推荐答案
事实上，为了向Android用户显示图库应用，您的< input> 元素必须具有两个明确定义的属性:
As a matter of fact, in order to show the gallery app to android user, your <input> element must have two properties explicitly defined:
类型是文件，而 accept 可以是 image/* (或任何其他类型)图像相关的mime类型)
type which is file and accept which could be, as mentioned, image/* (or any image-related mime-type)
一种实现此目的的方法是自己实例化Dropzone对象，而不是依赖< form> 的dropzone类:
A way to achieve this is by instantiating the Dropzone object yourself rather than relying on the dropzone class of a <form> :
// removes the magical auto discovery of dropzone forms
Dropzone.autoDiscover=false;
// add accepted mimeTypes options (comma separated string)
// myDz is the camelCased version of the id of the element that will be "dropzoned"
Dropzone.options.myDz = { acceptedFiles: 'image/*'};
$(function(){
// instantiate dropzone on element with #my-dz id
// if no action in the form or applying dropzone on a non form (ie a div),
// you should at least pass the url in an object as the second parameter
dz = new Dropzone('#my-dz' /*, {url:"/my-upload-url"}*/);
