  • Error preverifying class java during build (BlackBerry)

    - by Davide Vosti
    I'm trying do build and debug a small project for BlackBerry. During the build I'm getting this error Error preverifying class java ... I read on the net this error could be caused by referencing multiple projects but I tried to move every package in a single project but the error is still there. I tried with multiple JDE version (currently 4.7) and the Java compiler is set to 1.6. Eclipse version is 3.4.1 as recommended by RIM's documentations. Does someone have some clue?

  • BlackBerry responseXML is null

    - by Andrew
    I'm trying to port a portion of AJAX code I wrote over to the BlackBerry application's embedded browser. Our base build is 4.6.1 and the RIM documentation claims that XMLHttpRequest's responseXML is available starting with this version. And when I request an XML file from my local server, I get back the responseText (so I know the request is working), but the responseXML is always null. I've made sure the HTTP "Content-Type" header is set to "text/xml" and I am getting the correct data loaded in a web browser. It's just nulling out in the BB web environment. Does anyone know what might be happening? A backup of using the responseText and piping it through DOMParser is not possible because that object was not added to the BB browser until 4.7.1. So I'm not sure what fallback I have.

  • Deploying BlackBerry Applications Across Environments

    - by sethxian
    Has anyone come up with a good solution for deploying BlackBerry applications across different environments? My example is storing URLs and Authentication information in code. In most cases, a developer is going to have a different set of URL's to test against when developing the application vs what the end user is going to hit. The idea is when I go to build for production, I have something swap out the environment settings for the target environment vs manually replacing environment specific code each time. I am currently using eclipse. The only thought I've come up with so far would be to use a resource with encrypted values and have that swap when I run my build. Any ideas?

I would like to add Radio button (which is ChoiceGroup in BB) also into the screen.

Can't i add ChoiceGroup into Vertical Manager. If i use VerticalManager and adding many fields and would like to add Radio button also into it, How do i do that? Pleaes give your advise. Thanks.

    - by Vivart
    in my blackberry application i have to create a effect in which fullscreen bitmap is slowly disappearing and ui screen is coming up. protected void paint(Graphics g) { g.setGlobalAlpha(globalAlpha);//starting value of globalAlpha is 255. g.drawBitmap(0, 0, getWidth(), getHeight(), _bitmap, 0, 0); g.setGlobalAlpha(255 - globalAlpha); globalAlpha--; super.paint(g); } This code is just for giving demo that what i want. super.paint(g) is calling 255 times because of that its a poor code. in one timer task i am calling invalidate(); So any suggestions how to implement this?

  • Bundling images with Blackberry

    - by Casebash
    How do I get bundled images with the BlackBerry Eclipse Plugin 1.1 Beta? I copied an image into "res/background.jpg" and tried to load it using Bitmap.getBitmapResource on background.jpg. Unfortunately, the image wasn't found (Illegal argument exception). I tried moving my image file into the src folder as per the advice here, but that didn't work either. I have opened up the .jar file and the background image is present at the root of the .jar file. The option to convert image files to .png isn't selected either. Links Could not find sample Library Reference

  • In Blackberry's Application class what is the difference between hasEventThread() and isHandlingEven

    - by Eric Sniff
    In Blackberry's Application class what is the difference between hasEventThread() and isHandlingEvents(). I'm just curious, because I have only found hasEventThread useful. From BB's docs for Applicaiton: public boolean hasEventThread() Determines if this application has entered the event dispatcher. Returns: True if this application has entered the event dispatcher (i.e. has invoked Application.enterEventDispatcher()); otherwise, false. isHandlingEvents public final boolean isHandlingEvents() Determines if this application has entered the event dispatch loop. Returns: True if the application has entered the event dispatch loop; otherwise, false. My only guess is that isHandlingEvents most happen sometime after hasEventThread. But is that really that useful?

  • In Blackberry, how are shared objects in runtimestore recognized by other applications

    - by Carbonizer
    In Blackberry Runtime Store, when sharing objects between applications. How can we call methods of the shared object in another application, if the object itself is not recognized in the other application ? i am getting a runtime error when object gets typecasted, as that object is not defined in the calling applicatoin . If i typecast it to super interface and have the interface in another application. When i call getClass() on the object returned from the runtimestore. It shows as concrete class instance stored in the RunTimeStore. How can a share a object in runtimestore and use it across different applications ?

