Android Multimedia How to capture audio in an android application?

This snippet captures audio from a given source and saves it to a file with android.media.MediaRecorder. 

/* Create a MediaRecorder */

recorder = new MediaRecorder();

/* ContentValues include title, timestamp, mime type */

ContentValues values = new ContentValues(3);

values.put(MediaStore.MediaColumns.TITLE, SOME_NAME_HERE);

values.put(MediaStore.MediaColumns.TIMESTAMP, System.currentTimeMillis());

values.put(MediaStore.MediaColumns.MIME_TYPE, recorder.getMimeContentType());

/* Create entry in the content database */

ContentResolver contentResolver = new ContentResolver();

Uri base = MediaStore.Audio.INTERNAL_CONTENT_URI;

Uri newUri = contentResolver.insert(base, values);

if (newUri == null) {

    /* Handle exception here - not able to create a new content entry */

}

/* Receive the real path as String */

String path = contentResolver.getDataFilePath(newUri);

/* Set Audio Source, Format, Encode and File */

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);

recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);

recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

recorder.setOutputFile(path);

/* Prepare the Recorder */

recorder.prepare();

/* Start Recording */

recorder.start();

/* ... */

/* Stop Recording Again */

recorder.stop();

recorder.release();
