+===== Android Studio =====
+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'
