mapbox
OpenCL 3.0 Support
I have a Samsung Galaxy Tab S6 Lite. I was able to get the MapBox Vision SDK working on this tablet with Android 11. However after updating the tablet to Android 12 I get the following errors in the log when using the MapBox Vision SDK:
01-24 09:57:30.707 32678 8876 I MACE : mace.cc:539 Initializing MaceEngine

From the error message it appears that the MapBox Vision SDK is using the XiamMi/mace Mobile AI Compute Engine library and is using an older version (v0.11.0-rc0-241-gc0c4f29) that does not support OpenCL 3.0. It looks like version 1.1.1 of mace (release January 13 2022) does add OpenCL 3.0 support: https://github.com/XiaoMi/mace/releases/tag/v1.1.1
Another issue I ran into with the Android 12 update is that the MapBox libraries use a PendingIntent to launch telemetry but the version of the MapBox libraries used by vision do not have updates to support this android 12 change: https://developer.android.com/about/versions/12/behavior-changes-12#pending-intent-mutability
I was able to work around this by targeting a pre-android 12 SDK version, but it would be nice to have a vision library that worked with the latest android releases.
