[android-developers] Re: AudioRecord can't get any notification when record/marker position updated
Hello Steven_T ,
Can you tell me how you able to fix this issue?.
I am also not getting onMarkerReached callback.
Is there any limitation for setNotificationMarkerPosition.

OK, so it sounds like audio is being produced by the kernel driver.
I just looked at your code, and I think you need to call read() once
to pass in your first input buffer.

thank you for reply!
I didn't disable audio input in avd
what you means is use option -audio backend to set an audio input
I had used the next code test audio input
//
Intent intent = new Intent

startActivityForResult(intent, ACTIVITY_RECORD_SOUND);

it can recording and saved audio as a file named recording47845.3gpp