  • Ad-hoc connection between iPhone and Macbook Pro

    - by Phil Nash
    I sometimes find it useful to connect my iPhone to my Macbook Pro by creating an ad-hoc wireless network from the MBP and connecting to that from the iPhone. However, what I find is that sometimes this works and sometimes it doesn't. When it's not working the symptoms are usually that I see the ad-hoc SSID in the list of available networks on the iPhone, can connect to it from there (including entering my WEP key), and it shows up as the wifi network in use. However I don't get the wifi symbol in the taskbar (it remains as 3G) and attempting to use the connection (e.g. trying to connect to iTunes or Keynote using their respective Remote apps) fails saying that there is so wifi connection. I've tried rebooting both the iPhone and the MBP, recreating networks with different SSIDs and tried different channels - all to no avail! I'm especially puzzled that (a) sometimes it works just fine first time and (b) the Settings app seems to think its all connected fine. Is there anything else I should be trying?

  • Blackberry stopwatch implementation

    - by Michaela
    I'm trying to write a blackberry app that is basically a stopwatch, and displays lap times. First, I'm not sure I'm implementing the stopwatch functionality in the most optimal way. I have a LabelField (_myLabel) that displays the 'clock' - starting at 00:00. Then you hit the start button and every second the _myLabel field gets updated with how many seconds have past since the last update (should only ever increment by 1, but sometimes there is a delay and it will skip a number). I just can't think of a different way to do it - and I am new to GUI development and threads so I guess that's why. EDIT: Here is what calls the stopwatch: _timer = new Timer(); _timer.schedule(new MyTimerTask(), 250, 250); And here is the TimerTask: class MyTimerTask extends TimerTask { long currentTime; long startTime = System.currentTimeMillis(); public void run() { synchronized (Application.getEventLock()) { currentTime = System.currentTimeMillis(); long diff = currentTime - startTime; long min = diff / 60000; long sec = (diff % 60000) / 1000; String minStr = new Long(min).toString(); String secStr = new Long(sec).toString(); if (min < 10) minStr = "0" + minStr; if (sec < 10) secStr = "0" + secStr; _myLabel.setText(minStr + ":" + secStr); timerDisplay.deleteAll(); timerDisplay.add(_timerLabel); } } } Anyway when you stop the stopwatch it updates a historical table of lap time data. When this list gets long, the timer starts to degrade. If you try to scroll, then it gets really bad. Is there a better way to implement my stopwatch?

  • Windows 7 Not Recognizing Camera Nor iPhone as Camera

    - by taudep
    I've been struggling with this one for a few days. I've recently upgraded an older computer to Windows 7 Home Premium. Neither my digital camera (A Canon SD1200IS) nor iPhone are ever detected as cameras, nor ever show up as accessable in Explorer. With the Canon camera, no driver is required. It's supposed to work with the default Windows 7 drivers. However, in the Control Panel's Device Manager, I'm always seeing a yellow icon next to the "Canon Digital Camera" device. I've uninstalled the device and let Windows attempt to reinstall, but it can never find a driver to install. With the iPhone, it's very similar. One big difference, though, is that iTunes can see the iPhone and back it up, etc. However, again when I go to the Device Manager, there's a yellow icon next to the iPhone. I've uninstalled iTunes, reinstalled, rebooted, deleted drivers, and let Window try to reinstall the driver, but it can never find the driver. So there seems to be some correlation that my machine can't detect cameras properly, and that it might be even a lower-level type of driver I'm struggling with. I know that USB however, does work, because I have have an external drive hooked into the machine. I've gone through the web and tried two hours worth of fixes, without success. I feel like if I can get the Canon camera detected, then the iPhone will be on it's way to being fixed too. BTW, I couldn't really find anything of use in the Event viewer. Any and all suggestions welcome.

