Android ART - using .oat file in / dalvik-cache /?

Question

While playing with Android ART and the “native” .oat / .elf code file that was created during the installation of the application, I noticed something strange.

For my understanding, if the device uses ART (Android> = 5.0), the application will start with the compiled oat file (/ data / dalvik-cache / arm64 /).

This is why I was surprised when checking the fd application used and did not find the file there. Only normal apk (/data/app//base.apk) is listed here.

Check this output of my "ls -l / proc / PID / fd"

Therefore, I thought that perhaps this is simply not indicated. Therefore, I myself exchanged the ov file for this application by compiling another .dex class using the dex2oat tool.
