Description Kevin.Murray 2014-08-18 09:30:24 UTC
Created attachment 7709 [details]
Xamarin.Forms Android project illustrating the error.

I attached a simple project illustrating the issue.  I have a list of items.  Each item has a detail view you can see by tapping the item.  The detail view contains a large Grid layout, which is contained within a Frame.  This is inside a ScrollView with other controls.  Going back and forth between the list and the detail view will eventually cause an Out of Memory error on Android.  If the Frame is removed, however, the error does not occur.

Tested on both Android Simulator and a Samsung Galaxy Note tablet.

I have checked this issue and try to reproduce with the helped provided in bug description and attached sample, but not able to reproduce. I have observed different issue with the sample project.

Here are my observations:

On Simulator:
When I deploy this application on emulator its deploy successfully and worked as described in bug description.But when I click on third item that is highlighted and same time I clicked on second item the error occurred.

On Samsung Galaxy Note device: When I try to deploy the application to the device the at the time of deploy I am getting exception.

Screencast: http://www.screencast.com/t/JNzzNn1q

Comment 3 Kevin.Murray 2014-08-25 10:50:25 UTC
The simulator crash you mentioned above is the bug I mentioned.  You go into the second page, which has the Frame in it, come back, go into another, come back, try to go to another, out of memory exception.
Comment 6 Ram Chandra 2014-12-30 14:09:15 UTC
I have checked this issue and I am able to reproduce this issue.

Steps I followed:

1. Download the attach sample project
2. Build and deploy the project.
3. Going back and forth between the list.

When I navigate try to navigate in and out to the list, I observed that after few steps I am getting "java.lang.OutOfMemoryError" exception.
