Apps Help - quiting Thread, slow phone

[rhast]

Hello.

I'm new to android programming and this is my first project and would be very grateful if someone would take his time and help me out.
I've been making a bluetooth application which I have been testing on my phone (since I can't use emulator with bluetooth).
Everything works fine until I make a new AcceptThread and start it. (the code is from android bluetooth tutorial):

private class AcceptThread extends Thread {
    private final BluetoothServerSocket mmServerSocket;
 
    public AcceptThread() {
        // Use a temporary object that is later assigned to mmServerSocket,
        // because mmServerSocket is final
        BluetoothServerSocket tmp = null;
        try {
            // MY_UUID is the app's UUID string, also used by the client code
            tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME, MY_UUID);
        } catch (IOException e) { }
        mmServerSocket = tmp;
    }
 
    public void run() {
        BluetoothSocket socket = null;
        // Keep listening until exception occurs or a socket is returned
        while (true) {
            try {
                socket = mmServerSocket.accept();
            } catch (IOException e) {
                break;
            }
            // If a connection was accepted
            if (socket != null) {
                // Do work to manage the connection (in a separate thread)
                manageConnectedSocket(socket);
                mmServerSocket.close();
                break;
            }
        }
    }
 
    /** Will cancel the listening socket, and cause the thread to finish */
    public void cancel() {
        try {
            mmServerSocket.close();
        } catch (IOException e) { }
    }
}

When I run an app for the first time everything seems to work fine. But when I try to
rerun it with eclipse the phone freezes or it gets very slow and I have to restart the phone.
I've tried to:
- uninstall the app after the first run, but during uninstall process the phone gets slow and it stays slow until reset.
- force close the app with task manager (it does kill it, but the phone is slow again).
- use the cancel() from AcceptThread in onDestroy(), same result.

I don't have any log, since the problem appears before the application reruns.

Apparently the problem was not related to Thread, but in not turning the bluetooth off before quitting the application.
