• BB Torch - Dialog.doModal (disabiling FileSystemJournalListener reminder)?

  In our application, we display a unique dialogue (for most of the instructions) before launch us the camera application. However, when the user types a picture on the BlackBerry Torch 9800, our class FileSystemJournalListener does not fileJournalChanged() at all, even if we record the reminder with our Application object. However, when the user closes the camera and re - open it via the same method (where the dialog box does not display once again), the callback works very well. That's what I have so far:

  //within my UI container's constructor that launches the camera
  
  myImageListener = new QRCapturedJournalListener(this); //Implements FileSystemJournalListener
  
  ...
  
  //within my fieldChanged method in my UI container when the user clicks on the field that launches the cameraif(permissionCheck()){  if(myPersistDataObj.showHelp()){ Dialog d = new Dialog(Dialog.D_OK ,STR.INSTRUCTION,Dialog.D_OK, Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION),FIELD_HCENTER | FIELD_VCENTER);d.setFont(Fonts.getFont(6));d.doModal()myPersistantDataObj.shownHelp(true);showExternalCamera();   }} else {//notify user permission was denied}
  
  ...
  
  private void startExternalCamera(){            myAppIns.addFileSystemJournalListener(imageListener);     Camera.getInstance().invoke(); // start camera. Wrapper function that invokes the camera app}...
  
  //Invoke function in Camerainvoke(){   Invoke.invokeApplication(Invoke.APP_TYPE_CAMERA, new CameraArguments());}
  

  If the dialog box is a bit conflicted with my PopupScreen, that shows my user interface, saving my reminder, which not is defined before the opening of the camera?

  Looks like I was wrong completely.

  Even if he entered my FileSystemJournalListener class, it was indeed to call fileJournalChanged after all. Part of the problem was that for some reason, when OS 6.0.0 calls the camera, there is some cases where she would call fileJournalChanged and send JPEGs of no return paths (during initialization on the Simulator for the first time, he sent back/store/home/user/camera /), in which my reminder in my UN-registed PopupScreen my FileSystemJournalListener without validating that the incoming path contained a JPEG file.

  Now, he's going only to unregister the listener if we indeed have a way with a JPEG file and then process it. I'm just curious to know if this is expected behavior go ahead with OS 6.0.0 since this never happened with the previous OS versions? I just want to be sure that it makes sense to unregister it if I only want to deal with the last image captured by the user via the camera.

• FileSystemJournalListener and incoming SMS do not work together

  I need the two lisnner in my incoming sms app and added file listner

  Please help and sorry for the bad English

  You put the interface of the camera in a Thread, and not the SMS interface.

• FileSystemJournalListener; am I crazy or what?

  Pretty well dug in the demo, I can't get this type of work. The order of events (I think?) is supposed to be:

  (1) manufacturer of the screen load.

  (2) class form has a private member of the FileExplorerDemoJournalListener class that implements FileSystemJournalListener.

  (3) FileExplorerDemoJournalListener class has a constructor that takes the screen as an argument and keeps her in a private variable.

  (4) screen class going in the background (or otherwise remains active), and if the FileExplorerDemoJournalListener class lives to watch the file system.

  Don't know what Miss me, but I should get of the journal entries of this, and I get nothing.

• Example of FileSystemJournalListener HELP

  Hi, I am new, I am developing a bb application, which must not know when a picture has been added to the system either taken by the camera is received through bbm surveys.

  I tried this code:

  http://docs.BlackBerry.com/en/developers/deliverables/11942/Detect_when_img_is_added_or_removed_file...

  but there is a variable msg, I don't know where it comes from. Can someone help me with this.

  I would like to see a better example of this.

  I removed this part (msg is nothing) and it works, but it seems to be calling the FILE. Case ADDED more than 1 time.

  Thanks for the help.

  The code in this doc looks like this one is removed the FileExplorerDemo, which is a sample that you should have with your tools.  Look at this code for more information and maybe the answer to your question.

