  I have a screen where I add my LocationPicker. I call add (locationPicker);

  I call this method before, to set up the locationPicker.

  private void readyLocationPicker(){

      locationpick.addElement(GPSLocationPicker.getInstance());
  
      Landmark[] landmarks = new Landmark[1];
      landmarks[0] = new Landmark("DC Beltway", "Center of 495 Beltway", new QualifiedCoordinates(LATITUDE_CENTER_OF_DC_BELTWAY, LONGITUDE_CENTER_OF_DC_BELTWAY, Float.NaN, Float.NaN, Float.NaN), null);

  I don't know what is happening and why it will not work.

  Thank you.

  Oh, it extends screen. Ridicule me. Here's how I got to work:

  locationPickerButton.setChangeListener(new FieldChangeListener() {
      public void fieldChanged(Field field, int context) {
  
          locationPicker.show();
          locationPickerButton.setLabel(locationPickerLocation.getName());

• Locator.geocode thorws IllegalStateException

  I want to have the latitude and longitude of an address, and I used

  Locator.geocode

  but it throws IllegalStateException, application is made on the event dispatch thread

  How can I solve this?

  is possible to use Locator.geocode in my application, because if I use Locator.geocode anywhere in the source it throws an exception,

  Since the javadocs:

  An application must ask geocode information outside the event sending thread.

  Start a worker thread, and make the call to the thread.

  }
  

  I found a solution that seems to work:

  Instead of the call

  mHomeScreen.add(mHomeScreen.myTextField);
  ...
  mHomeScreen.delete(mHomeScreen.myTextField);
  

  I tried to use

  mHomeScreen.getMainManager().add(mHomeScreen.myTextField);
  ..
  mHomeScreen.getMainManager().delete(mHomeScreen.myTextField);
  

  and the error disappeared.

• IllegalStateException when closing a screen in its constructor (single-threaded application)

  I use a screen that displays a list of items. The builder checks if there is nothing to display and if not, displays a dialog box with a message and call close(). The close() call produces IllegalStateException (on 5 BB). Why and how can I close or the screen?

  BTW, I read on do not call close() in a different thread, but in this case, I do not (at least in my code) any extra thread.

  public class MyScreen extends MainScreen implements ListFieldCallback
  {
    MyScreen()
    {
      super(Manager.NO_VERTICAL_SCROLL);
  
      int count = getItemsCount(); // A method that returns the number of items to display
  
      if (count == 0)
      {
        Dialog.inform("No item");
        close(); // throws IllegalStateException
        return;
      }
  
      // More irrelevant stuff here
  
    }
  }
  

  Thank you!

  My point was the call to close as the manufacturer, there is no possible way that the screen can be on the displaystack at the time wherever you call close...

  in another part of your code, you probably:

  uiApplication.pushScreen (new MyScreen());

  Push code will not happen before the end...

  I'm confuesd how do I call the method showAdrees() If you desire to process bluetooth backend made.

  Now I'm for names of Bluetooth and the storage in the RecordStore. but now the problem is how can I display on my main screen located in UIApplication.

  I am struggling to read this code, it seems not to be complete.

  Sorry, beginning with the obvious things, I assume you have another entry.  Usually one who has the 'gui' param starts the user interface, so I guess that BlueFreeBackround is the treatment of the user interface.  Seems a strange name?  But any.  We do not have this code, so can't review it.

  The other entrance is the one who starts the initial treatment.  In case you're MyUIApp.  But you have this:

  If (appMang.inStartup ())
  return;
  Also if this is executed at boot time, the treatment does nothing.  And you start an application that seems to be the associated user interface.  I'm confused.  And we have no code to the constructor for this class, so we can not comment on that either.  All we know is that this class sends a global event.  Now, if I'm wrong, I don't think you need to start an Application to send a global event.  It is enough to have one to receive a.

  And you have given us another class, but there is no indication how it is started.  Assuming that it is started, it will receive the global event and execute the firststart() method.  Confusingly, this method will start a Thread that starts a timer.  Why can't firststart() him and save a Thread and some confusion?

