How to access in android the users registered in Firebase Authentication

Question

I am creating an android app integrated with Firebase as the backend. I used Firebase Authentication for the authentication and management of users. I also used Firestore for the database. In my app, there will be a data(collection) named LoanRecord with the fields of lender and borrower. These 2 fields will contain user data (like foreign key in SQL database). Every time a user will create a LoanRecord data, the app will need to fetch the available users, so that the user can select and set it to the lender and borrower fields.

Now how can I fetch all the users to my android app? I do not have my own backend, so I cannot use the Firebase Admin SDK. I also don't want to use the cloud functions because apparently it's not free (this app is only for my personal use so I don't want to spend money for it).

For sure there is. Please edit your question and add your database structure as a screenshot. Are you using Java or Kotlin? — Alex Mamo, Sep 11 '21 at 08:15
Please edit your question and add your real database structure as a screenshot and indicate the exact data you want to get. — Alex Mamo, Sep 11 '21 at 09:51

Since you indicate not wanting to use Cloud Functions, the solution would be to have each user write their own user data to the database when they register/sign-in.

You can then refer to that information in the database when you need it.

This has been covered quite a few times before already, so I recommend checking out:
