Hi All,
I'm writing an Activity that attempts to use the AudioRecord API. When I
invoke the setNotificationMarkerPosition, my activity crashes with the
following error message:
*java.lang.IllegalStateException: Unable to retrieve AudioRecord pointer for
setPositionUpdatePeriod()*

The code snippet that triggers this bug is as follows:
AudioRecord audiorec = new AudioRecord(
MediaRecorder.AudioSource.MIC,
11025,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
11025*20);
//No exception is thrown and
audiorec seems to be valid
//THIS CALL CAUSES THE CRASH (THIS HAPPENS EVEN WHEN I PLACE THE LINE BELOW
THE NEXT SENTENCE
audiorec.setPositionNotificationPeriod(4000);
audiorec.setRecordPositionUpdateListener(new
AudioRecord.OnRecordPositionUpdateListener()
{
public void onMarkerReached(AudioRecord rec) {
;
}
public void onPeriodicNotification(AudioRecord rec) {
;
}
});
Thanks for anyone's help (my thirst for noetic stimulation has some limits
and I am giving up :) ).
PS: the above code also fails when I try different sampling rate, channel
configuration.
