        @angelatyizhong I don't see any picture.
        What is the device where you try to install? What is the Android version on this device? What error do you get?

            @angelatyizhong API 27 is available starting with Android 8.x, see https://en.wikipedia.org/wiki/Android_version_history
            So, it can't work on Android 4.4.

                @angelatyizhong Because with Qt 5.14 you need API 21 or higher, see https://doc.qt.io/qt-5.14/android.html
                If you really need to support Android 4.4 use an older Qt version.
