How does one use glide to download an image into a bitmap?

Question

Downloading a URL into an ImageView is very easy using Glide:

Glide
   .with(context)
   .load(getIntent().getData())
   .placeholder(R.drawable.ic_loading)
   .centerCrop()
   .into(imageView);

I'm wondering if I can download into a Bitmap as well? I'd like to download into a raw bitmap that I can then manipulate using other tools. I've been through the code and don't see how to do it.

Make sure you are on the Lastest version

implementation 'com.github.bumptech.glide:glide:4.10.0'

Kotlin:

Glide.with(this)
        .asBitmap()
        .load(imagePath)
        .into(object : CustomTarget<Bitmap>(){
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                imageView.setImageBitmap(resource)
            }
            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })

Bitmap Size:

if you want to use the original size of the image use the default constructor as above, else You can pass your desired size for bitmap

into(object : CustomTarget<Bitmap>(1980, 1080)

Java:

Glide.with(this)
        .asBitmap()
        .load(path)
        .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) {
            }
        });

Old Answer:

With compile 'com.github.bumptech.glide:glide:4.8.0' and below

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }
        });

For compile 'com.github.bumptech.glide:glide:3.7.0' and below

Glide.with(this)
        .load(path)
        .asBitmap()
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                imageView.setImageBitmap(resource);
            }
        });

Now you might see a warning SimpleTarget is deprecated

Reason:

The main point of deprecating SimpleTarget is to warn you about the ways in which it tempts you to break Glide's API contract. Specifically, it doesn't do anything to force you to stop using any resource you've loaded once the SimpleTarget is cleared, which can lead to crashes and graphical corruption.

The SimpleTarget still can be used as long you make sure you are not using the bitmap once the imageView is cleared.
