• Problem with the BlackBerry Developer Site

  We are currently experiencing a problem with the integration of BlackBerry ID with the BlackBerry Developer web site.  This prevents the developers to create a new BlackBerry ID Token, connecting Issue Tracker and Developer area and potentially other areas that require authentication.  Trying to access one of these pages gives the following error.

  Sorry, there is a problem with the page you are trying to reach and it cannot be displayed. Please try again later.
  

  Teams are trying to solve the problem.  We apologize for the inconvenience.

  The problem has been resolved.  You should now be able to connect Issue Tracker and generate BlackBerry ID chips again.

• Problem to connect/disconnect blackBerry Developer Web site

  When I connect to the BlackBerry Developer's Web site (http://developer.blackberry.com) Safari (6.0.4) on my Mac (10.8.3) a bunch of weird files have been downloaded in my downloads folder. File as: GnCYWDHJWbM, UXEt5tfUEdc, etc...

  The same thing happens when I logout on the developer site.

  Is anyone else facing this problem?

  Although we can say that it is corrected now.

  If someone else has the same problem, however, please let me know.

• Z10 blackBerry development mode

  Hello!

  When I go into Settings/Security/Development mode, I can:

  • activate this,
  • specify an IP address for the development,
  • install a token "debug".

  (if I translate well to the french).

  Could someone tell me more about these options?

  Is there a security problem if I try and install the debugging token?

  The token lets connect you the phone via ssh (among a few other things.)  You don't always have root access on the same phone with installed.

  With mode on you can sideload apps debugging, but they must always be signed (by someone with a BlackBerry Developer certificate, which could be you.)  Without development mode on the phone will not allow direct loading of applications via the interface USB at all.

  For purposes of sldeloading, there is no need to install the debugging token.

• BlackBerry development environment - SDM does not

  Hi all

  I put in place following the BlackBerry development environment.

  1 blackBerry JED 4.7

  2 blackBerry Email and MDS Simulator 4.1.4

  3 blackBerry WebLoader 1.1.0

  If I try to run the MDS through the stand-alone option (Option 2 above). SDM works very well and I am able to access the Internet while browser.

  But if I try to run MDS if the option provided internal JDE (Option 1). SDM is not running. Command window opens for the fraction of a second and then closes. Some how I managed to catch the snap-snap-in error and which is "Exception in thread"main"java.lang.UnsupportedClassVersionError.» Bad Version in .class file number' do not know what the problem is.

  According to my understanding MDS should work in both options.

  Please provide your inputs.

  Thanks in advance,

  Sandeep

  Baiscally the MDS is to simulate the transfer of your data through MDS.

  Well, if your Java version is compatiable with the MDS, avoid any problems for MDS.

• Call the JavaScript file java class in the native blackberry development.

  
  

  What you are looking for is the ScriptableFunction class.

  You can extend the script engine of a JavaScript object name to a ScriptableFunction Java class mapping.  In this example, if you called foo. JavaScript bar(), the BrowserField would facilitate a call to the invoke() method defined in the MyScriptableFunction() class:

  protected BrowserField _browserField   = null;
  _browserField = new BrowserField();
  _browserField.extendScriptEngine("foo.Bar", new MyScriptableFunction());
  

  Then you set your ScriptableFunction class like this and fill it with some Java code, you need.  Note: it only accepts strings as input parameters.

  import net.rim.device.api.script.ScriptableFunction;
  
  /**
   * @description Demonstration of using the ScriptableFunction class added to version 5.0 of the BlackBerry Device
   *              Software

   * @category BlackBerry BrowserField Development: ScriptableFunction API

   */
  
  /**
   * This class can be used to represent a function in the JavaScript environment.
   */
  public class MyScriptableFunction extends ScriptableFunction
  {
  
      /**
       * User has invoked this ScriptableFunction from the JavaScript engine This example shows how to open the Messages
       * application and create a new message
       */
      public Object invoke(Object obj, Object[] args) throws Exception
      {
          if (args.length == 3)
          {
  
              String param1 = args[0].toString();
              String param2 = args[1].toString();
              String param3 = args[2].toString();
  
              //Do something
          }
          return Boolean.TRUE; //Always
      }
  
  }

• What are the concepts that we should brush upward in java to be a good blackberry developer

  Hi, if I am not new to java and blackberry, but I don't know where to start when an advanced blackberry application is given to me to develop I feel like that because maybe I need to brush the concepts in java more carefully, cannot therefore a whole list important concepts I should know inorder to write any application for blackberry.

  For me, this could be the list:

  (1) thread

  (2) networking

  (3) vector and manipulation of tables

  (4) exception management

• A few questions for the first blackberry development

  Hello

  First of all, my apologies for this being placed in the Java section, it seemed, the nearest section of what it is, but please move if need be.

