android - 每当我尝试在 Android 设备上上传文件时出现 "No content provider"错误

Question

最近，我在尝试将文件上传到 Android 存储时遇到了问题。它在 Unity Editor 上运行得非常好，但是每当我在我的 Android 上运行它时，我都会收到这个错误:

System.AggregateException: Exception of type 'System.AggregateException' was thrown. Firebase.Storage.StorageException: No content provider: /storage/emulated/0/Android/data/com.Comp.App/files/Uploads/ppp/master.json

这是我用来将文件上传到存储的代码:

Firebase.Storage.StorageReference f_ref = storage_ref.Child(referencePath); 
print("Reference path: " + referencePath); 

// Upload the file 
f_ref.PutFileAsync(filePath) 
.ContinueWith((Task<StorageMetadata> task) => 
{ 
  if (task.IsFaulted || task.IsCanceled) 
  { 
  Debug.Log(task.Exception.ToString()); 
  print("Couldn't upload " + filePath); 
  // Uh-oh, an error occurred! 
  } 
else { 
  Firebase.Storage.StorageMetadata metadata = task.Result; 
  string download_url = metadata.DownloadUrl.ToString(); 
  Debug.Log("download url = " + download_url); 
} 
}); 

文件存储在取决于设备的持久文件路径中。我尝试故意上传一个不存在的文件路径，但我收到了“FileNotFound”异常，所以我确定我尝试上传的文件路径是正确的。

如果您能帮助我弄清楚这个异常的含义以及如何修复它，我将不胜感激。提前致谢!

改用 inputStream 和 putStream :

InputStream is = new FileInputStream(filePath);
f_ref.putStream(is).....;
