Sorry, something went wrong.
Harden dex directory setup in RuntimeHelper with existence check and fallback to files/secondary-dexes when code_cache is unavailable. Add defensive parent directory creation in ProxyGenerator.saveProxy() to prevent ENOENT crashes on newer Android versions.

Summary
Context
ProxyGenerator.saveProxy() calls File.createNewFile() which fails with ENOENT when the parent directory is missing. The runtime constructs the dex cache path manually (<dataDir>/code_cache/secondary-dexes) rather than using Context.getCodeCacheDir(), and while DexFactory calls mkdirs() at init time, it never checks the return value.
On newer Android versions (API 28+), the OS can clear code_cache to reclaim storage, and stricter permission models can cause mkdirs() to silently fail. This was always fragile but rarely triggered on older Android versions where code_cache was reliably present.
