Buildozer setup for audio

[Vivek Koppikar]

How can I appropriately setup buldozer.spec so i can capture audio from the mic on android phones.

Appreciate any help!

Cheers

I missed adding that I intend to use pyjunius so I can call java classes for audio

Gave it a try:
Here is my code in Pythin, KIvyMD and pyjunius...
The app crashes as soon as def record() is run.. ie after I hit the to record button

from kivy.lang import Builder
from kivymd.app import MDApp
from jnius import autoclass
from time import sleep

kv = '''
Screen:
    MDCard:
        size_hint: None, None
        size: root.size
        pos_hint: {"center_x":0.5, "center_y": .5}
        elevation: 10
        padding: 25
        spacing: 25
        orientation: "vertical"

        MDLabel:
            id: is_recording
            text: "Not recording"
            font_size: 50
            halign: "center"
       
        MDRoundFlatButton:
            text: "Record"
            font_size: 40
            pos_hint: {"center_x": 0.5}
            on_press: app.record()

        MDRoundFlatButton:
            text: "Stop"
            font_size: 40

        return Builder.load_string(kv)
        #return Builder.load_file('./mainscreen.kv')
   
    def record(self):
        self.root.ids.is_recording.text = f"Recording"


        # get the needed Java classes
        MediaRecorder = autoclass('android.media.MediaRecorder')

        OutputFormat = autoclass('android.media.MediaRecorder$OutputFormat')
        AudioEncoder = autoclass('android.media.MediaRecorder$AudioEncoder')

        # create out recorder
        mRecorder = MediaRecorder()
        mRecorder.setAudioSource(AudioSource.MIC)
        mRecorder.setOutputFormat(OutputFormat.THREE_GPP)
        mRecorder.setOutputFile('/sdcard/testrecorder.3gp')
        mRecorder.setAudioEncoder(AudioEncoder.AMR_NB)

        # record 5 seconds
        mRecorder.start()
        sleep(5)
        mRecorder.stop()
        mRecorder.release()

    def stop(self):

if __name__ == "__main__":
    MyApp().run()

And probably unrelated, sleep() will stall the Kivy event loop. Use Clock, or sleep() in a thread.
