Android: Build failed with exception. Could not determine Java version from '11.0.10'

Thanks for the feedback! This is the compile output.

Anything specific to check in the project settings?

@SGaist have you experienced this before? Any feedback would be greatly, greatly appreciated!

Hi,

There was an issue in previous versions of Qt Creator with the Java version check that was a bit too restrictive but I think it has been fixed in between.

Which version are you running ?

electricjared · wrote on 14 Mar 2021, 20:33

@SGaist thanks for the reply! Qt 5.15.2

Anything above Java 8 isn't supported by Android atm.

@morte thanks for the reply!

I have tried the official releases of Java: 11.0.10 and 8u281 as well as AdoptOpenJDK 8.0.282.8 and 11.0.10.9

Think I need to downgrade even further?

It works with AdoptOpenJDK 8.0.282.8, should also work with other Java 7/8 JDKs.
What is build output with Java 8?

Thank you for the help!

Maybe something wrong with 'Compilers', it sometimes become broken after replacing JDK and Android SDK, NDK.

Working configuration looks something like that (don't mind NDK version on screenshot - 21.4, it also works with 21.3):

If problem with 'Compilers' and Re-detcting won't help, if you don't have any valuable settings, you can delete whole Qt Creator settings, located at C:\Users%USERNAME%\AppData\Roaming\QtProject or only "toolchains.xml" file. Qt Creator recreates those on startup.

I'd like to know if anyone has a follow up on this. I also have this problem but only on projects built with QML. Projects built with QWidgets and C++ build beautifully on Android, Armbian and Windows Desktop without no changes to the underlying code.

In addition I see this warning the the Android Build Settings underneath the Build directory:

Could not parse Makefile. The build will be overwritten.

I've looked at the Makefile and can't see the problem.

Sorry to dig up an old topic but this one exactly describes my problem for QML builds.

I'm having this problem too. It only happens on my "Release" build configurations. I don't get it when I configure for "Debug".

Has anyone else figured out how to resolve this?

kgregory · wrote on 31 Jan 2022, 04:17

@kgregory OK I'm noticing that this happens when I do "sign package" whether I'm in Debug or Release mode. I also get a warning on the GUI that says "Signing a debug package" in both modes.

@morte This solution helped me.
I downgraded to 8 and everything compiled.
