You should notice a performance drawback when running ARM code on x86. The Houdini engine is good, but it cannot do magic. Whether that's significant or not, will depend on your usage and often on how much code you're running natively, versus Java. Given that there are a number of x86 performance optimisations in QtCore (far more than for ARM), you're leaving a lot on the table by shipping only ARM binaries. > Is it still advisable - to have to different kits and provide > two different APKs in order to deliver for both architectures?
