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

@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?

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

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]