  OK, now we come to the TimerTask, which is launched every 30 seconds (seems too often to me, but maybe not).  This process begins the investigation.  And we arrive at the point of this thread.  InquiryCompleted, I think you want to call showAddress().

  It's actually easy, although I really don't like this approach:

  Instead of using

  postGlobalEvent (long guid);

  use

  postGlobalEvent (long guid, int data0, data1, object0 object, Object1 int);

  and pass the MyUIApp object as a parameter object0.  Then, you can call

  . showAddress();

  I suspect that this will throw IllegalStateException, so you'll need to hire a

  this.invokeLater (...)

  to ensure that you have the thread of events when refreshing.

  But if I were you, I would consider this approach.  It seems some unnecessary steps.  For example, why doesn't MyUiApp start the discovery itself, what s at the point of the AppBackend?  A; Otherwise, you use a global event to initiate treatment, you could send the data in another GlobalEvent.

• BlackBerry JRE 5.0.0 BrowserField has no ScriptEngine

  Hello

  Ive got a BrowserField:

  BrowserFieldConfig config = new BrowserFieldConfig();
  config.setProperty (BrowserFieldConfig.JAVASCRIPT_ENABLED, Boolean.TRUE);
  This.Browser = new BrowserField (config);

  which returns the null value on:

  this.browser.getScriptEngine ();

  Prevents me to run scripts from the code Java, because browser.executeScript ("somejavascript"); throws IllegalStateException which States that there is no such thing as the ScriptEngine. Which is kinda funny, because when I load JQuery its able to compile the script and the BrowserFieldDebugger tell me, that JSON is not defined. Which is exactly why I want to run a script inside the Java code from in the first place. Well, I need to call javascript functions later as well so I would have needed this feature in one way or another. BTW. : browser.displayContent (' javascript : somejavascript ", someurl" ") seems to generate a kind of error page.

  Test on a 9700, build against BlackBerry JRE 5.0.0

  ID like to have this app running next Thursday, a quick (and useful) answer would be appreciated (if you need more information, ask away).

  Thanks in advance.

  Sorry not an area of expertise, but I have some thoughts.

  Copy the following code

  invokeLater (new Runnable() {public void run() {}

  thing to run

  (}, 500, flag);

  you continue to repeat if the flag is true initially (it is not re-evaluated).  So I think you really want to code something like:

  Runnable testScriptEngine = new Runnable() {}

  public void run() {}

  ScriptEngine scriptEngine = mdBrowserField.getScriptEngine ();

  If (scriptEngine == null) {}

  invokeLater (this, 500, false);

  } else {}

  Dialog.Alert ("found Script engine");

  }

  };

  invokeLater (testScriptEngine, 500, false);

  If I was looking for something that could be triggered when the browserField 'worked', I would look at the method documentLoaded() of the BrowserField listener:

  http://supportforums.BlackBerry.com/T5/Java-development/BrowserField-sample-code-using-the-BrowserFi...

  I'm guessing it is significant above using a Script engine, so I can see a reason to not create a Script engine up until you need it - so it does not surprise me that one is not created in BrowserField instantiation.

• browserField.executeScript

  Hello

  I'm stuck with a question on the addition of a browserFieldListener. I have a native application BlackBerry accessing a web application using the browser. I have a JavaScript block in a specific page. I want to use browserField.executeScript ("my javascript in a JSP page") and check the returned Boolean value when I ask for each page. So I replace the documentLoaded method and add the inside executeScript method. However, she always throws IllegalStateException when browserField.executeScript. After I go through the RIM API, I found it refers to the exception as " IllegalStateException -this exception is thrown if this method invoked before this BrowserField document has been created." This event is communicated via the BrowserFieldListener.documentCreated () method. "Someone has suggestions or comments here, please? Thank you very much.

  I finally understand this problem. He won't do the method of excuteScript in documentLoaded() of BrowserFieldListener since the scripts contained in the document cannot be invoked until the document is loaded. I think it makes sense. So if you want to do stuff like read the DOM to call javascript from your document, make sure that the action happens after all the document is loaded. The original intent of my code is kind of like: use the browser to open a web page, check some flag from this page, generate a menu browser dynamically customized for this indicator. So now, I put all this reading document action in makeMenu and this method would make sure all the action happening after the page loads.

