I download image file in cordova.file.dataDirectory
and I make sure file.
I use ngCordovaFile. So detail source is for understanding this problem.
In js
file:
$scope.filepath="C:/Data/Users/DefApps/AppData/Local/Packages/com.ionicframework.example/LocalState/example.jpg"
In html
file:
<img ng-src="{{filepath}}"/>
And I tried $scope.filepath="ms-appdata:///local//example.jpg"
But body is just white space. Other platforms are working (ex. android, ios).
