android - 在哪里注销 BroadcastReceiver(在服务中)？

Question

我有一个在服务中动态创建的 BroadcastReceiver。其目的是检测 SMS 何时发送。它按预期工作。

我的问题是我收到一条错误消息“Intent Receiver has leaked”。我是否错过了对 unregisterReceiver() 的调用？

我正在 onDestroy() 中调用 unregisterReceiver()。我想这一定是错误的。我应该在哪里注销接收器？

代码...

public class MyService extends Service {
    BroadcastReceiver brSms;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
    }

    @Override
    public void onStart(Intent intent, int startid) {
        //Define the receiver
        brSms = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                //Do some  stuff
            };
        }

        registerReceiver(brSms, new IntentFilter(SENT_SMS_ACTION));
    }

    @Override
    public void onDestroy() {
        unregisterReceiver(brSms);
        Toast.makeText(this, "onDestroy has been called", Toast.LENGTH_SHORT).show();
    }
}//end of MyService

像这样尝试:

public class MyService extends Service {
    BroadcastReceiver brSms;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        brSms = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                //Do some  stuff
            }
        };

        registerReceiver(brSms, new IntentFilter(SENT_SMS_ACTION));
    }

    @Override
    public void onStart(Intent intent, int startid) {
    }

    @Override
    public void onDestroy() {
        unregisterReceiver(brSms);
        Toast.makeText(this, "onDestroy has been called", Toast.LENGTH_SHORT).show();
    }
}
