve this by registering the NDEFMessageListener and the DetectionListener, but since the

    public void addNDEFMessageListener(NDEFMessageListener listener,
                                       int typeNameFormat,
                                       String recordType,
                                       boolean autoStart)
    

    method is obsolete in the OS 7.1, and since a listener registration should do the job, I wanted to find a way to do away with all NDEFMessageListener.

    That is right. To contact the label for information other than the payload NDEF presented via onNDEFMessageDetected (NDEFMessage msg) you will need the target returned by the method onTargetDetected(Target target) of the DetectionListener interface. You can then use either target.getProperties () to enumerate the list of properties associated with the target ( http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/io/nfc/readerwriter/Target.htm...) or use the target.getUri (), which can then be used to open a connection to the tag to read the data from, say, APDU via the tranceive() method.

  • Can use the application Adobe Air Stratus?

    I have already built a flash app 10 flex who use p2p functionality, and everything works currently with stratus. Now, I want my app to run on Adobe Air, but it seems that p2p back do not work for Air.

    I can connect to the server stratus in application of Air, but after that, when I try to use NetConnection.nearID, an error saying:

    «ReferenceError: Error #1069: nearID property not found on flash.net.NetConnection and there is no default value.»

    I tried flex sdk 3.2 and 3.4 and none of these works, after that, I tried to package the application and install it on Air 1.5.3 and Air 2.0 beta, the same error occurs.

    Does anyone know how to fix this? Thanks for the help.

    Hello

    Yes, Stratus works well with AIR.

    P2P and multicast.

    If it compiles without error, try the debugger and make sure the NetConnection is real.

    Were there any changes since the swf version?

    If it was only none then check that the only things that are different, as the xxx - app.xml to ensure it is not AIR 1.0 or something.

    Hi all

    My question, as you can see in the title of this post is, you can open the App world app of in an AIR application without using navigateToUrl, which allows the browser to open first with an empty window.  In my application, I have now a button that opens the App World my app page so that users can post comments, or buy the version complete, but it seems a bit slopply how it works when you use navigateToUrl.  Is there another method for opening the app in App World?

    Thank you for visiting the communities of Apple support.

    I understand that some application of health data is not followed.  Looks like you don't have a device such as an Apple Watch or similar tracker connected to your iPhone 6s.  You would need a type of source or fitness tracker to collect these data before it would show in these categories.

  • BlackBerry, Blackberry Q5 Q5: Verbal announcement of what is on the screen, can not close the applications by typing, cannot access settings

    Hello

    This mornign I had a surprise. For some reason the phone seems to freeze when I open facebook. I thought who would be corrected by restarting, but facebook would be available temporarily and then it would freeze. The same thing happened with everything I opened on the Q5.

    In the end, the phone seems to be put in place for people with a visual impairment. Whenever I touch the screen, and then even when I want to reconnect, there would be verbal instructions and descriptions of what is on the screen. For example, I received the instruction to slide up to open a session, and then whenever I touched one of minimized applications the phone would be such which program it is and what number it is out of the apps on screen.

    Is there a shortcut on how to disable this setting?

    Or what I can do to regain access?

    Thank you

    Hello

    From what you describe, it seems that somehow you have turned on the functions of "accessibility". Go to settings > accessibility and check all those involved to be sure of anything you want.

  • TENS of installation in the application directory--> cannot find directory RTE

    Hello

    I couldn't find an answer of fitting about my problem using search, so I'll try my luck by asking.

    First of all: I'm using Labwindows/CVI 8.5

    I created an installer for my application using the Distribution Kit Wizard. Under the tab drivers & components I chose only the 'standard Run-Time'.

    On the Advanced tab, I left the option "Install Labwindos/CVI Run-Time Engine in the application directory" unchecked.

    This installs and works fine at my PC clients.

    Now the problem:

    My client does not want that all files are installed in the Windows\System32 directory...

    So I checked the option "Install Labwindos/CVI Run-Time Engine in the application directory" and created a new installation routine.

    This installs fine and the cvirte folder is also be copied into the directory of the specified program and not Windows\System32... but now whenever my client tries to run the application, it gets called with the following messagebox:

    Cannot find the directory RTE:

    C:\Windows\system32\cvirte

    Which is actually very good, because I wanted to RTE must be installed in the folder of my program, but somehow my request is always pointed toward the search in system32.

    Is there a way to fix this without copying the RTE in Windows\System32 again?

    Given your explanation, I can understand why you see the error message. When you try to locate the resource (bin) and directories of fonts, DLL RTE search in the directory of the process that loaded, then in the system directory. As RTÉ is not installed in one of these locations (instead, it is installed in the same directory as your DLL file), we do not find the directory "RTE". There is nothing particularly wrong with what you're trying to do, except that we can't do well. I'll drop a request to fix this for a future version. In the meantime, you have a few options:

    1. let the RTE to install in the system directory, as it normally would.

    2. manually copy the directory cvirte of your repertoire of the DLL in the system directory.

    3. ask the client install your package DLL in its application directory. The target directory can be changed by the customer at the time of installation.

    I know these aren't the major options. I personally highly recommend the first option, despite protests from your customer. Is there a good reason that it is forbidden to use the system directory?
