Hi guys

the code below does not work on Android 9.
The error appears:
java.lang.RuntimeException: java.lang.IllegalAccessException: void android.os.SystemProperties.<init>() is not accessible from java.lang.Class<anywheresoftware.b4a.agraham.reflection.Reflection>

Can anyone help me?

B4X:
Sub GetManufacturerSerialNumber As String
    Dim sn As String
    Dim r As Reflector
    Dim m As Object
    Dim Types(1) As String

    Types(0) = "java.lang.String"
    r.target = r.CreateObject("android.os.SystemProperties")

    m = r.GetMethod("get", Types)
    sn = r.InvokeMethod(r.Target,m,Array("ril.serialnumber"))
   
    Return sn
End Sub
Thank you!
Mennea
