当应用程序关闭或销毁时，我如何才能收到短信到我的应用程序

Question

我正在开发一个短信应用程序，它几乎完成并运行良好，但它只在应用程序打开或在后台运行时收到消息，一旦我关闭我的应用程序就停止接收消息。

清单

<receiver
        android:name=".SmsBroadcastReceiver"
        android:enabled="true"
        android:exported="true"
        android:permission="android.permission.BROADCAST_WAP_PUSH">

        <intent-filter android:priority="999" >

            <action android:name="android.provider.Telephony.WAP_PUSH_DELIVER" />
            <data android:mimeType="application/vnd.wap.mms-message" />

        </intent-filter>
</receiver>

<service android:name=".ServiceCommunicator"
            android:enabled="true"
            android:exported="true"
            android:permission="android.permission.SEND_RESPOND_VIA_MESSAGE">

         <intent-filter>
             <category android:name="android.intent.category.DEFAULT" />
             <action android:name="android.intent.action.RESPOND_VIA_MESSAGE" />
             <data android:scheme="sms" />
             <data android:scheme="smsto" />
             <data android:scheme="mms" />
             <data android:scheme="mmsto" />
         </intent-filter>
   </service>

service.java

public class ServiceCommunicator extends Service {

SmsBroadcastReceiver mSmsBroadcastReceiver;
IntentFilter mIntentFilter;


@Override
public void onCreate() {
    super.onCreate();

    mSmsBroadcastReceiver=new SmsBroadcastReceiver();
    mIntentFilter=new IntentFilter();

    mIntentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");

    registerReceiver(mSmsBroadcastReceiver,mIntentFilter);
}

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

    unregisterReceiver(mSmsBroadcastReceiver);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    return super.onStartCommand(intent, flags, startId);
}

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

在MainActivity.java中，我通过调用它来启动服务：

StartService(new Intent(this,ServiceCommunicaor.class));
