    # LIBS += -L$$PWD/firebase_cpp_sdk/libs/android/arm64-v8a
    # -lfirebase_app
    # -lfirebase_messaging

    Why did you comment this out?
    Did you fix the code?

    @jsulm That part of code fave undefined error, so I have commented that,
    first error: there are three create functions , but for android we have to call

    static App* Create(JNIEnv* jni_env, jobject activity);
    

    below app.h code:

      So, you think you can use these libraries without linking?
      You have to link these libraries. If you get "undefined error" then you have to check whether these libraries are compatible with the architecture you're using (arm64-v8a). Please link this libraries and post whole build log if the build fails.

        I'm not sure which Create function I should call.

        I am getting a lot of errors. Below are some of the errors:

            @jsulm

            I have now included those required libraries, and there are no longer any errors related to those libraries.
            The issue right now is with the code.

                  @Joshika_Namani Isn't the error message quite clear? There is no ::firebase::App::Create overload which takes two parameters of these types. The error message also tells you which 3 overloads are there, use one of them.

                      This seems to me to indicate that now your code is correct, the compiler finds the necessary matching functions in an included header file, but the link line does not include whatever you are supposed to have as a (legitimate) library (at least for that function) for FireBase apps to link against? But this is not my area, I know no more, just a suggestion.

                        @Joshika_Namani For the third time now:
                        I wrote before:
                        "f you get "undefined error" then you have to check whether these libraries are compatible with the architecture you're using (arm64-v8a)"

                        And:
                        "post WHOLE build log if the build fails"

                        Also: are there any other Firebase libraries besides the 3 you're linking?

                          right now, I'm not facing that issue and those libraries are compatible with my architecture(arm64-v8a) and got solved, My issue is with create function example :

                          app = ::firebase::App::Create(app_options,"app");

                            My issue is with create function example :

                            So, you mean the linker error (undefined reference to `firebase::App::Create(firebase::AppOptions const&, char const*)), right?
                            That error clearly says that you have a problem with the shared libs.
                            I asked you to post the whole build log so we can see whether there are any warnings from linker about incompatible libraries - you still did not post the whole log.
                            I don't have anything to add...

                                @Joshika_Namani said in FireBase and Qt6:

                                Below is my complete build log:

                                I do not know more than @jsulm and @JonB , but this log does not match with what you are actually doing. It still shows the "old" error where you tried to call a non-existing c'tor.

                                ../../main.cpp:56:11: error: no matching function for call to 'Create'
                                    app = ::firebase::App::Create(::firebase::AppOptions(), GetJniEnv(), GetActivity());
                                

                                So either you didn't saved your code file before building or you have multiple versions at the same time, or this is not the current error?!
                                I mean, you want to have working code... we can only give an advice. The fixing has to be done by you.
                                If you do the same - obviously not working - routines again and again... what do you expect? ;-)

                                First, make sure that it links to Firebase correctly.
                                Then use the API the right way...
                                ...in case of any further errors, check where they occur and see what you can do to fix it again.


                                If debugging is the process of removing software bugs, then programming must be the process of putting them in.

                                  After doing some research, I was able to integrate QtFirebase into my Qt Android application, but I am encountering the RunTime issue below. I have tried various solutions, but the issue still persists.

                                  I am encountering a runtime issue with my Android project using Qt and Firebase. Upon attempting to launch the app, it crashes with the following error:

                                  `W Zygote : Unable to open libbeluga.so: dlopen failed: library "libbeluga.so" not found.
                                  E AndroidRuntime: java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.croyance.messenger/com.croyance.messenger.Main}: java.lang.ClassNotFoundException: Didn't find class "com.croyance.messenger.Main" on path: DexPathList...

                                  The full logs can be found below. It seems that both the libbeluga.so native library and the Main activity are missing from the APK, which causes the application to fail at runtime. Additionally, there are several warnings related to Firebase initialization and some ANR (Application Not Responding) logs, which may be relevant.

                                  `W Zygote : Unable to open libbeluga.so: dlopen failed: library "libbeluga.so" not found.

                                  I have correctly configured the AndroidManifest.xml file with the following activity declaration for Main:

                                  <activity 
                                      android:configChanges="orientation|uiMode|screenLayout|screenSize|smallestScreenSize|layoutDirection|locale|fontScale|keyboard|keyboardHidden|navigation|mcc|mnc|density" 
                                      android:name=".Main" 
                                      android:label="FireBaseQTVersion1" 
                                      android:screenOrientation="unspecified" 
                                      android:launchMode="singleTop">
                                  </activity>
                                  

                                  I have followed the setup guidelines for Android in the QtFirebase documentation, specifically as outlined in the Setup.
