OutOfMemoryException was unhandled by user code

[Ela]

I am trying to update secondary tiles of my application usingLiveTileHelper.UpdateTile method. Some of the secondary app tiles are updated but my app gets stuck updating any one of the tile in between with this exception: 

OutOfMemoryException was unhandled by user code
on the method: LiveTileHelper.UpdateTile(tile, flipTileData);

What do I need to do to get this working on all secondary tiles?

Thanks

Hello Ela,

Thank you for your question.

We are not aware of a similar exception caused by the UpdateTile method. When you update a tile, a new image is created with the details that need to be displayed so if your application is already using a lot of memory and is close to the memory limits, the new image that is created from the tile might be passing the limits. It would be great if you share some more info about the scenario where this occurs and it would be best if you could send us a project that illustrates how this issue occurs. It could help us to easily understand what's the cause and assist you faster.

I can confirm the exception, some of my users are reporting that their live tile is not updated correctly - sometimes. From the stacktraces in Dev Center, I can see that is usually crashes around method "SaveTilesData" and somewhere inside XmlSerializer

Hello Tomas,

I'd like to ask you for a little more details on your scenario. Is your application targeting WP7 or WP8? Also what type of tiles do you use - Standard, Flip, Cycle or Iconic? The last thing that I'd like to ask you to share are the Exception type and the Problem function that are stated in the Dev Center report.

Thank you for your cooperation.