• Scrolling ListField

  I read many more posts scrolling ListField and they helped me to get that much, but now I'm stuck.  I have my list field in a VerticalManager with scroll work.  I set it up so that there are 5 visible rows in the ListField.  However, when I scroll down past the last visible line (there is currently a total of 9 lines of the list), paint lines is no longer the text of the line.  I developed a custom implementation ListField, who has a foreground and background color.  The idea is that each line is focused, switch foreground and background of color - the selected line a deep Navy with white text and unselected lines have a white background with marine text.  Works very well for the visible rows, but when I scroll beyond rank 5 to reveal the invisible lines, they just paint with the Navy background and white text.  Here's my class of custom list field (which was based on something that I found on a forum or in the knowledge base):

  If the ListField has focus determine the selected line.
  rowHeight = getRowHeight() int;
  int currEntry = redrawRect.y / rowHeight.
  int lastVisibleEntry = (redrawRect.y + redrawRect.height - 1) / rowHeight.
  lastVisibleEntry = Math.min (lastVisibleEntry, getSize() - 1);
  int y = currEntry * rowHeight.

  int curSelected = hasFocus? getSelectedIndex():-1;
  Draw each line
  for (; currEntry<= lastvisibleentry;="">
  {
  graphics.setColor (currEntry == curSelected? bgcolor: fgcolor);
  graphics.fillRect (0, y, redrawRect.width, rowHeight);
  graphics.setColor (currEntry == curSelected? fgcolor: bgcolor);
  graphics.drawText (getCallback () .get (this, currEntry) m:System.NET.SocketAddress.ToString (), 0,)
  y);
  Assign new values for the y-axis move a row downwards.
  y += rowHeight.
  }
  }
  }

  Here's how I instantiated class:

  private int screenW = Graphics.getScreenWidth ();
  private int screenH = Graphics.getScreenHeight ();
  private int listWidth = (int) (screenW * 0.95);
  private int listHeight = (int) (screenH * 0.4).
  private ColoredListField myListField = new ColoredListField)
  listWidth, listHeight, selectedFGColor, selectedBGColor);

  Also, here is my point:

  private static class DiaryEntryListCallback implements ListFieldCallback
  {
  private DiaryEntry [diaryEntryList];

  public DiaryEntryListCallback() throws Exception
  {
  diaryEntryList new = DiaryEntry [0];
  init();
  }

  public void init() bird Exception
  {
  DiaryEntry [] tmpDiaryEntryList =
  DiaryDAO.instance () .getDiaryEntriesAsArray (true);
  If (tmpDiaryEntryList! = null & tmpDiaryEntryList.length > 0)
  diaryEntryList = tmpDiaryEntryList;
  on the other
  {
  diaryEntryList = new DiaryEntry [1];
  diaryEntryList [0] = new DiaryEntry ("No data",
  Calendar.getInstance ());
  }
  }

  public void init (DiaryEntry [diaryEntries]) throws exceptions
  {
  diaryEntryList = diaryEntries;
  }

  public int getNumberOfRows()
  {
  Return diaryEntryList.length;
  }

  ' Public Sub drawListRow (ListField l, Graphics g, int index, int y, int w)
  {
  draw text is managed by the implementation of the custom list field
  }

  public {get {Object (ListField listField, int index)
  {
  return diaryEntryList [index];
  }

  public int getPreferredWidth (ListField listField)
  {
  Return listField.getPreferredWidth ();
  }

  public int indexOfList (String prefix, ListField listField, int start)
  {
  int size = diaryEntryList.length;
  for (int i = 0; i)< size;="">
  {
  DiaryEntry currEntry = diaryEntryList (DiaryEntry) [i];
  If (currEntry.getEntryText () .toLowerCase () .startsWith)
  (prefix.toLowerCase ()))
  Return i;
  }
  Return listField.getSelectedIndex ();
  }
  }

