First try after installation to deploy a simple tutorial application Qt Quick controls application doesn't work

[Titi67]

Hi everybody,

I'm new and I'm a big beginner.

I try to install for 1 week Qt for android.
I can't emulate a simple Qt quick application.

The built seems to be OK, just some warnings :
Warning: QML import could not be resolved in any of the import paths: QtQuick.Extras.Private
Warning: QML import could not be resolved in any of the import paths: QtQuick.Extras.Private.CppUtils
Warning: QML import could not be resolved in any of the import paths: QtQuick.Extras.Private.CppUtils

but for Run, I have some error messages.
When I Run the first time (when the emulator is not yet launched ). The emulator is launched correctly, but the deployment of the application is'nt (error when deploy)
I Run a second time, this time in tab 3 output of application, I obtain many error maessages:
E/Trace ( 1301): error opening trace file: No such file or directory (2)

Can anybody help me please ?
Thank you in advance

[Titi67]

Is there anybody have the same issue ?
Any track, suggestions ?
I try so many things (try different versions of JDK, Qt, AVD, android)

I lost so many times.

Thanks in advance

@Titi67
don't know if it helps you in this case, but worth a try.
You may want to try enabling hardware accelerated graphics in your emulator.

[Titi67]

Omg I lost too much time. I think I'm going to give up this plateform to developp application.

[mrjj]

Does the emulator really features such good opengl support as QML requires?
Have you had anything else running in the emulator ? Not QML based?
Did u try to deply to real device ?
http://doc.qt.io/qtcreator/creator-deploying-android.html

Also as @raven-worx suggest, enable hardware accelerated graphics or check if it is
enabled. QML demands accelerated with good openGL. Not sure on android but on desktop it's
picky. Often (sometimes/it happens) the QML welcome screen refuse to load on laptops with intel chipset due to
the opengl being too old.
