你怎么在“亚行logcat”看到当你点击相机按钮中的一个？ – 2012-04-16 18:57:01

谢谢，我解决了这个问题。我尝试Phonegap1.0.0，它的工作原理。我不知道为什么。 Phonegap1.6有什么问题吗？ – 2012-04-17 09:13:22

这将是很好，找出什么问题在1.6。你可以做logcat步骤吗？ – 2012-04-17 14:23:56

对你添加的权限和相机功能在您AndroidMenifest文件？如果你没有添加，然后再试一次。

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

无论您capturePhoto()和capturePhotoEdit()功能需要有destinationType更新。

navigator.camera.getPicture(
    onPhotoDataSuccess, 
    onFail, 
    { 
     quality: 50, 
     destinationType.DATA_URL 
    } 
);

应该是这样的，

navigator.camera.getPicture(
    onPhotoDataSuccess, 
    onFail, 
    { 
     quality: 50, 
     destinationType: destinationType.DATA_URL 
    } 
);

在你的代码改变科尔多瓦版本。现在你有“cordova-1.6.0.js” 你应该把它改为“cordova-2.5.0.js” 我认为它会在那之后起作用。这样

<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>

我一直有同样的问题，我已经得到了getPhoto（）函数现在的工作，但仍无法获得cameraPhoto（）或cameraPhotoEdit（）函数工作。我已经做了几乎所有的事情在这篇文章中多听。

哦，你可以尝试这里列出的一些解决方案：

Phonegap Camera API Cannot Read Property data url of undefined