  And here's where I build the main screen, adding the list field and other areas:

  Private Sub createMainScreen()
  {
  mainMgr = new ColoredVerticalManager (selectedBGColor,
  Manager.USE_ALL_HEIGHT);
  listMgr = new ColoredVerticalManager)
  selectedBGColor,
  Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);
  mainMgr.add (diaryEntriesLabel = new FixedWidthLabelField)
  "' Diary entries:»(, listWidth,-1, selectedFGColor, selectedBGColor));"
  Try
  {
  listCallback = new DiaryEntryListCallback();
  diaryEntriesListField.setSize (listCallback.getNumberOfRows ());
  diaryEntriesListField.setCallback (listCallback);
  diaryEntriesListField.setFocusListener (new DiaryFocusListener());
  listMgr.add (diaryEntriesListField);
  mainMgr.add (listMgr);
  }
  catch (System.Exception e)
  {
  Dialog.Alert ("error when loading of list one diary entry:" + e.getMessage ());
  }
  mainMgr.add (selectedEntryLabel = new FixedWidthLabelField)
  ((' Selected: input: ",-1, -1, selectedFGColor, selectedBGColor));
  mainMgr.add (diaryEntry);
  Add (mainMgr);
  }

  Clues as to why when scrolling past the visible lines, he stops painting?

  Thank you

  Hello

  You want listfield fixed size with active scroll.

  Please try the following solution:

  Removed listfield class the following function:

  public void layout (int width, int height)
  {
  setExtent (fixedWidth, fixedHeight);
  }

  That you override the trace of the listfield, the measure will be defined as a fixed height. Therefore, you have noticed that Manager of vertical field scrolls but listfield not scroll.

  Please override method 'sublayout' of vertical field Manager "listmgr":
  VerticalFieldManager oVerticalFieldManager = new VerticalFieldManager (MainScreen.VERTICAL_SCROLL |) MainScreen.VERTICAL_SCROLLBAR)
  {
  public int getPreferredHeight()
  {
  Return nFixedHeight;
  }
             
  Rewritten to define the visible height for the vertical field Manager.
  protected void sublayout (int width, int height)
  {
  height = nFixedHeight;
  Super.sublayout (width, height);
  setExtent (width, height);
  }
  };

  This code works for me fine.

  Kind regards

• is authorized to build the screen over the events, but push over the event

  Hi all, I know it's a lame question, but I get an error message and now then guess myself

  the way I coded this app. I usually build screens in a non event, calling thread

  Add when adding fields and all the UI stuff, but once it is done, then I put the pushScreen

  in the case of threading

  is it ok?

  Well, it is certainly not a "lame".  I guess you can add fields to a form on a thread of non-event so the screen is not "displayed" (do not push in the battery of the screen still), otherwise, you will need to run that add inside invokeLater or while now the lock of the event.

  Say, if you pushScreen (MyCustomBackgroundCreatedScreen()) new, some of the screen building code can be executed before the screen is actually pushed and the rest will be executed after that.  The "suite" party (whose actual start is quite random) will throw IllegalStateException unless you put your add code (...) within invokeLater or synchronize the lock of the event.

  I did it myself - parses an XML file in a separate Thread and by creating and adding fields one by one to a display manager - and I distinctly remember having to do it the way I described.

  If it's OK or not depends on your design.  If you have only a few fields to add, that's fine, I guess.  Each addition will cause the entire screen to rearrange, which is a small performance decrease. However, unless you have a few fields of thousands (I remember this post here in the forum), you should not notice a significant slowdown.

• MP3 not "playing on Simulator for storm 4.7. *

  Hello

  I have a problem where I like to read mp3 in the file system on Simulator.  I have traced the SD card in my pc file system. The code works for all simulators I've tested except models storm running 4.7. *.

  The SIM for 9500 5.0 running works well.  The code has also only a problem for all the ringtones I got from Crackberry ringtones, but it works on my own mp3s.

