App does not work on the physical device

Hi, I just got word that my first submitted application does not work on any device - but gave the following error message:

"An error occurred when starting (AppName). The application has ended."

I tested my application and it worked perfectly for me on several simulators. I read a few similar posts on this forum, and I wonder if the problem is with code signing. So my question is this: do I have to sign my application again before each release, or that I only don't sign only once when, at the beginning?  Or the problem is maybe something else altogether?

Agree with RexDoug.

Your messge gives however to think that you do some long processingon the thread of events, for example, connect to a server as part of the start of the process and block the user interface until you get an answer.  This kind of thing is not in the Simulator, perhaps because it works in LAN connection speeds, so that blockages are still small.

  • Podcasts App does not work in the new mini iPad 2

    The Podcasts app does not work on my new iPad mini 2.  All other applications work OK. Typed on the results of the icon in an almost empty screen, with just a few shaded options along the bottom that do nothing.  There is a sign more in the upper left corner, tapping brings up the URL of the podcast application.

    I wonder if I should delete and reinstall the App (how?)

  • BlackBerry Webworks App does not work on the Simulator after conditioning

    Hi everyone, I ' ve developed a webworks app and everything works fine on the emulator ripple, but when I load it on the Blackberry (9860 and 9930) Simulator... it loads successfully (I can see the icon, etc.), but when I open it, appears only a WHITE SCREEN...!

    I thought it was the Blackberry Simulator, so I changed it (does not work)

  • Add the page button in PDF format does not work on the mobile device

    I created a button in my form that generates a new page. This new page has been defined as a model (Named 'New Page') and hidden (page 2). My button is on page 1 and uses a command script to execute a JavaScript script (on the mouse down) what follows is this script:


    var a = this.getTemplate ('new Page');

    a.Spawn ();

    Now, it works fine on my desktop. However, my problem is, I sent this form to myself, so I could fill it out on my phone. All of the s form other functions working perfectly, except the button to generate a page does not work. I am currently using an Android and view the PDF file on the application Acrobat from Adobe.

    Thank you

    I'm not aware of any mobile-based PDF Viewer that supports this method. Mobile versions of Adobe Reader supports a very limited subset of what support versions of office.

  • WebWorks app does not work on the device (openDatabase appeal fails)

    This has caused me a lot of grief, and I'm hoping to sum it up it here and find an answer.

    The app works well using Chrome and ripple. This application uses jQuery and jQuery Mobile and need to use a SQLite database. I read on the HTML5toGearsAPI is necessary if you want to support BBOS 5.0, which is included as well.

    When I insert the app on my torch (my physical device) it shows the splash screen and then some time screen. By adding some alert statements to each line in my document.ready function, I can say that the command open database is a failure.  I can't understand why. I feel I made some sort of mistake noobie stoopid.

    So here's the components of my html file and the command open on the javascript script.

        alert("after open");
    }
    

    You're not supposed to include things HTML5toGears when running on non - 5.0 devices? Is there a sort of call onError that I can use to get more details? It's really a problem, and I can't even to go beyond GO.

    Hi billfoust,

    I think that the reason is the recall of null. Remove it and I think it will solve your problems.

  • My web app does not work with the new version of firefox 31. It uses the heatmap.js for leaflet.js plugin to generate the plan of the temperature.

    There is heatmap.js site: http://www.patrick-wied.at/static/heatmapjs/example-heatmap-leaflet.html
    There example of layer of flyer.
    I could see after upgrading firefox to version 31 temperature map in the browser for this example. But with a previous version of firefox I could see it.

    My web app users leaflet.js and heatmap.js plugin. It users the same code as on the example page.
    After update firefox version saying "your script take too long to run. Continue? "again and again and not contains a temperature card.

    I use the folder plugin - 0.7.2.js and heatmap - 1.0.js for brochure.

    Seems to work here.

    You can try the following steps in case of problems with web pages:

    You can reload webpages and ignore the cache to refresh potentially stale or corrupt.

    • Hold down the SHIFT key and click the Reload button
    • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
    • Press 'Command + shift + R' (Mac)

    Clear the cache and cookies only from Web sites that are causing problems.

