Error with scan barcode

[Poonam Sharma]

Hi 

This is my code to scan Barcode  for android phone. In Rho Simulator, I am getting this error :

GET http://127.0.0.1:34492/app/FrmMain/ScannerCall 500 (Server error) 

Code :

 def ScannerCall

    Alert.show_popup('Alert1')

    Rho::Barcode.take({}, url_for(:action => :scan_received))

  end

  

  def scan_received

    Alert.show_popup('Alert2')   

    # If status is not 'ok', the scan was cancelled

    if @params["status"] == "ok"

      Alert.show_popup('Alert3')

      #Rho::Log.info(@params["barcode"],"Barcode result")

    else

      Alert.show_popup('Alert4')

      #Rho::Log.info("Cancelled", "Barcode result")

    end

  end

Thanks,

Poonam
