蓝牙扫描时不调用Android BroadcastReceiver

Question

broadcastreceiver我遇到了一个可怕的问题。当我想扫描bluetooth我的周围，但我发现广播接收器没有被调用。我怀疑这种情况发生在我的Android版本，即api 23，如https://code.google.com/p/android/issues/detail?id=190188所示。当我在移动电话中运行我的应用程序时没有问题，其中apis低于23 这是我的代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    // take an instance of BluetoothAdapter - Bluetooth radio
    BluetoothManager manager = (BluetoothManager)getApplicationContext().getSystemService(Context.BLUETOOTH_SERVICE);
    myBluetoothAdapter = manager.getAdapter();
    if(myBluetoothAdapter == null) {
        onBtn.setEnabled(false);
        offBtn.setEnabled(false);
        listBtn.setEnabled(false);
        findBtn.setEnabled(false);
        text.setText("Status: not supported");

        Toast.makeText(getApplicationContext(), "Your device does not support Bluetooth",
                Toast.LENGTH_LONG).show();
    } else {

        text = (TextView) findViewById(R.id.text);
        onBtn = (Button)findViewById(R.id.turnOn);
        onBtn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

        offBtn.setOnClickListener(new View.OnClickListener() {
