I can call using below command to make a call:
"**adb shell am start -a android.intent.action.CALL 0000000000**"
and during the call, tried to mute and unmute microphone using the command:
"adb shell am start -a android.media.action.MICROPHONE_MUTE_CHANGED"
But, I got an error message that
"Error: Activity not started, unable to resolve Intent { act=android.media.action.MICROPHONE_MUTE_CHANGED flg=0x10000000 }"
Can I know how to fix it?
