应用程序被终止时Android中的FCM通知

我正在尝试使用此链接将推送通知（FCM）发送到我的android应用程序。当应用程序处于后台时，一切正常，但一旦我杀死应用程序，我就不会收到任何声名。我使用android 7.1操作系统的Lenovo Tab。我还尝试将应用程序签名并作为APK安装。下面是我的gradle文件和logcat输出：-

        <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize"
        android:exported="true">

</application>

正如您从logcat中看到的，我理解权限未被授予，但我在gradle文件中添加了权限。我是否仍然缺少有关权限的内容
