Is it possible to choose documents from iOS, and Adndroid device without using HTML <input>

I’ve researched this and come to the conclusion that you can use a plugin like this that allows you to choose a document from a third party service dropbox but their is no way to choose a file from iOS storage unless you use <input> and only returns a file object but does not have access to the file URI just like if you were using HTML/Javascript in the browser. Am I correct in my conclusion?

What happened to the android file chooser plugin? I don’t see it listed under the plugins anymore
