I think I found my problem.
First - the AudioRecord only seems to work for this combination of
parameters:
ar_test = new AudioRecord(MediaRecorder.AudioSource.MIC, 8000,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, 100000);
(buffer size must be > 4096 apparently)
and Second - you must have permission for RECORD_AUDIO set in
manifest
Onward and upward...
