What is AOT and JIT in Android?

JIT converts selective part of code as and when it’s required. AOT(Ahead of time) — Ahead of time compilation, before executing your app , it converts your code to native code , so that machine (android device) can execute it natively .

Just-in-Time (JIT), compiles your app in the browser at runtime. Ahead-of-Time (AOT), compiles your app at build time on the server.2 Eyl 2019

AOT-compiled code is guaranteed to have fast startup and consistent runtime performance, with no latency during early runs. JIT-compiled code is slower at startup, but it can have better peak performance after it runs long enough for runtime optimizations to be applied.7 Nis 2020
