Memory leak of SfTabView control

[Konstantin]

Hi all.

I discovered a memory leak of SfTabView control. I used a simple test app with two pages. The second page contains only tabview with 2 empty tabs. I wrote a loop for navigation from first page to second one and back about 30 times.

The memory consumption increases with every next navigation forth and back, starting from a couple megabytes up to tens megabytes.

Then I deleted SfTabView control from the second page to make it absolutely clean, and repeated the test. In this case there’s no memory leak.

More over, If tabs of tabview contain inner content, the memory leak increases in geometrical progression. Although test with that content w/o tabview control doesn’t cause the memory leak.

In my real app I have a tabview with 4 tabs. Each tab contains a listview with hundreds of items (labels and images). After a series of navigation to and from, memory consumption increases up to several hundreds of megabytes. The app becomes unresponsive and finally crashes.

Tested on the Samsung Galaxy Note 10 Plus, Android 10.

Hi Norbert,

Sorry for the inconvenience caused.

Due to some technical complexity, we could not include the fix for this issue in last weekly nuget release. We will include the fix for this issue in our  Vol 1 2020 main release. Which is expected to be in end of March 2020. We appreciate your patience until then.

Hello,

Would be possible to have the solution for this issue "Memory leak in Tab View”. sooner than the end of March?

We have an application in production which is affected by this issue, which is leading the application to many crashes.

Even a workaround would be appreciate.

Thanks and reagrds

I think it's no workaround here. More over, I have checked some XF's out-of-the-box controls, and some of them also have memory leaks. It's just a total failure...

Recently I found an interesting discussion with XF team about memory leaks. It seems the problem is unresolvable at all.

At the moment I'm in doubt to use the XF in production.
