android – 将registerReceiver用于非活动和非服务类

我正在尝试registerReceiver for BluetoothDevice事件,如ACTION_ACL_CONNECTED,ACTION_ACL_DISCONNECTED.

但是我使用registerReceiver的类没有扩展Activity类,也没有扩展service类 – 所以我将Context传递给该类并注册接收者如下

context.registerReceiver(ActionFoundReceiver,new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED));

context.registerReceiver(ActionFoundReceiver,new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECTED));

context.registerReceiver(ActionFoundReceiver,new IntentFilter(BluetoothDevice.ACTION_ACL_DISCONNECT_requESTED));

和处理事件如下

private final BroadcastReceiver ActionFoundReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context,Intent intent) {
        String action = intent.getAction();
        if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
            // do some stuff
        }
    }
};

但是当设备连接或断开连接时我无法跟踪是否意味着ActionFoundReceiver无法被调用

context.getApplicationContext().registerReceiver(ActionFoundReceiver,new IntentFilter(BluetoothDevice.ACTION_ACL_CONNECTED));
