Root Cause

Android build failed. Generic Gradle failure — the real error is further up in the log output.

generic

Workarounds

  1. 95% success Scroll up in the log to find the actual error 
    flutter build apk --verbose 2>&1 | less  # search for 'ERROR' or 'FAILURE'

    Sources: https://docs.flutter.dev/

  2. 88% success Run Gradle directly for better error output 
    cd android && ./gradlew assembleDebug --stacktrace
  3. 80% success Update Gradle wrapper and Android Gradle Plugin version 
    In android/gradle/wrapper/gradle-wrapper.properties and android/build.gradle

Dead Ends

Common approaches that don't work:

  1. Run flutter clean and retry without reading the log 72% fail

    flutter clean rarely fixes Gradle errors. The real error is in the log above the exit code.

  2. Delete the android/ folder and recreate with flutter create 85% fail

    Destroys custom Android configurations (permissions, build flavors, signing)
