The XT2 has two memory cards for storing visual and thermal sensor photos. Which means that in order to format one of them, first the corresponding sensor index needs to be called: DJISDKManager.getInstance().getProduct().getCameraWithComponentIndex(int index) index = 0 corresponds to the visual sensor index = 2 corresponds to the thermal sensor So if you want to format the SD card slotted in slot 1, the specific method is: DJISDKManager.getInstance().getProduct().getCameraWithComponentIndex(0).formatSDCard(CompletionCallback） XT2  slot 1 corresponds to the visual sensor XT2 slot 2 corresponds to the thermal sensor If there is no SD card in the corresponding card slot during formatting, an error will be reported: undefined Error XT2 Sensor Type XT2 SD Card Slot XT2 Component Index Visual Sensor 1 0 Thermal Sensor 2 1 -Lisa, DJI Developer Support
