Hallo @J.Hilk,
a lot of debug related stuff is still copied into the apk, as long as it's not signed. In fact so much, that one of my apps is nearly halved in size after signing.
A reasonable conclusion would be, that there can very well be a difference in the apk & performance between signed and unsigned.
That is good info, thanks. Almost always the apps I finally create APK files for them have both the saame size in Release and Debug mode. That could be a reason for that. I also think it's the same for both Qt and QML apps (not only QML), right?
I doubt, however, if not-signing an app will have influence on it in Release, i.e., all the garbage added to the not-signed app when building is done for the Debug mode. Hence, we finally have two option, signing the app and enjoy using it, or not signing and enjoying it in Release.
One more thing, from all experience I have through testing several apps I've been tackling, both modes have had the same behavior when testing.
Also, the two problems with the app are worked out now this way:
Using onFrameSwapped instead of Timer to solve the problem with he ball's movement speed when moving the rackets
Obtaining the velocity of the racket for each movement of it and applying it when hitting the ball to set the speed of the ball then.
:)
