ARCore SDK for Android v1.24.0

New APIs and capabilities

• Added new Raw Depth API that provides a depth image without image-space filtering.
  • All devices that support the existing Depth API in ARCore supported devices now also support the new Raw Depth API.
  • Java: Developer guide, Frame#acquireRawDepthImage(), Frame#acquireRawDepthConfidenceImage(), Config.DepthMode.RAW_DEPTH_ONLY.
  • C: Developer guide, ArFrame_acquireRawDepthImage(), ArFrame_acquireRawDepthConfidenceImage(), AR_DEPTH_MODE_RAW_DEPTH_ONLY.
• Added new Custom Data Track Recording/Playback API, augmentations of the recording and playback features that allow developers to record and playback data to and from custom specified tracks, packaged as MP4 recordings.
  • Java: Developer guide, Track, Frame#recordTrackData(), Frame#getUpdatedTrackData().
  • C: Developer guide, ArTrack, ArFrame_recordTrackData(), ArFrame_getUpdatedTrackData().
• Added new trackable type DepthPoint that provides a calculated depth pose with each frame by hit testing. These values are sampled from the latest depth image, which yields more accurate results on non-planar or low-texture areas in the environment.

Deprecations

None

Other changes

• Java: Added new raw_depth_java sample app.
• Java: Updated hello_ar_java to use DepthPoint hit results from Frame#hitTest() when placing assets.
• C: Updated hello_ar_c to use ArDepthPoint hit results from ArFrame_hitTest() when placing assets.

Bug fixes
