I have good news for you! Android (which never had a JVM) Lollipop replaced its old runtime Dalvik with ART, which is on around 1.5B devices. ART actually compiles Android's bytecode to ELF, though Android calls their variant OAT. OAT, in turn, is a playful anagram of AOT, because what Android now does is even more powerful than the JVM or ELF. Android includes a JIT but it also does nightly profile guided optimizations. So not only does Android perform the preloading optimization you mention for ELF but as the user continues to use their apps Android will continue to optimize the compiled binaries.
