this is my code :
Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

    Private btnBuy As Button
    Private btnGo As Button
    Dim manager As BillingManager3
    Private key As String = "MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAtKs+EKiUgwa4K+GxeBZp5FeD5pmb1R/JsOLLSu54zcugEHb445qM1tfvvO+Tmd+WkGVDYi8smi8M40W2X/93XrRg4y9TDh5dUrZxrM9JF7nkta8Jn3zmrCDZYnFHTxSKMWCcMmmUnop+uDCZY7aZ8+V3xvSIsWqQ26icdHCdV57zUWisLmZurwOyWGTzgg0wavuYcdP3lyhdXjkI9J11Ws6UzCrbY4KztXllAdaVlnuRNd+LKMvW7MopLU6Y8Q1znajAVYDUswP2As8du2HXUyp4hIYNLpuoLdCDKEBjNnI53VV2y30Ld7ecML40pDEI4hCz7mOWCTWMaVyn1dV29wIDAQAB"

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:

    If FirstTime Then
      manager.Initialize("manager", key)
      manager.DebugLogging = True
