Glide is a popular image-loading and caching library for Android apps. It simplifies the process of fetching, resizing, and displaying images efficiently. With Glide, you can load images from various sources such as URLs, local files, or even resources, and apply transformations to them.
To use the Glide image loading library in your Android app, follow these steps:

Step 1: Add Glide to your project
Add the Glide dependency to your app-level build.gradle file:

implementation 'com.github.bumptech.glide:glide:4.12.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.12.0'

Step 2: Add permissions (if necessary)
If you want to load images from the internet, make sure you have the necessary permissions in your AndroidManifest.xml file.
Add the following line inside the tag:

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

Step 3: Load an image
Now you can use Glide to load images in your app.
Here's an example of loading an image into an ImageView:

import com.bumptech.glide.Glide;
import com.bumptech.glide.request.RequestOptions;

// ...

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide
Glide.with(this)
    .load(imageUrl)
    .apply(new RequestOptions()
        .placeholder(R.drawable.placeholder) // Placeholder image while loading
        .error(R.drawable.error)) // Error image if loading fails
    .into(imageView);

In the above example, replace R.drawable.placeholder with the resource ID of your placeholder image and R.drawable.error with the resource ID of your error image.

Step 4: Additional configuration (optional)
You can configure additional options for image loading, such as resizing, caching, transformations, etc. Glide provides a wide range of customization options.
Here's an example of resizing the loaded image:

Glide.with(this)
    .load(imageUrl)
    .apply(new RequestOptions()
        .override(500, 500)) // Resize the image to 500x500 pixels
    .into(imageView);

This resizes the loaded image to a maximum width and height of 500 pixels while preserving the aspect ratio.
To perform a circle crop on an image using Glide, you can use the .circleCrop() method.
Here's an example:

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide and apply circle crop transformation
Glide.with(this)
    .load(imageUrl)
    .circleCrop()
    .into(imageView);

Another Written Description

In the above code, the circleCrop() method is chained to the Glide builder to apply the circle crop transformation to the loaded image. This will crop the image into a circular shape and display it in the imageView.
To apply multiple transformations to an image using Glide, you can chain multiple transformation methods together.
Here's an example:

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide and apply multiple transformations
Glide.with(this)
    .load(imageUrl)
    .apply(RequestOptions.circleCropTransform()) // Apply circle crop transformation
    .apply(RequestOptions.bitmapTransform(new RoundedCorners(10))) // Apply rounded corners transformation
    .into(imageView);

In the above code, two transformation methods are applied to the loaded image:
.apply(RequestOptions.circleCropTransform()): This applies the circle crop transformation to the image, making it appear in a circular shape.
.apply(RequestOptions.bitmapTransform(new RoundedCorners(10))): This applies the rounded corners transformation to the image, rounding the corners with a radius of 10 pixels.
To apply a blur effect to an image using Glide, you can use the BlurTransformation class.
Here's an example:

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide and apply blur transformation
Glide.with(this)
    .load(imageUrl)
    .apply(RequestOptions.bitmapTransform(new BlurTransformation(25, 3))) // Apply blur transformation
    .into(imageView);

In the above code, the BlurTransformation is applied to the loaded image using the .apply() method. The BlurTransformation constructor takes two parameters: radius and sampling.
radius determines the extent of blurring, where a higher value produces a more pronounced blur effect.
sampling controls the number of times the image is downsampled, affecting the performance and quality of the blur effect. A higher value improves quality but reduces performance.
When using Glide in Android, you can handle errors that may occur during image loading by setting up an error listener or specifying an error placeholder. Here's how you can handle errors in Glide:
Error Placeholder:
You can set an error placeholder image to be displayed when an error occurs during image loading. This placeholder will be shown instead of the intended image.
Here's an example:

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide and set an error placeholder
Glide.with(this)
    .load(imageUrl)
    .error(R.drawable.error_placeholder) // Error placeholder image
    .into(imageView);

In the above code, R.drawable.error_placeholder refers to the resource ID of the error placeholder image. Replace it with the resource ID of your own error placeholder image.
Error Listener:
Glide allows you to set an error listener to handle specific actions when an error occurs during image loading. For example, you can log an error message, display a toast, or perform any other desired action.
Here's an example of setting an error listener:

ImageView imageView = findViewById(R.id.imageView);

String imageUrl = "https://example.com/image.jpg";

// Load the image with Glide and set an error listener
Glide.with(this)
    .load(imageUrl)
    .error(R.drawable.placeholder) // Placeholder image
    .listener(new RequestListener<Drawable>() {
        @Override
        public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
            // Handle the error here (e.g., show a toast or log an error message)
            Log.e("Glide", "Image loading failed: " + e.getMessage());
            return false; // Return false to allow Glide to handle the error and show the error placeholder image
        }

        @Override
        public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
            // Image loaded successfully
            return false; // Return false to allow Glide to handle the resource and display it in the ImageView
        }
    })
    .into(imageView);

In the above code, the listener() method is used to set an error listener by implementing the RequestListener interface. Inside the onLoadFailed() method, you can handle the error as per your requirements, such as displaying a toast message or logging an error. Returning false allows Glide to handle the error and show the error placeholder image.
By following these steps and utilizing the various configuration options, you can effectively integrate and utilize the Glide image-loading library in your Android app.
