That's a vague assertion.
Please show what you've done so far and the exact error message/condition that you've received. -

@Pablo-J-Rogina
when I run on the desktop, it works. But when I have errors when I run on Android -
@OSEMO-NDJUDI have you build Qt MQTT module for Android?
If so, have you properly referenced it in your .pro file? -

@OSEMO-NDJUDI have you checked the previous posts in this topic?
-
@Pablo-J-Rogina Yes.
you ask to follow the same procedure to create the module for Desktop, this time using the compiler / tools of the NDK.
But it's the end of the sentence that I can't understand. -
@OSEMO-NDJUDI You mean this: "If so, have you properly referenced it in your .pro file?"?
Please show your pro file, so we can check whether you properly added mqtt to your project. -

@OSEMO-NDJUDI Please post text, not screen-shots!
You use relative paths in your pro file: did you make sure they are correct? You can check compiler output to see what exact paths are passed to linker. -

@jsulm I erased the module mqt.

Project ERROR: You need to set the ANDROID_NDK_ROOT environment variable to point to your Android NDK.
Could not read qmake configuration file /home/devqt/opt/QT13/5.13.2/android_arm64_v8a/mkspecs/android-clang/qmake.conf.

I use mqtt5.13.0. By compiling mqtt5.13.0 to generate the corresponding desktop application library and Android library , the desktop application library I generated can run, but after the Android library is compiled, the Android running file runs on the mobile phone and crashes.
What shall I do?
