Question

I try to use a progress dialog. My code:

//Method to load data wire BT

private void dataload() {
    if(D) Log.e(TAG, "++ Data Load Function ++");

    // make discoverable
    Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
    discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
    startActivity(discoverableIntent);

    //Show Progress Dialog
    ProgressDialog dialog = ProgressDialog.show(BluetoothServer.this, "", "Loading, Please wait...", true);

    //Establish server connection
    mAcceptThread = new AcceptThread();
    mAcceptThread.run();

    //End progress dialog
    dialog.dismiss();

    //mAcceptThread.cancel();
}

Thats inside the main activity, and AcceptThread is in the same class, but extends Thread as a new class. The problem is, that no progress bar shows up.

Where is the problem, do I have to put the AcceptThread in another Activity?

Another problem is, that I get an ANR if the AcceptThread is called. I should be a problem, that it´s not running in the background, but why?

Hope you can help.

To start a thread, call the start() method, not run(), since run() will invoke the method on the current thread, while start() will create a new thread and invoke the run method in it. But looking at your code, seems like you need to use AsyncTask.
