I'm trying to code a TCP client in android java. Most works fine. But i have one issue. If the socket is connected and the remeote host shuts down or the network goes down or something else, the socket.getinputstream keeps blocking.
I don't know if the socket is still connected. I code in objective-c too and in objective-c i get an event that the socket forcefully shuts down and i can try to reconnect. So on objective c the socket tracks the state.
In java the socket and the inputstream is still connected or blocked even the socket is down. How can i check if the socket is still connected?
@Override
protected Void doInBackground(String... params) {
try {
String host = params[0];
int port = Integer.parseInt(params[1]);
SocketAddress sockaddr = new InetSocketAddress(host, port);
Socket socket = new Socket();
socket.connect(sockaddr,5000);
socket.setSoTimeout(7000);
out = new PrintWriter(socket.getOutputStream(), true);
mBufferIn = new BufferedReader(new InputStreamReader(socket.getInputStream()));
while (mRun) {
try {
-----> mServerMessage = mBufferIn.readLine();
}catch (Exception e){
Log.d("my","hier3" + e.getMessage());
}
if (mServerMessage.trim() != null) {
sender.messageReceived(s2);
}else{
}
}
}
} catch (UnknownHostException e
) {
