Question

我在后台创建了一个上传数据的服务。如果没有Internet连接，我想注册正在等待Internet连接的广播接收器，然后再次启动服务。我的问题：

广播接收器从应用程序开始。我不想要这个。广播接收器应该是非注册的，直到服务注册它。我怎么能这样做？

任何人都可以发布代码示例如何注册从服务中注销Receiver吗？

在服务中注册接收器和取消注册接收器的示例代码。

public class CallDetectService extends Service {
    BroadcastReceiver phoneCallreceiver;
    Calendar futuretime=Calendar.getInstance();

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);
        Log.v("ranjith","Inside onstartcommand of calldetectservice");

        phoneCallreceiver = new PhoneCallreceiver();

        registerReceiver(phoneCallreceiver, intentFilter);


        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        Toast.makeText(getApplicationContext(), "Service destroy called", Toast.LENGTH_LONG).show();
        Log.v("ranjith", "stopped the service");
        if (phoneCallreceiver != null) {

            unregisterReceiver(phoneCallreceiver);
            Log.v("ranjith", "Unregistered receiver");
        }
        super.onDestroy();
    }

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