Test Project

## Description

ON Android, after leaving a ContentPage with a map, where IsShwoingUSer is set to true, the app still polls for location even after the map is no longer being displayed.

## Steps to reproduce

1. Open test project and restore packages.
2. Open AndroidManifest.xml and enter your GoogleMapsAPI key in place of "YourApiKey"
3. Do whatever setting you need in Google's API console to get maps to show. (Add app to your "Key for Android Apps" in the APIs and Auth->Credentials page)
4. Launch the Android application.
5. Click on the button to open the map.
6. Note that location is polling.
7. Press the back button to exit the map

Expected result: Location polling will stop

Actual result: Location polling continues. 

## Note

The workaround would be to override OnDisappearing() for the page that displays the map and set IsShowingUser to false in that method.

I have checked this issue and with the help of attached project I am able to reproduce this issue.

I observed that when I come back form map page where IsShowingUser property is true the  app shows the Location polling when I exit from map page.

Thanks, this should be fixed in 1.3.5-pre1.

I have checked this issue with Xamarin.Forms: pre1 and I am not getting this behavior.

This issue has been fixed. Hence I am closing this issue.
