package com.example.lssonline;

import android.app.Activity;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;
import android.widget.VideoView;

public class VideoActivity extends Activity {
	VideoView vv;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_video);
		vv = (VideoView)findViewById(R.id.videoView1);
		
		vv.setVideoURI(Uri.parse("https://khoapham.vn/download/vuoncaovietnam.mp4"));
		vv.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
			
			@Override
			public void onPrepared(MediaPlayer arg0) {
				// TODO Auto-generated method stub
				arg0.start();
			}
		});
		
	}
}
