this is my code:

protected void prepareVideoView(File video, String clipId) {

    // final Activity currentView = this;
    final VideoView vv = (VideoView) findViewById(R.id.video);

    vv.setOnErrorListener(Library_callHandler.getErrorHandler(video));
    vv.setVideoPath(video.getAbsolutePath());
    vv.setVisibility(View.VISIBLE);
    vv.setVerticalScrollBarEnabled(false);
    vv.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mp) {
            try {
                int counter = 0;
                while (vv.isPlaying() && counter++ < 3) {
                    try {
                        Thread.currentThread();
                        Thread.sleep(100);
                    } catch (InterruptedException ignore) {
                    }
                }
                if (vv.isPlaying()) {

                    com.vringo.shared.Log
                            .log(com.vringo.shared.Log.LEVEL_INFO,
                                    "VmcRingerActivity onCompletion vv.isPlaying()--> finish()");
                    finishInstance();
                    return;
                }
                vv.start();
            } catch (IllegalStateException e) {
                // ResidentService.restoreRinger(currentView);
            }
        }
    });
    vv.start();

    Library_callHandler.track_info("CLIP_RINGTONE", clipId);
    // - tracker.trackEvent(VringoConstants.CAT_CLIPS,
    // VringoConstants.ACT_PLAY_RINGER,
    // String.valueOf(videoClip.getClipId()), 0);
    // - tracker.dispatch();

    // Library_callHandler.info("Ringer video playback started.");
