IconDigger

IconDigger is an Android utility application designed to reverse-engineer installed icon packs. It allows developers and themers to inspect other icon packs by extracting their core resources—including the appfilter.xml configuration, raw drawables, and rasterized bitmaps—directly to your device's storage.

Features

• Icon Pack Detection: Automatically scans and lists all installed icon packs on your device.
• One-Click Extraction: Simple UI with dedicated buttons for different extraction modes.
• Resource Types:
  • AppFilter: Extracts the appfilter.xml file which maps app components to icon resources.
  • Drawables: Extracts the raw drawable resources (XML vectors or original images).
  • Bitmaps: Extracts icons converted into high-quality Bitmap (PNG) format.
• Organized Output: All extracted files are neatly saved to your device's Downloads folder.
