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/

example

nodeenv lib
. lib/bin/activate
npm install -g ionic cordova
ionic start test1 blank
cd test1
ionic cordova plugin 
 
cd ..
git clone https://github.com/Cloudoki/ImageDetectionCordovaPlugin.git
# create pacakge.json in ImageDetectionCordovaPlugin
cd test1
cordova plugin add ../ImageDetectionCordovaPlugin
ionic cordova platform add android
ionic cordova build android
ionic cordova run android --device

example2

ionic start MyCameraApp blank --id org.csgalileo.mycameraapp
git clone --depth=1 https://github.com/cordova-plugin-camera-preview/cordova-plugin-camera-preview.git
cd MyCameraApp
ionic cordova platform add android

ionic cordova plugin add ../cordova-plugin-camera-preview
npm install @ionic-native/camera-preview --save

ionic cordova plugin add cordova.plugins.diagnostic
npm install @ionic-native/diagnostic --save

ionic cordova build android
ionic cordova run android --device

After project creation via cli (see up) import project (Eclipse, ADT, gradle) from folder <project-root>/platforms/android (choose to update gradle).

Now it is possible to develop JAVA code in Android Studio but HTML/TS has to be changed in <project-root>/src and synced with 'ionic build'

$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)

<video ng-controller="startVideo" controls="" style="width:100%; height:auto" autoplay="false">
   <source src=""></source>
</video>

.controller('startVideo', function($scope) {
  angular.element('video').attr('src','http://...');
});
