[DJI MSDK] 
addPointCloudStatusListener 
-> onIMUPreHeatStatusChange

-> onIMUPreHeatStatusChange Event : check the L1 camera preheating status.
※However, since the ("PREHEATING","PREHEAT_COMPLETED" ) event occurs only once, the status of the event cannot be known after the drone is activated.
Is there any way to know the L1 camera preheating value?
--------------------------------------------------------------------------

Lidar().addPointCloudStatusListener(new Lidar.DJIPointCloudStatusListener() {
    @Override
    public void onPointCloudRecordStatusChange(RecordingStatus recordingStatus) {

    }

    @Override
    public void onPointCloudRecordStatusRecordingTimeChange(long l) {

    }

    @Override
    public void onIMUPreHeatStatusChange(DJILidarIMUPreheatStatus djiLidarIMUPreheatStatus) {
        switch (djiLidarIMUPreheatStatus) {
            case PREHEATING:
                break;
            case PREHEAT_COMPLETED:
                break;
        }
    }
});

  You can call flightControllerState.isIMUPreheating to know if the IMU preheating is completed.

  This pre-heating will only work once once you have switched on your aircraft. After this is done, then you can use the L1 camera. It will not pre-heat again.
