Java Question ba.raiseEvent not firing...

[DevBaby]

I have used the ba.raiseEvent from a library before with success. However this time the code executes (no errors) but nothing happens.

I am using an @ActivityOjbect for the first time, I am not sure if this has anything to do with it.

Are you trying to raise an event from the main UI thread or from within another thread?
If you're trying to raise an event from within another thread then you need to use the syntax:

ba.raiseEventFromDifferentThread(Sender instance here, null, ATaskId, EventName here, true, new Object[] { Your values });

The Boolean parameter (true in this example) tells raiseEventFromDifferentThread whether to raise an exception if the event Sub does not exist.
That's another obvious thing to check - whether the event Sub exists - check that whether or not you're raising an event from the main UI thread.
When you initialize the object do you convert the event name parameter to lower case?
Try logging the complete eventname that you're raising to see exactly what Sub it's trying to call.

Hi,

I am not sure what thread I am trying to raise the event from (Main UI vs. another).

When I use ba.raiseEventFromDifferentThread(Sender instance here, null, ATaskId, EventName here, true, new Object[] { Your values });, I get the exception thrown for a missing event, but I definitely have the event included in the main module of B4A.

Please post the code.

Thanks for your help, the code is below. For easy reference, the call private void showfeed is at the bottom of the sdk code block. I am also using an AsyncFacebookRunner asyncRunner; to run the calls on a separate thread.


B4A event code...

Sub fbfeedcomplete(answer As String)

   Msgbox("feed complete","msg")

1. Sub names are always lower case.
2. Usually you should use an EventName variable as a prefix for the event.

ba.raiseEvent(this, eventName + "_" + fberror", ferror.toString())

eventName should also be lower cased.

This worked! Thanks to you both, Erel and Warwound, for your help with this.
