java - 尝试上传使用 Android 扫描库扫描的图像时出现存储异常

Question

我正在尝试将扫描的文件（使用 android 文档扫描库）存储到 FirebaseStorage，但出现存储异常，我在线尝试了所有答案，但没有一个适合我。

我正在尝试将扫描的文件（使用 android 文档扫描库）存储到 FirebaseStorage，但出现存储异常，我在线尝试了所有答案，但没有一个适合我。我可以在firebase实时数据库中插入数据，但是当它调用函数上传文件时，我得到以下异常：

错误如下：

以下是上传文档的代码块：

// method to upload the document file only
private void uploadDocumentFile(){

    final StorageReference documentFileRef = FirebaseStorage.getInstance()
            .getReference(" Documents /");

    if(documentUri != null){

        documentFileRef.putFile(documentUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

               documentFileRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        // getting image uri and converting into string
                        Uri downloadUrl = uri;
                        documentUrl = downloadUrl.toString();
                    }
                });


            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                // display an error message
                Toast.makeText(applicationContext, " Failed : " + e.getMessage(), Toast.LENGTH_LONG).show();
            }
        }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
                        double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot
                                .getTotalByteCount());
                        progressDialog.setMessage("Uploaded "+(int)progress+"%");
                    }
                });;

    }


}

我想成功地将文件上传到存储。
