Reflector issues on views -- Need Help

[Indigoo]

Hi,

Im currently the current fonctions below and i am having an issue depending which version the phone is.

Ive tested the following function on 2 different phones:

Sub SetOpacity(alpha As float, aView As View)
    Dim aReflector As Reflector
   aReflector.Target = aView
   aReflector.RunMethod2("setAlpha", alpha, "java.lang.float")
End Sub

#1: Version 4.1.1 with API 10 - 15 -17 and it works perfect

#2: Version 2.3.5 with API 10 - 15 -17 and i get the error message below

Can anyone help me out?

aReflector.RunMethod2("setAlpha", alpha, "java.lang.int")
java.lang.NoSuchMethodException: setAlpha

That is expected. setAlpha was added in API 11, Honeycomb 3.0.x. The 2.3.5 device doesn't implement it.

Thanks a lot for the quick answer.
Do you know if there is a way to work around that?

Not that I know of, but then I don't really do GUI stuff so someone else might have an idea.
