android – 检索数据时Phonegap相机故障

—————更新—————

似乎HTC Desire相机和这个版本的Phonegap存在某种问题.问题似乎是HTC在Android上返回相机规格的方式.

—————更新—————

我一直在使用phonegap重写我以前的应用程序的代码,但不是我需要使用相机API.当我在真正的手机上使用它时拍摄照片后崩溃了,我在SendLog中遇到了这个错误.

有谁知道为什么会这样？

这是我的Camera.js

这是我的Camera.js

var options = { quality : 75,destinationType : Camera.DestinationType.DATA_URL,sourceType : Camera.PictureSourceType.CAMERA,allowEdit : true,targetWidth: 100,targetHeight: 100 };

function capturePhoto() {
    // Take picture using device camera and retrieve image as base64-encoded string
    navigator.camera.getPicture(onPhotoDataSuccess,onFail,options);
}

function onPhotoDataSuccess() {
    // Uncomment to view the base64 encoded image data
    var theHTML = '';
    theHTML = '<div id="info">CameraSuccess</div>';
    document.getElementById('main').innerHTML = theHTML;
}

function onFail(message) {
    // Called if something bad happens. 
    alert('Failed because: ' + message);
}

希望能帮助到你

谢谢大家

解决方法

我刚刚在PhoneGap问题列表中帮助了一个有同样错误的人.我相信你错过了许可：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

来自您的AndroidManifest.xml文件.我们需要能够将捕获的图像写入.jpg文件.
