Select image from gallery and upload to firebase failed in android but works in ios

`var imageApp = angular.module('starter', ['ionic','ngCordova','firebase']);
var fb = new Firebase("https://boiling-fire-9767.firebaseio.com/");

imageApp.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {

// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

  // Don't remove this line unless you know what you are doing. It stops the viewport
  // from snapping when text inputs are focused. Ionic handles this internally for
  // a much nicer keyboard experience.
  cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
  StatusBar.styleDefault();
}

});
})
