找不到符号STORAGE_PATH_UPLOADS

Question

我正在试图上传一个图像到firebase，我有下面的代码，它正在处理上面的错误

     //getting the storage reference
        StorageReference sRef = storageReference.child(SyncStateContract.Constants.STORAGE_PATH_UPLOADS + System.currentTimeMillis() + "." + getFileExtension(filePath));

使用此代码创建类常量来定义STORAGE_PATHS_UPLOADS

    package com.otemainc.thevendor;
     public class Constants {
     public static final String STORAGE_PATH_UPLOADS = "uploads/";
     public static final String DATABASE_PATH_UPLOADS = "uploads";
}

导致此错误的代码可能有什么问题？

Answer 1

只需删除SyncStateContract类，因为它不是必需的，是导致错误的那个类。
