Android Question Crash on setLastException.

[Robert Valentino]

I got a crash report today from a user. Is this crash implying that I crashed on a setLastException??

Running v10.2

What are you doing in:

BOBsCommon.ct8textsize._checksize

?

 

[Robert Valentino]

Private Sub CheckSize(TargetView As Object, MultipleLines As Boolean, NumLines As Int) As Boolean
            
            Try
                   If  TargetView = Null Then 
                    Log("SingleLineNoLargerAndPadding")
                          Return True
                   End If
            Catch
                Log("SingleLineNoLargerAndPadding")
                      Return True
            End Try

            Dim lbl As Label = TargetView
            
            Try
                If  MultipleLines Then
                    Dim txtHeight As Int = su.MeasureMultilineTextHeight(lbl, lbl.Text)
                
                    If  NumLines > 0 Then
#if DebugX                    
                        Log("NumLines:" &NumLines &"  txtHeight:" &txtHeight &"  lbl.Height:" &lbl.Height &"  EachLine:" &(lbl.Height / NumLines) &"  TextSize:" &lbl.TextSize)
#end if
                    
                        If  txtHeight <= lbl.Height Or (lbl.Height / NumLines) >= txtHeight Then 
                            Return True
                        End If
                        
                        Return False
                    Else
                        If  txtHeight > lbl.Height Then 
                            Return False
                        End If
                    
                        Return True
                    End If
                Else
                    If  cvs.MeasureStringWidth(lbl.Text, lbl.Typeface, lbl.TextSize) > lbl.Width     Or _
                        su.MeasureMultilineTextHeight(lbl, lbl.Text) > lbl.Height Then 
                        Return False
                    End If
                
                    Return True
                End If
            Catch
                Return False
            End Try
End Sub

Seems to be the highlighted line. But I check for null when I first enter the routine

I think that it is better to remove these Try / Catch blocks. Seems like they are hiding the real problem.

Will do
