Test project demonstrating issue

## Overview

There is a report of an issue with Android Xamarin.Forms apps where an Out of Memory exception is thrown when navigating back and forth between a main page and a grid of images laid out in a StackLayout. A sample Forms app is provided. It contains two images approximately 500 x 500 in a grid on a StackLayout and a button on the main page that allows you to get to the images. Navigating to and from the image page eventually throws the aforementioned error.

The customer reports that the issue consistently appears on the LG G2 and not on his Motorola Razr Maxx. I've managed to reproduce using a Nexus 4 emulator.


## Steps to reproduce

1. Deploy app to Android device or emulator
2. Press show minion button
3. Navigate back (using hard-button or soft-button - doesn't matter which)
4. Repeat steps 2. and 3. until an error is thrown


## Expected results

Application allows user to move back and forth between main screen and screen with images as many times as necessary.


## Actual results

After navigating back and forth a number of times (observed to be between 10 and 25 times on a Nexus 4 in my tests), the application throws an Out of Memory exception.


## Additional information

This has been tested on Xamarin.Forms 1.3.2-pre3 as well as 1.3.1 and the issue still remains.

I have checked this issue with Xamarin.forms Version: 1.3.5.6333-pre1 on emulator and device(Nexus 4) both and I navigate back and forth more then 100 times and observed that its working fine. Now application allows user to move back and forth between main screen and screen without any error or exception. Please refer the screencast below:

Screencast(Emulator): http://www.screencast.com/t/EmVTMUzjfxL
Screencast(Device): http://www.screencast.com/t/ZQaSgbSqr

Note: I was also able to reproduce this issue before updating Xamarin.forms to 1.3.5.6333-pre1.
So now this issue has been fixed Xamarin.forms Version: 1.3.5.6333-pre1, and its working fine hence I am closing this issue.
