and .js

.controller("examplecontroller", function($scope, $cordovacamera) {      $scope.takepicture = function() {         var options = {              quality : 75,              destinationtype : camera.destinationtype.data_url,              sourcetype : camera.picturesourcetype.camera,              allowedit : true,             encodingtype: camera.encodingtype.jpeg,             targetwidth: 300,             targetheight: 300,             popoveroptions: camerapopoveroptions,             savetophotoalbum: false         };          $cordovacamera.getpicture(options).then(function(imagedata) {             $scope.imguri = "data:image/jpeg;base64," + imagedata;         }, function(err) {             // error occured. show message user         });     }  });

the camera works well, photo shows in camera tab, , need show in filters , share tabs too

thanks!

    $cordovacamera.getpicture(options).then(function(imagedata) {         $scope.$apply(function () {             $scope.imguri = "data:image/jpeg;base64," + imagedata;         });                 }, function(err) {         // error occured. show message user     });

you have use $scope.apply apply changes in $scope variable.
