[amorosik]

I would like to make android apps to record phone call audio both outgoing and incoming calls
How to make a resident program that records the audio of phone calls, saves them on individual files, and allows you to reproduce them for listening?

Oh I understand, the beloved Aranzulla knows one more than the diablo
But what if I wanted to build it with code?

Eh ho capito, l'amatissimo Aranzulla ne sa una piu' del diablo
Ma se volessi farmela damme' a colpi di codice?

I meant that apparently it's still possible; how, unfortunately I don't know.
Intendevo dire che a quanto pare è ancora possibile; come, purtroppo non lo so.

Maybe I'll drink a coffee and try to find out.
Magari bevo un caffè (ancora da fare) e cercherò di informarmi.

I haven't looked at the source and I'm pretty sure it will contain a lot of bugs, non-existent libraries and methods (that's how Perplexity's big AI works ), but it might be a starting point.

Sub StopRecording
    ' Interruzione della registrazione

    recorder.Release()
End Sub

P.S.
Unknown type: mediarecorder - Are you missing a library reference?

I'm afraid you should attempt somersaults with inline Java.
