Application stopped in QML

halil sogut68

Hi,
We are using Arcgis Runtime SDK for Qt 10.2.6 and Qt 5.4.2 (MSVC 2013, 32 bit) Qt Creator QT\QML Android side We have local editing application which edits features within an offline geodatabase and sync back to the service.

After deploying application in android device after a while device ram value is getting increasing and probably in max ram value crash application and give "cbc(App name ) stopped ".Are there any mechamizm for release objects which is previously used in app or are there any other ways to solve this important problem without crash app.

Thanks

@halil-sogut68 Delete objects when not required. Use lazy loading whereever possible using Loader or createComponent.

Hi,
Can I use this Self Destroying method to sove this problem ? In this method I'm thinking to solve with using destroy() method in onRunningChanged event If not run object I call destroy method. Should I create rect object again with createObject, when I want to use again or not ? Her is the code below:

SelfDestroyingRect.qml

import QtQuick 2.0

Rectangle {
    id: rect
    width: 80; height: 80
    color: "red"

    NumberAnimation on opacity {
        to: 0
        duration: 1000

        onRunningChanged: {
            if (!running) {
                console.log("Destroying...")
                rect.destroy();
            }
        }
    }
}

Yes you will need to create the object again.
