/*
* 这个类主要实现了以下功能：
采用单例模式，确保整个应用中只有一个BackupUtils实例。
定义了一系列表示备份和恢复状态的常量，方便在操作过程中返回状态信息。
通过内部类TextExport实现了将笔记数据按照特定格式导出到文本文件的功能，包括文件夹、笔记及其相关数据的导出，并且在导出过程中会根据外部存储的状态进行相应处理，如果外部存储不可用或获取打印流失败等情况会返回相应的错误状态。同时，还提供了生成导出文件的方法，确保文件在 SD 卡上的正确创建和存储路径的设置。
在使用过程中，可以通过getInstance方法获取BackupUtils实例，然后调用exportToText方法进行数据导出，并根据返回的状态判断导出是否成功，还可以获取导出文件的名称和目录信息。
请注意，代码中的Notes类及其内部的常量（如NoteColumns、DataColumns、DataConstants等）和资源字符串（如R.string中的相关字符串）应该是在其他地方定义的，这里假设它们已经正确导入和定义。同时，在实际应用中，可能需要进一步处理异常情况和优化代码逻辑。
