Finally I was able to find the SOLUTION
the AudioComponent works correctly on Android, but you have to enable the options within the APP.
I mean you go to the microphone option and activate it.
In my case activate all, because I am using an emulator called LDPlayer with a webcam.
I leave some example images of the LDplayer emulator, it should be similar on any mobile device.
I will remain as a task, find out how to put that option by default, when I find out I will come back to comment here.
For now I leave this as the solution.
emulator link.