  We have an application in development for the iOS platform that uses some geolocation and Web services.  We believe that we should have a version for the blackberry also platform, so we're looking in this evolution.  However, not being not to developers or users of blackberry, the different options for creating an application are quite overwhelming.  My questions are the following:

  (a) what language (Java?) is the most compatible?  Ideally, we would like to write the backend once, don't have to change the interface for devices of the curve through to the new playbook.  Java is also based on all of these devices?  None of us have any idea of Adobe Air, this is probably out of the question.

  (b) what are the operating systems are supported by what?  The curve I picked up seems to have Blackberry OS5 on it.  All operating systems support Java everything too, and whose support wifi location and cell tower map (the curve does not have a GPS unit).

  (c) I understand that during the development in Java there is a blackberry UI api, that's fine.  However, what version of Java is supported?  Is - this SE6, or we are talking about mobile Java here?

  (d) distribute the Apps.  The Blackberry App World seems to be the best route.  Do most people use?  It seems that the Blackberry is not restricted like iOS devices in how applications can be distributed.  Is there any other App stores (e.g. Amazon for Android?).  I guess it would be silly not not to enumerate the BB App World.

  Thanks in advance, any help is much appreciated.

  S.

  It is a really difficult game of questions.

  (a) Yes is the short answer.

  The long answer involves noting that the PlayBook does not directly support Java, and development platforms only available to this end are currently Adobe Air and Web works.  I can't give you a good explanation, since I dabbled only in them, but in summary,

  (a) with Web works you are essentially creating a Web application using HTML and JavaScript, with some JavaScript interfaces to the native operating system

  (b) air seems to me be in another development environment where screens and treatment are defined in a "Scripting" language that runs on the device.

  Work Web development is possible on the current BlackBerry phones as well, although I have no idea how compatible the two are - in other words how much you would have to change to a PlayBook Web app works works on the Palm and vice versa.

  I suggest you ask a similar question in the forums for these two platforms and see what they say.

  Anyway, there is a train of thought that phones current based Java will stop at some point, and phones will become based QNX, as PB.  So right now, if you want to learn something, then Web works.  But the works Web will be able to do what you want?  I don't know, but I don't know that Java is.

  But whatever the customer, you should be able to write the backend once.  Everything should speak http towards it.

  (b) there is not a BONE by device. Most devices come out with only one level and can be upgraded, usually at the next big release.

  Take a look at this good:

  http://us.BlackBerry.com/developers/choosingtargetos.jsp

  OS 5.0 in theory supports the location of the cell tower.  I say in theory because I never had to work in the United Kingdom.  But I have not tried very hard.  In my view, WiFi is available in the OS 6.0.

  (c) blackBerry support J2ME, with a significant number of extensions.  Think of it as Java 1.4 without all the useful bits, but the then RIM tried to add their useful in bits.

  (d) cannot speak for others, but BB App World is all I use.  Tried another one and didn't get anywhere.  YMMV.

  I hope this helps.

• 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!

• New in BlackBerry Developer aplications

  Hi all! I'm new in the development of BlackBerry and I have a question:

  API of witch I can use to get the imei of the device? How can I use?

  Thanks for all! And I want to apologize for my bad English...

  If you had read the API, you might find a method:
  public static String imeiToString (byte [] imei)
  Converts the value of the International Mobile Equipment Identity (IMEI) in a string.

  You can try to use in conjunction with
  public static byte [] getIMEI()

  not very surprising to see gibberish, if you try to use the method toString to a byte array.

• Password blackBerry BlackBerry Developer 10

  Now, I could have put a messing around but I would probably not be forgotten, anyway around it or reset?

  Thanks in advance

  It would be the same as the main security password on the device. Do you know what your security password?

• Helps the RichList and managers for a new Blackberry developer

  Hi all, I searched through the blackberry Quick reference Guide as well as the API on get a RichList to work in my application. However, I'm not entirely sure how Managers are used (I'm building my little app using the latest version of the BB SDK, 7.1). Here is my code (Simplified): http://pastie.org/4163177

  Basically, my screen pushes this full screen and it provides a Manager. I did this is because getManager() did not work (getManager() returned null, so I got an error), so I pushed the Director of the screen through. Now my list does not appear on the screen. So my question is: how to use managers, and how do I get my RichList appears?

  using menuManager which was transmitted through my screen:

  

  using getManger():

  

  A handler can be added to a single screen.  Try to use your screen in your full screen Manager (or any instance of another screen) will not work.  I recommend reading this guide on the managers. Let us know if you have any questions after checking that.
