This is a deprecated SDK.

We made some changes to Firebase ML Kit to better distinguish the on-device APIs from cloud based APIs. "ML Kit"(without firebase branding) contains all the on-device APIs. Here's the migration guide from firebase mlkit to mlkit. All further improvements and new APIs will be released only with the new ML Kit.
