Answer 1

您可以改用Task<Uri>，尝试一下。不建议使用此getMetadata().getReference().getDownloadUrl()，建议您阅读此Upload-files firebase

photoReference.putFile(uriImagen).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Task<Uri> downloadUri = taskSnapshot.getStorage().getDownloadUrl();

           if(downloadUri.isSuccessful()){
            String urlPhoto = downloadUri.getResult().toString();
            Log.v("Url de la foto", urlPhoto);
            Message m = new Message(tvName.getText().toString() + " te ha enviado una foto", urlPhoto, tvName.getText().toString(), "", "2", "00:00");
                    databaseReference.push().setValue(m);
        }}
    })
    .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            //Do whatever you want                     
        }
    });

尝试此代码：

public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

            Task<Uri> downloadUrl = taskSnapshot.getStorage().getDownloadUrl();
            downloadUrl.addOnCompleteListener(new OnCompleteListener<Uri>() {
                @Override
                public void onComplete(@NonNull Task<Uri> task) {
                    Log.v(TAG, "Media is uploaded");

                    String downloadURL = "https://" + task.getResult().getEncodedAuthority()
                            + task.getResult().getEncodedPath()
                            + "?alt=media&token="
                            + task.getResult().getQueryParameters("token").get(0);

                    Log.v(TAG, "downloadURL: " + downloadURL);
                    //save your downloadURL
                }
            });
        }
