Bug

App crashes when starting compression/extraction if too many files are selected. Cause: ~1.84 MB payload passed via Intent.putExtra() exceeds Android Binder limit (~1 MB).

Steps to Reproduce

1. Select a large file set (many files / long paths).
2. Tap Compress/Extract.
3. App crashes immediately.

Expected

Foreground service should start and run the task without crashing.

Analysis

• Binder transaction = 1,841,280 bytes → exceeds limit.
• Crash at ContextImpl.startForegroundService().
• Root cause: full file list/metadata passed directly in Intent.

Fix Suggestion

• Don’t use putExtra() for large data.

• Instead:

  • Save data to a temp file and pass only its path, or
  • Store list in an app-wide cache/singleton and pass only a key.
