Question

我是科尔多瓦的新手并尝试开发Android应用程序，我需要打开相机。但我无法做到。以下是我遵循的方法：

var app = {
   initialize: function() {
    this.bindEvents();
},

bindEvents: function() {
    document.addEventListener('deviceready', this.onDeviceReady, false);
},

onDeviceReady: function() {
    app.receivedEvent('deviceready');
    document.getElementById('camera').addEventListener('click',function(e){
        navigator.camera.getPicture(onSuccess, onFail,{
            quality: 50,
    destinationType: Camera.DestinationType.DATA_URL});})
    },
function onSuccess(imageData){
    var image=document.getElementById('myImage');
    image.src="data:img/jpeg;base64,"+imageData;
}
function onFail(message){
    alert('Failed because: '+message);
}
receivedEvent: function(id) {
        console.log(id)
}
};
app.initialize();

使用Android模拟器构建和打开后，相机无法打开。请帮助我。提前致谢

app.js

// Ionic Starter App

// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)

angular.module('starter', ['ionic', 'ngCordova'])

.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)
    if(window.cordova && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if(window.StatusBar) {
