Question

您好，我现在尝试了2天，我找不到从firebase获取下载网址的方法。但是，它没有提供图片网址，而是com.google.android.gms.tasks.zzu@d7f1843

这是我的代码   Uri resultUri = result.getUri（）;

            String current_user_id = CurrentUser.getUid();

            final StorageReference filepath = ImageStorage.child("profile_images").child(current_user_id +"jpg"); 

            filepath.putFile(resultUri).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onComplete(@NonNull Task<UploadTask.TaskSnapshot> task) {

                    if(task.isSuccessful()){

                        downloadImageUrl = filepath.getDownloadUrl().toString();       

                        UserDatabase.child("image").setValue(downloadImageUrl).addOnCompleteListener(new OnCompleteListener<Void>() {
                            @Override
                            public void onComplete(@NonNull Task<Void> task) {
                                if(task.isSuccessful()){

                                    ProgressDialog.dismiss();
                                    Toast.makeText(SettingsActivity.this, "Success",Toast.LENGTH_LONG).show();
                                }
                            }
                        });

                    }else{

                        Toast.makeText(SettingsActivity.this, "Nope",Toast.LENGTH_LONG).show();
                        ProgressDialog.dismiss();
                    }
                }
            });

        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {

            Exception error = result.getError();
        }
    }
}
