Adaptation Guide
Solution 1: Use display.on(‘foldStatusChange’) of the @ohos.display.d.ts module to listen for folding status changes of a foldable device.
When detecting such a change, use getSupportedCameras of the @ohos.multimedia.camera.d.ts module to obtain the camera information. Then select the camera to open based on the information.
The camera information obtained by getSupportedCameras is the same regardless of whether FoldStatus in the data returned through the callback display.on(‘foldStatusChange’) is FOLD_STATUS_HALF_FOLDED or FOLD_STATUS_EXPANDED.
Solution 2: Use CameraManager.on(‘foldStatusChange’) of the @ohos.multimedia.camera.d.ts module to listen for folding status changes of a foldable device.
When detecting such a change, FoldStatusInfo is returned, including the folding status of the device and the list of cameras supported in this status. You can select the camera to open based on the information.
