java - 找不到符号 STORAGE_PATH UPLOADS

Question

我正在尝试将图像上传到 firebase 我有以下代码会导致上述错误

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

我有使用此代码创建的类常量来定义 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，而且是导致错误的原因。
