为什么我的Android应用程序中无法使用Cordova 2.7.0触发navigator.camera.getPicture？

Question

我正在开发适用于Android的Cordova应用程序，此应用程序必须从设备上传图像。 测试正在使用Android 4.0.4的摩托罗拉Xoom平板电脑上进行。
科尔多瓦版本是2.7.0。

应用程序打开并正确调用ondeviceready。

用户按下一个按钮，和下面的功能被触发：

capture: function(sourceType) { 
    navigator.camera.getPicture(this.onCaptureSuccess, this.onCaptureFail, { 
    quality: 20 
    ,targetWidth: 100 
    ,targetHeight: 100 
    ,destinationType: Camera.DestinationType.FILE_URI 
    ,sourceType: Camera.PictureSourceType.PHOTOLIBRARY 
    ,correctOrientation: false 
    }); 
} 

一旦功能被触发的菜单被示为具有4个选项来选择文件的源（ASTRO文件管理器，ES文件浏览器，文件和图片库）和以下信息添加到logcat的：

05-11 13:30:51.400: D/DroidGap(11102): Paused the application! 
05-11 13:30:51.400: D/CordovaWebView(11102): Handle the pause 

我可以选择任意的四个和logcat中显示以下信息：

05-11 13:33:57.960: D/DroidGap(11409): onDestroy() 
05-11 13:33:57.960: D/CordovaWebView(11409): >>> loadUrl(javascript:try{cordova.require('cordova/channel').onDestroy.fire();}catch(e){console.log('exception firing destroy event from native');};) 
05-11 13:33:57.960: D/PluginManager(11409): init() 
05-11 13:33:57.970: D/CordovaWebView(11409): >>> loadUrlNow() 
05-11 13:33:58.120: D/OpenGLRenderer(11409): Flushing caches (mode 0) 
05-11 13:33:58.350: D/OpenGLRenderer(11409): Flushing caches (mode 1) 

一旦我选择了图片我想上传应用程序显示一条消息“不幸的是，进程已停止。”并显示以下LogCat消息：

05-11 13:40:06.750: D/DroidGap(11886): DroidGap.onCreate()

任何想法是什么可以是我的错误？

更新：我已经更新了我与科尔多瓦2.6.0的项目，并试过上面的代码，它没有工作。 现在我已经用Cordova 2.7.0创建了一个新项目，并且刚刚从旧项目中复制了Cordova代码，并且它工作正常。

Answer 1

我在几个设备测试此代码与科尔多瓦2.7，并具有以下的结果：

Nexus 7 (4.2)      no problems 
HTC Sensation (2.3.4)    no problems 
HTC Evo 4g (2.2)     no problems 
Samsung Galaxy Tab 7.0 (4.0.4) Had the below Java error but JS seems to get the image 

（4.0.2 - 05-15 15：16：53.895：E/ActivityThread（3520） ：活动 com.android.internal.app.ChooserActivity已泄漏IntentReceiver [email protected]这是 原来这里注册是否缺少调用 unregisterReceiver（）

？

当我的同事从午餐回来时，将在Xoom平板电脑上进行测试。
