How to play videos in Android TextureView?

This example demonstrates how do I play videos in Android TextureView.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical"
   android:padding="8dp"
   tools:context=".MainActivity">
<TextureView
   android:id="@+id/textureView"
   android:layout_width="match_parent"
   android:layout_height="match_parent"/>
</LinearLayout>

Step 3 − Create an asset folder and copy-paste the video into the asset folder.

Step 4 − Add the following code to src/MainActivity.java

import androidx.appcompat.app.AppCompatActivity;
import android.content.res.AssetFileDescriptor;
import android.graphics.SurfaceTexture;
import android.media.MediaPlayer;
import android.os.Build;
import android.os.Bundle;
import android.view.Surface;
import android.view.TextureView;
import java.io.IOException;
public class MainActivity extends AppCompatActivity implements TextureView.SurfaceTextureListener, MediaPlayer.OnVideoSizeChangedListener {
   TextureView textureView;
   private MediaPlayer mediaPlayer;
   AssetFileDescriptor fileDescriptor;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textureView = findViewById(R.id.textureView);
      textureView.setSurfaceTextureListener(this);
      mediaPlayer = new MediaPlayer();
      try {
         fileDescriptor = getAssets().openFd("videoplayback.mp4");
      }
       catch (IOException e) {
         e.printStackTrace();
      }
   }
   @Override
   public void onSurfaceTextureAvailable(SurfaceTexture surfaceTexture, int width, int height) {
      Surface surface = new Surface(surfaceTexture);
      try {
         mediaPlayer.setSurface(surface);
         if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            mediaPlayer.setDataSource(fileDescriptor);
            mediaPlayer.prepareAsync();
            mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
               @Override
               public void onPrepared(MediaPlayer mp) {
                  mediaPlayer.start();
               }
            });
         }
      }
      catch (IOException e) {
         e.printStackTrace();
      }
   }
   @Override
   public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {
   }
   @Override
   public boolean onSurfaceTextureDestroyed(SurfaceTexture surface) {
      return false;
   }
   @Override
   public void onSurfaceTextureUpdated(SurfaceTexture surface) {
   }
   @Override
   public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
   }
}

Step 5 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from the android studio, open one of your project's activity files and click the Run   icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
