Screen orientation: real device vs. Simulator

• Custom BrowserField appears in the real device Simulator only

  Hey guys, I got some piece of code that I can use to display HTML data stored in a variable. It worked fine in the Simulator, but when I tried to view it on a real device (I use 8900), it shows nothing.

  Here is the code (HTMLField.java): (I use the code here: http://supportforums.blackberry.com/t5/Java-Development/Display-HTML-in-a-Screen-Field/td-p/335074/p...)

  Is there something wrong with it?

  Yes, as I finally tried again and again, it seems that the OS 5 does not support old stuff like that, it has its own browserfield2.

• A simulator to simulate efficiently all limitations of a real device?

  I brought an IPhone app to BlackBerry and it works great on the Simulator.  One of IPHONE developers theother said day "wait until you get your application on the actual device. That's when the pain begins"and he stopped dead in my tracks. The big question is, it works perfectly in the real device too. Is the Simulator has the processor, memory, and any other restrictions of a real device?

  PS. can't afford a real device, so stuck with the blessed simulators.

  See you soon.

  Not sure that I count as a guru, but happy to offer my thoughts.

  Basically, I agree with the previous answers, you've had.

  Not sure if anyone has mentioned code signing and prompts security/permissions variety you can get on a real device.  I would recommend that you get the key signing, even if you need and sign your code for $20.  There is a good video on security prompts that I recommend that see you, too.  And business users would never be able to run your application due to the security provisions in the company.

  Relating to the performance, don't forget that the Simulator is faster than the device.  Much faster.  The one that annoys me is the time it takes for a page in the browser.  I have not done much image manipulation, but I think that the same thing happens with her.

  Concerning the aspect, the storm must be the biggest difference.  Remember that you are using a mouse on the simulator that is easy to point.  The simulator of life-size scale and then try to put your fingers on the screen to see if your fields are in fact quite large.  And you will find the keys on the real QWERTY devices a little different and surprisingly, different between different models.

  Get cod on the device takes a little thought.

  If a few other things, but the guys have already hit on the most important.

  Hello

  No. 1: If you started the Q10 Simulator, it is expected for the real device has a physical keyboard. The Simulator startup, select the Z10 and test again to get the virtual keyboard.

  2: this question would better fit for a new topic. In any case, a strategy would be to cut the long cards for the smaller pieces and loading them dynamically, effectively keep in mind a few.

  I have a problem downloading a real device file

  on real device the size of the file to the file will always be-1

  but on the Simulator, he will get the actual size...

  is there a problem with my code?

  There's a thread sticky in this forum, created by peter_strange:

  HTTP code and Access BIS-B connection example

  In my opinion, it is better that most of the books of BlackBerry - read it!

  The isssue is not exactly with your code - it is with the different ways in which the BlackBerry can connect to the Internet. Unfortunately, even a 'simple' download becomes a non-trivial task on it.

  See if playing with suffixes connection solve the problem - it could, it could not

• Application of background visible on a real device (all well in the Simulator)

  Hello

  I developed a small backgroundapplication, which shows a menu entry in the app phone "call via Asterisk. If I choose this option a defined number is called. Later, I want to add the number as dtmf tones.

  The application uses excactly as expected in the device Simulator 8310-JDE (included in the eclipse plugin) on JDE 4.5. with eclipse.

  But when I deploy the application (signed) to a real 8310 with firmeware v4.5.0.81, it appears an application icon on the desktop (homescreen) of blackberry and the menuentry in the phone app is missing. Why the application is not deployed as a background on the real dev app. ?

  The only difference between the Simulator and real device is the language chosen, but I don't think it's important.

  The application consists of files, as shown below.

  import net.rim.blackberry.api.menuitem.ApplicationMenuItemRepository;import net.rim.device.api.system.Application;
  
  public class Asterisk extends Application {   public static void main(String[] args)    {            // Create a new instance of the application            // and start it's event thread.            new Asterisk().enterEventDispatcher();    }
  
      public Asterisk()    {        //create a new instance of the menuitem       AsteriskMenuItem asterisMenuItem = new AsteriskMenuItem(40);
  
        //get the instance of the standard-menu an ad the new menuitem        ApplicationMenuItemRepository     .getInstance().addMenuItem        (ApplicationMenuItemRepository.MENUITEM_PHONE,asterisMenuItem);

  The entry for the RRT signature was missing in my .csl file. I change it manually, I added

  '52525400 = RIM API execution' requested signatures, deployed and it works...

