Use P2P for easy offline sharing/syncing about robot-scouter HOT 4 CLOSED

Sigh. Apparently, all of the nearby stuff only works if you are connected to the internet. 😢 I guess I'll have to rough it up and deal with sockets, raw bytes, and whatever else lies in this mess: https://github.com/googlesamples/android-BluetoothChat/blob/master/Application/src/main/java/com/example/android/bluetoothchat/BluetoothChatFragment.java

Ok, so I looked into this and it actually doesn't seem too hard at all. However, I tested what would happen if someone overwrites a value in the db while offline and unfortunately, the winner is the last device to connect to the internet not the one who wrote to that location last. This would make it highly probable that scouting data would be lost if people use this feature. Therefore, out of an abundance of caution, I'm not going to develop this feature.

There could however be a possibility of just using P2P for exporting an up to data spreadsheet, but I feel like the whole thing would result in bad UX so I'll wait until someone asks for this feature.
