    I am making a music player app. All logics are perfect but when user press the back button app closes immediately and music stops.
    I want that if music is playing then app will run in background otherwise not.
    I can check whether the music is playing or not but unable to make app runnable in background.

    Hi,
    I am not an expert in this topic but looks like really Qt specific.
    Probably it depends on the platform and can look differently for Android/iOS.
    Quick googling shows that, at least for Android, it is supported since Qt 5.7 so should be fine.
    More info:
    Native implementation: https://developer.android.com/guide/components/services.html
    Qt bridge: https://doc.qt.io/qt-5/androidservices.html

    For iOS would check how it is natively implemented and check if adequate “bridge” is implement in Qt.
    Also searching some Qt docs for iOS could show solution.

    [EDIT]
    Looks like for iOS one of the options is to use ObjectiveC from C++ etc, some topic on the forums:
    https://forum.qt.io/topic/60597/ios-backgrounding-suspend-inactive/12
    Some official iOS docs: https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html

    Hi all,

    as Marcin’s solutions suggest, adding features that run in the background is a task that highly depends on the target platform (iOS, Android).
    There’s no ready-to-use implementation for background-running components with Felgo. It is required to rely on Qt C++ or native code parts for Android (Java) or iOS (Obj-C).

    Best,
    Günther from Felgo
