Android BufferedReader missing some letter

BufferedReader in = new BufferedReader(new InputStreamReader(
        socket.getInputStream()));
System.out.print("Received string: '");

while (!in.ready()) {

}

int result = in.read();
// String result1=in.readLine();
char[] buf = new char[50];

in.read(buf);

String b = new String(buf);
text.setText(b);

I sent the word "hello world" from the server but what I got back is "ello world" from the above code . It's missing the first letter h. I used read instead of readLine because readLine doesn't work, it crashed.

Another issue, hello world is displayed in 2 lines instead of one. layout for textview is wrap_content.

BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
System.out.print("Received string: '");
String inputLine;
String b = "";
while ((inputLine = in.readLine()) != null)
{
 b = inputLine;
 System.out.println(b);
 //or do whatever you want with b
}

With this you will also be able to read multiple lines (in case you reveived more than one)...

I used read instead of readLine because readLine doesn't work, it crashed.

It should not crash...i suggest you should fix this first

This line is consuming the first character:

int result=in.read();

Hence when you do this, buf will not contain it:

in.read(buf);

You can use the mark() and reset() functions on the buffered reader if you need to go back to the beginning. Or otherwise just comment out that line.
