I think i know whats the issue if its still not fixed. My guess is that you don't use the resource system of Qt but the android application assets to store your components, the last time i had issues with this all the time was lost in the horrible slow fileengine for assets on android. It looked to me it was reopening the assets all the time which seems expensive.
I haven't tried it since 5.1 but if it is not fixed its very likely the cause of your problem. Björn Am Mittwoch, 30.
