Need some help to analyze what the problem can be? Have got a couple of crash errors during the last month.
Error code: org.apache.harmony.xml.ExpatParser$ParseException

Thanks, do you have any suggestion how to catch this and e.g. give an exception handling action before it cause a clossure of the program?

You could put a TRY...CATCH, like this (in pseudo-code):
B4X: 
Try

<grab XML>

Catch

Error, cannot get XML

End Try

That way your app doesn't end but notifies the user something went wrong.

Thanks, I am not able to recreate the error, can only get the error report at the google play developer consol. It could be some of the files that can be downloaded that are corrupt. There are 84 possible to choose from in the app and they are updated daily so I have to keep on trying to get an error myself. The statistics shows about 1 error in 1000 requests so it should not be impossible but will take time.http://www.b4x.com/forum/images/smilies/frown.gif
