How does one use Glide to download an image into a bitmap

This example demonstrates how do I does one Glide to download an image into a bitmap.

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

Add the following dependency in build.gradle: Module: app

implementation 'com.github.bumptech.glide:glide:4.9.0'

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

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout 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"

   tools:context=".MainActivity">

   <ImageView

      android:id="@+id/imageView"

      android:layout_width="match_parent"

      android:layout_height="match_parent" />

</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

public class MainActivity extends AppCompatActivity {

   ImageView imageView;

   @Override

   protected void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      setContentView(R.layout.activity_main);

      imageView = findViewById(R.id.imageView);

      Glide.with(this).asBitmap().load("https://www.google.es/images/srpr/logo11w.png").into(new CustomTarget<Bitmap>() {

         @Override

         public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {

            imageView.setImageBitmap(resource);

         }

         @Override

         public void onLoadCleared(@Nullable Drawable placeholder) {

         }

      });

   }

}

Step 4 − 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">

   <uses-permission android:name="android.permission.INTERNET"/>

   <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 Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen
