因此，每次调用getPicture时，cordova-plugin-camera都会失败，异常为“Error retrieval image”。我挖了一下，似乎我不是唯一有这个问题的人，甚至有一个pull request，我认为可能是相关的。我尝试将pull请求硬编码到插件中，但它仍然无效，错误更改为修改图像时出错。这是堆栈跟踪：

导致此问题的代码：
var opts = {
quality: 50,
destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.SAVEDPHOTOALBUM,
correctOrientation: true,
targetWidth: 680,
targetHeight: 480
};
navigator.camera.getPicture(function(res) {
console.log('Success');
}, function(error) {
console.log('Failed because: ' + error);
}, opts);
我对android开发不太熟悉，但似乎它试图将目录作为文件读取。任何想法如何解决它？
