D id you ever think, what happens when you install your app in your Android device, it shows INSTALLING for fraction of second and app get opens. What happens exactly behiend the scene? Found Interesting???? Cool !!! let’s clear all the doubt in this blog. You would have definetely read the buzz words JIT(Just-in-time) and AOT(Ahead of time) at many ocassions.

ART supports both JIT (Just-In-Time) Compilation and AOT (Ahead-Of-Time) Compilation to improve performance and efficiency. JIT (Just-In-Time) Compilation How it Works: Compiles bytecode into native machine code at runtime (when the app is executed). Stores frequently used methods in memory to speed up subsequent executions. Advantages: Faster app installation because it doesn’t require full compilation beforehand. Reduces s...
