I have created an activity called ASAPExampleTCPEncounterActivity.
This activity enables establishing a TCP/IP connection to ASAPPeers within the same TCP/IP network as the ASAPAndroidPeer.
The target ASAPPeer should provide a TCP ServerSocket to which ASAPAndroid can connect.
For this purpose, I have added the package tcpEncounter. Inside this package there is the class TCPEncounterManagerApplicationSide.java for triggering the establishment of the TCP/IP connection to the target peer on app side. On service side there is the class TCPClientSocketThread which starts a thread for establashing a TCP connection to a ServerSocket and passes the sockets to an EncounterManager.
However, when establishing the TCP/IP connection to a target peer, the following StackOverflowError occurs:
