[HARD ERROR] Issue about UI of android 6.0

@TranVinhPhuc
you can safely ignore these warnings regarding DT_FLAGS
This is already known and shouldnt have an impact on your app

Maybe logcat logs may help here too:

// First clear the existing logcat messages
adb logcat -c
//Then reproduce the issue and save the logcat messages to a file
adb logcat -d > logcat.txt

@raven-worx !
I think this log just show about infomation of network state , it does not show about info of this error :D ...

i try to create a simple example with button and text. i deploy to my device and ...
my code qml:
import QtQuick 2.10
import QtQuick.Window 2.10
import QtQuick.Controls 2.0
Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
Button{
width: 500
height: 200
anchors.centerIn: parent
text: "THIS"

}

}

[TranVinhPhuc]

Hi All ! , i think i have same problem with this topic in Qt Forum
https://forum.qt.io/topic/72681/qt-quick-проект-не-запускается-на-эмуляторе-android

[raven-worx]

@TranVinhPhuc
the one before that one.
(regarding what they said in detail)
Note: again the DT_FLAGS warnings can be ignored and do not relate to this problem.

Do you have root access to the device?

@TranVinhPhuc
can you check how your partitions are mounted then

adb shell mount
// or
adb shell cat /proc/mounts

@TranVinhPhuc said in [HARD ERROR] Issue about UI of android 6.0:

rootfs / rootfs ro,relatime 0 0

rootfs is mounted read-only (which is ok AFAIK) .. but this is what the error complains about.

Try the following commands:

1. adb shell
2. su
3. mount -o remount,rw /

then run your app again and check if the error/issue is gone.

To mount it read-only again: mount -o remount,ro /

@raven-worx !
the manufacturer of the device confirm with me that this device using standard android 6.0 version with root right . not customized.
I was checked about device , it is using arm 32bit processor. it have related with problem ?

[TranVinhPhuc]
