For MonoTouch Console.WriteLine will appear in MonoDevelop and in the logs from your iOS device.
For MonoDroid, you can use the Android.Util.Log class to register debugging, information, errors, etc., which you can view using the Android Debug Bridge logarithm (adb logcat). An example would be such an announcement for an informational message: Android.Util.Log.Info ("Barcode", "Scan button pressed.")
