Changing Android's JVM to a LLVM/C backed Compiler to smooth up android like ios
I was just curious if we can just convert the java byte code into a llvm byte code via a trans-compiler and make a custom android rom where sits a llvm compiler which then compiles the code instead of a jit compiler which is slow.
Will this process speed up android apps loading and all other features as shifting from JVM to LLVM/C backed compiler, thus a compiled app will be generated like ios rather then a Java interpreted app.

The slowness comes not from interpretation only. And Java VM has JIT anyways.

Android actually already does this nowadays, and Android N uses a hybrid AOT-JIT approach (JIT apps when used, AOT when device is idle and maybe charging)
