I tried this code on a Samsung Galaxy S3:
package com.example.media_test;
import java.io.IOException;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v4.app.NavUtils;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MediaRecorder recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile("/mnt/sdcard/bla");
try {
recorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
long start = System.currentTimeMillis();
recorder.start(); // Recording is now started
try {
Thread.sleep(500);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
recorder.stop();
long end = System.currentTimeMillis();
System.out.println("cost : " + (end - start));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
The cost was only 833, and that's with 500 ms of sleep. Seems reasonable.
Maybe you need a better phone?
Also, remember to have these permissions:
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
