关于android设备之间通信的问题

Question

device A is server, it has sqlite database.

device B, C and D is client, it don't have any database.

those devices i use serversocket,

InetAddress serverAddr = InetAddress.getByName(IP);
socket = new DatagramSocket(PORT, serverAddr);
byte[] buf = new byte[20];
DatagramPacket packet = new DatagramPacket(buf, buf.length);
socket.receive(packet);

so, my question is after connected. client device is able to access server device like fetchdata() in database? if can, then how to access?

Last but not least, i want to ask the wifimanager that allow multiple client access at a time should declare like what and should place the code at where?

Concerning your question about SQLite, SQLite is not meant to be used in the way you described. See Connect to a remote sqlite3 database with Python for further information.
