一个块有多少内存？
How much memory is a block?
文档说 getAvailableBlocksLong() is the same as: http://www.tutorialspoint.com/unix_system_calls/statvfs.htm
的结果
是blocks == bytes吗？
回答你的问题：
Are blocks == bytes?
不完全是。
getAvailableBlocksLong() retrieves the number of blocks that are free on the file system and available to applications. Whereas getAvailableBytes 检索文件系统上空闲且可供应用程序使用的字节数。
根据问答， 与以下相关：
getAvailableBlocksLong() * getBlockSizeLong() = getAvailableBytes()
