我有一个广播接收器,它在注册时被触发(随后用onPause/onResume重新触发),这肯定是错误的行为？我错过了什么吗？

class FooActivity extends Activity {    

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        broadcastReceiver = new FooBroadcastReceiver();
        intentFilter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
    }

    @Override
    protected void onResume() {
        super.onResume();
        registerReceiver(connectivityReceiver, intentFilter);         
    }

    @Override
    protected void onPause() {
        super.onPause();
        unregisterReceiver(connectivityReceiver);
    }


class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {       
        if (connectivityAction(intent)) {
            Log.d("footag", "onReceive");
        }
    }

    private boolean connectivityAction(Intent intent) {
        return ConnectivityManager.CONNECTIVITY_ACTION.equals(intent.getAction());
    }

}
