Many friends said before that they need map navigation software (GPS), but it is only supported by smart phones, so I can only find a map navigation software that is easier to use on the JAVA platform. It has a large screen resolution of 240*320 and is suitable for most Java platform models. , let's talk about the functions: Wanwan Map provides map search, bus, taxi, driving and other services. Its map coverage includes 31 provinces and municipalities (excluding Hong Kong, Macao, and Taiwan), a total of 1,120 cities and regions (counties/cities), and contains more than 13 million information points. It is a good helper in your life. If you need it, you can try it. Let friends who don't have smartphones also have their own mobile phone navigation! (The software is completely free)