  • iPhone VPN with OpenSwan fails to reconnect

    - by gilm
    I have managed to configure VPN with iPhone and OpenSWAN on Linux 2.6. Though, when disconnecting the iphone and reconnecting, it times out. I have found that: 1) no packets are being sent when you disconnect iPhone from VPN. 2) when reconnecting, pluto picks up on the older socket and tries to use that state machine. which then fails and iPhone retransmits until times out. I'm using the latest version in git, including #1204 patch. I see the NAT-T patch debug lines in the logs. But still, no cookie. Help?

  • Starting one BlackBerry screen from another.

    - by DanG
    I've recently run into a snag while putting on the finishing touches for my BlackBerry app. I'm building a login screen which, if the user is successful in logging in, goes to a data loading screen, and then to a home screen. From the home screen, you can use the app. Everything works great but one thing, I can't seamlessly move from the login screen to the loading screen, to the home screen. I can move from the login screen to the loading screen ok, because I'm doing that via a button click which is on the GUI thread, but then I have the login screen at the bottom of the stack and can't get it out using the dismiss method. Once in the loading screen, I can't push the home screen because I'm not doing it via the gui method, though I'm able to update the GUI via the following piece of code: private void checkData(){ Timer loadingTimer = new Timer(); TimerTask loadingTask = new TimerTask() { public void run() { // set the progress bar progressGaugeField.setValue(DataManager.getDataLoaded()); // for repainting the screen invalidate(); } }; loadingTimer.scheduleAtFixedRate(loadingTask, 500, 500); } Does anyone know how to solve my problem of moving seamlessly from the login screen to the loading screen to the home screen? Note: once I'm at the home screen I'd like to have it be the only screen on the stack. Thanks!

  • iPhone Cannot log into WiFi suddenly [closed]

    - by Stanley
    I suddenly get into this strange problem. My iPhone has been using the WiFi setup at my home for more than a year. Suddenly it cannot connect to the internet despite still having the full WiFi signal icon. Have an older iPhone 3 GS and it can still browse the net using the same WiFi. So the wireless router should be working. When I check the non-functioning iPhone, it has the "Router" and the "DNS" entries blank while the functioning iPhone has entries on both of the fields. Also the subnet Mask are different. Please help.

  • iPhone doesn't save password for Cisco IPsec VPN using racoon daemon

    - by dsx
    On my Debian server I had set up racoon daemon (1:0.8.0-14) for Cisco IPSec VPN using certificates for authentication. My racoon.conf is like following: log info; path certificate "/etc/racoon/certs"; listen { isakmp $SERVER_IP_HERE [500]; isakmp_natt $SERVER_IP_HERE [4500]; } timer { natt_keepalive 10 sec; } remote anonymous { lifetime time 24 hours; proposal_check obey; passive on; exchange_mode aggressive,main; my_identifier asn1dn; peers_identifier asn1dn; verify_identifier on; certificate_type x509 "cert_name.crt" "key_name.key"; ca_type x509 "ca.crt"; mode_cfg on; verify_cert on; ike_frag on; generate_policy on; nat_traversal on; dpd_delay 20; proposal { encryption_algorithm aes; hash_algorithm sha1; authentication_method xauth_rsa_server; dh_group modp1024; } } mode_cfg { conf_source local; auth_source system; auth_throttle 3; save_passwd on; dns4 8.8.8.8; network4 $SOME_LAN_SUBNET; netmask4 255.255.255.0; pool_size 128; } sainfo anonymous { pfs_group 2; lifetime time 24 hour; encryption_algorithm aes; authentication_algorithm hmac_sha1; compression_algorithm deflate; } I'm not using PSK authentication here. Using iPhone configuration utility I had uploaded all required certificates to iPhone and set up VPN on demand. Everything works just fine except one thing: iPhone refuses to save VPN password regardless of save_passwd on; in racoon configuration file. As opposed to iPhone behaviour, Mac OS X 10.8.2 have no problems saving password. I had examined iPhone log file and found following: racoon[151] <Notice>: >>>>> phase change status = phase 1 established configd[50] <Notice>: IPSec Network Configuration started. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-ADDRESS = $SUBNET_IP_HERE. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-MASK = 255.255.255.0. configd[50] <Notice>: IPSec Network Configuration: SAVE-PASSWORD = 0. configd[50] <Notice>: IPSec Network Configuration: INTERNAL-IP4-DNS = 8.8.8.8. configd[50] <Notice>: IPSec Network Configuration: BANNER = . configd[50] <Notice>: IPSec Network Configuration: DEF-DOMAIN = . configd[50] <Notice>: IPSec Network Configuration: DEFAULT-ROUTE = local-address $SUBNET_IP_HERE/32. configd[50] <Notice>: IPSec Phase2 starting. configd[50] <Notice>: IPSec Network Configuration established. configd[50] <Notice>: IPSec Phase1 established. Please note IPSec Network Configuration message containing SAVE-PASSWORD = 0.. Is it a bug in racoon daemon on server, or iPhone (iOS version is 6.0.1 (10A523)) or it is me missing something? How to make iPhone remember IPSec VPN password?

