When an Android app restarts or recreates the main Activity (i.e. QtActivity) currently that leads to the app getting frozen, probably it ends up in a state when it's using the old activity's resources or the wrong surface. Qt apps could start properly supporting this case instead getting frozen or simply restarting the app to get a fresh state of execution.

Some work related to this has been already done under QTBUG-38971, but that seems to have regressed and not working as really expected and even causing other issues. Also, the fix should ideally not regress on QTBUG-124786 either.
