Qt 5.13 is not ready for Android (was QtCreator doesn't find compilers)

Gourmet

I try work with QtCreator 4.6 to build my apps on Qt 5.13. Another bug met - QtCreator cannot find compiler for Android NDK r19c. First I tried build application with NDK r12b which I successfully used during latest years. I've got compiler error message: no file type_traits to include from qglobal.h. After reading in Inet I see - this is because of NDK r12b is incompatible with latest Qt versions. I downloaded NDK r19c from this page and unzipped it to /opt folder as needed. But when I set /opt/android-ndk-r12b in Options/Devices/Android/Android NDK location and strike Apply - in page Build & Run/Compilers ALL Android compilers suddenly disappear... Only x86 32/64 bit compilers remain there. And... how?

Gourmet

Damn... I investigated android-ndk-r19c-linux-x86_64.zip - there are no ARM compilers indeed. :-(( In r12b they are but here no.

How to make ARM Android apps with this NDK?

Gourmet

I just copied non-existing binaries from r12b to r19c folders... Looks like works for while.

But while I experimented with this all - QtCreator registered lots of fake kits:

And how to clean this from red-labeled kits? Who was too much smart to disable Remove button?????....

Gourmet

Finally I've got the message. Looks like it is common for most developers who tries turn to newer Qt.

From now for me Qt 5.13 is not ready for Android application development. Probably this is a bug from older versions - some people reported same before.

@Gourmet do you claim your issue as solved? If so, please don't forget to mark your post as such. Thanks.

Gourmet

Solved???... No. It is not a solution. It's a hack and this hack unfortunately doesn't solve main problem - I cannot create working Android app with Qt 5.13.

@Gourmet I checked r20 NDK and there are Clang ARM compilers.
"Who was too much smart to disable Remove button?????...." - shouldn't you first select a Kit you want to remove? What should "Remove" button remove if you did not select any Kit?

Gourmet

@jsulm

shouldn't you first select a Kit you want to remove?

Of course I selected kit to remove. But button Remove remained inactive. It remains inactive for all auto-detected kits.

@Gourmet report is here: https://bugreports.qt.io/browse/QTCREATORBUG-22677

Gourmet

@aha_1980 this is mine report. But may be here somebody knows how to remove unwanted kits by direct file editing.

@Gourmet next time you can add the link yourself. It makes it easier for others to follow later.

Thanks and regards

@jsulm said in Qt 5.13 is not ready for Android (was QtCreator doesn't find compilers):

I checked r20 NDK and there are Clang ARM compilers.

QtCreator does not add it automatically. Just try tune QtCreator for development of multiplatform apps and it will become clear: Qt 5.12/5.13 IS NOT READY FOR DEVELOPMENT.
