I tried this example:

I didn't modify anything in it but when I press "btnStartRecording" the app shows me a Msgbox telling me that I can't use an uninitialized object. This is mistake:
Error:
Logger connesso a:  HUAWEI COL-L29
--------- beginning of system
--------- beginning of main
PlaybackComplete

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
How I can resolve it?
