Android angularjs中循环解析json错误

我构建了安卓apk，并在安卓lolipop adn应用程序中安装了apk，但若应用程序安装到安卓kitkat上，它就不起作用了，只会在界面上显示白色空白的splashscreen。 我知道解析json的麻烦，但我不知道如何解决它 这是我的解析json

kaka.cari($scope.item.code).success(function(data){
                  $scope.result1= data;
                  var lat0 = parseFloat(data[0].latitude);
                  var lng0 = parseFloat(data[0].longitude);
              var map = new google.maps.Map(document.getElementById('map'), {
                zoom: 15,
                center: {lat: lat0, lng: lng0},
                mapTypeId: 'terrain'
              });
              var flightPlanCoordinates = data.map((item)=>{
                    // create new object based on current item
                    var coords = {
                       lat: parseFloat(item.latitude),
                       lng: parseFloat(item.longitude)
                    };
                    // return to new array
                    return coords;
              });
              var flightPath = new google.maps.Polyline({
                path: flightPlanCoordinates,
                geodesic: true,
                strokeColor: '#FF0000',
                strokeOpacity: 1.0,
                strokeWeight: 2
              });
              flightPath.setMap(map);
              })
              .error(function(data){
              });
           };

如果我不使用

var-flightplancoardinates

并尝试使用硬编码lat和long，它会工作，但如果我使用

var-flightplancoardinardinardinates

将在android kitkat中出错，但在

ionic serve中不会出错

这是我的json

[{"latitude":"-7.331069","longitude":"112.764192"},{"latitude":"-7.331277","longitude":"112.764198"},{"latitude":"-7.331467","longitude":"112.764186"},{"latitude":"-7.331659","longitude":"112.764159"},{"latitude":"-7.331840","longitude":"112.764154"},{"latitude":"-7.332016","longitude":"112.764133"},{"latitude":"-7.332192","longitude":"112.764112"},{"latitude":"-7.332400","longitude":"112.764101"},{"latitude":"-7.332592","longitude":"112.764074"},{"latitude":"-7.332789","longitude":"112.764074"},{"latitude":"-7.333018","longitude":"112.764047"},{"latitude":"-7.333236","longitude":"112.764042"},{"latitude":"-7.333465","longitude":"112.763994"},{"latitude":"-7.333662","longitude":"112.763956"},{"latitude":"-7.333843","longitude":"112.763838"},{"latitude":"-7.333965","longitude":"112.763704"},{"latitude":"-7.333933","longitude":"112.763747"},{"latitude":"-7.334034","longitude":"112.763608"},{"latitude":"-7.333981","longitude":"112.763297"},{"latitude":"-7.333917","longitude":"112.763018"},{"latitude":"-7.333901","longitude":"112.762723"},{"latitude":"-7.333869","longitude":"112.762444"},{"latitude":"-7.333832","longitude":"112.762127"},{"latitude":"-7.333800","longitude":"112.761730"},{"latitude":"-7.333768","longitude":"112.761473"}]

此数据控制台.log（flightPlanCoordinates）

请帮我解决我的问题

你能分享一下控制台.log（flightPlanCoordinates）产生了什么吗？是的，我已经编辑了我的问题并给控制台写信了。Logcat中有没有任何错误或异常？如果我运行ionic serve显示2个错误和1个异常，首先获取ionic.bundle.js:43929警告：尝试多次加载angular。第二个404（未找到）。和ecxeption谷歌地图API警告：SensorNotRequired
