Runnable,RBCWrapperDelegate
DownloadManager downloads a large file from a server. If the file is splitted
into several chunks, it downloads them separately and merges them altogether
again. Each chunk is checked against its content length provided by HTTP. The
whole downloaded file is checked against the CRC checksum which is stored in
the file with file extension crc.
Download file consists of:
Download file consists of:
<chunk>.001 <chunk>.002 ... <chunk>.<N> <file>.crc(where the chunks will be merged to <file>.<ext>) or
<file>.<ext> <file>.crcCRC file contents:
filename=<file>.<ext> size=<fileSizeInBytes> crc32=<8DigitsHexCRC32>
