Gralloc3: mapper 3.x is not supported error with ChartView

ovadi

Hi,
I am writing an android app and i'm getting "W Gralloc3: mapper 3.x is not supported" error when tried to use ChartView qml component.

App contains JNI and a java file to communicate usb port. Without ChartView everything works fine.

My configurations:

In Devices settings: Android settings are OK. (SDK Version: 3.0, NDK Version: 21.3.6528147)
In Kits : Android Qt 5.15.1 Clang Multi-Abi
In AndroidManifest.xml : Minimum required SDK API21: Android 5.0, Target SDK: API29: Android 10
I use my phone, Android 10 on xiomi mi A3 to deploy and run app and i'm getting error on this device.
I only have Android and Qt charts components for Qt 5.15.1. in maintaince tool. I downloaded Android components after Qt opensource server crush(maybe it affects, i don't know.)

My error message:

thanks for any help

I was using QGuiApplication app(argc, argv) instead of QApplication app(argc, argv). That was the problem about chartview. Now i switched to QApplication and i can draw charts on my phone. i learned it from: https://stackoverflow.com/questions/46471805/chartview-crash-when-launching-on-mobile-qt-qml-error

I don't get "F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 8306 (qtMainLoopThrea), pid 8277 (org.my_usb)" error anymore. But "W Gralloc3: mapper 3.x is not supported" error remains. Even i built official examples from Qt. But i will ignore it for now.
