Hej, im currently trying to get AudioRecord to work. Because I need it
in a bigger project. But it seems to mess up a lot. I have been trying
alot of things, so I went back to basic when I traced this bug.
I am using my Samsung Galaxy S as my debug-device.
My problem is, first time after a reboot of my device I can initialize
the AudioRecord object I create without problems. But the second time
I run it, it won't initialize the AudioRecord object. I have tried
several frequencies, fyi.
Here is my code:
package android.audiorecordtest;
import android.app.Activity;
import android.media.AudioFormat;
import android.media.AudioRecord;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class AudioRecordTest extends Activity {
int frequency;
AudioRecord audRec;
TextView txtVw;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtVw = (TextView) findViewById(R.id.txtVw);
frequency=8000;
int bufferSize=(AudioRecord.getMinBufferSize(frequency,
AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT))*2;
if (bufferSize>0) {
audRec = new AudioRecord(MediaRecorder.AudioSource.MIC,
frequency, AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT, bufferSize);
int status = audRec.getState();
if (status == AudioRecord.STATE_INITIALIZED) {
txtVw.setText("Initialized" + frequency);
} else {
txtVw.setText("Not Initialized i=" + frequency);
}
}
}
