android - Firebase 存储 IO 异常

Question

我一直在尝试从 Firebase Storage 下载 PDF 文件并将其存储在本地存储中，而不是外部存储中。

发生异常：

com.google.firebase.storage.StorageException：发生未知错误，请检查 HTTP 结果代码和服务器响应的内部异常。

下载文件并存储的代码：

        FirebaseStorage storage = FirebaseStorage.getInstance();
        StorageReference storageRef = storage.getReferenceFromUrl(fileDetails.getFileUrl());

        File rootPath = new File(Environment.getDataDirectory(), "notesApp");
        if (!rootPath.exists()) {
            rootPath.mkdirs();
        }

        final File myFile = new File(rootPath,fileDetails.getFileName()+".pdf");

        storageRef.getFile(myFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot) {
                // Local temp file has been created
            }
        }).addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception exception) {
                // Handle any errors
                Log.e("Download Failed: ",exception.toString());
            }
        });

Logcat 异常：

编辑：

替换 File rootPath = new File(Environment.getDataDirectory(), "notesApp"); 为 File rootPath = new File(getBaseContext().getFilesDir(), "notesApp");

现在唯一显示的错误是：

error getting token java.util.concurrent.ExecutionException: com.google.firebase.internal.api.FirebaseNoSignedInUserException: Please sign in before trying to get a token.
