Well, but will the read of InputStream blocked when there is no
incoming data?
I mean... for example:
I run the sock in specific thread, because those methods' call will
blocked. The code might like this:
/// This is the socket thread for checking data
while not stop:
data = read(); // if no incoming data, we will blocked here
The client program needs to check the data from sever, so it run a
loop to read data. And how about outgoing data? Can I send out going
data from another thread? like this.
// this is called from UI thread
void onClick() {
outputStream.write("hello baby!");
}
