AppStudio for ArcGIS / Map memory leaks

RodrigoPintos

Hi, I am developing a qml/js application with appstudio for arcgis v 1.3.46.
I noticed that the memory is not released properly after I push/pop a simple .qml view that has a map into an stackview .

In my android phone the application crashes after using it for a while.

I attached a video where you can see the application running in windows 10 and the task manager.

Any help will be greatly appreciated.

Ok. Thanks for investigating this. It is crashing on iOS and Android.

Thanks for the reply. I am still investigating this. We need to figure out if the isssue lies in Qt Stackview side or ArcGIS Runtime or AppStudio side. One thing we need to remember that the app is persisting the input data (images, text, controls, location etc) when we go back and forth between the pages of the stackview. Hence it is expected to have some memory increase. In other words we are not destroying the page and starting a fresh one every time we load the same page with the stackview. Are you also experiencing a crash on iOS or Android?

I'll keep you posted.

Were you able to get this resolved? I am running into similar issues.

Nakul,

Without Map control I'm not having any memory issue after push/pop.

Hi Nakul, thank you for the answer.

I do not have a map directly within the StackView, MyMap.qml is a Rectangle which has a Map Control as a child.

stackView.push({destroyOnPop:true, item: Qt.resolvedUrl("MyMap.qml")})

I'm running the QuickReport application in my pc (windows 10) and i noticed the same behaviour.

I also run it on my android phone which has not too much memory and after using it for a while it crashes.

Let me see if i can upload both videos

Why do you have a map directly within a StackView?In our QuickReport template we have a page with a Map (WebMap for 1.3 version) control. We have no issues while using Stackview push and pop. Have you looked at the QuickReport template source code? Are you having memory issues without the MapControl also while using StackView?