• 9900 screen orientation problem

  Hello. I had a problem on problem of orientation.  Only 9900 real device got this problem (the other deivce is ok as Simulator 9810 and 9900 also ok.).

  I put the direction of the screen like this: Ui.getUiEngineInstance () .setAcceptableDirections (Display.DIRECTION_PORTRAIT);

  But management screen show always reason to 9900.

  Did someone also get this problem?

  Pls share the solution. Thank you very much.

  This is perhaps because previous models could not rotate the screen -?  Only touch screen models.

  All other models are either a touchscreen where North is the same as the Portrait is a non touchscreen where the display is always North either portrait or landscape.

  So just check AccelerometerSensor.isSupported (), and if that returns false, you know it will always be in the North either portrait or landscape.

  If what you're trying to do is to make the display always be oriented as when the phone is held normally, then set the acceptable to the north direction, and it should behave the same on everything... except that the Storm, the display does not obey a command to move a certain way, it will remain however is that the app was started , but then lock in the North, if the user does rotate this portrait.

• Place of current residence (Longitude/Latitude) GPS does not work on real device

  Hello

  I wrote a small test application for GPS/latidue longitude. It works fine on simulator (9630), but not on the real device (BlackBerry Tour). Am I missing something?

• How to develop and test the application mobile flex without the real device?

  I'm trying to read some information about it, but decided to ask also here.

  I have a project that has a company wants to grow me, it's for iPad. That's ok I am with Flex and the framework for web development, but not for mobile. Why? Because I have no idea how to test my application. I know generation ago it sort of the desktop version of the application with the change of the "back" button on the orientation stuff, but how do I know my application will look and work exactly the same (I mean NOT performance here). I mean you know how every android or iOS device have their native keyboard or native video player for example and I have only in the debug version of the application.

  The question is how to develop this application based on the desktop emulator or anything and then hope that my app looks and works on a device, as it should... Of course I can't afford to buy all the devices it is just to be able to test on it if necessary? So, how do you, how to test how my iPad app works on a device without a? I know I should get a licence from iOS dev to be able to package the app for iOS, but it's $ 99 per year or something like that I can handle, but how to test my application without having to buy the darn device? Are there any emulator for iPad or something like that I know what my customers will see when they get the application? One of my friends told me that the mac os x use the developers a tool - cause some kit of dev who has emulators for all iOS devices and you can build and test there immediately and that you can simulate virtually any combination of key for example, and he said he's working and seems to 1:1 as the real device but he didn't know if can I export an AIR application and try it like this, he only knew for app written in native code.

  If someone can just tell me how should I do this? Should I buy a mac os x computer laptop to test because I am a user of windows 7, or perhaps create a mac os x virtual machine and tests out there or maybe the only option is to actually buy the device... that would be terrible for a freelancer...

  I hope someone can save the day here! Thank you.

  Since the AIR for iOS applications are compiled to ARM code you will not be able to run on iOS emulators running on Mac OSX.

  You can do a very simple test with the "Simulator" built into Flash Builder, but it is not much more than a window to AIR with a window size that matches the resolution of the selected iOS device.  When running in the simulator of the application is not compiled to ARM code so it will take a completely different code path than what will be the final release of iOS.

  Ultimately if you are developing for iOS with AIR nothing but for tests on real iOS devices.

• The difficulty to launch android applications reconditioned on device PlayBook (Simulator OK)

  Just updated my android app and it passed verification.  I will install on my PlayBook, and it won't start.

  The application works on the new 2.0 PlayBook Simulator very well, but when I go to install on the current device, it installs, but will not start.