    "Clear the Cache":

    • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

    • Put yourself in the DEFAULT theme: Firefox/tools > Modules > appearance
    • Do NOT click on the reset button on the startup window Mode safe
  • Metro apps does not work after the withdrawal of the UAC GPO

    We use a GPO to disable UAC for the domain.  We then block this GPO to the OU where we put Windows 8 test machines and work apps UAC and metro very well. However, during testing, we found that if the GPO is applied (by putting the Win 8 box in a different OU), and then deleted (by putting the box 8 win in the test ORGANIZATIONAL unit), metro apps still don't work. they open and then close immediately, but the UAC seems to work as it should.  Then, we created an another GPO and applied to the test OR, which reverses more precisely the elements that we have changed for the GPO original, thinking that the original GPO changed something that was left in this state after the removal of the box to win 8 back into the test ORGANIZATIONAL unit.  Metro apps still don't work.  We have tried all the suggested methods found in other posts, but none works.  The app fix find some security issues and the "fixed", but which did not help either.  The keys that we change specifically in the GPO are:

    User account control: behavior of the guest of elevation for administrators in Admin Approval Mode, increase the value without asking confirmation

    User account control: detect application installations and ask the elevation, disabled

    User account control: only elevate UIAccess applications that are installed in safe places, select disabled

    User account control: turn the Admin Approval Mode, select disabled

    Any help for Metro applications to work again would be appreciated.

    Thanks, but I finally understood my problem.  It's a registry setting of GPO, not associated with UAC settings themselves.

  • Music app does not work when the screen is closed!

    Android6.0.1

    Compact Z5.

    When I listen to the music in the music of sony and closed the screen app, music will play a minute and stop, even when I turn the offshore endurance and add it to the white list, but it doesn't work.

    Other applications that can play music also encounter this problem. Some applications of music need wifi, they cannot work when the screen is too closed.

    What can I do about it?

    I think also ultra endurance disables many apps, so my guess is that you have a 3rd party app that close somehow your applications when the phone goes to sleep.

  • Why my music app does not work after the last update yesterday?

    WWhen by clicking on the app, it crashes just forever

    Well, I found a solution short term up to what Apple solves it on the next update of the firmware.

    1. double-click on the button of your home that opens your "tasks for applications Manager.

    2. close the music app.

    3. turn on "airplane Mode".

    4. click on in your music App

    5 turn off "airplane Mode".

    Do not close your music App (in the Manager of tasks for the apps) that he'll recover music App and you will have to start the entire process.

  • Acorn TV does not work on the new Apple TV

    So disappointed that the Acorn TV app does not work with the new Apple TV we just bought. We have subscribed on iTunes and nothing happens when you try to activate the software. We can look good on the MacBook, iPad and iPhone. Verified the purchase on iTunes account and that's fine. Contact Acorn and say it is a matter of Apple.

    Strange that I have to use Chrome to even write this question. Safari and hers do not work with the Support pages. I'll send in the comments.

  • Another "signed App does not work on device".

    Newbie here. I searched the forum and found a couple of previous posts with exactly the same problem as me, but could not see anything in the answers to help me once again. I have an app...

    1. BB 5.0 objectives.

    2. peripheral is BB Curve 9330 running 6.0.

    3 app had been successfully loaded twice before last week. (Works fine on Simulator 9330!)

    4. the app is fully signed.

    5 app is built in Eclipse Helios (Plugin 1.3.0 BB).

    6 tried to load in Eclipse with the two "Debug on the device' and 'load projects on the device. Same results, so be it.

    7. application appears in the download folder.

    8 click on download app does nothing.

    9 app does NOT appear in the list of Options/Applications of the device!

    10. I tried to look at the log of the events on the device but it's miles from the Greek for me.

    I'm dead in the water! Could use very little help, can someone point me to the definitive info on the loading of an application on a device? (I can live with debugging on the Simulator)

    Thank you!!!

    Glad to hear that you got running.

    It is possible to have two versions of the plug-in installed on the same computer.  They just need to be installed in separate Eclipse instances.  So, you can download the full installer from the link above and install some of costs.  Note that it comes with BlackBerry Java SDK 7.1, so you will need to use the update site to install the 5.0 version (instructions on this same page above).

    Just note that you can't use the same space to work in both versions of the plug-in.
