You can assume the squares on the chess board are one

Android Independent Volume Control

由 时间秒杀一切 提交于 2019-12-31 03:52:05

I need to show the client when they reach 68m3 so they know they have filled a container. And is there a way to flash up a message if a client tries to submit an order less than 68m3 indicating to them that they still
