It is important to install native gradle or use gradle shipped with android studio (see PATH below)

• ANDROID_HOME=/opt/android-sdk
• PATH=/opt/android-sdk/platform-tools:/opt/android-studio/gradle/gradle-3.2/bin/

$P is $NAME/platforms/android path

• Import → “Existing Android Code …” → $NAME/platforms/android and deselect all subprojects
• Project → Build Path → Configure Build Path
  • Source → Link source → $P/Cordovalib/src with name src-cordovalib
  • Libraries → Add external JAR → $P/Cordovalib/xwalkcorelibrary/xwalkcorelibraryjavaapppart.jar * Libraries → Add external JAR → $P/Cordovalib/xwalkcorelibrary/xwalkcorelibraryjavalibrarypart.jar

Create zip file named gpio.jar and put into platforms/android/libs

lib
└── armeabi
    └── libgpio.so

build.gradle search inside libs for *jar (see dependancy section)
