我正在创建一个用于在Android手机中捕捉照片的phonegap应用程序.它适用于androID 4.x.但不适用于AndroID 2.3.x.
得到这样的错误：
抱歉!
应用程序Appname(packagename)已意外停止.请再试一次
我已经创建了项目,如上所述here并使用完整示例here.
我的phonegep HTML页面是：

默认的Phonegap(Cordova)Camera Plugin调用本机摄像头,这使得AndroID垃圾收集器可以杀死后台应用程序.这个插件可以避免你的应用程序进入后台并被垃圾收集器和其他应用程序杀死.我们使用了Phonegap源代码并对其进行了修改以避免此问题.此插件仅适用于文件URI.
