Description
The application crash when I do many calls of lastKnownPosition() in a row.
Create a new quick project( 2.2)
Start GPS
Do 1000 call of lastKnownPosition
=> crash. It seems that java objects are created at each call of the function, even if it's the same value (this kind of behaviour must be describe in the function documentation in this case)
#include <QGuiApplication> #include <QQmlApplicationEngine> #include <QGeoPositionInfoSource> #include <qDebug> int main(int argc, char *argv[]) { QGuiApplication app(argc, argv); QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:///qml/main.qml"))); //MyGPS::test(); QGeoPositionInfoSource * source = QGeoPositionInfoSource::createDefaultSource(0); if(source) { source->setUpdateInterval(10000); source->startUpdates(); for(int i = 0 ; i < 1000 ; ++i) { qDebug() << "Before lastKnownPosition"; QGeoPositionInfo lastPosition = source->lastKnownPosition(); qDebug() << "After lastKnownPosition"; } } return app.exec(); }
