Description Yeahpoint 2015-06-05 05:55:51 UTC
I have created a xamarin project with forms. Where I use the MasterDetail page class to navigate to the different pages in the application. My Homepage is a Carousel page that loud 3-4 image. When I navigate back to the homepage I get the following message:
[dalvikvm-heap] Grow heap (frag case) to 30.969MB for 8305932-byte allocation

every subsequent navigate back to the Homepage (Carousel Page) increases the Heap size. the size of the increment is dependent on the number of images I load into the carousel page.

After 4 or 5 navigation actions I receive the following exception:

Thank you for taking the time to submit the bug. If you could please attach a reproduction to the bug by starting with a clean Xamarin.Forms project and adding just the code necessary to demonstrate the issue we would very much appreciate it.

Warm regards,
Xamarin Forms Team

Carousel out of memory

I have created a new Forms project using a masterDetailsPage to navigate between pages. If you navigate to and from the carousel page a few times an out of memory exception is thrown.

status changed
Comment 5 Niels 2015-06-20 10:53:21 UTC
Same problem on Windows Phone: out of memory exception if more than 6 or 7 pages in CarouselPage (depending on the page size).

Comment 6 Jason Smith [MSFT] 2015-06-26 03:48:22 UTC
Should be fixed in 1.4.4-pre1
Comment 7 Parmendra Kumar 2015-07-17 14:03:46 UTC
I have checked this issue with X.F 1.4.4-pre2 and its working fine at my end.

hence closing this issue.
