FileMetadata checksum
Is there something better than file size to use as a checksum?
Maybe Sha1 or MD5? I didn't see one on the FileMetadata class. It appears "Rev" changes even when the contents haven't changed (ie. on file rename)

The Dropbox API now offers a hash of file data that you can use to verify a file's contents. You can find it in FileMetadata.content_hash. It isn't a single MD5 or SHA1, but rather a combination of SHA256 hashes of the pieces of the file. You can find more information here:
https://www.dropbox.com/developers/reference/content-hash That is good news, is the content_hash available on the Java API?
- Greg-DB
Yes, in the official Dropbox API v2 Java SDK it's available as FileMetadata.contentHash.
Hi!
Is there any reason why content_hash, which was introduced in version 3.0.0, has been removed in version 3.0.1?ref. https://mvnrepository.com/artifact/com.dropbox.core/dropbox-core-sdk
- Greg-DBThanks for the report! I believe this is a known issue with the Java SDK release right now. The team is looking into it, and I'll follow up here once I have an update for you.
- Greg-DBThis should be fixed in the latest release of the SDK, v3.0.2. Please update and let me know if you're still seeing any issues.
I have now updated to version 3.0.2 and everything seems to work as expected. Thanks so much for your feedback.
