Root Cause

Android resource merge failed. Duplicate resources, invalid XML, or AAPT2 crash.

generic

Workarounds

  1. 92% success Check the full error output for specific resource conflict 
    Run: ./gradlew mergeDebugResources --stacktrace  # shows exact conflicting resource

    Sources: https://developer.android.com/build/

  2. 88% success Search for duplicate resource names across modules and libraries 
    grep -r 'resource_name' app/src/main/res/  # check for duplicates in values/, drawables, etc.
  3. 82% success Invalidate caches and restart (File > Invalidate Caches) 
    Android Studio: File > Invalidate Caches > Invalidate and Restart

Dead Ends

Common approaches that don't work:

  1. Clean project repeatedly (Build > Clean) 65% fail

    Clean removes build cache but does not fix the underlying resource conflict

  2. Downgrade Gradle plugin version 72% fail

    Masks the issue temporarily; the resource conflict still exists and will reappear
