onNotificationPosted从未调用过

Question

我正在尝试实现一个能够读取通知的功能，而且似乎我有一个错误，因为onNotificationPosted()的NotificationListenerService从未被调用过。我配置了清单，正确修改了安全设置，甚至手动启动了服务，但没有做任何事情。可以在模拟器中测试它不是最好的方法。

这是Notification getter类：

/**
* Created by laurentmeyer on 28/02/15.
*/
public class NotificationListener extends NotificationListenerService {
    public NotificationListener(){
        Log.d("Notification", "Created");
    }
@Override
public void onNotificationPosted(StatusBarNotification sbn) {
    Notification mNotification = sbn.getNotification();
    Intent intent = new Intent("Msg");
    Log.d("Notification", "Received");
    LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent);
}

@Override
public void onCreate() {
    super.onCreate();
    Log.d("Notification", "created");
}


@Override
public void onDestroy() {
    super.onDestroy();
    Log.d("Notification", "destroyed");

}

@Override
public void onNotificationRemoved(StatusBarNotification sbn) {
}
}

（抱歉不正确的缩进）

这是我应该响应广播的片段：

public class VerificationFragment extends BaseFragment implements SMSReceivedCallbacks {
    public void onNotificationReceived(int code) {
        ed.setText("OK");
}


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LocalBroadcastManager.getInstance(getActivity()).registerReceiver(new Receiver(), new IntentFilter("Msg"));
}
// A bunch of other useless stuff


private class Receiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        onNotificationReceived(0);
    }
}
}

清单：

<service
        android:name=".NotificationListener"
        android:label="@string/service_name"
        android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE" >
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" />
        </intent-filter>

总结一下，我有：

02-28 11:40:53.236    6585-6585/com.******.laurentmeyer.****** D/Notification﹕ Created
02-28 11:40:53.236    6585-6585/com.******.laurentmeyer.****** D/Notification﹕ created

然后什么也没有。我已经看过SO上的所有线程，但可能会遗漏一些非常简单的东西。

在您的设置中启用通知访问权限：

if (Settings.Secure.getString(this.getContentResolver(), "enabled_notification_listeners").contains(getApplicationContext().getPackageName())) {
            //Add the code to launch the NotificationService Listener here.
        } else {
            //Launch notification access in the settings...
            getApplicationContext().startActivity(new Intent(
                    "android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"));
        }
