We Keep Coding

Application becomes irresponsive on InputStream.read();

When the code reaches the InputStream.read(), the application becomes iresponsive.
I think maybe that is the case because the client code runs before the server code and it waits for the input.
Here is the server code
When login button is clicked then the case is "Send login details"(It sends the login details to the client) and if the id and password is correct then the case becomes**"Login successful". It is sending correct value in **output.readUTF();
public void doWork(String line) {
Connection conn = Main.getConnection();
switch (line) {
case "Send login details":
Main main = new Main();
String details = main.giveLoginDetails();
String id = " ";
String password = " ";
int i = 0;
while (details.charAt(i) != ' ') {
id = id + details.charAt(i);
i++;
}
try {
id = id.trim();
password = details.substring(i + 1);
System.out.println(id + " " + password);
output.writeUTF(id + " " + password);
}
catch (IOException e)
{
e.printStackTrace();
}break;
case "Login successful":
String getDet1 = "SELECT * FROM $t;";
if(su == 1)
getDet1 = getDet1.replace("$t", "Post1");
else
getDet1 = getDet1.replace("$t", "Post"+(su*10+1));
System.out.print(getDet1);
rs2 = stmt2.executeQuery(getDet1);
String d;
int dd;
for (int x = 0; x < ch; x++) {
rs2.next();
d = rs2.getString(2);
output.writeUTF(d);
System.out.println(d);
dd = rs2.getInt(3);
output.writeInt(dd);
System.out.println(dd);
d = rs2.getString(4);
output.writeUTF(d);
System.out.println(d);
d = rs2.getString(5);
// if(d == null) {
// output.writeUTF("null");
// System.out.println("null");
// }
// else
output.writeUTF(d);
// System.out.println(d+"not null ");}
}
}
catch (SQLException | IOException e) {
e.printStackTrace();
}
break;
}
}
Client code:- Another scene after the login scene.
It is the Initialize method of Initializable interface. Here i am reading the output but it hangs.

I am wondering the same code works well at java SE .
but in android it sends request to the server to run and stop but I cannot receive packets like in java SE . Thanks.

is.readUTF() not recieving message

For the chat program in android side I am sending message via DataInput stream as
Socket sck = new Socket();
sck.connect(new InetAddress("192.168.1.91",1500),2000);
if(sck.isConnected())
{
DataOutputStream os = new DataOutputStream(sck.getOutputStream());
os.writeUTf(msg);
System.out.println("Message sent");
}
and on the Server side My code is
ServerSocket serv = new ServerSocket(1500);
Socket sock = serv.accept();
DataInputStream is = new DataInputStream(sock.getInputStream);
String ans = is.readUTF();
System.out.println("Got"+ans);
But on server side it seems it does not received anything and still waiting for the message. But on client side It shows message sent.
Here is my full code.

Try to use something like this:
String message = "";
while (!"end".equals(message)) {
if (is.available() != 0) {
message = dis.readUTF();
System.out.println(message);
}
}
I checked this - working. Server must be up before client will send message.

Partial download nightmare in Java

The problem, however, is that the partial download never starts... I do not know why. I usually end up with no activity at all or with a 206 Not Supported error.
Other class that might interest you is the Sharable which contains singleton instances:
Sharable.java and Scheduler.java
How do I resume partial downloads ?
