DTMF Android App

Adapt or change the Github "pjasiun" project to have it working with a new set of frequencies. It is, the new set should be the frequencies of the original DTMF tones, multiplied by 14. It is named as M-DTMF. There are the specifications:

M-DTFM set of lower frequencies (9758 Hz, 10780 Hz, 11928 Hz, 13174 Hz)

M-DTFM Set of upper frequencies (16926 Hz, 18704 Hz, 20678 Hz, 22862 Hz).

Modified M-DTMF tones correspond to the frequencies of the original DTMF tones, multiplied by 14.

The final delivery will be a very basic Android App using the M-DTFM code, as previous description. The app must run in the background and display the received numbers on screen.

If the M-DTMF audio pickup by microphone matches the pre-recorded number stored in a table at program memory, then the software should issue an alert.
