How to retrieve image url form Firebase storage for JSON Parsing?

Question

I was thinking about making View-pager in android. Which retrieves slider images from a server, so that I can change those slider images at any time. I know for this I have to pass an image URL in JSON format. But I am not understanding how to get those image urls so that I can pass those image URLs in JSON format.

I tried to store an image in Storage of the Firebase. I don't know if this is the right way or not? I uploaded this image on firebase storage below this image there is a storage location url can i use that storage location url in json?

Yes,You have stored it right.You can use following code to get download url:

Just replace path with your image path eg images/6401.jpg

final StorageReference ref = storageRef.child("path");
uploadTask = ref.putFile(file);

Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
    @Override
    public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
        if (!task.isSuccessful()) {
            throw task.getException();
        }

        // Continue with the task to get the download URL
        return ref.getDownloadUrl();
    }
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()) {
            //Your image url do something with it.
            Uri downloadUri = task.getResult();
        } else {
            // Handle failures
            // ...
        }
    }
});
