NotificationListenerService不起作用-即使在授予权限后

问题描述

下面是我的捕获通知的代码.我不明白为什么 onNotificationPosted 没有被解雇.

Below is my code to capture notifications. I dont understand why the onNotificationPosted is not getting fired.

我正在通过设置">安全性"为我的应用程序授予通知"访问权限，同时还触发了MyNotifService的 onCreate ，但没有触发 onNotificationPosted .

I am giving my app Notifications access from Settings > Security and the onCreate from MyNotifService is also getting fired, but onNotificationPosted is not getting fired.

我想念什么或做错什么了?

What am I missing or doing wrong?

通过我的 MainActivity的onCreate()函数:

Intent intent = new Intent(this, MyNotifService.class);
this.startService(intent);

扩展 NotificationListenerService 的我的服务代码:

@SuppressLint("NewApi")
public class MyNotifService extends NotificationListenerService {

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        super.onNotificationPosted(sbn);
        Log.v("focus", "in onNotificationPosted() of MyNotifService");
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.v("focus", "in onCreate() of MyNotifService");
    }
}

在清单文件中，我有这个:

<service android:name="com.mavdev.focusoutfacebook.notifications.MyNotifService"
    android:label="@string/app_name"
    android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
    <intent-filter>
        <action android:name="android.service.notification.NotificationListenerService" />
    </intent-filter>
</service>

推荐答案

这似乎有些胡扯，但这是此例中的实际解决方法:

It does seem to be a bit flakey, but this is the actual fix in this case:

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