I can use Try-Catch to handle LastException. Can we catch different type of exceptions based on third party library when using JavaObject?
For now,
LastException returns:
LastException.Message return:
Can we have something like this? Is this make B4X more complicated?
Java sample code:
Maybe there is another way to parse the error message.
Let say I only want to show the final part without showing the java class.
For now,
LastException returns:
B4X:
(ResourceNotFoundException) org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'test2.vm'LastException.Message return:
B4X:
org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource 'test2.vm'Can we have something like this? Is this make B4X more complicated?
B4X:
Public Sub putTemplate (tf As String)
Try
template = velocity.RunMethod("getTemplate", Array(tf))
Catch (ResourceNotFoundException)
Log(ResourceNotFoundException.Message)
Catch (ParseErrorException)
Log(ParseErrorException.Message)
Catch (MethodInvocationException)
Log(MethodInvocationException.Message)
Catch (Exception)
Log(Exception.Message)
End Try
