FBReader 3.8.6 for Android

This update for the 3.8 series addresses several major issues:

• File opening from third-party file managers and other applications now works correctly.
• Access to FB2 files inside ZIP archives is restored, even for non-ASCII filenames.
• In PDF mode, zooming no longer conflicts with the navigation panel.
• Overall app performance has been improved.

Additionally, this version introduces the highly requested Dark Blue interface theme — a variation of the default Blue theme with consistently dark colours. This theme is available exclusively in the Premium edition.
