From the perspective of the user or app developer, they do not care. When they see an app perform slower on another platform for whatever reason they will complain. Maybe the problem was Java in Android (along side its sheer fragmentation) all along. Hardly any complaints about any of that for iOS.
No wonder that is the reason why they are preferring to moving everyone to use Dart / Flutter in their future operating system instead of continuing to use Java.
It is like as if Android was designed to be a disaster.
It's both of their fault; including the entire Android system design and Google knows it.
It's evident that Google and many developers have had enough of it from the runtime, Java, JDKs and the whole system. Otherwise, why on earth are they planning to move away from it all in the first place?
Once again, from the perspective of the user or the app developer, they don't care, Android still just doesn't cut it against iOS. No wonder Android is always second place.
