Te recomendamos que revises esta resolución en un entorno controlado antes de enviarlo a producción, un saludo.
Solución:
Consulte la documentación para obtener una URL de descarga.
Cuando usted llama getDownloadUrl()la llamada es asíncrona y debe suscribirse en una devolución de llamada exitosa para obtener los resultados:
// Calls the server to securely obtain an unguessable download Url
private void getUrlAsync (String date)
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
dateRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener()
@Override
public void onSuccess(Uri downloadUrl)
//do something with downloadurl
);
Esto devolverá una URL de descarga pública indescifrable. Si acaba de cargar un archivo, esta URL pública estará en la devolución de llamada exitosa de la carga (no necesita llamar a otro método asíncrono después de haberlo cargado).
Sin embargo, si todo lo que quieres es un String representación de la referencia, puede simplemente llamar .toString()
// Returns a Uri of the form gs://bucket/path that can be used
// in future calls to getReferenceFromUrl to perform additional
// actions
private String niceRefLink (String date)
// Points to the root reference
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("/" + date+ ".csv");
return dateRef.toString();
//Firebase Storage – Fácil de trabajar con cargas y descargas.

aquí estoy cargando y obteniendo la URL de la imagen al mismo tiempo…
