检索数据时的PhoneGap相机失败

Question

--------------- UPDATE ---------------

似乎there'这是HTC Desire相机和Phonegap版本的一些问题。这个问题似乎是HTC在Android上返回相机规格的方式。

--------------- UPDATE ---------------

从来就一直使用的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，它在拍摄照片后崩溃，并且发生了SendLog这个错误。

有没有人知道为什么会发生这种情况？

这是我Camera.js

这是我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); 
} 

希望它可以帮助

感谢所有的方式

------ --------- UPDATE ---------------

似乎there's某种与HTC Desire的相机问题，这个版本的PhoneGap的。这个问题似乎是HTC在Android上返回相机规格的方式。

--------------- UPDATE ---------------

此代码工作对我很好，我只有索引上的这个代码的.js引用和一个带有capturePhoto（）函数的按钮。

希望它可以帮助任何人解决他们的问题。

var pictureSource; // picture source 
var destinationType; // sets the format of returned value 

// Wait for PhoneGap to connect with the device 
// 
document.addEventListener("deviceready",onDeviceReady,false); 

// PhoneGap is ready to be used! 
// 
function onDeviceReady() { 
    pictureSource=navigator.camera.PictureSourceType; 
    destinationType=navigator.camera.DestinationType; 
} 

// Called when a photo is successfully retrieved 
// 
function onPhotoDataSuccess(imageData) { 
    // Uncomment to view the base64 encoded image data 
    // console.log(imageData); 

    // Get image handle 
    // 
    var smallImage = document.getElementById('smallImage'); 

    // Unhide image elements 
    // 
    smallImage.style.display = 'block'; 

    // Show the captured photo 
    // The inline CSS rules are used to resize the image 
    // 
    smallImage.src = "data:image/jpeg;base64," + imageData; 
} 

// Called when a photo is successfully retrieved 
// 
function onPhotoURISuccess(imageURI) { 
    // Uncomment to view the image file URI 
    // console.log(imageURI); 

    // Get image handle 
    // 
    var largeImage = document.getElementById('largeImage'); 

    // Unhide image elements 
    // 
    largeImage.style.display = 'block'; 

    // Show the captured photo 
    // The inline CSS rules are used to resize the image 
    // 
    largeImage.src = imageURI; 
} 

// A button will call this function 
// 
function capturePhoto() { 
    // Take picture using device camera and retrieve image as base64-encoded string 
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 }); 
} 

// A button will call this function 
// 
function capturePhotoEdit() { 
    // Take picture using device camera, allow edit, and retrieve image as base64-encoded string 
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true }); 
} 

// A button will call this function 
// 
function getPhoto(source) { 
    // Retrieve image file location from specified source 
    navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
    destinationType: destinationType.FILE_URI, 
    sourceType: source }); 
} 

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

Answer 2

我刚刚帮助PhoneGap问题列表中发生同样错误的人。我相信你缺少权限：

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

从你的AndroidManifest.xml文件中。我们需要能够将捕获的图像写入.jpg文件。

Answer 3

我有同样的问题，当我的AndroidManifest.xml中设置我的minSdkVersion至7时，我使用的minSdkVersion =“2”我不会遇到这个问题。

Answer 4

编辑

我原本以为我的手机，并重新安装它已经解决了该问题上清除我的应用程序。事实证明情况并非如此。我发现在尝试从相机抓取图像时，PhoneGap应用程序与Android垃圾收集一起被删除的问题。搜索了几个小时后，我最终选择的解决方案是使用foreground camera plugin。这个插件在应用程序本身内部创建了自己的相机，这样你就不必担心垃圾收集。

不幸的是，它的功能并不全面，大部分相机选项都无法提供给用户。它也只支持科尔多瓦2.4.0，这意味着我不得不从2.7.0降级。这个解决方案将适用于我当前的应用程序，希望下一个我写的将有更好的解决方案。希望这可以帮助别人！
