  Thanks in advance...

  Oky I solved the problem...

  using the...

  {if (g.isDrawingStyleSet (Graphics.DRAWSTYLE_FOCUS))}

  change the accent color
  g.setBackgroundColor (0xDCDCDC);
  g.Clear ();
  draw text
  g.setFont (Resize.getSecondFont ());
  g.setColor (Color.BLACK);
  g.drawText (item.toString (), 20, y, DrawStyle.ELLIPSIS |) DrawStyle.HCENTER);
  }

  inside the drawListRow...

  Thank you all...

• How to wear my java blackberry application to BB10

  Can someone please tell me how I can do?

  I have builf this from windows eclipse BB pluginh

  All the tools used? and no matter what other coding more?

  Thank you

  Java applications not supported for Blackberry 10, you must start with qt c ++ and Qml. see this link for abt blackberry 10 of info and tools:

• Java blackBerry Slider Bar

  HII, I created a scroll bar by referring to the example:https://github.com/blackberry/Samples-for-Java/blob/master/Advanced%20UI/src/com/samples/toolkit/ui/...,.

  hereby I am slider properly displayed on my screen, but my problem is next to the slider bar, I want to show a play/pause button, so i used the code below:

  SerializableAttribute public class UIExampleSliderScreen extends UIExampleScreen {}
  private ButtonField _startPlayingButton;
  Private ButtonField stop;

  private ButtonField facebookButton;

  public UIExampleSliderScreen() {}
  Super (0);
  _startPlayingButton = new ButtonField ("Play");
  stop = new ButtonField ("Stop");

  facebookButton = new ButtonField ("Facebook");
  facebookButton.setMargin (5, 5, 5, 5);
  HorizontalFieldManager Manager = new HorizontalFieldManager();

  setTitle ("cursor screen");
  final SliderField cursor;
  cursor = new SliderField)
  Bitmap.getBitmapResource ("slider2_thumb_normal.png"),
  Bitmap.getBitmapResource ("slider2_progress_normal.png"),
  Bitmap.getBitmapResource ("slider2_base_normal.png"),
  Bitmap.getBitmapResource ("slider2_thumb_focused.png"),
  Bitmap.getBitmapResource ("slider2_progress_focused.png"),
  Bitmap.getBitmapResource ("slider2_base_focused.png"), 20,
  0, 16, 16, FOCUSABLE).
  slider.setPadding (20, 20, 20, 20);

  slider.setBackground (BackgroundFactory
  .createSolidBackground (0xD3D3D3));

  Manager.Add (Slider);

  Manager.Add (facebookButton);

  Manager.Add (_startPlayingButton);
  Manager.Add (Stop);
  Add (Manager);

  }

  }
  }

  (1) I am able to show only the slide bar, my custom buttons are not displayed?

  (2) the sliding bar is displayed on screen, fully, how can I reduce the length of my slide Bar?

  the field of cursor seems to be designed to occupy the entire width:
  public int getPreferredWidth()
  {
  Return Integer.MAX_VALUE;
  }

  you have to change this, or replace available to the Manager.

• Need help breaking into Java/BlackBerry development / this sample project

  I have a ton of experience OO, but I am new to Java and I am trying to enter development for BlackBerry, and my first problem is being stuck with this defective sample app that comes w/Eclipse or JDE or something (they call it "CityInfo"). When I run the Simulator, I see the drop-down list box, but by selecting its members does nothing, and I don't know enough about the environment/language to understand why.

  I installed all the packages that are free. They are Eclipse (I can't find a version number), JDE, the Java plugin for Eclipse and the BlackBerry JDE 4.3 to 4.7 components Packages.

  And when this has been resolved, perhaps someone can show me a good set of sample applications with tutorials. I'm trying to follow http://supportforums.blackberry.com/rim/attachments/rim/java_dev@tkb/9/1/Writing_Your_First_Applicat... but it's not compatible w / the environment that I run.

  Here is the code for the project CityInfo:

  Hi and welcome to our forum!

  1. When you select item in your ObjectChoiceField nothing happens in terms of user interface. You must press menu and select "Details". Try it!

• java Blackberry multimedia is distorted when download resumes

  Hello, I'm developing a blackberry app and I'M having a problem while recovery of a download. The code works well if the download is not interrupted, but if it is interrupted and the download is restarted, the media file is distorted.

  To allow the resumption of the download, I request the file into segments from the server and persist the last piece of downloaded/written correctly. So if I have to restart the download, I check the last song downloaded and written, increment and to determine the scale at the request of the server.
  My code is listed below... :

      public final class Downloader extends Thread {

  I don't know where I am doing wrong. Help, please

  Finally this sorted out. What had happened was if the link turns off and I close the output stream, the calculation is distorted.

  So the next time I want to continue with the download, I'll open a stream of output at the end of the file and start asking the file to the server from the file size, for example, if the file size is 500 kb (already downloaded b4 network connection went wrong) then I'll start asking to between 500 - (500 + chunkSize) until the end of the file

• E-mail Info curve8310 using Java BlackBerry GPS

  Here is the code for blackberry GPS information sent to an e-mail address. The code uses sleep to send information at intervals.

  My problem is that when once that the GPS goes out of scope the application stops sending emails and no exception is thrown.

