Question

In my app, I open a ServerSocket and listen for and handle connections like so:

while(isRunning) {
     try {
         socket = serverSocket.accept();
         new ThreadToHandleIt().start(socket);
     } catch (IOException e) {

     }
}

And then at the end (after I would set isRunning = false), I close the serverSocket, like so:

try {
    serverSocket.close();
} catch (IOException e) {

}

My question is: when I call serverSocket.close() at the end, will that automatically also close all the sockets I spawned off for handling? Or do I have to manually close all of them myself?

The dev guide at

http://developer.android.com/reference/java/net/ServerSocket.html#close%28%29

says

Closes this server socket and its implementation. Any attempt to connect to this socket ?thereafter will fail.

so going by the wording, you’ll have to close each socket individually
