Baidu provides an open interface for querying ip address locations. When you enter an ip address in the search box to search, the Baidu box application provided by ip138 will be opened, you can directly enter the ip address in the box to query.

3. Use aidl
The method 1 and 2 is analyzed here.
1. inherit the binder class
If your service is a private service of your application and runs in the same
