Java is a substandard platform for substandard programmers.

This. The language and its compilation process are so suboptimal there's almost no way to recover the efficiency in the VM. The JVM bytecode isn't too bad as an interpreted code for object-oriented programs, but it loses way too much information to make it a good intermediate language for JITs or compilers like ART; barely any type info makes it through, leading to stupid hacks like generics and the "bytecode verification" phase that's a large part of why Java programs start so slowly.

The language has no way to _not_ cause massive heap and GC pressure in non-trivial programs; soft realtime applications often have to resort to implementing their own (manually-operated) stacks of common objects just to avoid constant heap churn and GC pauses in critical loops. If the PC industry hadn't still been high on the "computers will get faster forever" thing in the late 90s it would have been dumped a decade ago.

Out of curiosity, is there any phone OS (except iOS) that does not use java?

Sailfish uses Qt so it supports (Qt-flavored) C++ and QML+JS, but it's probably too ded to count.

Any hope ever of android being built from the bottom up, but without the java monstrosity? It's far better than the alternatives but there definitely are major problems. It's turning into Windows.

I think that would destroy the whole marketplace ecosystem, apps will beocme incompatible, it's not a good enough risk to take, just wait a few more years until we have 3ghz octa core water cooled 900 snapdragon with 8gb of ram to get rid of the lag.

>>58503816
is Ionic any better though?

If you want to count Windows phones, yes