  I've narrowed the problem to player.start that throws IllegalStateException.  I checked my permissions are ok - IE.  the application has permissions to media.  I checked the files played on the BB Media Player.  the code is pretty generic - get the file connector, open the input stream and start the player.

  Someone sees this sort of thing on storm 4.7* simulators?

  More strange findings (error checking and various removed).  For specific MP3, on the storm 4.7. * simulators

  It works:

  Reader = javax.microedition.media.Manager.createPlayer (pathToFile);

  This is not:

  fconn = (FileConnection) Connector.open (pathToFile);

  ringToneInputStream = fconn.openInputStream ();

  Reader = javax.microedition.media.Manager.createPlayer (ringToneInputStream, "audio/mpeg" "");

• Problem at the opening of the start screen

  Hello

  In my BB app, I want first of all to display a splash screen and then go to the normal screen. To do this in my main Uiapplication, I call you:

  SerializableAttribute public class MyAppStarts extends UiApplication {}

  public MyAppStarts() {}
  pushScreen (new SpalshScreen());
  }
  Public Shared Sub main (String [] args) {}
  MyAppStartsapp = new MyAppStarts();
  app.enterEventDispatcher ();
  }

  }

  It's my inspired SplashScreen (excerpt) of http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/800505/800256/...

  She throws IllegalStateException - does not know where. I tried to add the breakpoint at the pushScreen of the main class (new SplashScreen()); but it throws the exception and could not know where the exception. If I replace the SplashScreen with LoginScreen, it works perfectly. There is something wrong with the SplashScreen.

  Can anyone help mw know where I'm going wrong or what more to do!

  Any help is very appreciated.

  Thank you

  Oh thanks for pointing this error.

  After correcting this error also, it did not work at all. Finally I erased applications for download folder (could also just delete my those cirrent requests) and tried again and it worked perfectly.

  I guess the main problem is also the same application was already in the download folder was running even JDE and proper application in the cache to perform instead of newly added or updated to date.

  Just to see the results with invoking pushScreen again n SpashScreen Builder - resutls were still only works correctly. Not a Sunrise errors/exceptions or screen showed two times or more - everything worked as expected. Hmm strange.

  Any ways thanks.

• How to avoid the blue color of a LabelField default selection?

  Hello

  Below, I have given my code please review and let me know where I did wrong. because my requirment must show the labelfield with a specific color. not work but useless default blue color is coming with the text. I want to avoid that the color blue.

  final String dimensionally = 'Test ';
  LabelField lbl = new LabelField (slable, 0, slable.length (), LabelField.FOCUSABLE |) LabelField.HIGHLIGHT_FOCUS) {}
                          
  Do police = Font.getDefault (.derive(Font.UNDERLINED |)) Font.PLAIN, 12);
  int x = font.getAdvance (slable);
  int y = font.getHeight ();
  Boolean hasFocus;
  protected void paint (Graphics g) {}
  g.setColor (Color.BLUE);
  g.setFont (do);
  {if (HasFocus)}
  g.setColor (Utility.ACTIS_MAAROON_COLOR);
  g.fillRoundRect (0, 0, x, y, 10, 10);
  g.setColor (Color.WHITE);
  g.drawText (dimensionally, 0, 0);
  } else {}
  g.setColor (Color.BLUE);
  g.drawText (dimensionally, 0, 0);
  }
  Invalidate();
  Super.Paint (g);
  }
                         
  protected boolean trackwheelClick (int arg0, int arg1) {}
  //

  }

  protected void onFocus (int arg0) {}
  hasFocus = true;
  super.onFocus (arg0);
  }

  protected void onUnfocus() {}
  hasFocus = false;
  super.onUnfocus ();
  }

  public void select (boolean arg0) throws IllegalStateException {}
  Super.Select (false);
  }
  /*
  Protected Sub layout (int width, int height) {}
  width = x;
  height = y;
  Super.Layout (width, height);
  super.setExtent (width, height);
  }
  */
                         
  };

  and one last thing is that when I method of positioning cover font size is bigger.

  Please answer...

  drawHighlightRegion is used to paint the selection, see also drawFocus.
