I copy simplebluetooth class on readme.md to a new project

import android.app.Activity;
import android.bluetooth.BluetoothDevice;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends Activity {

    private SimpleBluetooth simpleBluetooth;
    private static final int SCAN_REQUEST = 119;
    private static final int CHOOSE_SERVER_REQUEST = 120;
    //...other code....//
    private String curMacAddress;

    @Override
    protected void onResume() {
        super.onResume();
        simpleBluetooth = new SimpleBluetooth(this, new SimpleBluetoothListener() {

            @Override
            public void onBluetoothDataReceived(byte[] bytes, String data) {
                //read the data coming in.
            }

            @Override
            public void onDeviceConnected(BluetoothDevice device) {
                //a device is connected so you can now send stuff to it

            }

            @Override
            public void onDeviceDisconnected(BluetoothDevice device) {
                // device was disconnected so connect it again?

            }

        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        } else if (id == R.id.scan) {
            simpleBluetooth.scan(SCAN_REQUEST);
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
