后来发现获取的地址uri是编码过得，我要获取本地的路径下面是完整版的

//调用原生文件系统管理器并选取文件获取文件地址

window.PickFile = function(callback, acceptType) {//acceptType为你要查的文件类型"image/*"，"audio/*"，"video/*;image/*"  // intent.setType("image/*");//intent.setType("audio/*"); //选择音频//intent.setType("video/*;image/*"); //选择视频 （mp4 3gp 是android支持的视频格式）
