Changing from Qt5.12.1 to Qt5.14.1 for Android

koahnig

I am basically recompiling my app against Qt5.14.1. It was running with Qt5.12.1.

The app shows besides the icon at top a blank screen and no processing is done.

These are the settings for SDK and NDK

Has anybody an idea of what to change?

I confirmed that the source is still working when compiled against Qt5.12.1
with these settings

Same in here. Android build was running properly with Qt5.12 and 5.13, but stopped working with 5.14.1 with the same error and trace.

What's the Qt Creator version ?

Qt 5.14 has now also a new minimal QtCreator version, due to the aab changes

IIRC it was 4.11

In my case Qt Creator 4.11.1

@eduardo-paz-pix4d
ok,
does a normal hello world program work ?

ShaderEffects and FileTree examples work. I will check the differences. Thanks.

Hi @koahnig

I found the reason. There were some changes in Qt5.14 so you will probably have to update your manifest and libs.xml in order to meet the new changes.

These links were helpful to me:
