**Android TextureView & MediaPlayer implements video media player**

code:

import android.graphics.SurfaceTexture;
    import android.media.AudioManager;
    import android.media.MediaPlayer;
    import android.os.Environment;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.Surface;
    import android.view.TextureView;
    
    import java.io.File;
    
    public class MainActivity extends AppCompatActivity {
    
        private MediaPlayer mMediaPlayer;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
    
            TextureView textureView = new TextureView(this);
            setContentView(textureView);
    
            textureView.setSurfaceTextureListener(new TextureView.SurfaceTextureListener() {
                @Override
                public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
                    Surface mSurface = new Surface(surface);
                    player(mSurface);
                }
    
                @Override
                public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {
    
                }
    
                @Override
                public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
                    mMediaPlayer.stop();
                    mMediaPlayer.release();
    
                    return false;
                }
    
                @Override
                public void onSurfaceTextureUpdated(SurfaceTexture surface) {
    
                }
            });
        }
    
        private void player(Surface surface) {
            try {
                File file = new File(Environment.getExternalStorageDirectory() + "/video.mp4");
    
                mMediaPlayer = new MediaPlayer();
                mMediaPlayer.setDataSource(file.getAbsolutePath());
                mMediaPlayer.setSurface(surface);
                mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mMediaPlayer.start();
                    }
                });
                mMediaPlayer.prepare();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
