Audiorecord in Android mobile matlab Application

Hi. I would like to know whether there is a way to use mobile record in matlab Android Application. I tried to call 'recObj = audiorecorder(44100,8,1)' but, it could not find audio input device in Galaxy Note 8. I tried audiodevinfo, but it also cannot input dev. I checked App's permission in Setting System APP. Then it doesn't have audio mic Permission(there are no checkable box, I think this app doesn't consider mic)

Finally, I'd like to make a program which do real time record and make a spectrogram graph. Could you teach me?

Thank you.

At the MATLAB level, without Simulink, the support is for Android sensors, and those do no include the microphone.
