ART and its predecessor Dalvik were originally created specifically for the Android project
predecessor :  전신의

ART as the runtime executes the Dalvik Executable format and Dex bytecode specification
bytecode specification : 바이트코드 지정(설명서, 사양)

ART and Dalvik are compatible runtimes running Dex bytecode
compatible : 호환되는

ART introduces ahead-of-time (AOT) compilation, which can improve app performance
improve: 향상시키다.
performance : 성능

ART also has tighter install-time verification than Dalvik.
tight : 엄격한

This utility accepts DEX files as input and generates a compiled app executable for the target device
accepts : 받아들이다.
generates : 생성하다.

The utility should be able to compile all valid DEX files without difficulty
valid : 유효한
difficulty : 문제

However, some post-processing tools produce invalid files that may be tolerated by Dalvik but cannot be compiled by ART.
post-processing: 일부 처리된
invalid : 잘못된, 무효의
tolerate: 용납하다, 참다
