Hi Guys,
I am a newbie to android and was trying to get a simple recording
application up and running. However I am facing errors and wondering
if some of you can point me in the right direction.
Stack Trace:
03-02 17:27:53.415: ERROR/AudioRecord(224): Could not get audio input
for record source 1
03-02 17:27:53.425: ERROR/AudioRecord-JNI(224): Error creating

03-02 17:27:53.487: ERROR/AudioRecord(224): at

Sample Code:
// Create a new AudioRecord object to record the audio.
int bufferSize =
AudioRecord.getMinBufferSize(AUDIO_SAMPLE_FREQUENCY_8000HZ,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT);
AudioRecord audioRecord = new
AudioRecord(MediaRecorder.AudioSource.MIC,
AUDIO_SAMPLE_FREQUENCY_8000HZ,
AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT,
bufferSize);
audioRecord.startRecording();
AndroidManifest.xml:
...
<uses-permission android:name="android.permission.RECORD_AUDIO"></uses-
permission>
...
System Info:
Eclipse Galileo + SDK 2.1
IBM T60 running Windows XP
Thanks in advance,
Dmitriy
