AabConversionCache (Katalon Studio API Specification)

com.kms.katalon.core.mobile.aab.AabConversionCache

```
public class AabConversionCache
```
Disk-backed cache of converted AAB→APK artifacts, keyed by (AAB content hash + bundletool version) so a rebuilt bundle or a bundletool upgrade invalidates the cached artifact — the version is folded into the hash rather than kept as its own directory segment, to keep the cache path short. Stored under a dedicated Katalon-managed directory (not the OS temp dir). Each cache entry is its own subdirectory named by a short (7-char) hash — the APK file inside keeps the original .aab's base name, so tools that surface the resolved app path (Recorder, run logs) show a short, meaningful path instead of a long raw hash. Writes are atomic (convert to a temp file, then Files.move into place) so a failed or concurrent conversion can never leave a reusable partial APK visible under its final name. Bounded to {
value:
#DEFAULT_MAX_CACHE_SIZE_BYTES} bytes by default, evicting least-recently-used entries (whole directories) first.

Field Summary

Fields
Modifiers	Name	Description
`static String`	`BUNDLETOOL_VERSION`	Pinned bundletool version (STUDIO-10661) — part of the cache key so an upgrade invalidates old entries.
`static long`	`DEFAULT_MAX_CACHE_SIZE_BYTES`	Default bound: 2 GiB.

Methods Summary

Methods
Type Params	Return Type	Name and description
	`public static String`	`computeCacheKey(File aabFile)` Hashes the AAB content together with BUNDLETOOL_VERSION (so a bundletool upgrade still invalidates old entries, even though the version no longer appears as its own directory segment) and returns the first { value: #CACHE_KEY_DISPLAY_LENGTH} hex characters — short and readable, like a git abbreviated commit hash.
	`public static Path`	`defaultCacheDir()`
	`public Optional<Path>`	`get(String cacheKey, String apkFileName)` Parameters: `apkFileName` - the desired file name for the cached APK — the original `.aab`'s base name (e.g.
	`public Path`	`put(String cacheKey, String apkFileName, Path convertedApkFile)` Atomically moves `convertedApkFile` into the cache under `cacheKey`, naming it `apkFileName`, then triggers eviction if the cache now exceeds its size bound.

- Field Detail
  - public static final String BUNDLETOOL_VERSION
    
    Pinned bundletool version (STUDIO-10661) — part of the cache key so an upgrade invalidates old entries.
  - public static final long DEFAULT_MAX_CACHE_SIZE_BYTES
    
    Default bound: 2 GiB. Documented per STUDIO-10661's requirement that the limit be recorded.

  - public AabConversionCache(Path cacheDir, long maxCacheSizeBytes)
- Method Detail
  - public static String computeCacheKey(File aabFile)
    
    Hashes the AAB content together with BUNDLETOOL_VERSION (so a bundletool upgrade still invalidates old entries, even though the version no longer appears as its own directory segment) and returns the first {
    value:
    #CACHE_KEY_DISPLAY_LENGTH} hex characters — short and readable, like a git abbreviated commit hash. A collision between two different AABs sharing the same short key is astronomically unlikely for the size of cache a single developer machine accumulates, and is an accepted trade-off for a short, readable path.
  - public static Path defaultCacheDir()
  - public Optional<Path> get(String cacheKey, String apkFileName)
    
    Parameters:
    apkFileName - the desired file name for the cached APK — the original .aab's base name (e.g. app-demo.apk), so a cache hit still returns a meaningfully named path even though the entry itself is keyed by content hash.
  - public Path put(String cacheKey, String apkFileName, Path convertedApkFile)
    
    Atomically moves convertedApkFile into the cache under cacheKey, naming it apkFileName, then triggers eviction if the cache now exceeds its size bound. Returns the final cached path.
