Cordovaでカメラを開くことができません

私はCordovaを初めて使い、カメラを開く必要のあるAndroid用のアプリを開発しようとしています。しかし、私はできません。以下は、私が従ったアプローチです：Cordovaでカメラを開くことができません

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();

Androidエミュレータでビルドして開いた後、カメラが開かれていません。親切に私を助けてください。事前のおかげで
