v2.4.0

Cache strategy alignment and regression coverage

This release aligns the three cache strategies with their intended behavior and adds regression coverage around caching, rendering, and embedded-view lifecycle cleanup.

What changed

• MAXIMIZE_PERFORMANCE now clearly behaves as the high-retention mode:
  • reuses downloaded remote PDFs
  • keeps page bitmaps in memory and on disk
  • keeps prefetch enabled
• MINIMIZE_CACHE now behaves as a reduced-storage mode:
  • reuses the current remote PDF
  • keeps page bitmaps in memory only
  • disables disk page-bitmap caching
  • retains only one document cache on disk
• DISABLE_CACHE now behaves as a transient mode:
  • does not reuse persistent remote files
  • disables disk page-bitmap caching
  • disables prefetch
  • still keeps visible rendering correct

Bug fixes included

• Fixed incorrect remote cache retention and reuse behavior across cache strategies.
• Fixed DISABLE_CACHE so transient remote sessions no longer interfere with or delete persistent cache from other strategies.
• Fixed embedded PdfRendererView.initWithUrl(...) cleanup so transient remote files are cleaned up on lifecycle destroy, not only in PdfViewerActivity.
• Fixed stale disk page-bitmap artifacts when reopening the same document under a stricter cache strategy.
• Hardened render job and callback bookkeeping in PdfRendererCore with minSdk-21-safe logic.

Testing and regression coverage

• Added a dedicated internal CachePolicy layer to centralize strategy behavior.
• Added unit tests covering:
  • cache policy mapping
  • document retention rules
  • transient cleanup behavior
• Added hermetic instrumentation coverage for:
  • local PDF behavior under all three strategies
  • remote PDF reuse vs non-reuse
  • embedded PdfRendererView lifecycle cleanup
  • strategy downgrade behavior for stale disk bitmap cache
• Added a debug-only embedded host activity used to verify PdfRendererView cleanup outside PdfViewerActivity.

Compatibility

• No public API breaking changes.
• Existing CacheStrategy APIs remain the same; behavior is now more consistent and predictable.
