Android Question Try Catch - Error message

[joilts]

Hi to everyone.

I'm having trouble with this code:

Public Sub recognizePlateChar(dir As String, fileName As String, extension As String) As String
        NativeMe.InitializeContext
        File.Copy(dir,fileName&extension,global.dir, "1_"&fileName&extension)
        Dim retStr As String = ""
        Dim path As String = global.dir
        Dim name As String = "/1_"&fileName
        retStr = NativeMe.RunMethod("getPlate",  Array (path,name,extension,global.dir))
        Log(retStr)
        retStr = returnPlate(retStr)
        Log(retStr)
        Return(retStr)
End Sub

Running on a 4.1.1 (API 16) emulator I get this error message:

An error has occurred in sub: ocr_functions (java line:103) java.lang.reflect.InvocationTargetException

Tried to change for this code (inserting a try catch):

Public Sub recognizePlateChar(dir As String, fileName As String, extension As String) As String
Try
        NativeMe.InitializeContext
        File.Copy(dir,fileName&extension,global.dir, "1_"&fileName&extension)
        Dim retStr As String = ""
        Dim path As String = global.dir
        Dim name As String = "/1_"&fileName
        retStr = NativeMe.RunMethod("getPlate",  Array (path,name,extension,global.dir))
        Log(retStr)
        retStr = returnPlate(retStr)
        Log(retStr)
        Return(retStr)
Catch
    Return("")
End Try
End Sub

The error message now is:

An error has occurred in sub: ocr_functions (java line:115) java.lang.ClassCastException: java.lang.ExceptionInInitializerError
cannot be cast to java.lang.Execption

Is there a way to fix the ClassCastException when using Try Catch structure?

Running the original code on a Nexus 5 (Android 6) and Galaxy S4 (Android 5), got no errors.

Thanks for your attention.

Wrap your Try/Catch block in another Try/Catch block.
