In my app when I use dataoutputstream without button it works but when I use it with button it crashes!
I've needed permissions in manifest. At first dataoutputstream works but when I use button it crashes.
private DataOutputStream outputStream;
final Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
socket = new Socket(ip,9000);
log("Connected!");
outputStream = new DataOutputStream(socket.getOutputStream());
outputStream.write("hi server\n".getBytes());
}
catch (IOException e) {
log("Not Connected!");
}
}
});
btn_send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (outputStream == null) {
return;
}
String message = txt_user.getText().toString() + "\n";
try {
outputStream.write(message.getBytes());
} catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
