Another application already listening for application ID



In the simulator (and possibly the device, too, I did not try it) my application will automatically be executed at os boot.

I did not set up to automatically start my application in the configuration but it does.


My main method's class extends UiApplication and implemets PushApplication because I want the device to listen for push messages and deliver them to my application.


So I thought I will need to register my application for push messages via PushApplicationRegistry.


So in my main method, I call this code:




if (PushApplicationRegistry.getStatus(pad).getStatus() == PushApplicationStatus.STATUS_NOT_REGISTERED)

try {
} catch (IllegalArgumentException e) { System.out.println(e.getMessage());





With the debugger, I see that this code will be executed when the application will be executed at device startup and when I manually start the application via the application icon.


Is this the correct way to register for listening for pushes?


Because my application always runs into the catch with this message:

"Another application already listening for application ID XXXXXXXXX"


But...what's then the PushApplicationStatus I will have to check for?



What's a good method to check if the application has been executed programmatically (at startup) or manually?

Because if the application will always be executed at startup, i do not need to make an instance of the ui - i do only need the ui if the application will be executed manually.


Thanks in advance,



Best regards,

Re: Another application already listening for application ID

I got the answer to my last question, how to check if the application is executed at startup or manually:


It's done by


if (ApplicationManager.getApplicationManager().inStartup())



But for the other questions, I am still searching an answer.
