Privacy Browser Android 3.19.1 was released on 2 January 2025. It fixes a crash when loading the About or Import/Export activities if OpenKeychain (both About and Import/Export) or Orbot (just About) is not installed.

The cause appears to be a change in how installed packages are queried when targeting API 35 (Android 15). These activities check to see what packages are installed so they can modify the information displayed on the screen. The code that was used previously to check for installed packages now produces a crash if they are not installed. The fix is to implement additional checks to prevent the crash.
