Do something on placeholder applied to Glide?

Can I know if there is any method that I can use to do something when loading placeholder to the Glide. Here I have set a firebase image url to setBitmap method using Glide. if resource available setBitmap method will run. If it is not available I want to run a another method. Is there a method something like onLoadingPlaceholder()?

 Glide.with(getApplicationContext()).asBitmap()
                            .load(dataSnapshot.child("imageUrl").getValue(String.class))
                            .apply(new RequestOptions()
                                    .diskCacheStrategy(DiskCacheStrategy.ALL)
                                    .placeholder(R.drawable.image)
                                    .error(R.drawable.image))
                            .into(new CustomTarget<Bitmap>() {
                                @Override
                                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                                    Log.d(TAG, "onResourceReady: ");
                                    setBitmap(resource);
                                }

                                @Override
                                public void onLoadCleared(@Nullable Drawable placeholder) {}
                            });

Simply What I need to do is that, set a bitmap when placeholder load. So I need to set a default image when firebase image is not available.

Answer

Finally, I found the answer. But it is not something like onLoadPlaceholder(), This works for me!

String imageUrl = dataSnapshot.child("imageUrl").getValue(String.class);
if(imageUrl==null){
    setBitmap(resource);
}

Glide.with(getApplicationContext()).asBitmap()
        .load(imageUrl)
        .apply(new RequestOptions()
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .placeholder(R.drawable.contatctmani)
                .error(R.drawable.contatctmani))
        .into(new CustomTarget<Bitmap>() {
            @Override
            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                setBitmap(resource);
            }

            @Override
            public void onLoadCleared(@Nullable Drawable placeholder) {}
        });
