Pretty standard there too - see the java.net package:
http://code.google.com/android/reference/java/net/package-summary.html.
One thing to keep in mind is, if you are trying to connect to your
localhost for testing, say another process running locally - you have
to keep in mind that the emulator is running there too, so you can't
use "localhost" or "127.0.0.1." Use the non loopback IP of your host
for that type testing.
Here is an older example I used in an Android app on m5 - probably
still works the same, nothing Android specific really in it, but I
haven't tried it in 0.9 or 1.0 lately:
private void callSocket(final String socketData) {
String address = "192.168.0.12";
int port = 8889;
Socket socket = null;
BufferedWriter writer = null;
BufferedReader reader = null;
try {
socket = new Socket(address, port);
writer = new BufferedWriter(new
OutputStreamWriter(socket
.getOutputStream()));
reader = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
// send input terminated with \n
String input = socketData;
writer.write(input + "\n", 0, input.length() + 1);
writer.flush();
// read back output
String output = reader.readLine();
Log.d(Constants.LOGTAG, " " + CLASSTAG + " output - " +
output);
socketOutput.setText(output);
// send EXIT and close
writer.write("EXIT\n", 0, 5);
writer.flush();
} catch (IOException e) {
Log.e(Constants.LOGTAG, " " + CLASSTAG
+ " IOException calling socket", e);
} finally {
try {
writer.close();
} catch (IOException e) {
// swallow
}
try {
reader.close();
} catch (IOException e) {
// swallow
}
try {
socket.close();
} catch (IOException e) {
// swallow
}
}
}
