  • Your question is to broad, please read the raspberrypi.stackexchange.com/help/how-to-ask – MatsK Feb 5 at 15:08
  • Have you bothered looking in the playstore for Raspberry Pi associated apps? There are some fairly complex, feature rich, configurable, etc. things there that might do. If you want to write your own, this is really a question about network programming fundamentals. Please do not bother asking anyone to regurgitate that kind of information here -- there must be hundreds of thousands if not millions of pages online and in print about this. You need to do a bit of reading about how computers communicate on a network. Both Android and the Pi are very normal in this sense. – goldilocks Feb 15 at 14:39
