New features

  • On Android, added a “thin” variant of Image Labeling API, backed by Google Play Services. Reduces size impact to your app by ~3 MB compared to the bundled variant.

Improvements and bug fixes

  • Breaking change: Split Pose Detection into two libraries for size optimization. One library only bundles the fast models, while the other only bundles the accurate models. This helps save the application size, if you only use one set of the models. Same change happened to iOS: The PoseDetection pod now contains only the fast models. To use the accurate models, use the PoseDetectionAccurate pod instead.
  • On iOS, fixed a memory leak which occurred during pose detector deallocation.

New features

  • Added the Pose Detection API, a CPU Based, lightweight and versatile solution for developers to track a user’s physical actions in real time within their apps. Pose Detection offers a 33 point skeletal match (with hands and feet tracking) of a users body in real time and has been tuned to work well for complex athletic use cases.

    Pose detection also works fully offline, comes with two operating modes (fast and accurate), and supports both Android and iOS.

New features

  • Added a new Digital Ink Recognition API that recognizes text and shapes handwritten on a digital surface (e.g. touch screens). Supports 300+ languages, as well as emoji and autodraw. It is the same technology that powers handwriting recognition layouts in Gboard, the Google Translate apps and the Quick, Draw! game.

    Digital Ink Recognition works fully offline (aside from a one-time download of language packs), and supports both Android and iOS.

  • On Android, added support for specifying your own custom Executor for running expensive tasks like model loading and inference to Image Labeling and Object Detection and Tracking. With this release, all ML Kit APIs now support custom executors.

    By default, ML Kit uses a highly optimized, internally managed thread pool to run background tasks. This API can help with specialized use cases where developers want to keep full control over the threads in their app instead.

Improvements and bug fixes

  • On Android, for the Barcode Scanning API, fixed rotation handling of the input image.

July 15, 2020

This release includes improvements and bug fixes.

iOS: GoogleMLKit/Common 0.61.1

Improvements and bug fixes

  • Upgraded the version range of GoogleDataTransport dependency in MLKitCommon from 3.2 or higher to 7.0 or higher.
  • Removed the GoogleDataTransportCCTSupport dependency from MLKitCommon.

New features

  • The Image Labeling and Object Detection and Tracking APIs now support float-based custom models.
  • On Android, added support for specifying your own custom Executor for running expensive tasks like model loading and inference to all APIs except Image Labeling and Object Detection and Tracking.

    By default, ML Kit uses a highly optimized, internally managed thread pool to run background tasks. This API can help with specialized use cases where developers want to keep full control over the threads in their app instead.

Improvements and bug fixes

  • Breaking change: On iOS, for the Barcode Scanning API, fixed a typo in BarcodePersonName and renamed its pronounciation property to pronunciation.
  • Fixed an issue on iOS in the Translate and Smart Reply APIs where the app would crash if the device locale does not specify a region (e.g. "en" instead of "en-US").

June 3, 2020

Android: 16.0.0 / iOS: 0.60.0

This is the first release of ML Kit as a standalone SDK, independent from Firebase. This SDK offers all the on-device APIs that were previously offered through the ML Kit for Firebase SDK. For more information on this change and instructions on migrating your existing apps, please follow our migration guide.

This release includes new features, improvements and bug fixes.

New features

Improvements and bug fixes

  • On Android, included support for Face Contours in “thin” variant of Face Detection API, backed by Google Play Services. Reduces size impact to your app by ~20.3 MB compared to bundled variant.
  • On Android, improved CameraX and Camera2 performance for Barcode Scanning and Face Detection APIs by moving image processing code from Java to native code.
  • Android Jetpack Lifecycle support has been added to all APIs. Developers can use addObserver to automatically manage the initiation and teardown of ML Kit APIs as the app goes through screen rotation or closure by the user / system. This makes CameraX integration easier.
  • Text Recognition API: the most prevalent recognized language is now provided
  • Face Detection API: the Euler X angle of a face is now provided
  • Barcode Scanning API [bundled]: added support for broken PDF417 start/stop pattern detection, improving recall by 10%
  • Object Detection and Tracking API: updated localizer model, improving average precision and reducing footprint by ~700KB

Legacy releases

Changes prior to June 3, 2020 can be found in the Firebase release notes.
