Runs the attack-test suite from ../src/test/java against the Android runtime, exercising the harmony based DOM and SAX factories that ship with Android. The Maven build does not include this module; it is a standalone Gradle build kept separate so the default mvn goal stays JVM only.

• JDK 17 on PATH (AGP 8.x requires it).

• Android SDK with platforms/android-34 and build-tools/34.0.0 installed; export ANDROID_HOME (or ANDROID_SDK_ROOT) to point at it.

• Either an attached emulator/device (adb devices shows it) or the AGP managed device bundled into this build (api31, AOSP system image).

• The library JAR built by the parent Maven build:

  cd .. && mvn -DskipTests package
  

Against an attached emulator/device:

./gradlew connectedAndroidTest

Against the bundled AGP managed device (downloads the AOSP API 31 system image on first run, then provisions and tears down a headless emulator for each invocation):

./gradlew api31DebugAndroidTest

The build excludes JUnit 5 tags for JAXP types Android does not ship:

• stax: there is no XMLInputFactory on Android.
• schema: there is no SchemaFactory on Android.
• xpath3: relies on Saxon, which is not on the Android classpath.

DOM, SAX, TrAX and XPath 1.0 paths are exercised in full.
