Outside the I2C port, XBee modules create a distributed wireless sensor network that reports back to a Raspberry Pi.
If you want to interact with your Rasp Pi through your Android cellphone or tablet, we have two articles that can help. In one article, the WebSocket protocol, which lets you set up communications over TCP, is used to create a Raspberry Pi server and an Android client.
