Make sure you're using 16 bit samples. 8 bit samples seem to just not work. Don't use the default anythings - actually set it to MIC, PCM_16BIT, 11025, MONO. Then once that works you can try tweaking other options. Also, make sure your buffer is big enough - you can use AudioRecord.getMinBufferSize to set up your recorder with a value with minimal latency.
The way AudioRecord fails is really gross and uninformative. Hopefully they'll fix that (and 8-bit recording) before 1.5 final...
