Phonegap : android kitkat无法工作的摄像头

Question

我正在开发一个应用程序在Android摄像头应用程序。我用cordova插件添加了摄像头

config.xml

 <feature name="Camera">
    <param name="android-package" value="org.apache.cordova.camera.CameraLauncher" />
</feature>

拍照代码

 function snapPicture () {
    navigator.camera.getPicture (onSuccess, onFail, 
        { quality: 100,  
          sourceType: navigator.camera.PictureSourceType.CAMERA,
          mediaType: navigator.camera.MediaType.PICTURE,
          destinationType: destinationType.FILE_URI,
          encodingType: navigator.camera.EncodingType.JPEG,
          correctOrientation: false,
          saveToPhotoAlbum: true
         });


    //A callback function when snapping picture is success.
    function onSuccess (imageData) {
        var image = document.getElementById ('picture');
        alert("path : "+imageData);
        image.src =  imageData;
    }

    //A callback function when snapping picture is fail.
    function onFail (message) {
        alert ('Error occured: ' + message);
    }
}

该代码在所有Android版本中都运行良好，有望使用Android。在Kitkat得到的响应为“错误捕获图像”

有谁能事先告诉我Kitkat有什么问题吗?谢谢！

你在代码里犯了个错误。destinationType: destinationType.FILE_URI,将无法工作。将该行改为destinationType: Camera.DestinationType.FILE_URI,，它将运行。这是您的完整工作代码：

function snapPicture() {
        navigator.camera.getPicture(onSuccess, onFail, { quality: 100,
             sourceType: navigator.camera.PictureSourceType.CAMERA,
             mediaType: navigator.camera.MediaType.PICTURE,
             destinationType: Camera.DestinationType.FILE_URI,
             encodingType: navigator.camera.EncodingType.JPEG,
             correctOrientation: false,
             saveToPhotoAlbum: true
             })


             //A callback function when snapping picture is success.
             function onSuccess (imageData) {
                 var image = document.getElementById ('picture');
                 alert("path : "+imageData);
                 image.src =  imageData;
             }

             //A callback function when snapping picture is fail.
             function onFail (message) {
                 alert ('Error occured: ' + message);
             }
    }

我建议您使用GapDebug来调试应用程序。
