How should I define the environment variables?

In the same way they are set in Build Environment in QtCreator: "Projects/Build & Run/Build/Build Environment".

[20Stefan05]

@jsulm Thank you! But the ANDROID_NDK_ROOT variable points my Android NDK.

[SGaist]

In your terminal ?

[20Stefan05]

@SGaist
Here.

[SGaist]

Well... that's Qt Creator. You have to set them in the terminal you are using to build the module.

[20Stefan05]

@SGaist But I don't know how to do it. Could you help me?

Hi
https://www.serverlab.ca/tutorials/linux/administration-linux/how-to-set-environment-variables-in-linux/

so try
export ANDROID_NDK_ROOT=/home/stefan/Downloads/android-ndk-r19c/android-ndk-r19c
in the terminal

[20Stefan05]

@mrjj Thank you!

Does Qt 5.15.0 works with ndk side-by-side? I have ndk version 21.2.6472646 installed via Android Studio. Qt Creator keeps wanting me to install 21.2.63xxxxx version.

Where can I find which Qt version requires which NDK version?

@Sudhir-Khanger

Hi
Here
https://doc.qt.io/qt-5/android-getting-started.html

Qt 5.14.0 or later, Qt 5.13.2 or later, and Qt 5.12.6 or later
NDK r20b or r21
android-clang
Note: Qt 5.14.0 and 5.14.1 with NDK r21 have a bug fixed at QTBUG-81461.

Qt 5.12.0 to 5.12.5 and Qt 5.13.0 to 5.13.1
NDK r19c
android-clang
Qt 5.11 and below
NDK r10e

There is no version r21. There's a version 21c which seems to have issue with Qt 5.15.0

https://developer.android.com/ndk/downloads/revision_history

[Sudhir Khanger]

This is a bit problematic. There is no mention of r21 on NDK Revision History or NDK Downloads or Unsupported NDK Downloads. Qt should try to support the latest NDK which would be r21d.

@Sudhir-Khanger
Hi
but dont r21d works ?

Hi

I have my setup working with an older version of NDK which probably corresponds to r21. It didn't work for me with newer version of NDK.

@Sudhir-Khanger
Hi
This is with Qt5.15.0. correct ?

Yes, the latest version of NDK doesn't work with the latest stable version of Qt.

@Sudhir-Khanger
Hi
Ok thank you. did you try the Obsolete thing from ticket ?
https://bugreports.qt.io/browse/QTCREATORBUG-23794

Turn off "Hide obsolete Packages".
Install "Android SDK Tools (Obsolete)".

[Sudhir Khanger]

@mrjj

Those obsolete packages have been removed from Android SDK Manager and I can't seem to find them.

[mrjj]

@Sudhir-Khanger
So the "Hide obsolete Packages" is also removed ?
I did this like 3 weeks ago and it still had it there.

[Sudhir Khanger]

@mrjj Likely Google removed them. If you delete that package from the SDK Manager and also delete its folder from the disk it might also be not available for you.

The issue would go away if I install an older version of the NDK which makes me think it would be related to NDK version not being supported than SDK Tools.
