Question

I'm building Ionic application that have geolocation (Google Api), but that's irelevant, in upper right corner is button which i want to make to take screenshot and automatically make popover with options to send that screenshot image via email, viber..., but i don't have an idea how to take that screenshot, I googled and googled without any luck, please help.

app.controller('MapCtrl', function($scope, $cordovaGeolocation, $ionicLoading, $ionicPlatform) {

    $ionicPlatform.ready(function() {

        $ionicLoading.show({
            template: '<ion-spinner icon="bubbles"></ion-spinner><br/>Acquiring location!'
        });

        var posOptions = {
            enableHighAccuracy: true,
            timeout: 20000,
            maximumAge: 0
        };
        $cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
            var lat  = position.coords.latitude;
            var long = position.coords.longitude;

            var myLatlng = new google.maps.LatLng(lat, long);

            var mapOptions = {
                center: myLatlng,
                zoom: 16,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            };          

            var map = new google.maps.Map(document.getElementById("map"), mapOptions);          

            $scope.map = map;   
            $ionicLoading.hide();   

            var marker = new google.maps.Marker({
            position: myLatlng,
            map: map,
            title: 'Lokacija'
        });


        }, function(err) {
            $ionicLoading.hide();
            console.log(err);
        });
    });               
});

Answer 1

Two options, as far as I can tell:

• Use a third-party Cordova plugin, such as https://github.com/gitawego/cordova-screenshot - this will most likely include the application's UI elements too, though, which might not be what you want.
• Perhaps a better idea would be to use the Google Static Maps API - you can pass the current parameters from your dynamic map to it, and it'll return an image version.

This should get you started: How to take a screen shot in ionic

After you received the picture from the plugin, you can just use ionic's popover service to display it there.
