Video
By the help of MediaController and VideoView classes, we can play the video files in android.
- Dsiplaying loacal videos
- Create an application that displays a video clip, which is stored locally
in our applications “res” directory
- Create a row directory
Paste video file to raw directory
- Add VideoView to your UI
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

MainActivity.java
package com.lb.videoplay;
import androidx.appcompat.app.AppCompatActivity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoView videoView = (VideoView) findViewById(R.id.videoView);
//Attach a media controller to video view
MediaController mediaController = new MediaController(this);
videoView.setMediaController(mediaController);
mediaController.setAnchorView(videoView);
//Specify the location of media file
Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.favicon);
videoView.setVideoURI(uri);
videoView.requestFocus();
videoView.start();
}
}
previous tutorial we are discuss about
how to play video on videoview from local file
First set to internet permission
your manifest must include the permissions:
<uses-permission android:name="android.permission.INTERNET" />
Then and to video url
Check this code
package com.lb.videoplay;
import androidx.appcompat.app.AppCompatActivity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
VideoView videoView = (VideoView) findViewById(R.id.videoView);
//Attach a media controller to video view
MediaController mediaController = new MediaController(this);
videoView.setMediaController(mediaController);
mediaController.setAnchorView(videoView);
//add your video URL
Uri uri = Uri.parse("Add URL here..");
videoView.setVideoURI(uri);
videoView.requestFocus();
videoView.start();
}
}
Create file res/xml/network_security_config.xml
<?xml version="1.0" encoding="utf-8"?> <network-security-config> <base-config cleartextTrafficPermitted="true"> <trust-anchors> <certificates src="system" /> </trust-anchors> </base-config> </network-security-config>
New in the AndroidManifest.xml file under application:
android:networkSecurityConfig="@xml/network_security_config"
sudo apt update && upgrade
sudo apt-get install php
Install MySql and phpMyAdmin
sudo apt-get install mysql-server
mysql-client
Then install phpmyadmin
sudo apt-get install phpmyadmin -y
Then check phpmyadmin
The requested URL /phpmyadmin was not found on this server
sudo -H gedit /etc/apache2/apache2.conf
add following line to end of apache config file
Include /etc/phpmyadmin/apache.conf
Then restart apache:
/etc/init.d/apache2 restart

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnPlay = (Button) findViewById(R.id.btnPlay);
aYouTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtubeplay);
mOnInitializedListener = new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
//Load video list
/* List<String> videoList = new ArrayList<>();
videoList.add("saIqHKolTHc");
videoList.add("ov8YX9tNyio");
youTubePlayer.loadVideos(videoList); */
//play list
//youTubePlayer.loadPlaylist("PLIFW--Hzc0hbgKs_ZIzMWnElNkHkpsmGP");
//play video
youTubePlayer.loadVideo("saIqHKolTHc");
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
}
};
btnPlay.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
aYouTubePlayerView.initialize(Config.getYoutubeApiKey(),mOnInitializedListener);
}
});
}
}
Thanks You
