          @OSEMO-NDJUDI have you build Qt MQTT module for Android?
          If so, have you properly referenced it in your .pro file?

                @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.

                              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?
