Building a Simple Video Player

In this exercise,

1. A small VideoView without media controller will auto play video at the beginning of launching app;
   
2. If we single touch the VideoView, it will activate full screen mode and resume it at the stopped position in small VideoView;
   
3. If we touch the back button in full screen mode, it will return to the small VideoView and and resume it at the stopped position in full screen mode.

Basic VideoView

1. Create an empty project
   
2. Create a folder named raw in res
   
3. Add a local video in MP4 format in raw folder
   
   
   
4. Create a MainActivity with layout(activity_main.xml)
   activity_main.xml
   
   MainActivity.java
   

   public class MainActivity extends AppCompatActivity {
       private String TAG = "MainActivity";
       private VideoView videoView;
       private String videoPath;
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
           setContentView(R.layout.activity_main);
           videoView = (VideoView) this.findViewById(R.id.video_view);
           videoPath = "android.resource://" + getPackageName() + "/" + R.raw
                   .google_arts_and_culture;
           videoView.setVideoURI(Uri.parse(videoPath));
           videoView.start();       
       }
   }
   

Full Screen VideoView with MediaController

Create a FullscreenVideoActivity with layout(activity_fullscreen_video.xml)
activity_fullscreen_video.xml

FullscreenVideoActivity.java

public class FullscreenVideoActivity extends Activity {
    private String TAG = "FullscreenVideoActivity";
    private VideoView videoView;
    private MediaController mc;
    private String videoPath;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fullscreen_video);
        mc = new MediaController(this);
        videoView = (VideoView) this.findViewById(R.id.fullscreen_video_view);
        videoView.setMediaController(mc);
        videoPath = "android.resource://" + getPackageName() + "/" + R.raw
                .google_arts_and_culture;
        videoView.setVideoURI(Uri.parse(videoPath));
        videoView.start();
    }
}

From Basic VideoView into Full Screen Mode

Attaching a SimpleOnGestureListener to basic the VideoView for triggering full screen.
MainActivity.java

public class MainActivity extends AppCompatActivity {
    private String TAG = "MainActivity";
    private int stopPosition;
    private VideoView videoView;
    private String videoPath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        setContentView(R.layout.activity_main);
        videoView = (VideoView) this.findViewById(R.id.video_view);
        videoPath = "android.resource://" + getPackageName() + "/" + R.raw
                .google_arts_and_culture;
        videoView.setVideoURI(Uri.parse(videoPath));
        videoView.start();
        final GestureDetector gestureDetector = new GestureDetector(this, gestureListener);
        videoView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return gestureDetector.onTouchEvent(event);
            }
        });
    }

    final GestureDetector.SimpleOnGestureListener gestureListener =
            new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onDown(MotionEvent event) {
            return true;
        }

        @Override
        public boolean onSingleTapUp(MotionEvent event) {
            Log.e(TAG, "onSingleTapUp");
            return true;
        }
        @Override
        public boolean onSingleTapConfirmed(MotionEvent e) {
            Log.e(TAG, "onSingleTapConfirmed");
            videoView.pause();
            stopPosition = videoView.getCurrentPosition();
            Intent intent = new Intent(MainActivity.this, FullscreenVideoActivity.class);
            intent.putExtra("videoPath", videoPath);
            intent.putExtra("stopPosition", stopPosition);
            startActivity(intent);
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            super.onLongPress(e);
            Log.e(TAG, "onLongPress");
        }

        @Override
        public boolean onDoubleTap(MotionEvent e) {
            Log.e(TAG, "onDoubleTap");
            return super.onDoubleTap(e);
        }
    };
}

FullscreenVideoActivity.java

public class FullscreenVideoActivity extends Activity {
    private String TAG = "FullscreenVideoActivity";
    private VideoView videoView;
    private MediaController mc;
    private String videoPath;
    private int stopPosition;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fullscreen_video);
        Bundle params = getIntent().getExtras();
        videoPath = params.getString("videoPath");
        stopPosition = params.getInt("stopPosition");
        mc = new MediaController(this);
        videoView = (VideoView) this.findViewById(R.id.fullscreen_video_view);
        videoView.setMediaController(mc);
        videoView.setVideoURI(Uri.parse(videoPath));
        Log.e(TAG, "FullscreenVideoView intent stop position: " + stopPosition);
        videoView.seekTo(stopPosition);
        videoView.start();
    }
}

Back to Basic VideoView from Full Screen Mode

Overriding onResume() method of MainActivity for getting bundle with video stop position and file path from FullscreenVideoActivity.
MainActivity.java

@Override
protected void onResume() {
    super.onResume();
    Bundle params = getIntent().getExtras();
    if(null != params){
        Log.e(TAG, "VideoView intent stop position: " + stopPosition);
        videoPath = params.getString("videoPath");
        stopPosition = params.getInt("stopPosition");
        videoView.seekTo(stopPosition);
        videoView.start();
    }
}

FullscreenVideoActivity.java
Overriding onBackPressed() method of FullscreenVideoActivity for going back to MainActivity with video stop position and file path.

@Override
public void onBackPressed() {
    super.onBackPressed();
    videoView.pause();
    stopPosition = videoView.getCurrentPosition();
    Intent intent = new Intent(FullscreenVideoActivity.this, MainActivity.class);
    intent.putExtra("videoPath", videoPath);
    intent.putExtra("stopPosition", stopPosition);
    startActivity(intent);
}
