What does OAT mean?
android, android-5.0-lollipop, android-runtime
Solution
It’s Of Ahead Time, a silly reordering of Ahead Of Time. We went with that because then we say that process of converting `.dex` files to `.oat` files would be called quakerizing and that would be really funny.
Problem
We know that Dalvik uses APK, DEX, and ODEX files. And we know this abbreviation means via AOSP source or Developers site. (like this - https://source.android.com/devices/tech/dalvik/dex-format.html) - DEX means Dalvik EXcutable file. - ODEX means Optimized Dalvik EXcutable file. - APK means Android PacKage. ART (Android RunTime) uses OAT and ART, but they do not explain the meaning anywhere. Does anyone know the meaning of these shortened words?
