Copy the video into your project's res/raw folder. Create raw folder under res folder. It must be in a supported format (3gp, wmv, mp4 ) and named with lower case, numerics, underscores and dots in its filename likewise:video_file.mp4.

VideoView view = (VideoView)findViewById(R.id.videoView);
String path = "android.resource://" + getPackageName() + "/" + R.raw.video_file;
view.setVideoURI(Uri.parse(path));
view.start();

Create videoView in your xml file.

// To get files from any resource folder (eg: raw, drawable, etc.)
// Use the resource id
int rawId = getResources().getIdentifier(file_name_without_extension,  "raw", getPackageName());

// URI formation
String path = "android.resource://" + getPackageName() + "/" + rawId;

// Set the URI to play video file
videoView.setVideoURI(Uri.parse(path));

i think , everyone gave an answer, but doesn't explain the scenario. The main problem here is, If im not mistaken , Android assume that the video coming from your SD Card is dynamic, where in it could be possible , that the format is not supported or supported, thus it enables / ask you to select or open for other third party media software.

While anything you play UNDER RAW folder, requires a handler such as videoview or built in media player which leads to conclusion that anything you put in your RAW folder should be supported / readable by the Android OS.

However , the thread starter here wants that his RAW files , to be played using a third party media player.

I struggled with this for dynamic video names. The solution that worked for me was:

//Somewhere set the video name variable
String video+name="myvideo";
//setup up and play video

VideoView videoView=(VideoView)findViewById(R.id.video);
videoView.setVisibility(View.VISIBLE);
String uriPath = "android.resource://"+getPackageName()+"/raw/"+ video_name;
Uri UrlPath=Uri.parse(uriPath);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(videoView);
videoView.setMediaController(mediaController);
videoView.setVideoURI(UrlPath);

videoView.setOnPreparedListener(new OnPreparedListener() {
        public void onPrepared(MediaPlayer mediaPlayer) {
            if (position == 0) {
                try{
                    videoView.requestFocus(); 
                    videoView.start();
                }catch (Exception e){
                    System.out.printf("Error playing video %s\n", e);
                }
            }else{
                videoView.pause();
            }

        }
});

And in XML

<VideoView android:layout_width="300dp"
    android:id="@+id/video"
    android:layout_height="300dp"
    android:orientation="horizontal"
    android:layout_gravity="center" 
    android:keepScreenOn="true"
    />
