java - 在“FirebaseFirestore”中，保存的不是图片链接，而是一些难以理解的内容

Question

单击setupBtn保存以下内容com.google.android.gms.tasks.zzu@9138f83而不是图像链接。

我认为整个问题都在这一行 Uri download_uri = Uri.parse(task.getResult().getMetadata().getReference().getDownloadUrl().toString());

告诉我问题是什么以及如何解决它。

为了解决这个问题，我将代码固定到这个：

image_path.putFile(mainImageURI).addOnCompleteListener(task -> {
                    if (task.isSuccessful()) {
                        image_path.putFile(mainImageURI).addOnSuccessListener(taskSnapshot ->
                                image_path.getDownloadUrl().addOnSuccessListener(uri -> {

                                    String downloadUrl = uri.toString();

                                    Map<String, String> userMap = new HashMap<>();
                                    userMap.put("name", user_name);
                                    userMap.put("image", downloadUrl);

                                    firebaseFirestore.collection("Users").document(user_id).set(userMap).addOnCompleteListener(task1 -> {
                                        if (task1.isSuccessful()) {

                                            Toast.makeText(SetupActivity.this, "Update", Toast.LENGTH_LONG).show();
                                            Intent mainIntent = new Intent(SetupActivity.this, MainActivity.class);
                                            startActivity(mainIntent);
                                            finish();

                                        } else {

                                            String error = task1.getException().getMessage();
                                            Toast.makeText(SetupActivity.this, "Firestore Error" + error, Toast.LENGTH_LONG).show();

                                        }

                                        setupProgress.setVisibility(View.INVISIBLE);
                                    });

                                }));
                    } else {

                        String error = task.getException().getMessage();
                        Toast.makeText(SetupActivity.this, "Image Error" + error, Toast.LENGTH_LONG).show();

                        setupProgress.setVisibility(View.INVISIBLE);
                    }
                });
