    hi I have a problem with an android app.

    I want to have a splash screen that is active immediately.

    but i get a flicker during apptheme drawable splash and manifest splash.

    And a flicker during qml first time overlay and fading to content.

    i do not know how to fix this behaviour.

    Hi Bas,

    we’ll have a look at this and get back to you next week, is this sufficient? We do have used another technique to implement a native Android splash screen, we need to discuss what options we have and weather to also implement this into the engine itself.

    Cheers,
    Alex

    Hi all,

    Just to be noted, I followed the same tutorial as Bas and also experience flickering. Just one time on faster device, twice on slower.

    I am waiting with more work in this area to later stage of my game, it’s not a priority at the moment.

    Despite it I would be very interested in any improvements that can be done in this area.

    We already had a look at some possible improvements, our new solution will be part of one of the next Felgo Updates then! 😉

    Best,

    Any solutions?

    I`m using “theme” splash to display it immediately at start, and splash_screen_drawable

    Between them there is a something like a theme-switch, statusbar gets visible for a while

    then there is a second flicker, before qml gets painted (a short black screen).

    seems like  https://bugreports.qt.io/browse/QTBUG-43558  is still not resolved in any way?

    Or I`m missing something?

    making my main loader synchronous, and using sticky splash with fadeout resolved second flicker 🙂

    The one remaining (it`s not so noticeable) happens when qt starts, and (as someone stated on forums) (seems to)  calls setTheme

    Android statusbar changes style, twice. From white-on-transparent to white-on-gray, and again to white-on-transparent. It happens in a few frames (~3..5)

     

    UPD: statusbar flicker resolved setting application android:theme to @android:style/Theme.NoTitleBar.Fullscreen

    The same must be stated in splash file: parent=”@android:style/Theme.NoTitleBar.Fullscreen”

    Splash is perfect now 😀

     

    …And, I think you should make some tutorial for this, it`s not so easy to non-android programmer to find this all out 🙂
