Turn loudspeaker on android 4.4 KitKat and above

Can you turn the loudspeaker on this adroid version ?

For previous versions the code below works perfect :
I use it together with phone events to rise the following code .

Code:

  Dim rr As Reflector
        rr.Target = rr.GetContext
        rr.Target = rr.RunMethod2("getSystemService", "audio", "java.lang.String")            
        rr.RunMethod2("setMode", "2", "java.lang.int")
        rr.RunMethod2("setSpeakerphoneOn", True, "java.lang.boolean")  

Thank you .
