Communication between Android simulator (JAVA) and C ++ socket

C ++ as the Client

The IP address used by the android simulator is "127.0.0.1". Using the PC port number, you must use the tool used by the android sdk to perform port ing before debugging the TCP connection of the simulator .. Use the abd tool under Tools in the Sdk and run E in the cmd window: \ install \ android \ Android \ android-sdk-windwows \ tools \ adb forward tcp: 12581 tcp: 31012 "the preceding directory is the directory where android sdk Tools is located. Depends on local conditions.
