科尔多瓦网络和照相机API返回undefined [英] Cordova Network and Camera API returns undefined

问题描述

建立我的第一个科尔多瓦4.0应用程序，我真的需要一些帮助，因为我要告诉这个应用程序的演示tmrw ...

Building my first Cordova 4.0 app, and I would really need some help since I'm gonna show a demo of this app tmrw...

当我尝试访问网络信息API和照相机API（ navigator.connection 和 navigator.camera 分别），他们总是返回undefined。

When I try to access the Network info API and the Camera API (navigator.connection and navigator.camera respectively) they always return undefined.

我在我的Andr​​oid清单这些正确的：

I have these right in my Android manifest:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

和这里是安装的插件：

org.apache.cordova.camera 0.3.3 "Camera"
org.apache.cordova.console 0.2.11 "Console"
org.apache.cordova.device 0.2.12 "Device"
org.apache.cordova.network-information 0.2.13 "Network Information"

我也复制从平台文件夹下的 cordova.js 文件，并添加了＆LT; SCRIPT TYPE =文/ JavaScript的SRC =JS / cordova.js＆GT;＆LT; / SCRIPT＆GT; 标签来我的index.html。另外这里也正是我尝试访问摄像头API我的code的例子：

I have also copied the cordova.js file from the platform-folder and added the <SCRIPT TYPE="text/javascript" src="js/cordova.js"></SCRIPT> tag to my index.html. Also here's an example of my code where I try to access the camera API:

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    $(document).on('click', '.camera', function(){

        if (!navigator.camera) {
            alert("Camera API not supported", "Error");
            return;
        }
        var options =   {   quality: 50,
            destinationType: Camera.DestinationType.DATA_URL,
            sourceType: 1,      // 0:Photo Library, 1=Camera, 2=Saved Album
            encodingType: 0     // 0=JPG 1=PNG
        };
        navigator.camera.getPicture( function(imgData) { return imgData; }, function() { alert('Error');}, options);

    });
}

当我运行此我总是得到照相机API不支持警告，这意味着它是不确定的。

When I run this I always get the "Camera API not supported" alert, meaning it's undefined.

我是什么失踪？

推荐答案

所以，这个问题的答案是，科尔多瓦自动包含在项目的WWW cordova.js 文件上构建。因此，所有我所要做的就是包括＆LT;脚本类型=文/ JavaScript的SRC =cordova.js＆GT;＆LT; / SCRIPT＆GT; 标记。

So the answer to this question was that Cordova automatically includes the cordova.js file in the projects www on build. So all I had to do was include the <script type="text/javascript" src="cordova.js"></script>tag.

这是我复制​​ cordova.js 文件，包括到我的JS文件夹是不必要的。希望这可以帮助别人。

That is, my copying the cordova.js file and including it into my JS-folder was unnecessary. Hope this might help somebody.
