我可以注册一个广播接收器，然后在另一个活动中注销它吗？- Android

private BroadcastReceiver myReceiver = new MyReceiver(); // 自定义广播接收器

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

    IntentFilter filter = new IntentFilter();
    filter.addAction("com.example.MY_ACTION"); // 指定您感兴趣的广播类型

    registerReceiver(myReceiver, filter); // 注册广播接收器
}

@Override
protected void onDestroy() {
    super.onDestroy();

    unregisterReceiver(myReceiver); // 注销广播接收器
}
