                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();

    private void stopRecording() {

        System.out.println("Stop Recording");

        try {
            if (null != recorder) {
                recorder.stop();
                recorder.reset();
                recorder.release();
                recorder = null;
            }

        } catch (IllegalStateException e) {
            e.printStackTrace();
        }

    }

    private String getFilePath() {
        File rsd = Environment
                .getExternalStoragePublicDirectory(Environment.DIRECTORY_MUSIC);
        if (!rsd.isDirectory()) {
            rsd.mkdir();
        }
        File dcim = new File(rsd + "/hello.mp3");

        return dcim.getAbsolutePath();
    }

The file you want to listen is mp3 the format that you have in recorder is MediaRecorder.OutputFormat.THREE_GPP, maybe that's the reason... — Rafael Barradas, Jul 31 '13 at 22:12
I think you need to add a library... Maybe this help you: http://stackoverflow.com/questions/3641920/how-to-encode-a-wav-to-a-mp3-on-a-android-device/ — Rafael Barradas, Jul 31 '13 at 22:18

Yup like Ralph House said in comment, you should save your file with .3gp extention. Change

File dcim = new File(rsd + "/hello.mp3");

To:

File dcim = new File(rsd + "/hello.3gp");
