How can i retrieve 1 image at a time using Picasso to display as a Profile Picture of currently logged-in user??
I saw many other solutions on stackoverflow but all of them were related to Recycler View for displaying all images in list format.
In short how can I make a reference to Firebase Storage to fetch image?
Thanks in advance.
In short, how can I make a reference to Firebase Storage to fetch the image?
In order to be able to get an image from Firebase Storage, you need to know its path. If you need to get that path directly from the Firebase Console, you should click on an image, and on the right-hand side will see a section named File location. Inside this section, under the Access token, you'll see the actual access token of the image. Simply clicking on the token, will copy the entire download URL in the clipboard. Paste it in your project and that's it.
If you need it programmatically, please check my answer from the following post:

I want to retrieve the image of the connected user like on play stores app in drawer menu but not a success and I don't know how to proceed. I have succeeded to show the user's name and email but not the image.
Imagining you have url of the images stored in firebase server you can use GLIDE library (library link) to download and display the images from any server not only firebase
If you don't have the image stored in database then you should first store it and then retrieve it from url. you can learn how to do it from here
I'm trying to make my Flutter app work offline with Firebase. I store a reference to my images on Firestore and the image files on Storage. I got the Firestore part working, and I'm using a CachedNetworkImageProvider to display my images, which caches for offline use. But when I'm offline, even though the image is cached, I can't get the URL for the image, so I can't pass it to CachedNetworkImageProvider, which uses the URL as the key.
So while offline I know the image path, and I have the file stored on device, I just need a way to get the URL.
Do I need to manually store the download URLs from Storage on the device so that I can use them offline? Or is there a better way?
Code to get the URL:
// this doesn't work offline
category.url = await storage
.ref()
.child("category_images/drawable-${DeviceInfo.dpiString}")
.child(document.data["media"]["src"])
.getDownloadURL();
Code to display the image:
image: new CachedNetworkImageProvider(_category.url),
You need to save the URL too. A good place could be in that image reference you have in firestore.
The other option is to use the local file since you say you know the path, though I think referring through the URL is cleaner.
Hi guys I am making a wallpaper android app.I have stored all my images in firebase storage. Now I have a recyclerview and want to retrieve each of the images into that recyclerView by getting list url of the folders.Is there any way to do that without using the database.I have pasted the json file into my app.
In order to download a image/images from Firebase Storage, you first need to have the corresponding url/urls. To download an image, it requires four steps:
Upload the image to Firebase Storage.
Save the corresponding URL to Cloud Firestore/Firebase Database database while uploading.
Attach a listener on the folder you have saved the image.
Display the image.
So there is no way in which you can download an image without knowing the URL. You cannot get the image list URL directly from Firebase Storage.
First at all you need to have corresponding URLs of your image data stored in Firebase, as mention Alex Mamo. You can build list of this urls during upload or copy them from Firebase Console. Storage API doesn't provide any way how to retreive list of stored files.
Also, you can find Download URL in Image detail/properties. Then you can insert urls into JSON file (or another file, service, firebase storage, whatever) and load them in app.
But be careful, this is not a good idea because Firebase Storage (especially spark plan has limits) allow you download 1GB/day and only 50k/day (download/upload) operations. That will be wasted pretty soon if you don't optimise your data and number of reading operations.
Tip: When you select pay as you go most expensive is GB Downloaded, so you absolutely should store at least 1 thumbnail which will be shown in your recycler view.
I am creating an Android App where Firebase is the backed. In my app, I have some selected images that I have stored inside my Firebase storage by direct uploading (Without coding).
Now I have to view that images in my app through a recycle view. For that purpose, I have to get the download URL of all the images and put them into my Firebase real-time database programmatically so that I can access the URL to my app. Is there any methods available for that?
I have tried to iterate through storage, unfortunately there is no method for that.
There is currently no way to iterate a list of files in Firebase Storage using the Firebase SDKs. Instead, after you upload a file, you should also store its download URL in Firebase Realtime Database (or some other place) that you can query for the download URLs.
I was searching for a proper answer to this question for 2 days. What i found is, There is no proper API or Class in Firebase Storage for the same purpose. If you guys want to do the same effectively, get the files in your code programmatically and upload them to firebase storage through a loop. Through that you can get the download links after uploading of each files. Store it in the Real time Database of Firebase.
You can create a function that can can return a file. You can set up a /link url in the hosting to that function.
I am new to android. I would like to know how to retrieve stored images from a database. No add or delete functionality. I want to retrieve already stored images from a database. Please help me achieve this.
This answers assumes that you are retrieving images from a database in another app (because you'd already now how to retrieve images from a database that you created).
If the database is within another application, you must use a content provider. This link will redirect you to the official documentation. It covers all you will need to know about content providers.
In the most basic terms ever, to use a content provider you must first ask permission. Then you query the application that stores the database rather than the database itself (note: the application you query in turn queries the database). Therefore, you must have documentation that will provide predefined methods that must be used.
Not sure what really you want.
But if you finding a simple way to store image to database, you can try base64 image, it is like a string so simple store and read it in/from database.
To display base64 image on html, use can you
<img src="data:image/gif;base64,base64_data_here"/>
