Data sent via Bluetooth turns up multiple times while new data continue to be received

Question

I'm trying to build an android client application that sends data regarding gestures that the user performs, to a Java server, using Bluetooth. When the user performs a gesture, the app sends data about it to the pc.
For example (android client send) 5:-24:2, (java server receive) 5:-24:2.
As long as the gestures are performed long range between themselves, the code works fine.

The problem is when the app sends data very fast (because the user perform a scroll for example, so onScroll(...) called for each onTouchEvent(...)).
Then a specific message gets stuck:

(android client send) 5:-24:2, (java server receive) 5:-24:2 (ok)
(android client send) 5:-24:2, (java server receive) 5:-24:2 (ok)
(android client send) 5:-24:2, (java server receive) 5:-24:25:-24:2 (message stuck)
(android client send) 5:-24:2, (java server receive) 5:-24:25:-24:2 (message stuck)
...

The java server side read code:

private StreamConnection mConnection;
public void run() {
    try {
        InputStream inputStream = mConnection.openInputStream();
        System.out.println("waiting for input");
        byte[] buffer = new byte[BUFFER_SIZE];

        while (true) {
            inputStream.read(buffer);
            String command = new String(buffer).trim();
            System.out.println(command);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

The android client write side:

    private final OutputStream mmOutStream;
    String msg = "5:-24:2";
    byte[] msgByte = msg.getBytes();
    mmOutStream.write(msgByte); 

Answer 1

One major error I did was to use the same buffer while inputStream.read(buffer) received data in varied lengths.
I did the following change and that solved many of the problems.

  int length;
  while (true) {
        length = inputStream.read(buffer);
        String command = new String(buffer, 0, length);
        System.out.println(command);
    }
