Ionic framework with google maps android sdk


I want to integrate google maps android sdk with ionic framework for android

I tried the cordova library specified below

but when compiling the application i get following error error: cannot find symbol
mapView.getMapAsync(new OnMapReadyCallback() {
symbol: method getMapAsync()
location: variable mapView of type MapView

i tried with blank application and then added other ng-cordova apps but if there isn’t any plugin then its compiling ok but after adding any plugin i get same error

thank you