• While using camera in my current screen close request

  Hello

  I'm creating an application to send the form camera Images and gallary,

  (1) if I press the camera button in my application I want to capture image and show that image to the current screen.

  currenltly 2) I use below functioin to do, but the first use of the user application is invited to give permission to use the camera after that if we allow so the current screen is closed. before that it is capturing the picture.

  (3) if the use the application even after leaving the second time there is no closure of the current screen and it works fine.

• Removal of Documents after the Invocation is complete.

  Hi again!

  I need to show all kinds of Documents, since it would takes years to develop a full office suite, I thought it would be great to do just the same thing I do on Android and rely solely on existing applications to manage this problem. Unfortunately, I have to create the file on the SD card, because Connector.open("file:///Store/home/user/") always up a filesystem 1003 error, and I have my first choice which was invocation.setData (someContentToDisplay) and invocation.setType (someMimeType) will open DocsToGo, who will say in turn that the file is not found. "

  Now, all this isn't so bad, if I could just delete the file that has been written on the SD card immediately after that DocsToGo is closed or loses the focus, or better yet, after DocsToGo loaded the file in the memory RAM.

  My current implementation looks like this, the funny is that no exception is thrown, the deleted file is not:

  Doc DocumentEntity is DatabaseHandler.getInstance () .getDecisionDocument (docId);.
  Path String = "file:///SDCard/mobdec/";
  FileConnection fc = (FileConnection) Connector.open (path, Connector.READ_WRITE);
  If (! fc.exists ()) {}
  FC.mkdir ();
  }
  FC. Close();
  String filename = path + doc.getTitle ();
  FC = (FileConnection) Connector.open (filename, Connector.READ_WRITE);
  If (! fc.exists ()) {}
  FC. Create();
  }
  DataOutputStream back = fc.openDataOutputStream ();
  back. Write (doc.getContent ());
  back. Flush();
  back. Close();

  Create the call request.
  Invocation of the invocation = new Invocation (filename);
  invocation.setAction (ContentHandler.ACTION_OPEN);
  invocation.setResponseRequired (false);
  Use the registry to make the call.
  The Registry = Registry.getRegistry ("net.mobiledecision.client.blackberry.MobileDecisionScreen");
  Registry.Invoke (invocation);

  While (invocation.getStatus ()! = Invocation.OK & invocation.getStatus ()! = Invocation.ERROR & invocation.getStatus ()! = Invocation.CANCELLED) {}
  synchronized (THIS) {}
  Wait (50);
  }
  }

  FC. Delete();
  FC. Close();

  Thank you!

  It is not a concept of a 'House' in BBOS directory.

  Regarding your problem, you will not like the options that I will propose:

  (a) have a thread looking for active applications.  If DocsToGo is not active, you can delete the file

  (b) use a FileSystemJournalListener a DMoniteur activity against your file.  When it is closed, delete it.

  Sorry, I can't think of something better.

• Cannot call ESC key two times of the key event

  Hello, this is my second post here...

  lately im trying to call the camera application via:

  and when the user to take a photo, then the application will grab the location of the file and close the camera application. but when I try to close the camera application using:

  Inject the EventInjector.KeyEvent = new EventInjector.KeyEvent (EventInjector.KeyEvent.KEY_DOWN, Characters.ESCAPE, 0);
  Inject.post ();

  Inject.post ();

  Simply call the inject.post () once and jump down (when I tried it on a simulator its works well but when I tried it on gemini 8520 is not working as the Simulator). I put the inject.post () at the end of my FileSystemJournalListener class.

  is there anyone who can help me please, thank you

• How to keep track of a file?

  I want to follow the change of a file on the SD card. For example, when the "file:///SDCard/tempfile" file is modified, my program wants to receive a notification in this regard. How could I write the program? Or what API should I use?

  PS:

  1. If possible, I don't want to use a loop forever as «while (...)» {...}".

  2. the FileSystemListener interface can only monitor the status changed from roots. I want a similaer to interface with it, but can monitor common files.

  Please help me. Thank you!

  I wrote a class to set up FileSystemJournalListener Interface and added using addFileSystemJournalListener().

