Add UPnP / PCP(NAT-PMP) support to Android client
Issue generated from Tuleap's migration script. Originally submitted by: xccng (xccng)
UPnP and PCP(NAT-PMP) work better than many other NAT traversal methods, and it doesn't require periodic keepalive traffic. It can be used in almost all home WiFi environments.
Please add it to the Android client, or make it an optional plugin apk.
There're quite a few pure Java/Android libraries mentioned on https://github.com/offbynull/portmapper#what-alternatives-are-available
