Apps Error recording audio using native AudioRecord interface

[martinb]

Hi!

Has anyone been able to record audio using the native AudioRecord interface? I'm trying to do this on my Neo Freerunner but all I get in logcat is:

I/AudioHardwareALSA( 787): Initialized ALSA CAPTURE device AndroidRecord_Microphone
D/AudioHardwareALSA( 787): Set CAPTURE PCM format to S16_LE (Signed 16 bit Little Endian)
D/AudioHardwareALSA( 787): Using 1 channel for CAPTURE.
D/AudioHardwareALSA( 787): Set CAPTURE sample rate to 8000 HZ
E/AudioFlinger( 787): Error reading audio input
W/AudioRecord( 947): obtainBuffer timed out (is the CPU pegged?) user=00000000, server=00000000

The android::AudioRecord::read() function returns the number of bytes I'm trying to read, but the resulting buffer is filled with zeroes.

Any idea or input would be helpful. Thank you.

I had a similar problem, I ended up having to set the user permission

in the android manifest xml add

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

under the manifest tag