  I tried without success (all these I tried both USB and WiFi connection) the following:

  • Restart the PlayBook after the 2.0 update (several times)
  • Signature of the bar and the deployment using command-line tools
  • Do not sign the bar and deployment via command line tools (after configuring Debug token)
  • Deployment by using the new eclipse plugin - is to expire, I have even increased the time-out value of 60 seconds and much more), it gets stuck on "Launch BlackBerry Android Runtime."... ", then a message that says" failed to connect ├a 192.168.1.139 to BAD! »

  Also, I'm under Mac OSX Lion and v2.0.0.3778 PlayBook.

  Anyone else having any of these issues or having luck getting your reconditioned apps to run on the real device?

  Any of you installed a pre-beta version of an Android player that has been disclosed on another forum?

  Whether a security wipe can be in the order that I suspect that the two versions of the player are probably in conflict!

• Impossible to debug on real device

  Hello

  When I try to debug an application on a real device debugging I get an error that a debug file is missing.

  After the tutorial on http://supportforums.blackberry.com/rim/attachments/rim/java_dev@tkb/18/1/How_to_Debug_and_Optimize _... he said that I may receive this error if "the reason why this might happen is that the version of the software on your device does not correspond to the.
  the software version of your Simulator

  I use blackberry curve withDevice software versio 5.0.0.103

  The research unit of the Simulator for OS 5.0.0 it does'nt seem to be a simulator for this version of the software.

  What can I do?

  You must launch the application manually on the device. I don't know why the breakpoints are not recognized. Try to delete the app, reboot the device, the app package, sing, load (debug as)... you can tell that the debugger is attached with success by the lines displayed in the Console view.

• HttpPushDemo throws the error of missing on real device resource

  I am trying to run the example of httppushdemo on a real device to test for problems with an application to push.  However, if I run the application in the device, I get the error "Missing resource com.rim.samples.device.resource.HTTPPushDemoRes.

  I looked everywhere to find out how to get the resource on the device and impossible to find a solution.  The documentation I found would lead me to believe that it should be compiled in the Cod.

  Why I'm so confused (and frustrated after a long day of our push to debug problems)

  Thank you

  -Bill

  In older levels (4.3 and earlier OS), RIM ran the code, so that the resources (labels field, the names of menu etc.) where in a separate package.  It's a good way to demonstrate how you could internationalize applications, but also everyone confused because putting the application on the device, you need to charge upward of the cod resources as well.

  At the latest OS (4.5 +), they do not do this.

  The demo of http push has not changed, so you can take the source of the 4.5 or later in a previous level JDE and compile it.  It will take so NOT all external files of cod.  That's what I recommend you do.

  However, for you to win download the JDE together for a single file, it is here:

  I'm a new java developer using Eclipse plug-ins. every time when I had mistakes, only to debug codes on the Simulator, but I want the debugging on a real device. I already sign with BlackBerry $ 20. You guys can tell me how, please?

  Thank you

  Concerning

  In Eclipse:

  - Run > Debug Configurations...

  -Click Terminal BlackBerry on your left and then click the new (blank page with star.

  - Check the projects you want to deploy on your device.

  -Click the general tab and select debugging under "display in Favorites menu".

  -Make sure that your device is connected, and then press the debug button.

  -In the future, looking for a Bug icon in your toolbar, and then click the arrow next to it, then click on your project.

• Problem test on a real device - app does not start

  I use

  Eclipse 3.5 Galileo

  BlackBerry JDE 5.0

  BlackBerry Desktop Software 6.0.0.43

  a real device Curve 8900 with the software updated to 5.0.0.681.

  I read that Simulators have problems with Blackberry Maps. So, I wanted to test my application on the actual device to see if I've run into the same errors. Packaging and code-signing everything has worked well. I then installed the software on the device through Blackberry Desktop software. I found the icon in the downloads folder of the device but you cannot start the application. When I click on it nothing happens. No no error message, nothing, simply no reaction. So I have no idea what went wrong. Does anyone have an idea or suggestion how know what's the problem?

  I can start and run the program on the Simulator.

  Hi navad.

  I had the same problem a few days ago.

  Only the developed app one shows no reaction. all other things are working well.

  to me, helped the following:

  When the Blackberry is running, remove the battery and wait 2 minutes.

  Replace the battery and the blackberry again.

  After that, you should be able to run your application.

  I hope this will help.
