    o I just wonder how to build MQTT correctly for Android?

    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

            @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.

                        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?
