System.out.println("audio_file_path : = " + path);
recorder.setOutputFile(path);
recorder.prepare();

recorder.start();  // Recording is now started

If you just need the file to show art in the Android Media player, consider adding album art using the Google Content Provider. After creating your 3GP file, scan it using the MediaScannerConnection API. After it's been added to the database, you can access it using a ContentResolver in your activity or service. The MediaScannerConnection will give you a URI for your newly created file. You can try placing the new art you'd like in a location on the sdcard. Then, call: getContentResolver().udpate(uri, newArtContentValue, null, null). The newArtContentValue is an instance of a ContentValue object, with a key of MediaStore.Audio.AudioColumns.ALBUM_ART and a value of file:///sdcard/yourartfile.png.

Caveat: I haven't actually tried this, so it may need small tweaks. You may need to change the extension of your file so that Google treats it as an audio file rather than a video file, so that the ALBUM_ART field exists. There may be other cases I haven't considered, as well.

If you absolutely must embed the art in the file itself:

3gp files do not (to my knowledge) support covert art metadata embedded in the file. So, you'l have to record to another container format that does. Even then, I think the only available OutputFormat that supports covert art metadata is MP4, and I'm not aware of any Android functionality that allows you to modify media files directly to add such tags.
