    <!-- 1. Standard Coarse and Fine Location Permissions -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <!-- Optional: If your app is only using the location button to access 
    location, you should add the "onlyForLocationButton" flag shown below to
    your ACCESS_FINE_LOCATION declaration.

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

    Note: Adding this flag restricts your app from accessing the precise 
    location permission via the broader permission, and that users will be 
    required to use the location button in order to share precise location with 
    the app. This is designed to improve user privacy & trust when granting location access.