  Implementation of fileJournalChanged() can monitor the changes of one or more files specified using FileSystemJournal.getEntry (FileSystemJournal.getNextUSN () - 1).

  Thank you! This is what I want.

• Change the example of the camera to activate Flash

  Is there a way to turn on the flash on the camera as an example?  I would like the flash or light from the video camera to be activated when the Application starts.  I read some posts that say it is not possible now, but those who were a year ago or more.

  Thank you

  Do you mean to incorporate the camera application in your application? If this is the case, then not to my knowledge. Then, you will need to do the way it is done in the example of the camera and build all the features you need in your user interface.

  However, you can launch the native camera for aid which is available for 4.2 +:

  Invoke.invokeApplication (Invoke.APP_TYPE_CAMERA, new CameraArguments());

  And if you are for example answering a picture taken so that you can ask the user to return to your application, you can use the FileSystemJournalListener to be notified of any changes (adding file to take a photo).

• CameraDemo Bug in OS 6.0? Menu to delete the image

  I tried to integrate the camera into an application and effect of unusual screen in OS 6.0.

  I tested on 9780 and 9800 simulators and devices.

  When the field of viewfinder on the screen, everything is OK.  However, as soon as you press on the menu (for example to change the encoding), the s screen allowed.

  The attached images show that on a simulator of 9780.

  Has anyone seen something like this?  Any suggestions that workarounds?

  I will try to replace the menu with a PopupScreen and see if that helps.

  Fix.

  Use FileSystemJournalListener to detect that the photo was taken, get the path of the image.

  At this point, you have several options depending on whether you want to just take a single or multiple image.

  I seek only to a single capture so as soon as I get the picture, I force the camera app to close by injecting Escape keydown events.  This will also bring your application in the foreground.

  Generally, it takes about 1-2 seconds to take a picture of back in your application.   You get also all the advantages of the native camera application.

• Status of bad jpeg JPGDEC 23

  I have an application that calls the camera uses a FileSystemJournalListener to retrieve the recently taken picture and adds a thumbnail of that picture on the screen of the application that triggered the invocation.

  This all works fine.

  However, on occasion (and I can't determine exactly when or how) debug display "JPGDEC jpeg bad state 23.

  I don't know what this means, but it causes the recovered image to show that almost half of the sticker after calling createBitmapFromBytes.

  It seems to happen only with certain images or images taken by the camera.

  Any suggestions for what it is?

  It turns out that the combined Thread to check if the image is taken was great solved the problem. The Bitmap.creatBitmapFromBytes () was throwing an OutOfMemoryException. The user has been taking photos in the Large (2048 x 1068) resolution. I solved the problem by checking the length of bytes defining a scale for the thumbnail. Thanks for the help.

• Camera to call and wait for the photo?

  Hello world

  First post on these forums, but I've been lurking here for a while. I have a simple question that can have a simple answer, and I hope someone here can enlighten us on this issue.

  I'm looking to call the camera of my application, I can do it quite easily. In addition, I have a listener of filesystem implemented seeking a .jpg file saved after that the user takes a photo. Here are the relevant lines of code (more or less):

  Listener = new FileSystemJournalListener() {}

  public void fileJournalChanged() {}

  Long USN = FileSystemJournal.getNextUSN ();

  for (long I = USN - 1; i > = lastUSN; i--) {}

  Entry FileSystemJournalEntry = FileSystemJournal.getEntry (i);

  If (input! = null) {}

  If (entry.getEvent () == FileSystemJournalEntry.FILE_ADDED: entry.getEvent () == FileSystemJournalEntry.FILE_CHANGED: entry.getEvent () == FileSystemJournalEntry.FILE_RENAMED) {}

  If (entry.getPath () .indexOf (".jpg")! = - 1) {}

  lastUSN = USN;

  photoPath = entry.getPath ();

  }

  }

  }

  }

  lastUSN = USN;

  }

  }

  UiApplication.getUiApplication () .addFileSystemJournalListener (listener);

  Invoke.invokeApplication (Invoke.APP_TYPE_CAMERA, new CameraArguments());

  My problem is I want to access and extract the image from the camera in a way series application, then I would like my request for locking/blocking/wait until what the auditor has identified a new image file. I believe that this is possible, but I'm not familiar with how to do it. In my debugging experience, at least on the Simulator, invokeApplication is threaded (asynchronous) and my request is still ongoing in the background, even if the camera application is active and on the foreground. I tried to add a dummy while loop after the call to Invoke that checks whether my application is in the foreground (using isForeground) but has not lead me on the path.