Following is my code : BFcontacts = new ButtonField("Cnt") { protected void paint(Graphics graphics) { //Bitmap contactsbitmap = Bitmap.getBitmapResource("contacts.jpg"); //graphics.drawBitmap(0, 0, contactsbitmap.getWidth(), contactsbitmap.getHeight(), contactsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Cnt",0,0); } }; BFcontacts.setMargin(305,0,0,10);//vertical pos,0,0,horizontal pos HFM.add(BFcontacts); BFmsg = new ButtonField("Msgs") { protected void paint(Graphics graphics) { //Bitmap msgsbitmap = Bitmap.getBitmapResource("messages.jpg"); //graphics.drawBitmap(0, 0, msgsbitmap.getWidth(), msgsbitmap.getHeight(), msgsbitmap, 0, 0); graphics.setColor(Color.WHITE); graphics.drawText("Msgs",0,0); } }; BFmsg.setMargin(305,0,0,40);//vertical pos,0,0,horizontal pos : original HFM.add(BFmsg); add(HFM) Thanks in advance

  • blackberry implement audio player

    - by Prasad
    Hi, I am developing an application which let users to hear songs online. And I used Blackberry Player and Manager APIs. My application works fine and I can play songs. Now I wan't to add more controls to it. As an example I want pause, play songs. Mute the sound, Control the volume. Display the progress of the play back. Display the current time position of the song like that. I started research on that. And I tried to do that with PlayerListener. But unfortunately all the time I am getting IllegalStateException. So I can't go ahead with that research. As a help can someone please tell me how can I implement above kind of controls for a player. Appreciate if someone can post a sample code to do that. Further I will put my playback source code here. public void run() { try { p = Manager.createPlayer(requestedSong + SystemSettings.strNetwork); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } public void run() { try { p = Manager.createPlayer(strSongURL); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } Thank you very much.

  • Designing secure consumer blackberry application

    - by Kiran Kuppa
    I am evaluating a requirement for a consumer blackberry application that places high premium on security of user's data. Seems like it is an insurance company. Here are my ideas on how I could go about it. I am sure this would be useful for others who are looking for similar stuff Force the user to use device password. (I am guessing that this would be possible - though not checked it yet). Application can request notifications when the device is about to be locked and just after it has been unlocked. Encryption of application specific data can be managed at those times. Application data would be encrypted with user's password. User's credentials would be encrypted with device password. Remote backup of the data could be done over HTTPS (any better ideas are appreciated) Questions: What if the user forgets his device password. If the user forgets his application password, what is the best and secure way to reset the password? If the user losses the phone, remote backup must be done and the application data must be cleaned up. I have some ideas on how to achieve (3) and shall share them. There must be an off-line verification of the user's identity and the administrator must provide a channel using which the user must be able to send command to the device to perform the wiping of application data. The idea is that the user is ALWAYS in control of his data. Without the user's consent, even the admin must not be able to do activities such as cleaning up the data. In the above scheme of things, it appears as if the user's password need not be sent over the air to server. Am I correct? Thanks, --Kiran Kumar

  • encode divx into mpg4 (iphone compatible)

    is there a way to encode (?) a divx file into an mpg4 file or something that will play on the iphone, but while the divx is downloading/streaming. And if possible is it possible to encode on the fly so the divx file gets encoded into an iphone compatible format and then streamed to a iphone with like a 2 minute or so delay, all while the divx file is still downloading.
