Does loading Firebase Storage image with Glide generate billing expenses? - firebase

Question

I would like to know if this action that I am doing in my application generates expenses for Firebase Storage. That is,
if regardless of the times I do the following action it will generate some expense in Firebase billing.
I have images stored in storage, and I upload these images to an ImageView using the Glide library, like this:
Uri url = Uri.parse(pictureUser);
Glide.with(MainActivity.this).load(url).into(imageView);
I have a chat application, and in each message on the adapter I want to upload the user's photo this way, using Glide, so, as there are many uploads, I wanted to know if every time I run this code snippet, it generates some billing expenses of the firebase.

As you are using this in chat activity this means that same image may probably load many of times.
To decrease the number of images that download I suggest you to use instead of:
Glide.with(MainActivity.this).load(url).into(imageView);
replace it by :
Glide.with(MainActivity.this)
.load(url).diskCacheStrategy(DiskCacheStrategy.DATA)
.into(imageView);
by this way, you are activating the cache mode. this means the Glide will search in the cache if it exists then will upload it from the internet.
I advise you to use Picasso instead of Glide. it works better in mode offline than Glide:
Picasso.with(MainActivity.this)
.load(url)
.networkPolicy(NetworkPolicy.OFFLINE)
.into(imageView, new Callback() {
#Override
public void onSuccess() {
}
#Override
public void onError() {
// Try again online if cache failed
Picasso.with(MainActivity.this)
.load(url)
.error(R.drawable.user_placeholder_error)
.into(imageView);
}
});

Any time your code download a file, it will be billed as egress from Cloud Storage.
With Glide, it as a disk cache enabled by default, so it should only download a URL once and reuse it from cache (as long as it remains in cache). That would not be billed, since it's not downloading anything from the cloud.
