I wrote following sample, but getPicture cannot fire onSuccess handler.
Reproducing steps is like below.
----
Building environment
* First of all, I ran following commands.
{code}
$ cordova create myApp org.apache.cordova.myApp myApp
$ cd myApp/
$ cordova plugin add cordova-plugin-camera --save
$ cordova platform add android --save
$ cordova requirements android
{code}
* Next, run Android Studio, then choose "Import project (Eclipse ADT, Gradle,
etc.)" to above myApp directory.
* Edit two files, assets/www/js/index.js and assets/www/index.html.
{code:title=index.js}
var app = {
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function() {
app.receivedEvent('deviceready');
},
// Update DOM on a Received Event
receivedEvent: function(id) {
var parentElement = document.getElementById(id);
var listeningElement = parentElement.querySelector('.listening');
var receivedElement = parentElement.querySelector('.received');
listeningElement.setAttribute('style', 'display:none;');
receivedElement.setAttribute('style', 'display:block;');
console.log('Received Event: ' + id);
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.FILE_URI
});
}
};
app.initialize();
function onSuccess(imageURI) {
alert(imageURI);
var image = document.getElementById('myImage');
image.src = imageURI;
}
function onFail(message) {
alert('Failed because: ' + message);
}
{code}

Customize this policy to fit your own app's needs. For more guidance,
see:

Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed
for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed
for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS
vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src

{code}
* Connect Nexus 5 to My Mac.
* Try to run on Android Studio
* On Nexus 5, display camera window after allowing permissions, then take a
picture.
* You should see URL on alert. And you should see the image. But getPicture
cannot fire onSuccess handler. So I cannot see them.
