With RequestBuilder you can configure the request for thumbnail with a multiplier. below is an example

Currently, I don't have many images to access from the Firebase but suppose the number turns to something like 500, will this part of the code do any harm in the long run?

It's not about a particular part of your code as it's about the amount of data you download. It's not a recommended approach to request all those 500 images at once. Besides that, I don't think that somebody will be interested in seeing all those images. Not to mention that will take a large amount of time. So the best option that you have is to limit the number of images you read.

How can you achieve that? Simply by storing the URL of each image, either in Cloud Firestore or in the Realtime Database, and read them in smaller chunks. A common approach would be to always display the exact number of images that you are able to display on the screen. That being said, you should consider getting data progressively. You can also consider implementing pagination if your app's use case requires it.

I also got to know about something called "DiffUtil" but don't want to experiment on something new right now.

According to the docs:

DiffUtil is a utility class that calculates the difference between two lists and outputs a list of update operations that converts the first list into the second one.

So if you still consider downloading all those 500 images in one go, DiffUtil won't save bandwidth for you.

I believe your goal is as follows.

• You want to search the file of filename subject retrieved from the cell "B3" of "Source Email-Boom" sheet from your Google Drive, and when the value of subject is found from the column "AI" of "BL-Inspection Report" sheet, you want to put the URL of the file to the column "AJ".
• For my question of For example, you want to put the URL of the just created file?, from Yes of your replying, I understood that you wanted to put the URL of the just created file in this script.

In this case, how about the following modification? I thought that in this case, the file URL of the just created file can be directly retrieved from DriveApp.getFolderById(folderID).createFile(response).setName(nameFile). So, how about the following modification?

As Cooper pointed out, try Utilities.sleep()

The parameter is stated in milliseconds, so for a 3-second delay, you can add this to your script where the pause is desired:

ListAdapter doesn’t work with mutable lists. This is because if you modify the contents of the List, when it tries to compare the contents of the old list and new list, it’s comparing the same list to itself. There is no old list instance that still holds the old contents, so it cannot detect any differences.

Instead of mutating the original list, you should create a new one, for example

the error was the *10 inside function draw()

it says in Glide documentation about permissions

To load images from local folders like DCIM or Pictures, you’ll need to add the READ_EXTERNAL_STORAGE permission

so could it be the case that you didn't declare this permission in your android Manifest ?

if all you want is to load an image using Glide into an ImageView, then you don't need to extend any class inorder to use Glide.

you can just load the the image using its Uri with this line of code :

It turned out to be a dumb error. My projection was still using most of the fields from the Image projection:
