Android Question DTMF

[new_danoptic]

I didnt find any recent info about DTMF recognition. But I found some DTMF decoders on GOOGLE PLAY.
Is there there a way to decode DTMF using B4X

Thanks

There is no API for this. There is also no reliable way to capture the incoming audio.
You might be able to capture the tones with the microphone and analyze them.