  If (lp! = null)

  {code}

  Sleep (65000);

  But it did not work for me.

  ////////

  public void run() {}
  While (! _stop) {}
  Address one;
  Store is Session.getDefaultInstance () .getStore ();.
  Records file [] = store.list (Folder.SENT);
  Folder sentfolder = files [0];
  Message m = new Message (sentfolder);
  SimpleDateFormat sdf;
                
  try {}
  LP LocationProvider = LocationProvider.getInstance (null);
  If (lp! = null) {}
  Location = lp.getLocation (60);
  Coordinates of c = l.getQualifiedCoordinates (); get the GPS coordinates
                         
  If (c! = null) {}
  Lat string = Double.toString (c.getLatitude ()); Latitude
  LNG chain = Double.toString (c.getLongitude ()); Longitude
  String alt = Float.toString (c.getAltitude ()); altitude
  Tim string = Long.toString (l.getTimestamp ()); timestamp
  String spd = Float.toString (l.getSpeed ()); Speed
                             
  String orgstr = "0449953853", + tim + ',' + lat + ',' lng + ',' + ', ' + alt;
  String googmap =http://maps.google.com/maps?q= "+ lat + ',' + LNG;
  String finalstr = orgstr + "\n" + googmap;
  a = new address ("[email protected]", "Aditya Tuli";)
  Address address [] = {a};
  m.addRecipients (Message.RecipientType.TO, addresses);
  m.setContent (finalstr);
  m.setSubject ("GPS Position";)
  Transport.Send (m);
  }
  } sleep (65000); moved to re - run the thread
  } catch (Exception e) {}
  System.Err.println ("an error occurred" + try ());
  System.Exit (0);
  }
  }
  }

  Please suggest.

  Thanks in advance.

  Concerning

  I think we have agreed that the problem is that it is there no LocationProvider or the getLocation is not a place, so to determine which of them seems to be the best place to start.  As you test on the device, you must debug on the device, you can connect by USB, starting the JDE, using the Debug/Attach To / Pocket PC, then select USB connected device.

  From there, you should be able to use the JDE debug, but according to levels, this sometimes does not work so well for me.  So I would like to add three statements of System.out.println (...), one at the beginning of the loop and the others inside each of the ' if.  This load on the device, then, once debugging started, simply wait for the missing output for each loop!

• Reverse Engineering - BlackBerry extract cod files java files

  I want to know if we can extract the files .java Blackberry since the .cod files? Is this possible?

  In the affirmative. How and what are the steps?

  And if not? Why? Because that would mean the violation of the security of the device blackberry app?

  I can't give a definitive answer to this.
  It is / was a decompiler of cod, but I don't know anyone who used it successfully to decompile a complex program.
  I gave a few hours test and never managed.

  even if you would be able to decompile a program, you would be a good step away from stealing stuff, but if you are concerned you can use of darkening additional layers or whatever.

  personally, I doubt that everyone would gain something by using the approach of decompilation and my experience shows that some decompiler exists does not work properly.

• QNX will replace the Blackberry OS?

  I have read a few forums, they said, QNX will replace Blackberry OS is this true?, then what the developer Java Blackberry supports, if new QNS will support legacy java blackberry applications

  Welcome to the support forums

  you will not be able to get an official statement from a RIM employee, I guess, they all NDAs.

  in regard to news on independent Web sites and rims clean news tell us it's going to be like this (my opinion):

  QNX will replace Blackberry OS

  BlackBerry Apps (j2me + bb-extensions) will continue to operate under the QNX in a clean VM

  Basically, this means that get us, as developers, the same thing that we now have a phone where our applications run and much more: Android support, native support, html5 etc pp.

  If the BB API will feature all, offer the best integration etc? We'll see, but my guess is that it is the most advanced in terms of integration (and the main objective of rims for things that cannot be solved with HTML5/Air)

• XML application and blackberry

  Hello;

  IAM develop an application that manipulate an XML from java blackberry applications, I have a few textField and I want to add the container of these fields in a file xml as a new tags, and I want to change the doc added to likely he fields is added in the same texyField I'll Likely and save changes to the xml file I made somes codes but it's not working if there is no tutorial or the method that works in BB request can we just send it to me, I'm stuck at this step.

  Thank you very much for help

  Hello. This forum exists to disturb us, so don't be sorry!

  Skimming just your code, I think that the line:

  CFile = (FileConnection) Connector.open ("dat.xml", Connector.READ_WRITE, true);

  may be causing the exception. Connector.open method requires the first argument a string in the format:

  {schema of}: [{target}] [{parms}]

  where {} is the name of a Protocol and is required. Your argument, 'dat.xml', is not a plan. Since you are built on a FileConnection, the Protocol should be 'leader '. Also, the target must be an absolute path name. A typical target for a file that is stored in the memory of the unit would be:

  'file:///store/home/user/dat.xml '.

  To the SD card, a typical target would be:

  'file:///SDCard/BlackBerry/dat.xml '.

  You can determine the roots of system file using FileSystemRegistry.listRoots ().

• Java sdk support

  Hello

  can someone tell me up to which version of the java sdk, we can use in blackberry.

  Java BlackBerry os is based on j2me, which is in turn based on java 1.4 (or 1.3?)
  in any case, you cannot use the api collections unless you implement it yourself.
  basically: use vector and hashtable.
