I need to get the list/names of all the files (and possibly sub-directories they're located in) stored locally on an Android device from a web browser. Please note that this needs to be directly from a web browser (like Chrome/Firefox on Android) and not from an app installed on the device. I only need the names of the files, not access to them. Is it possible to do this through Flash or Javascript or another way? What are all the possible ways to do this and the best way?
Also, is it possible to determine from the web-browser if the device accessing the web-page is an Android/iOS/Windows device and, if yes, how?
