How to Retrieve an Uploaded File from Firebase Storage: A Guide for Beginners

If you're developing an Android application and have recently begun working with Firebase, you might be wondering: How do I retrieve images or files that I have uploaded to Firebase Storage? This is a common question among new developers, and understanding the process is crucial for displaying content in your app effectively. In this guide, we will guide you through the steps to retrieve a file from Firebase Storage after uploading it.

You can see that after uploading the image, Firebase successfully handles the process and informs you of the upload’s completion. However, to be able to utilize that uploaded image later, you need to retrieve its location (or URL) in your database.

Steps to Retrieve the Download URL

1. Get the Download URL After Upload

Once your upload is successful, it’s important to obtain the download URL for your uploaded image. Instead of using Uri downloadURL = tasksnapshot.getDownloadURL, you can retrieve the download URL using the following code:

2. Storing the Download URL

After obtaining the download URL, it's a good practice to store it in your database. Whether you are using Firestore, Firebase Realtime Database, or any other database solution provided by Firebase, storing the download URL allows you to easily retrieve the image whenever needed.

3. Reading the Download URL from the Database

To display the image in your app, you need to query your database to get the stored download URL. Here’s a simple outline of what you need to do:

Query your Firebase database for the stored download URL.

Once you have the URL, you can use it within your application’s image views.
