CameraX crash: "The selected camera does not support the enabled use cases"

[Kanhaiya]

Hi CameraX team,

We're seeing an intermittent production crash with LifecycleCameraController:

IllegalStateException: The selected camera does not support the enabled use cases. Caused by: IllegalArgumentException: No available camera can be found.

The crash occurs while calling setCameraSelector() and CameraX fails to bind the use cases.

Has anyone encountered this issue? Under what conditions can CameraX report "No available camera can be found" even though the device has cameras? Are there known device-specific issues or recommended recovery strategies (retry, unbind/rebind, checking concurrent use cases, etc.)?

Any guidance would be greatly appreciated. Thanks!

Hi,

The default CameraSelector of CameraController is CameraSelector#DEFAULT_BACK_CAMERA. Could you check whether the device has back camera? You may need to have some code to explicitly set CameraSelector#DEFAULT_FRONT_CAMERA to the CameraController if the device has only front camera and your app want to run with front camera when launching.

User have all camera. 75% crash comes on Android 16 (V2439). LOG reads Cams:0 with no per-camera Id:/Lens: entries — so the camera set handed to select() was empty. CameraX found zero cameras at bind time, not "a device without a back camera." And LensFilter:0 is LENS_FACING_FRONT (LENS_FACING_FRONT = 0, BACK = 1), so the failing call was a switch to the front camera. A front-only device would log Cams:1 Id:1 Lens:0 with LensFilter:1. Cams:0.