  I'm working with JDE 4.6.1 and 4.7. Any help would be greatly appreciated!

  Best,

  Hi Peter,.

  Thanks again for your response. I'm really not in one of the videos/images . You can always check my github profile (www.github.com/filmaj), which also contains my range of PhoneGap - it contains the latest code of BlackBerry for our project. In addition, PhoneGap is completely open source and under license by virtue of the MIT, which is pretty liberal, so feel free to grab the code and play with it / use it at your leisure!

  Thanks for the info on the thread of events, which is very insightful. And Yes, almost all PhoneGap runs on the event Thread (except for the recovery of the resource - two resources the application external or local-unit, i.e. the pages html, css, js, images, etc.). It is indeed a difficult situation, but I think I have the solution, but it does not actually the code Java of BlackBerry. I think I can actually solve this problem as soon as the end of JavaScript.

  For context, here's a brief overview / example of how PhoneGap works on a BlackBerry:

  1. developer making an app with PhoneGap called something like navigator.camera.getPicture (success, failure) of JavaScript on the access to its Web site, with the 'success' and 'failure' based on the handles to reminders for image retrieval success or failure, respectively.

  2 some PhoneGap JavaScript wrapper code sets a cookie (document.cookie = "foobar"-call with a particular PhoneGap message format, in this case for the camera.)

  3. We then carry on native code of BlackBerry. Object BrowserField, that displays web application pages and executes the JavaScript Shell, then intercepts this cookie-setting event (via the eventOccured to the RenderingApplication method and Event.EVENT_SET_HTTP_COOKIE event type) and numbers which native device to recover/call feature.

  4. the specific device feature is called and returns a string from a combination of code JavaScript logic and JSON (code object for data transport representation). This string is stored in a Java vector, which is a member of class PhoneGap.

  5. at this point, the cookie-setting event method has finished running, execution returns to the wrapper of PhoneGap JavaScript function. Now, we get the contents of JS document.cookie. As done previously, using the same approach, catch us the event "getCookie" and fill it with the contents of the Java vector we populated earlier. It finally passed into the web page's JavaScript.

  6 back in the land of JavaScript, the last step is to eval() the contents of the cookie, fill data members and call reminders on the right.

  So my solution is to simply ask document.cookie (and therefore indirectly on the contents of the Java vector election) in a defined - for example, every second - interval instead of immediately after the launch of the functionality of the device and only once. In this way, the app will be keep polling the vector object to the new answers PhoneGap and evaluate constantly.

  In all cases, you can not directly solved my problem, but you led me in the right direction! Congratulations to you, Sir!

  Thanks again,

• Application with cam on 8120 (4.5.0)

  Hi group. I developed an application that works normally in my 4.6.0 Simulator (9000JDE). When I push the button of my camera I opened a "screen of the device" which allows the user to take a picture. This image will be stored on the SD card with a predefined name device. The problem comes when I try to run my application on the 4.5.0. (JDE 8120 Simulator). The application works normally until I push my camera screen. And the problem in the same cams line according to survey an exception of media.

  A player = Manager.createPlayer ("capture://video");

  In any case, I did some research and I think I can't work like this. But maybe I could initialize the default camera app. The problem is that I Don t have control of stored thenames. Any suggestion?

  Thank you very much and sorry for my ignorance!

  The only way I know to get the picture from the camera on the old equipment is to

  Invoke.invokeApplication (Invoke.APP_TYPE_CAMERA, new CameraArguments());

  and use FileSystemJournalListener to retrieve the recently added files (first added and then changed) and use it.
