What is the Android Cache Fix plugin and why do I need to solve my own cache misses?
summary
The Android cache fix plugin detects real cache misses by comparing two builds and fixes specific AGP bugs: it rewrites path-sensitive task inputs (absolute→relative) via a “Gradle Monty” snapshot-and-restore workaround, converts Room’s schema arg into a command-line argument provider and shuffles outputs into task-specific dirs before merging, and disables caching for cheap copy/jar tasks that are slower to fetch than reexecution. Works across old AGP/Gradle versions, fixes many misses today, and points to AGP fixes (some require upstream changes).
