            int pos=msg.what;
            if (pos == 1){

                video_view.setVideoPath(Environment.getExternalStorageDirectory()+"/"+ex_name+".mp4");
                video_view.requestFocus();
                video_view.start();

                Log.d("Before Video Finish", "i m in before video finish");
                video_view.setOnCompletionListener(new OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mp) {
                        finish();

Create an activity and call it when you need to play the video. You can bundle the video path (whether url or sdcard or a resource) in the Intent. Then in your activity which should only contain a FrameLayout with a VideoView do something like:

    Intent intent = getIntent();
    Bundle extras = intent.getExtras();
    if (extras != null) {
        mVideoPath = extras.getString(INTENT_EXTRA_URI);
        int resId = getResId(mVideoPath, R.raw.class);
                    String uriPath = null;
        if (mVideoPath.startsWith("http://") || mVideoPath.startsWith("https://")) {
            uriPath = mVideoPath;
        } else if (mVideoPatah.startsWith("/mnt/sdcard/")) {
            uriPath = mVideoPath;
        } else {
            int resId = getResId(mVideoPath, R.raw.class);
            uriPath = "android.resource://" + getResources().getResourcePackageName(resId) + "/" + resId;
        }
        mVideoView.setVideoURI(Uri.parse(uriPath));
        MediaController mediaController = new MediaController(this);
        mVideoView.setMediaController(mediaController);
        mVideoView.requestFocus();
        mVideoView.start();         
    }
