First I build and run MQTT on desktop OK.
Then, I tried to build with android device, I got errors mqtt module is unknown. Then I tried to build mqtt for android as desktop way, but when I run program, It had error

I guess that you need to follow the same procedure you did for building the module for Desktop, this time using the compiler/tools from the NDK

Hi @Pablo-J-Rogina,
I tried again, built as the procedure of Desktop one, there is an error:
cannot find -lc++and this was fixed by adding -nostdlib++ into .../Qt5.13.0/5.13.0/android_x86/mkspecs/android-clang/qmake.conf as
https://codereview.qt-project.org/c/qt/qtbase/+/264903/9/mkspecs/android-clang/qmake.conf#34
Then building was successful, and it works now. I will mark this issue be resolved.
Thank for your help :)
