如何解决 java.lang.IllegalStateException: 任务尚未完成将图像上传到 Firebase 存储时出错？

Question

将 firebase 存储更新到最新版本 16.0.1 后，我开始出现此错误。我没有更改代码中的任何内容我只是在升级 gradle 构建依赖项后收到此错误

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


            if (task.isSuccessful()) {
                Uri downloadUri = task.getResult().getStorage().getDownloadUrl().getResult();

                if (downloadUri == null)
                    return ;


                downloadUriArray.add(String.valueOf(downloadUri));

                singleAdImageArrayList.get(uriIndex).setUploading(false);
                singleAdImageArrayList.get(uriIndex).setImgDownloadUri(downloadUri);
                singleAdImageArrayList.get(uriIndex).setSent(true);
                singleAdImageArrayList.get(uriIndex).setHasLocalUri(false);
                sendImagesUpdateToActivity();

                checkCompletion();

                Toast.makeText(getApplicationContext(), "sent successfully", Toast.LENGTH_LONG).show();
                return ;

            }else {

                singleAdImageArrayList.get(uriIndex).setUploading(false);
                singleAdImageArrayList.get(uriIndex).setFailUploading(true);
                sendImagesUpdateToActivity();

                failuresCounter++;
                if (task.getException() != null && task.getException().getMessage() != null) {
                    Log.d(TAG, "onComplete: failed exception: " + task.getException().getMessage());
                    QuickToastUtil.makeToast(getApplicationContext(), getString(R.string.network_error), false);
                }

                checkCompletion();

                return ;
            }

        }
    });

我想通了，不知道上传任务api已经改变了一点，它使用continuation来检索下载uri，如下所示：

final StorageReference imagesRef= storageRef.child("images/my_image.jpg");
urlTask = imagesRef.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 imagesRef.getDownloadUrl();
            }
        }).addOnCompleteListener(new OnCompleteListener<Uri>() {
            @Override
            public void onComplete(@NonNull Task<Uri> task) {
                if (task.isSuccessful()) {
                    Uri downloadUri = task.getResult();
                    if (downloadUri == null)
                        return ;
                    else
                    doWhateverYouWant(downloadUri);

       }
        });
