I think this is the key to making a great cross-platform solution. Pretty much any mobile app that's not a toy relies on native 3rd party sdks, be it ad providers or fancy Ui compinents. Whatever platform first solves the issue of making integration of pods on iOs or AARs on Android a smooth process, will win. I don't see any options that come close to solving this. Xamarin is not native to either iOS or Android. RoboVM (the one i work on) can cheat, as we only need to solve it for iOS, Android comes for free. React Native has no clear path for accessing 3rd party libs at all yet. Whatever they can come up with will be further complicated by the fact that the JS engine is single threaded.
