Я использую этот сервис для получения широты и долготы, но когда я закрываю приложение, я не могу получить обновленную широту и долготу.

вот мой манифест 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.kanwarpreet.location_manager">

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<application

    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
