read end of response in java readLine()

Question

    try {
                    input = new BufferedReader(new InputStreamReader(
                            mSocket.getInputStream()));
                    while (!Thread.currentThread().isInterrupted()) {
                        String messageStr = null;
                        messageStr = input.readLine();
                        if (messageStr != null) {
                            updateMessages(messageStr, false);
                        } else {
                            break;
                        }
                    }
                    input.close();
                } catch (IOException e) {
                    Log.e(CLIENT_TAG, "Server loop error: ", e);
                }

I am using the above code in a thread for receiving responses from socket connection.
In Android it works correctly as I used out.println() for sending data, but when the device is connected to ios and starts to receive data it cannot identify the end and is only received when the connection is closed. Is there any alternative methods other than readLine() and how to use in the above code.

Have a look at [how to identify end of inputstream in java](http://stackoverflow.com/a/5562415/4935567) and I think you will solve your problem. — Masked Man, Aug 08 '16 at 13:04

This would work better.

try 
{
    input = new BufferedReader(new InputStreamReader(mSocket.getInputStream()));
    String messageStr = "";
    while (!Thread.currentThread().isInterrupted() && (messageStr = input.readLine()) != null) 
    {
        updateMessages(messageStr, false);
    }
    input.close();
} catch (Exception e) {
     Log.e(CLIENT_TAG, "Server loop error: ", e);
}
